METALLICS

BISMUTH There is no recorded production for Ontario in 1968.

CADMIUM Production of cadmium in Ontario started in 1964, with 187,604 pounds valued at 5607,853. By 1968, it increased to 2,732,729 pounds valued at 57,788,278, or by 1,356.6 percent. When compared to 1967 output, the 1968 production of cadmium increased 35.02 percent or from 2,024,006 pounds in 1967 to 2,732,729 pounds; at the same time, its value increased 37.43 percent from 55,667,217 to 57,788,278.

GOLD The output of gold in the 1964-1968 period declined by 36 percent. The main reason for this decline may be attributed to substantial depletion of gold ore reserves, accompanied by an increasing cost of mining in the presence of the fixed price for gold. In 1968, there were 23 mines operating in Ontario, including Wilmar Gold Mines which commenced production in January, and Surluga Gold Mines Limited which began producing in October. During 1968, four gold mines terminated operations. These were Hollinger Mines at Timmins, Preston Mines in Tisdale Township, Teck-Hughes Division of Teck Corporation, and Lake Shore Mines, both in the Kirkland Lake area. The latter terminated gold production from tailings, which they had processed intermittently since 1964. The mines reported milling 4,638,252, tons of ore, recovering 1,309,159 ounces of gold and 329,232 ounces of silver, for a total value of 550,129,900. The average recovery value per ton of ore milled was 510.81. Gold recovered as a by-product of the nickel-copper operations amounted to 62,187 ounces and of the base metal operations to an additional 8,433 ounces. Thus, the total production of gold in Ontario in 1968 amounted to 1,379,779 ounces valued at 552,031,466 a decrease of 7.73 percent in volume and 7.83 percent in value, from the 1,495,385 ounces produced in 1967, valued at 556,450,784. In 1968, the 23 gold mines operating in Ontario employed 5,542 people and paid them 529,900,015 in wages and salaries. 3 Annual Report for 1968

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968.

Production Ore broken and drawn off from stopes amounted to some 208,400 tons and about 2,600 tons of broken ore were remaining in stopes at the year end. Stope preparation and development work produced an additional 61,700 tons. Improvements in mining operations resulted from the availability of classified mill tailings for backfilling in more working places. Stopes which were formerly supported by square-set timbers were changed to the cut-and-fill mining method to obtain a higher rate of extraction. Wooden floors were replaced by cemented-fill floors in the cut-and-fill stopes to facilitate use of new mucking and drilling equipment. The rate of production for stoping and stope preparation work was raised.

Development The heavy program of preparation work which began in 1967 to provide new stopes below the 2,900-foot level in replacement of those mined out above was continued. Diamond-drilling at a reduced rate was continued between the 3,000-foot sub-level and the 3,700-foot level.

Ore Reserves At l January, 1969 ore reserves were estimated at 865,000 tons averaging 0.32 ounces of gold per ton without allowance for dilution, compared to 819,000 tons and 0.33 ounces at the beginning of 1968.

The Cochenour Mine The mine continued to provide the majority of the tonnage supplied to the mill during 1968, but at a much reduced rate and grade than in previous years. This reduction results from the depletion of the developed ore on the Cochenour, and it can be expected that a further decline from Cochenour will be noted in 1969. The upper level "clean up" program was increased during the year to compensate for depletion of the ore on lower levels. Several small blocks were discovered which are continuing to produce at a modest rate and grade. Diamond-drilling continues to search for these blocks on the upper levels. The chert and north-south structures that grade between 0.15 and 0.25 ounces gold per ton, pro vided most of the ore supplied by the Cochenour mine in 1968. These structures were under develop ment on the 19th and 20th levels during 1968 and the program continues; this is known as the "04 area. Diamond-drilling confirms continuity to the 22nd level. The cut-off grade in these structures for low cost mining blocks is calculated to be 0.16 ounces gold per ton, which grade of ore can be economic only if the overall operation is at full capacity and the fixed costs are reduced to a minimum per ton distribution as a result. In the west mine the diamond-drilling program has been inconclusive. Values and arsenopyrite mineralization are present, but so far have been too erratic to make ore. This area will be investigated further by drilling.

The Annco Mine Production from this property during 1968 totalled 27,922 tons grading 0.368 ounces gold per ton, representing 76.3 tons per day and 28 percent of the ore milled by the Cochenour mill. In 1967 Annco shipped 39,924 tons grading 0.414 ounces gold per ton. Ore developed and available for mining above the 2200-foot level is calculated to be approxi mately 50,000 tons grading 0.40 ounces gold per ton. Exploration for down dip extension of the talcose ore zone below the 2200-foot level has established the mineralized zone to a depth of at least 175 feet below this level. The next horizon (2350) would require 3,000 feet of crosscutting and drifting to open up the ore zone, the cost of which is prohibi tive for the one zone. Cochenour are exploring the "04" chert and north-south structures on the 2200-foot and if further depth work is warranted, consideration will be given to drive the 2350-foot crosscut for the mining of the Annco and Cochenour structures. Annual Report for 1968

The Wilmar Mine The Wilmar mine increased its production substantially during 1968 and is expected to provide more than 50 percent of the mill feed to the Cochenour mill in 1969. Production was 28,018 tons grading 0.249 ounces gold per ton during 1968. The drifting program continued in early 1969 until the No. 6 east ore zone was reached. Stope preparation on this ore block is underway. Mining operations progressed on the 1300 and 2050-foot levels. The stoping blocks are of good dimensions and mining costs continue to improve. Hydraulic classified tailings are being used for backfill in the 2050 6E stope, while other slopes are being mined by shrinkage methods. Backfill stoping, being of a cyclic nature, results in mill feed shortages when only one stope is mined by this method. The new 1900-foot level production will alleviate this problem. An in-stope load haul dump unit has been purchased to provide greater efficiency in the movement of the ore, over slusher- scraping in the wide Wilmar ore bodies, and is expected to be in operation on the 2050-foot level May 1st. A similar unit will be considered for the 1900-foot level. Diamond-drilling has indicated substantial tonnages of ore on the Wilmar. Development to date has been up to expectations and the increased productivity of this property is expected to provide the necessary tons required for the overall stability of the operation.

The Consolidated Marcus Exploration No exploration was undertaken on this property in 1968.

A total of 159,166 tons of ore was hoisted; 158,792 tons were milled at a daily average of 463 tons per operating day. 17 Annual Report for 1968

Company Annual Report The following, pertaining to the Hollinger and Ross mines, was taken from the company annual report for the year ending 31 December 1968. Value of bullion production from the Hollinger mine in Timmins and the Ross mine in Holtyre declined from 35,671,559 in 1967 to 32,259,760 in 1968. Milling of ore ceased at the Hollinger mine on 24 July 1968. The value of the bullion recovered from ore processing and mill clean-up at the Hollinger was 31,371,190. The total value of bullion production at Ross mine was 3888,570 in 1968 compared to 5821,202 in 1967. The mill treated a record 158,729 tons during the year, an achievement made possible by improved mining practices and more effective use of the milling plant. The loss from gold mining operations before expenditures on outside exploration and depreciation was 3862,084. The loss was largely offset by the Emergency Gold Mining Assistance payments of 5629,649 and sundry income at Hollinger mine amounting to 3127,422. The 1968 results show the continuing dependence of the Ross mine on Emergency Gold Mining Assistance payments. Without this aid, the mine which employs more than 100 and provides the main economic support for an established community of some 600 people, could not continue to operate. Following the cessation of milling at the Hollinger mine, shafts and other mine openings were securely covered or fenced. A few buildings have been demolished. A large number of company- owned houses and a considerable quantity of mining equipment have been sold. The office building and the mechanical shops are still in use. The latter facility is used as a repair shop for Ross mine and accepts work from a number of local customers. Inevitable as it was, the end of the Hollinger mine closes a brilliant chapter in the annals of Canadian mining. For many years, the Hollinger was Canada©s largest gold producer. With a history of experiment and innovation, and generous with its acquired knowledge, the Hollinger contributed a great deal to the progress of mining in Canada and abroad. It is a source of satisfaction to all share holders and all who have shared in the Hollinger management that this fountainhead of Hollinger economic strength could close without adversely affecting the earnings of the company. Proven ore reserves at the Ross mine at the end of 1968 were estimated at 537,000 tons, having a grade of .185 ounces per ton. The work force numbered 108 at year-end. Turnover of employees was much lower than during the previous three years and this condition helped to make possible the record production rate for the year. Although Hollinger mine is closed, some revenue will be derived in 1969 from use of the shops, from leasing and sale of mine equipment and houses, and from the mining of ore in the boundary on the deeper levels by Mcintyre Porcupine Mines Limited. The shaft-sinking program to search for additional ore at Ross mine will continue hi 1969. The cost of this work will offset much of the additional income expected from higher bullion production and, while a small profit is possible in 1969, it is anticipated that normal profit levels will be reached hi 1970.

Employment and Management The average number of employees at the Hollinger Timmins mine was 253: 74 under ground and 179 on surface. C. B. Ross was general manager. The average number of employees at the Hollinger Ross mine was 111: 51 underground and 60 on surface. J. J. Caty was resident manager.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. During the year 1968, 510,474 tons of ore were milled at an average rate of 1,395 tons per day. The average grade was 0.36 ounces of gold per ton, down from the 0.39 ounces per ton grade of 1967. The value of production was S6.82 million, down 5720,000 from S7.54 million in 1967. The overall recovery of gold in the milling operation was 97.3 percent. The decreased tonnage treated, the increased proportion being mined by underhand square-set and undercut-and-nll, and the higher labour costs are reflected in the increased cost of 71 cents per ton. The rising costs of material again affected the costs of mining during 1968 with an increase of more than 10 percent in the cost of over 50 percent of the materials used. Ore broken by square-set methods accounted for 67.9 percent of the total ore compared to 68.4 percent in 1967. Undercut-and-fill tonnage increased to 55,738 tons or 11.2 percent of the ore broken. Pillar ore represented 38.3 percent, down slightly from the 39 percent for 1967. At the end of 1968, proven ore reserves including allowances for dilution, were as follows:

Ounces of Gold Tons Per Ton Total reserves at the end of 1968 3,249,128 0.46 Total reserves at the end of 1967 3,750,329 0.45

The total work force decreased from 715 to 704 and the underground work force increased from 473 to 489. With a general wage increase effective l November and an additional increase to all production workers underground, the labour situation stabilized and the work force reached full complement in November. Seventy percent of employees on the payroll 31 December 1968, had more than one year of service with the company. A third training program under the Department of Labour was started in August. Since the inception of these training programs in 1967, 206 men have completed their training. Timber continues to be the major material cost item. During 1968, 5.68 million board feet of lumber were consumed compared to 6.19 million board feet in 1967. Consumption of timber per ton milled is 11.1 board feet. From the commencement of milling in May, 1938 to the end of 1968, production was 8,623,727 ounces of gold with a value of 5309,483,652 from the treatment of 32,473,774 tons of ore with an average gold content of 0.266 ounces per ton. 19 Employment and Management The average number of employees was 727: 492 underground and 235 on surface.

New construction in 1968 consisted of the following: a power transmission line from Mcintyre substation to Hollinger central shaft, a 12 inch, wood-stave pipe line to carry mine water from Hollinger central shaft to Pearl Lake; two wooden flumes for drainage control; filling, levelling, compacting and grading of a new parking lot at No. 7 shaft. A total of 329,010 tons of gold ore was hoisted and milled; 719,710 tons of copper ore was hoisted and milled. Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. During the year 719,710 tons of copper ore were milled from which 10,682,000 pounds of copper and 11,891 ounces of gold were recovered. Gold ore milled totalled 329,010 tons for a production of 93,187 ounces of gold and 9,017 ounces of silver. Value of metals produced was S9,737,000. Operating income with Emergency Gold Mining Assistance and after write-offs was 52,146,000. Following the closing of the Hollinger mine, operation of their pumping system was taken over in August. A lease was also obtained for the development of mining of any ore left on the property. Work under this agreement has shown some encouraging results and is continuing. During the year the work force was decreased by 47 men. This reduction was made possible by changes in organization and should result in a more efficient operation. Copper Development Development totalled 17,734 feet comprised of 13,995 feet of lateral work and 3,739 feet of raising. Of the above total 14,720 feet were for stope preparation and 3,014 feet for permanent haulage ways, ore passes and ventilation openings. Diamond-drilling amounted to 24,145 feet. Additional drilling was done on the downward extension of the copper zone on the Westfield Minerals property. The area above the 3,625 level is now being prepared for stoping. Gold Development Lateral development totalled 1,116 feet with 252 feet in ore averaging 0.352 ounce per ton over a width of 6.9 feet. Production from the Hollinger lease was 49,037 tons or 15 percent of the total. Approximately 22 percent of the production consisted of broken ore salvaged from old shrinkage slopes. Although this material was of low cost, inclusion did result in some reduction in the mill head grade. 27 Annual Report for 1968

During the latter part of the year mining in the number 15 shaft area was temporarily discontinued to consolidate operations in other areas. Workings in this area are being maintained so that stoping can be resumed if economic conditions warrant.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. Lateral development consisted of 2,815 feet of exploration in lava formations, 1,675 feet in east greywacke and 725 feet in conglomerate. Some 1,415 feet of the drifting was in ore averaging 0.11 ounces of gold per ton over drift width. Exploration of the lavas accounted for 88 percent of the drilling and indicated a mineralized zone between the 2400-foot and 2600-foot levels which is estimated to contain 500,000 tons averaging 0.13 ounces of gold per ton. This zone is open downward and to the west, and is in the same structure as the wide, disseminated zone between the 1200-foot and 1600-foot levels. Drilling from the 1600-foot level to date has indicated that the upper and lower zones are not connected. Approximately 7 percent of the drilling explored conglomerate and only a small tonnage of ore was outlined above the 1600- foot level, east of the shaft. The remainder of the drilling was in east greywacke and indicated a vein on the 1600-foot level, west of the shaft, which extends at least 100-feet above the level.

Stoping Stoping was carried on in the east and west sections of the mine with the east end accounting for 83 percent of the tonnage mined. About 19 percent of the ore was produced from lava formations. Some 46 percent of the ore milled was mined from long-hole open slopes; 40 percent from shrinkage slopes; 10 percent from flat-dipping slusher slopes and only 4 percent from cut-and-fill stopes.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The company's gold mining operation at South Porcupine was terminated during the year. The last ore was hoisted on 31 May and after saleable equipment and materials were brought to the surface, the underground workings were permanently closed. Following completion of milling opera tions, the plant was cleared of all gold bearing material and placed on a care and maintenance basis. In 1968,11,968 fine ounces of gold were recovered from the 48,590 tons of ore milled and from the clean-up of the mill after operations ceased. Average mill head grade was 0.249 ounces per ton and the average mill recovery 96.6 percent compared to 0.201 and 95.6 percent in the previous year. The average grade of ore was higher mainly because a portion of the reserves was not mined since the grade was too low for profitable production. AU townsite houses are rented on an economically self-sustaining basis under short term arrange ments while negotiations are in progress for eventual disposal. The small remaining staff are readying salvaged equipment and materials for sale as well as being engaged in fire protection duties. The pro gram is proceeding satisfactorily and on-site expenditures are progressively being reduced to a minimum. Employment and Management The average number of employees was 56:25 underground and 31 on surface. J. Engstrom was mine manager.

Company Annual Report The following is taken from the company annual report for the year ending 30 September, 1968. The Teck-Hughes gold mine at Kirkland Lake raised its last ore to surface on 31 January, 1968, after 51 years of production. Clean-up operations continued until May, and the plant, equipment and buildings are now being sold. Teck-Hughes was discovered in 1913 by James A. Hughes and Sandy Mcintyre, the prospector who gave another important mine and company his name. During its life, Teck-Hughes produced gold with a gross value of 5107,856,640 and paid dividends of 551,764,259 to its shareholders. The mine created employment directly and indirectly for thousands of Canadians and was, along with others, one of the cornerstones upon which the City of Kirkland Lake was built.

Employment and Management The average number of employees was 27; 3 underground and 24 on surface. G. G. Gilchrist, mine manager, at Teck-Hughes for the past 23 years died in June 1968. Mr. Gilchrist was a respected member of Canada's mining community and deserves credit for the efficient operation of Teck-Hughes during his management. K. C. Griffin was appointed acting manager in May.

Upper Canada Mine Diamond-drilling on the "L" zone below the 6,150-foot level was continued in 1968. Results seem to show that the "L" zone ore bodies re-occur below the 6,150-foot horizon with no decrease in grade. The depth capacity of the present hoisting plant will enable the establishment of six new levels at 150-foot intervals. Ore developments on the 2,750 "C" zone, and diamond-drill intersections below this level, are favourable enough to warrant development of this zone to greater depths.

An additional 1,075.027 ounces of gold was recovered from the Upper Canada cyanide circuit. Recovery was 95.02 percent of the gold and 96.27 percent of the copper. Improvement in milling practice resulted in a small increase in mill capacity. The mine production was handled with the mill running at 92.31 percent of possible running time.

Employment and Management The average number of employees was 278: 174 underground and 104 on surface. J. H. Botsford was general manager.

WILMAR MINES LIMITED Wilmar Mines Limited was incorporated in September 1958 with an authorized capitaliza tion of 3,000,000 shares of 95^ par value; all shares have been issued. The directors and officers were: E. C. Cochenour, president and director; C. E. Mooney, M. C. Mosher and S. J. Zacks, directors; J. E. J. Fahlgren and G. T. Smith, vice-presidents; J. B. McLellan, secretary. The head office and mine address is Cochenour. The property comprises 675 acres adjoining the Cochenour Willans property in Dome township, Red Lake area, District of Kenora and is controlled by Cochenour Willans Gold Mines Limited. The vertical, four compartment winze located in claim KRL 8583 was collared 1,265 feet below the collar of Cochenour No. l shaft; it is 816 feet deep and reaches a depth of 2,081 feet below surface. Development work in 1968 consisted of 781 feet of drifting and 87 feet of raising. Total development footage to 31 December 1968 was as follows: 8,021 feet of drifts, 5,767 feet of crosscuts and 1,432 feet of raises. Some 32 diamond-drillholes totalling 2,081 feet were completed from underground. A total of 28,018 tons of ore was hoisted and milled at an average of 77 tons per working day in the Cochenour mill. 38 Volume 78

Company Annual Report See Cochenour Willans Gold Mines Limited, for further information contained in that company's annual report for the year ending 31 December 1968, which pertains to Wilmar Mines Limited. Employment and Management J. E. J. Fahlgren was general manager, and the operation was carried on by the Cochenour Willans organization. IRON ORE The overall output of iron ore in Ontario has increased by 35.5 percent from 8,046,769 short tons in 1964 to 10,907,197 short tons in 1968. With the exception of a slight drop in production during 1966 the iron ore production has been increasing steadily. Ontario's iron ore production in the 1962-1966 period averaged 21.4 percent of Canada's total iron ore output. In 1967 and 1968, the iron ore output represented 20.4 and 23.0 percent, respectively, of the Canadian total. In 1968, it increased by 26.1 percent from its 1967 production level. At the same time, the production value increased 27.3 percent, from 599,903,925 in 1967 to an all time record 5127,137,824, in 1968. Nearly 60 percent of the 1968 production, came from the Rainy River, Kenora and Sudbury districts. The rapid development of the iron ore mining industry in Ontario to its present position is largely due to the introduction of the iron ore pelletizing process. The excellent physical characteristics of iron ore pellets and their extremely uniform qualities permit smooth and predictable blast furnace operation, thereby reducing costs of pig iron. A major advantage of the pelletizing process is that it makes possible the utilization of low-grade ores. Total number of employees in the iron ore mining industry of Ontario increased to 3,485 in 1968 from 2,869 in 1967 or by 21.5 percent, and the total payroll increased to 527,024,063 from 521,067,987 or by 28.3 percent.

Ruth and Lucy Mine The property comprises 47 claims in Townships 28 and 29, Range 24, District of Algoma. The Ruth and Lucy mine is located about 3.5 miles east of the Sir James open pit. A road has been built to the Ruth open pit where only diamond-drilling has been carried out so far. The Lucy open pit ore is trucked in 50-ton Euclid trucks to the Sir James plant where it is crushed and then transported by rail to the ore preparation and sinter plant in Wawa. Operations progressed from l January to 31 December 1968. Some 37 diamond-drillholes totalling 6,064 feet were completed from surface. Added equipment consisted of two panel trucks %-ton capacity. A total of 633,127 tons of ore was broken and trucked to the Sir James plant.

Goudrean Pyrite The property consists of 16 claims, located in Township 27, Range 26, in the Sault Ste. Marie mining division and includes the Rand No. l and Bear "A" and "C" groups of claims. There was no operation at the property in 1968. The total ore production from the George W. MacLeod, Ruth and Lucy mines was 3,194,416 net tons. The siderite iron ore is concentrated, sintered and screened before shipment to the steel plants. Most of the final product is shipped by rail and water to the Corporation's plants at Sault Ste. Marie and Port Colborne. The sintering plant of the Division, located at Wawa, operated a total of 294 days during 1968, producing 601,851 net tons of sinter. Added equipment in 1968 included a sinter breaker; a conveyor motor, electric; a tractor, 225 h.p.; pellets and sinter machine flues, steel. 40 Volume 78

The blast furnaces treated a total of 3,283,490 net tons of ore at a daily average of 8,971 tons and produced 2,072,078 net tons of pig iron.

CANADIAN FURNACE DIVISION The Canadian Furnace Division, comprising a blast furnace and the ancillary equipment necessary to produce pig iron, is located at Port Colborne. This division produces malleable, foundry, silvery and modular pig iron in the various ranges requested by the foundry industry. The principal market is in Southern Ontario with some shipments to Quebec, the Maritimes, Manitoba and the U.S.A. The company's opera tion, as a supplier, is vulnerable to conditions affecting its customers and is being adversely affected by the increasing import of foreign pig iron. The straight ore burden, as compared to beneficiated material, averaged approximately 53 percent of the total. Auxiliary fuel, in the form of injected natural gas, was used to reduce coke consumption. Company Annual Report The following is taken from the corporation annual report for the year ending 31 December 1968.

Sales Shipments of steel products increased 7 percent over 1967 to 1.6 million tons but the propprtion of Canadian consumption supplied by Algoma declined. Off-shore shipments were negligible and exports of steel products were higher principally because of strike hedge buying by customers in the United States early in the year. The tonnage of iron shipped rose 14 percent to 246 thousand tons as a result of an order from a customer in the United States which is not likely to be repeated. Sales of Algoma sinter were entirely to customers in the United States and the tonnage declined 9 percent to 163 thousand tons. The average price realized at Sault Ste. Marie on sales of steel products was S126.98 compared to 5124.82 in 1967. There were no price increases during the year and the higher realization resulted from the sale of a larger proportion of more highly finished products. The order backlog for steel products at the end of 1968 was at about the same level as at the end of 1967. High chrome content rails produced by Algoma which resist wear and cracking are receiving increasing attention and Canadian railroads have installed trial sections of this type of rail. Grinding balls with a higher chrome content are being marketed in sizes up to and including 11/2 inches in diameter and these have been well received in the trade because of their extra durability. The range of sizes of this type of grinding ball will be increased to include balls 2 inches in diameter. Several submissions were made to the Department of National Revenue with respect to the dumping of steel into Canada by off-shore producers. This continues to be a serious problem and it is too early to be able to appraise the effect of anti-dumping legislation enacted in December. 41 Annual Report for 1968

Operations Continued emphasis was placed on the use of captive ores in the blast furnaces and almost 87 percent of the total ore smelted was from mines owned or leased by Algoma. A higher tonnage of iron pellets used in the blast furnaces resulted in production of a record 2.1 million tons of iron at the Steelworks. The blast furnace at the Canadian Furnace Division only operated about two thirds of the year. At the Algoma Ore Division 2.3 million tons of ore were mined from the George W. MacLeod underground mine and 560 thousand tons from the new Ruth and Lucy open pit mine. The loading and moving of ore by front-end loaders rather than scrapers has been instituted in the underground mine and has improved handling efficiency. Larger ignition furnaces installed on two sintering machines improved their performance and the new large sintering machine continued to operate very satisfactorily both as to output and quality of product. Metallurgical research continued on methods of processing iron ore from reserves at the Lake St. Joseph, Nordarm and other properties and on methods of improving the quality of Algoma sinter. Tests conducted indicated that it may be feasible to reduce the quantity of metallics lost in finely ground material discarded at the ore treatment plant at Wawa.

Improvements, Additions and Alterations In December a three year option agreement was entered into with Little Long Lac Gold Mines Limited involving approximately 1,500 acres of property near Geraldton, Ontario which contains an extensive hematite-magnetite iron formation. This property is adjacent to the Nordarm property which was acquired in 1966 and is in the same area as the Can-Fer property which was leased in 1965. Algoma has the right under this agreement to enter into a long term renewable lease at reasonable royalty rates. Exploration and metallurgical research is underway to establish the potential of the property.

BETHLEHEM CHILE IRON MINES COMPANY (Marmoraton Mining Company Limited Division) Marmoraton Mining Company Limited Division is a wholly owned subsidiary of Bethlehem Chile Iron Mines Company formerly Bethlehem Steel Corporation. The officers were: E. P. Leach, president and director; H. Olsen, manager, Marmoraton Mining Company Limited Division. The head office and mine offices are at Marmora. The company owns an iron property in Marmora and Rawdon townships, County of Hastings, a short distance east of Marmora. Mining and milling continued throughout 1968. The company maintained an average daily production of 1,750 tons of iron pellets in spite of the necessary job of moving the 54-inch gyratory crusher from under the headframe of the inclined hoistway to a new position, so that trucks are able to dump into it. A stockpile of primary crushed ore had been built up to last the three-month period it took to build and move the crusher. In addition, another three and one-half million tons of waste capping was removed to keep up with the ten year pit expansion program, started five years ago. Since doing away with the ore hoist, the mine has acquired eight 55-ton K.W. Dart trucks and two 65-ton trucks of the same make. The shovels include two 6-yard and one 11-yard Marion electric, and a 5-yard Caterpillar diesel front-end loader. 42 Volume 78

The blast furnaces treated 2,695,740 net tons of ore, averaging 7,386 tons per operating day, to produce 1,825,984 net tons of pig iron.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. During 1968, further progress was made in the program, for air and water pollution control, primarily in the control of effluents from the hot mill, foundry and finishing departments. A feasibility study of a deep well for disposal of waste pickle liquor and other liquid waste was completed. A test well, over 3,000 ft. deep is scheduled for completion in 1969. During 1968 extensive pilot tests were run of a high rate filtration system for removing oil and mill scale from hot mill cooling waters. These tests were successful and plans are in preparation for a full- sized unit which will handle all the water from the hot mill. The company has completed and is operating a pilot unit for testing continuous oil removal from other rolling mill solutions. The company engineers are working on new and better methods of air and water pollution control and are cooperating very closely with the Air Pollution Control Service of the Ontario Department of Health and the Ontario Water Resources Commission on all anti-pollution projects. The Sherman mine near Temagami in northern Ontario was officially dedicated on 5 September, 1968 by the Honourable John P. Robarts, Prime Minister of Ontario. Thirty five car unit trains, haying a capacity of 100 short tons per car now operate daily between the mine and Hamilton, approximately 340 miles, providing a year-round supply of Canadian iron ore. Hie known reserves of iron ore are sufficient for 35 years of operation at a production rate of 1,000,000 gross tons of iron ore pellets annually. As a result of the completion of the expansion program in the Wabush mines joint venture, the company's share of pellet production from this source will increase from about 800,000 to 1,000,000 gross tons annually. The combined production received from the two mines, 2,000,000 gross tons, provides approxi mately 85 percent of the current ore needs. The company is studying other Canadian ore deposits and provided conditions and tax structures in the mining industry do not change significantly, further investment in mining can be expected. 44 Volume 78

The additions and improvements to the present research building to add laboratory space and provide accommodation for the development engineering group are now in the final stages of con struction. To complement the electron probe acquired in 1967, a scanning electron microscope was added in 1968. This enables inspection of steel at greatly increased magnification, clarity and without costly and elaborate preparation of samples. This instrument will also facilitate basic and applied research. The construction of a miniature oxygen steelmaking furnace begun in 1967 was finished in 1968 and test work not previously possible without interfering with production is now being conducted. These experiments will help tile company to maintain its position of leadership in oxygen steelmaking technology. Further investigation of the advantages of using gases to stir molten steel resulted in the practical application of this method in the steelmaking operation. Research now being conducted includes: a reduction process for the reclamation of waste oxide material which has progressed to the point of an 80-ton per day pilot operation; a broad program to develop better coatings to improve the storage and pre-paint properties of galvanized steel; a new method of applying different types of metallic coatings to sheet steel now in the final stages of a feasibility study. Employment and Management The average number of employees at the Sherman mine was 301: 238 on surface and 63 in the open pit. Cliffs of Canada Limited were managers with B. H. Boyum in charge. The average number of employees in the blast furnace division was 315: W. M. Rombough was superintendent.

The blast furnace treated 4,467,834 net tons of ore, averaging 12,274 tons per working day, to produce 3,147,017 net tons of pig iron. A significant record tonnage of pig iron production was achieved in the blast furnace division during 1968. The new "E" blast furnace was commissioned in January. It is meeting all the design expectation and is now producing iron at a consistent rate higher than any blast furnace in the western hemisphere. As a partial replacement of coke, injected fuel in the form of natural gas was used in "A, B, D and E" furnaces, oil was used in the "C" furnace and in addition, plans were well advanced for the injection during 1969 of tar in "D" furnace. The "A" furnace was shut down indefinitely coincident with the commissioning of "E" furnace. The "C" furnace was off blast from mid-October until 31 December for re-line, as was "D" furnace from 7 August to 15 September. Both relined furnaces are scheduled to operate at full capacity to meet the sustained demand of the steel market. Important changes noted during the year were the upgrading of the brick and refractory used in the re-line for longer furnace life; the re-building of some stoves to increase the hot blast temperature from 1,600 degrees F to 1,800 degrees, thereby reducing the consumption of coke for each ton of iron produced; the treatment of water from the gas cleaning equipment to meet the Ontario Water Resources' specifications, and the increased use of Canadian pellets in the burden. 47 Annual Report for 1968

The production of over-fluxed sinter, as a partial replacement of stone to improve blast furnace burden, continued at the productive capacity of the sinter plant. During 1968 development of the SL/RN process for converting iron ore directly into steel, bypassing both the coke oven and blast furnace operations, was continued with tests of a preheating-prehardening grate and kiln combination. A wide range of materials was processed through the pilot plant at Hamilton, for several companies investigating the potentialities of the SL/RN process and the SL-Steelmaking process. Further refinement of the sponge iron-electric furnace technique has resulted in the optimum use of furnace and refining practices with close control over undesirable impurities. SL/RN electrics are now being considered for Stelco's Lake Erie development.

Employment and Management The average number of employees at the Griffith mine was 438: 129 in the open pit and 309 on surface. Pickands Mather and Company were the managing agents; F. P. Morawski was manager. The average number of employees in the blast furnace division of the company was 624: J. A. Peart was superintendent of blast furnaces; J. W. Sibakin was manager, Research and Development department.

STEEP ROCK IRON MINES LIMITED T Steep Rock Iron Mines Limited was incorporated in February 1939. Early in 1955 the authorized capitalization was changed to 10,000 shares of preferred stock of S100 par value and 10,666,666 shares of common stock of SI par value; of which no preferred and 8,063,652 common shares have been issued. The directors and officers were: John Paterson, chairman of the board and director; Neil Edmonstone, president and director; Jakob Isbrandtsen, A. L. Rising Jr., John D. Dale, F. H. Logan, G. E.

Development footage in 1968 consisted of 2,368 feet of drifting. Total development footage to 31 December 1968 was as follows: 49,652 feet of drifts; 14,090 feet of crosscuts; 10,872 feet of raises. Some 25 diamond-drillholes, totalling 9,999 feet were completed from underground.

ROBERTS OPEN PIT MINE The dredging of the "G" ore zone was completed in 1961, and is now an open pit operation called the Roberts mine. The property comprises mine claims in Freeborn township, District of Rainy River. Added equipment included the following:— l dozer, 824B 3 Lectra hauls, 100M. Mining operations continued throughout 1968, and milling proceeded from 20 April to 31 December 1968. A total of 1,630,008 tons of ore was mined in the open pit, of which 757,820 tons were milled in 1968 at an average of 4,258 tons daily during the period of operation.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The new pellet plant which came into production in the fall of 1967 is now approaching a consistent full capacity operation. Changes were found necessary to adapt the equipment to achieve the originally planned rate of production. Although earlier anticipations were not completely realized in 1968, shipments totalled 1,300,000 tons which included 1,057,650 tons of pellets. Due to the lower than anticipated volume of pellet production, operating expenditures were higher than anticipated. This will no doubt adjust itself in 1969 when the plant is expected to be producing at full capacity. Discussions in progress with steel companies could lead to a decision to go ahead with the develop ment of the company's Lake St. Joseph property in northwestern Ontario. As reported previously it is estimated that this property's ore reserve is capable of yielding a minimum of 160,000,000 tons of pellets and can sustain an open pit operation, producing up to 5,000,000 tons of pellets annually. Algoma Steel Corporation already holds a substantial interest in the property under the existing joint venture agreement with Steep Rock. While iron ore prices have not been increased since 1961 (in fact the price was reduced by 90|5 in 1962) cost increases, particularly in wage rates, have required increasing pressure for operating innovations and cost restraints. Although this seven year period has also witnessed a major tech nological change in the iron and steel industry involving a requirement of more sophisticated and more costly products, the company has established itself as an important producer of iron ore pellets.

Employment and Management The average number of employees was 461:16 in the open pit and underground and 445 on surface. Neil Edmonstone, president, was in charge. 49 Annual Report for 1968

LEAD AND ZINC In 1968, the production of lead increased by more than 133 percent from 11,058,534 pounds, valued 51,548,195 in 1967 to 24,800,813 pounds valued 53,467,629. The increase in the value of lead production however, was only 124 percent, due to lower prices for this metal. In the 1962-1966 period, Ontario's zinc output averaged 10 percent of Canada's total zinc production; however, in 1967, it increased to 24.2 percent of the Canadian total. In 1968, Ontario's continuing growth in zinc production increased its share in Canada's zinc output to 29.9 percent. In this year, Canada's zinc production increased from 2,222 million pounds in 1967 to 2,319 million pounds in 1968—an increase of 4.3 percent. The expenditure on labour of 53,386,534, was paid to 416 salaried employees, and 511,108,029 to 1,630 wage-earners.

SHERBROOKE METALLURGICAL COMPANY LIMITED Sherbrooke Metallurgical Company Limited was incorporated in May 1959, with an authorized capitalization of 200,000 common shares of no par value, and 3,000 preferred shares of 510 par value; all common shares have been issued. The officers were: H. D. Cams, president; C. R. MacBrayne, vice-president; R. K. Thoman, vice-president and secretary; and W. E. Greene, treasurer. The head office is at P.O. Box 463, La Salle, Illinois 61301, U.S.A.; the plant address is Port Maitland, P.O. Box 220, Dunnville. Except for the month of August operations were continuous during 1968. The company experienced a further severe reduction in the production and sale of sul phuric acid, during the 1968 calendar year, with sales 40 percent lower than in 1967. The decrease in sales is a direct result of additional softening in the fertilizer industry. Production of zinc oxide increased approximately 15 percent, with product quality, in terms of residual sulphur, slightly improved over 1967. The experimental work on cadmium and lead elimination to improve the calcine, and hence the zinc end product, were somewhat successful but limited, due to existing equipment. A minor reduction in the price of sulphur was made in November, but due to the volume of sales this will have little effect on the company's net flow cash position. Additions to equipment consisted of a vertical heavy duty two stage stationary air com pressor, 13.5 x 8 x 7 ins., 600 cfm. A total of 89,320 tons of concentrate was treated at an average of 267 tons daily to produce 75,350 short tons of zinc oxide calcine.

Employment and Management The average number of employees was 64; J. M. Kew was works manager.

ZENMAC METAL MINES LIMITED Zenmac Metal Mines Limited was incorporated in February 1952 with an authorized capitalization of 10,000,000 shares of SI par value, of which 6,415,755 shares have been issued.

Noble, secretary. The head office is at Suite 1010, 360 Bay Street, Toronto l; the mine address is P.O. Box 189, Schreiber. 50 Volume 78

Zenmac's Zenith mine property, comprises 69 claims located in the Pays Plat Lake area, Schreiber district, about 10 miles north of Lake Superior. Mining and milling operations progressed from l January to 31 December 1968. The vertical three-compartment main shaft, collared in claim TB42277, has a depth of 425 feet below the collar. Development footage in 1968 consisted of 302 feet of drifting, 316 feet of crosscutting and 503 feet of raising. Total development footage to 31 December 1968 was as follows: 3,782 feet of drifts; 1,260 feet of crosscuts; 2,273 feet of raises. Some 170 diamond- drillholes, totalling 20,122 feet were completed from underground. Added equipment in 1968 included the following: l pump, duplex, 5 x 3.5 ins. 1 truck—1969, 27.500 G.V.W. 2 pumps (one SRL 3x3 with motor; one SRL 2x2 with motor) l conditioner, Denver 6 x 6 ft. A total of 47,916 tons of ore was hoisted; 47,326 tons were milled at a daily average of 130 tons. Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The Zenith Mine, near Schreiber, Ontario, operated throughout the year at an average rate of 129 tons of ore per day. Shipments were 14,028 tons of zinc concentrate which yielded net smelter returns of 5771,512.33, or S16.50 per ton milled. The price of prime western zinc, on which smelter settlements are based, remained steady throughout the year at 13.5)4 per pound. Mine operating expenses were {743,576.96, or S15.75 per ton before providing for depreciation and pre-production expenses. More than 20,000 feet of exploratory drilling were done during the year but no important new orebodies were discovered. However, recent increases in the price of zinc to 14.5{ a pound are making operations profitable and they may now be expected to continue for several months longer than previously anticipated. With the approaching end of the Zenith Mine operation management is making diligent efforts to locate a mining property where the modern efficient plant and trained staff could be usefully employed.

Employment and Management The average number of employees was 54: 25 underground and 29 on surface. P. S. Broadhurst was general manager.

MAGNESIUM AND CALCIUM Total Canadian output of magnesium and calcium is being mined and processed in Ontario at Haley in Renfrew county by Dominion Magnesium Limited. From 1962 to 1966, Ontario's production of magnesium averaged 17,561,862 pounds accounting for 5.29 percent of the world's output of this metal. In the 1964-1968 period, Ontario's output of magnesium rose from 18,706,020 pounds to 19,856,937 pounds. At the same time, the value of magnesium, which in 1964 amounted to 55,587,909, increased to 55,653,243 in 1967 and to 56,181,992 in 1968. The calcium produced by Dominion Magnesium has increased by 238.6 percent from 138,357 pounds in 1964 to 468,512 pounds in 1968. This increase in calcium production reached its all time high of 543,692 pounds in 1967. However, in 1968, calcium output decreased by 14.38 percent from 5535,509 in 1967 to 5450,946 in 1968. The company paid 5464,176 to 73 salaried employees, up 5.98 yo from 1967; 51,750,422 to 399 wage-earners, an increase of 10.45 "/0 from 1967. 51 Annual Report for 1968

DOMINION MAGNESIUM LIMITED Dominion Magnesium Limited was incorporated in February 1941, with an authorized capitalization of 500,000 shares of no par value, of which 476,270 shares have been issued. The directors and officers were: H. J. Fraser, president and director; John Thomson, vice- president, general manager and director; C. P. Keeley, L. M. Pidgeon, F. H. Jowsey, G. T. N. Woodrooffe, J. R. Smith and J. M. Mortimer, directors; H. B. Clearihue, secretary-treasurer. The head office is at 20th Floor, 7 King Street East, Toronto 1. The plant address is Haley. Dominion Magnesium Limited holds exclusive patent rights to the Pidgeon magnesium production process. The company's quarry and plant about 3 miles from Haley, comprising 403 acres is in concessions V and VI, Ross township, Renfrew county. A 21 percent magnesium dolomite is mined in two quarries in the plant area, at the rate of about 300 tons daily, as the source of both magnesium and calcium. Only the coarse clean rock, screened ahead of the primary crusher, is used in the magnesium-calcium process. The finer materials are further crushed, dried, and screened to produce special concrete aggregate, flux for the glass industries, and the fines for asphalt and other fillers. Approximately 70 percent of magnesium production was exported, chiefly to the United Kingdom, the United States, Germany and France. Normally the high U.S. tariff on mag nesium prohibits sales to the United States, but export this year was possible under Canada- United States defence-sharing arrangements. A large part of the Canadian market for magnesium is in the production of aluminum alloys. However, the production of extrusions at the plant at Haley increased significantly to over a million pounds in 1968. In addition, the use of magnesium alloy for die-cast components for such equipment as snow cruisers, chain saws, etc. is increasing. Calcium, which is used as a reducing agent for the reduction of uranium and zirconium and for the production of calcium hydride, was produced chiefly for export. The production of small quantities of titanium, zirconium, thorium, barium, and strontium was continued. Aerometal Products and Design, a wholly-owned subsidiary, operates a magnesium fabricat ing plant at Toronto. Major construction in 1968 included two ferrosilicon bins, one 66-ton, the other 128-ton capacity, located in the briquette building. Production of metals for 1967 and 1968 was as follows:

Metal 1967 1968 Calcium crowns Ib 576,614 645,235 Magnesium crowns Ib 19,963,427 22,285,948 Thorium Ib 1,247 1,223 Titanium Ib 19,021 4,722 Barium Ib 1,705 10,219 Strontium Ib 226 733 Zirconium Ib 3,682 4,790

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. All furnace capacity was in operation during the year. The company also produced and shipped 9,689 Ibs. of magnesium zirconium master alloy, 1,789 Ibs. of barium and 82 Ibs. of strontium. The extrusion plant shipped 1,038,548 Ibs. of magnesium alloy extrusions compared to 897,586 Ibs. in 1967. The main items included in capital expenditure were the installation of ferrosilicon storage bins, installation of coolers and bagger for sized residue products, kiln stack gas oxygen analyser, yard lift tracks and mobile ramps at Haley. This is the beginning of a major programme to improve and 52 Volume 78 expand the facility in order to reduce maintenance costs and downtime, reduce costs of raw materials and metal handling, and increase covered storage area for metal products. Aerometals Limited sales for the year showed a 52 percent increase over last year's sales. The products that largely contributed to this increase were magnesium dockboards and the recently developed magnesium bucket for handling concrete. The high cost of ferrosilicon from the Beauharnqis smelter used as a reducing agent in the form of ferrosilicon was due to operational difficulties which resulted in excessive maintenance costs and downtime. In conjunction with Chromium Mining and Smelting Corporation Limited, who operate the smelter under lease, a major facility improvement programme was initiated in October and will be completed in 1969. The company's research activities were mainly concerned with product improvement, die casting alloys and process efficiency. Tests on machine removal of residue from retorts have been discontinued in favour of pneumatic removal. Tests on pneumatic transporting of residue are sufficiently encourag ing to warrant continuing investigations. The present market demand for magnesium is strong and should continue throughout 1969. Calcium sales increased toward the year end and delivery demands for the first quarter of 1969 indicate a good sales volume for the whole year.

Employment and Management The average number of employees at the quarry and plant was 385; D. J. McPhail was plant manager.

METALLURGICAL COMPANIES

GEO-MET REACTORS LIMITED AND MASTERLOY PRODUCTS LIMITED Geo-Met Reactors Limited and Masterloy Products Limited are two associated com panies, under the same management. The Masterloy plant is located five miles south of Ottawa, just east of Highway 31. Further research work was continued and the production of high cost ferro-alloys. Production has consisted mainly of columbium and molybdenum alloys, although some work has been done on others such as tungsten, vanadium, manganese, titanium, chromium and nickel-columbium. Employment and Management The average number of employees was six; M. C. Campbell was plant manager.

FERROX IRON LIMITED AND FERRO-MAGNETICS LIMITED Ferrox Iron Limited and Ferro-Magnetics Limited, both subsidiaries of Magnetics International Limited, formerly Quebec Smelting and Refining Limited, are located at Prescott. Ferrox Iron Limited produces four tons of ferrites per day and twenty tons per day of super-concentrated iron oxide of 99.8 percent purity. Ferro-Magnetics Limited if a research and process development company and was established to develop commercial applications for the Jones high-intensity wet magnetic separator. Employment and Management The average number of employees at both operations was 35. W. J. D. Stone was managing director, J. D. Nye was vice-president and plant manager. 53 Annual Report for 1968 NICKEL - COPPER Canada's average nickel output from 1962 to 1966 represented 55.5 percent of total world nickel production. The Canadian nickel industry increased its production from 497,294,289 pounds in 1967 to 528,716,000 pounds in 1968. Canada's position relative to the world nickel industry, however, declined slightly from 51.6 to 47.9 percent. This decline of Canada's world position was the result of an expansion of nickel production in other areas of the world. During the 1962-1966 period, Ontario's nickel output averaged 71.5 percent of Canada's total nickel production. In 1968, Ontario increased its nickel production to 407,494,000 pounds from 380,117,521 pounds in 1967—an increase of 7.2 percent. Since the commencement of nickel mining in Ontario to December 31, 1968, the value of Ontario's nickel production totalled 55,863,729,356. In the course of the last five years from 1964 to 1968, the value of nickel production rose by approximately 51 percent. The production during this period rose by 25.7 percent, or from 324,187,190 pounds to 407,493,447 pounds. The 1968 increase in the value of nickel per ton as compared to the value of nickel per ton in 1964, is due to changes in product mix and product improvement as well as to the substantial increase in the price of nickel in the last four years. In 1968, the production of copper from the nickel-copper mines totalled 354,985,310 pounds valued at 5169,486,503. In addition to the significant production of nickel and copper these mines also accounted for the Province's entire production of platinum metals, selenium and tellurium. Since 1966, Ontario increasingly produced more of Canada's total copper output. In 1968, the total production of copper from all sources (zinc-copper-lead, nickel-copper, and copper-gold mines) in Ontario increased by 5.24 percent to 581,236,227 pounds from 552,291,827 pounds produced in 1967. The value of this production increased 6.3 percent or to 5278,313,194 in 1968, from 5261,814,899 in 1967. Ontario's predominantly copper mines experienced a 13.8 percent decrease in copper production, from 39,769,454 pounds in 1967 to 34,275,755 pounds in 1968. The value of production decreased 12.9 percent from 518,918,330 in 1967 to 516,486,638 in 1968. In addition to the copper mined by the predominantly copper producing mines, about 2 million pounds of copper, valued at 5990,482, was also produced by the silver-cobalt and gold mines. However, the major sources of copper in Ontario were the nickel-copper mines and zinc-copper-lead mines. In 1968, the nickel-copper mining, smelting and refining industry in Ontario paid 541,549,079 to 4,210 salaried employees and 5152,559,677 to 20,805 wage-earners.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. Production The mine operated throughout the year at an average daily rate of 569 tons. There were 18,609 tons of concentrate produced with a recoverable metal content of 3,133,094 pounds of nickel, 1,732,535 pounds of copper, 850 ounces of platinum and 5,777 ounces of palladium. Metal production was about 20 percent below that for the preceding year due to lower grade of ore mined and slightly lower tonnage treated. The concentrates were sold to The International Nickel Company of Canada Limited at Sudbury, Ontario. Milling Performance figures are tabulated below with comparative data for the four preceding years: 1968 1967 1966 1965 1964 Milled ton 207,417 214,536 211,228 184,364 192,874 Heads, Nickel percent 1.05 1.17 1.28 1.36 1.22 Copper percent 0.53 0.58 0.62 0.64 0.57 Tails, Nickel percent 0.22 0.21 0.22 0.22 0.20 Copper percent 0.05 0.06 0.07 0.06 0.06 Concentrates, Nickel percent 0.47 10.25 10.64 11.15 10.74 Copper percent 5.33 5.55 5.52 5.54 5.53 Recovery, Nickel percent 80.8 83.5 84.8 85.4 85.1 Copper percent 90.7 90.8 90.3 91.8 89.9

Cost A reduction in manpower with anticipated comparative reduction in costs is being sought through the adoption of sub-level, long-hole stoping hi place of cut-and-fill. While a significant reduction in the work force was achieved, the effects were unfortunately nullified through the lower grade of ore treated and the inflationary effects of higher wages and higher cost of materials. The effort to reduce costs continued and will be significantly advanced when Dumbarton Mines hi south-eastern Manitoba comes into production in the middle of the current year, doubling the mill throughput.

Additions to the laboratory equipment acquired during the year include an X-ray diffractometer, X-ray spectrometer, atomic absorption spectrophotometer, permaran surface area meter and a warmen cyclosizer. Employment and Management A. G. Scoble was manager and there were 28 persons employed.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968.

Metal Deliveries 1968 1967 Ib. Ib. Nickel 70,712,000 74,754,000 Copper 39,787,000 32,401,000

During 1968, nickel was again in a short supply position despite the industry's accelerated steps to increase production. The year 1968 opened with a very low inventory of finished nickel which remained low throughout the year, with deliveries closely paralleling production. At both the smelter and the refinery, production was significantly higher than in the previous year, reflecting output from the Strathcona and Longvack South mines. Part of the increase in the smelter production, however, was absorbed in the larger in-process inventories required for the higher rate of production. Deliveries of company-produced nickel were slightly higher in 1968 than in 1967. Total deliveries, however, were less than in 1967 when shipments included Government stockpile nickel sold on a no-profit basis. The reduction in total deliveries in 1968, therefore, did not represent lower earnings to the company. World copper markets were decisively influenced by the shortage resulting from a strike which idled virtually all producers in the United States for more than eight months. Although the strike was settled in March 1968, its after-effects continued to be an important factor in the marketplace beyond the end of the year. In 1968, copper deliveries were the highest in company history. Although an industry-wide slackening developed in the demand for cobalt, Falconbridge's deliveries of this metal increased materially. Demand for precious metals remained firm.

Mines

______1968_____1967 ton ton Ore delivered to treatment plants from company mines 3,208,000 2,210,000

The 45 percent increase in production of ores from company mines reflects the contribution from both Strathcona and Longvack South. The latter mine is a relatively uncomplicated operation and reached full production in October, just 19 months after shaft sinking started and 5 months after the first drift intersected the ore zone. Strathcona mine, on the other hand, is a deep, large and complex ore deposit and has been under development for several years. The first stope ore was produced early in 1968. The rate of progression towards full production at Strathcona was slowed considerably in mid-year by the lack of sufficient miners and extremely high labour turnover. By year-end, employee recruitment 64 Volume 78

and reduced labour turnover resulted in a marked improvement in the rate of advance towards full production. The remainder of the company's mines maintained their production targets throughout the year despite the labour shortage and turnover. At the Lockerby property, mining plant construction is underway. At year-end the steel headframe, hoist house, change house and other surface facilities were essentially completed. Installation of the 12-foot hoist was under way and shaft sinking is expected to commence early in March, 1969. The Onaping mine shaft deepening from the 3050 level progressed satisfactorily and at year-end the shaft bottom was a few feet below the 4025-foot level, with 340 feet remaining to reach its planned depth.

Treatment Plants The Strathcona mill was completed early in 1968 and the first of its two circuits was activated in February with ore from Strathcona mine. The second circuit was brought on stream in August. Ore from both Strathcona and Longvack South mines is fed to this mill, which, late in the year had been tested at a rate of up to 7,000 tons per day. At Falconbridge, the expanded facilities for treating the increased volume of concentrates were successfully placed in service. These comprised mainly the slurry receiving station, the drying and filtering plant, the extended No. 5 blast furnace, and one additional converter.

Iron Ore Concentrator Construction of the iron ore concentrator commenced early in the year and is progressing satis factorily. It is expected that this plant will be ready for initial operation late in 1969, producing a new iron-nickel pellet for international markets.

More than half of the capital expenditure during the year was for the new iron ore concentrator. The remainder was required to complete the expansion of facilities referred to under Mines and Treatment Plants.

Assessment of the company's ore reserves within the Sudbury district resulted in a substantial increase over those at the end of the previous year, to a total of 91,638,000 tons, the highest ore reserves in the company's history. In the determination of the reserves, it should be pointed out that certain promising areas still being investigated were not taken into account. The addition of significant tonnages to proven reserves of lower grade ores from Longvack South mine and lesser amounts from other mines has resulted in an increased tonnage in this category. A slight drop in metal content is indicated. In making the assessment of the company's reserves, new tonnages were calculated from the results of a continuous underground exploration program of several years duration in the two-forty area located between North mine and Strathcona mine. This new tonnage, coupled with significant tonnages outlined by diamond-drilling at North mine, is primarily responsible for a substantial 65 Annual Report for 1968 increase in probable reserves. The effect of these additions, plus lesser amounts in other areas, increased the company's probable reserves by 15,988,600 tons to 35,353,800 tons with a combined metal content of 682,521 tons.

Research and Development A number of important milestones were passed in 1968, marking satisfactory completion of three major programs: the successful demonstration, in an enlarged pilot plant, of a new process for treat ment of lateritic nickel ore in the Dominican Republic; commercial scale operation of a pilot unit at the refinery employing a new process that had been under development for several years; and the piloting of the composite parts of a process for the treatment of large tonnages of nickeliferous pyrrhotite to produce iron-nickel pellets and high-strength SO2 gas for sulphur recovery. In relation to the last-mentioned development, research and development work continued towards improving the separation in milling operations, of copper-nickel concentrates for smelting from a dean nickeliferous pyrrhotite concentrate. The latter material will provide the feed for the new iron ore concentrator. In the smelter, a program for improved metallurgy, improving working conditions and reducing SOa pollution will take up a major part of the research and development effort at Falconbridge in the months ahead.

Employment and Management The Company employed in Ontario in 1968, excluding employees of contractors (totalling 251) doing work for the company, a total of 4,023 employees; 2,498 at the mines, 1,670 underground and 828 on surface, including the concentrators; 1,419 in the smelter and iron ore recovery plants; 106 in two research plants. G. A. Allen was manager of the nickel division; R. R. Holmes was general superintendent, Falconbridge area; W. W. Westaway was general superintendent, Onaping area.

1. ROY GORDON RESEARCH LABORATORY Nickel producers, like other metal producers, are becoming increasingly dependent on lower-grade ore deposits. Because of this, research in extractive metallurgy leading to the development of more efficient processes for the economical recovery of nickel from sulphide and lateritic ores has taken on added importance. The J. Roy Gordon Research Laboratory's principal function is to continue the development of fundamental information that will lead to new and improved process and production methods. In addition, scientists at the laboratory are directing their efforts towards development of new forms of nickel and associated elements. Extensive work is being conducted in the areas of hydrometallurgy, pyrometallurgy and vapometallurgy, and on mineralogical and geological research. The opening of Research Station No. 3 at Port Colborne at the end of 1967 completed the establishment at this location of pyrometallurgical, hydrometallurgical and vapometallurgical pilot facilities for developing extraction and refining processes for both sulphide and oxide ores of nickel. As a direct result of International Nickel's research programs, the company announced on 6 August its decision to build an 585,000,000 refinery at Copper Cliff to produce high purity nickel pellets and powders by the company's new process employing new techniques in the three basic areas of chemical metallurgy namely pyro, vapo and hydrometallurgy.

Employment and Management The average number of scientists, technicians and administrative personnel employed was 67. Dr. Charles E. O'Neill was director.

The imbalance between supply and demand continued throughout 1968 and is persisting. It is necessitating the continuation by the company of worldwide distribution of its nickel on an equitable allotment basis patterned on historical deliveries. In 1969, as the nickel industry's production rises, consumption can be expected to rise accordingly. But, barring major changes in the free world economy, nickel is likely to remain in short supply. The shortage is not expected to have important adverse effects on the long-term growth of nickel consumption.

Nickel Prices On 27 December, the company increased the price of its nickel products because of very sig nificant increased costs it had experienced and as a necessity for carrying forward its large expansion program. The company's price for regular electrolytic nickel became SI.03 (U.S.) per pound, an increase of 9jf per pound. For Canadian consumers the new price became Sl.ll 1/^ (Can.). The price in the United Kingdom for electrolytic nickel, and for refined nickel pellets produced at the company's Clydach, Wales, refinery, became f986 per long ton. Corresponding increases for other nickel products were also put into effect.

Copper After similar action by most other Canadian producers, the company on 10 January, 1969 in creased the price of its "ORC" copper sold in Canada to 48 V^ (Can.) per pound. The price had been Sif* (Can.) for the first half of 1968, falling on 3 July, 1968 to 45jf per pound. On 3 June, the pricing of the company's copper sold in European markets was put on the basis of the London Metal Exchange spot wirebar asked quotation, instead of the LME 3-month sellers' quotation. Similar action was taken by Zambian and Chilean, and other Canadian copper producers. The price at which the company's copper was sold in overseas markets during the year ranged from 45)if (U.S.) per pound to 74ff (U.S.) per pound. The company sold none of its copper in the United States.

Platinum-Group Metals Industrial demand for most platinum-group metals remained strong during 1968. Platinum continued in tight supply despite some further increases in free world production. The January 1968 platinum average published price of SI 11.50 (U.S.) per troy ounce remained unchanged until it increased to SI 22.50 on l July. The average published price for palladium in the United States in creased from S38 per troy ounce to S46 during 1968; rhodium, ruthenium, and iridum prices remained unchanged during the year at S247.50, S57.50 and S187.50 per troy ounce, respectively. GoM As a result of the two-price system which came into effect in March, the company received in creased prices for its gold. The market price on 19 March was S39.50 (U.S.) per troy ounce; it increased to a high of S42.65 on 20 May, and on 31 December, it was S42.05. Silver The New York price for refined silver, which was S2.10 per troy ounce as 1968 began, reached an all-time high of S2.565 on 12 June and at year end was S 1.90.

Development of New Mines In the Sudbury district, shaft-sinking, underground development and construction of surface facilities were pushed ahead at five new mines. Two of these—the Little Stobie and Kirkwood mines— are expected to start producing in 1969. Production at the Coleman mine will be initiated in early 1970, while the Copper Cliff North mine will be in full production in that year. Initial production from the fifth new mine—Copper Cliff South—is scheduled for 1971. In April, the company announced its decision to develop an important new mine and supporting facilities at Shebandowan, at a cost of over 530,000,000. The production shaft will be sunk to a depth of 2,375 feet on the south shoreline of Lower Lake Shebandowan, and a concentrator will be built about a quarter mile from the mine's headframe. Production is scheduled for 1972, at 2,900 tons of ore per day.

Environmental Control There is increasing worldwide concern with pollution of the environment and during the year the company's operations in the Sudbury district were subjected to criticism on this score. Because of their size, these operations present difficult environmental control problems. During the year much work was done to further control or eliminate the discharge of various pollutants into the air and water of the area. Progress was substantial and promises to be more so in the future. 83 Annual Report for 1968

The company's continuing program of growing grass on the tailings areas—some 500 acres are now under grass—and thus controlling dust, attracted considerable favorable attention during the year from other mining companies, the press in Canada and abroad, and government officials. Indicative of the progress in conserving water is the fact that despite the increased water need as a result of heavy expansion, the company in the Sudbury area is drawing the same amount of water as in 1964. This progress has been accomplished by the increased use of water, as at the new Frood Stobie mill which, while requiring 11,500,000 gallons a day, draws and re-cycles its water from the general tailings area. This results in conserving more water than is consumed by the entire population of 85,000 of the City of Sudbury. Clarification and neutralization facilities are now being extended to all mines to ensure that water discharged into natural water courses will not contaminate them. To deal with the problem of sulphur dioxide emitted from the Copper Cliff smelter, the company announced in February 1969 that it will erect a l,250-foot chimney to replace the existing chimneys, two of 500 feet and one of 350 feet. The new chimney will be the highest in the world, about the same height as the Empire State Building, and will assure that the air in the Sudbury district will be cleaner than in any other industrial urban community in Ontario. This stack will always provide important advantages, but additionally the company is continuing its studies and research aimed at more extensive recovery of sulphur from smelter gases and process changes which will reduce the generation of such gases. Additional dust collection equipment will also be installed and, along with similar equipment installed at the Coniston smelter m 1968, will keep paniculate emission of pollutants to a very minor level. The cost of the chimney and the related dust collection equipment will be about 513,000,000. Employment The International Nickel Company of Canada Limited employed for its Ontario opera tions, excluding some 1,129 employees of contractors doing work for the company, a total average of 20,813 employees.

Pilot plant research on improved metallurgy is continuing with the objective of better recovery at the concentrator and the recovery of several additional products, such as pyrite and tin. The cyanide 89 Annual Report for 1968 process for recovering silver from the pyrite and the tailings is also under study. Preliminary studies have begun to develop the underground mine to supplement the open pit production. Substantial progress on a comprehensive study of factors affecting a decision to build the com pany's own smelters in Ontario was made during the year, with particular emphasis on zinc and on determining the most desirable location to be competitive in world markets. Initially, because there is no available smelting capacity in Canada, zinc concentrates have been sold by Texas Gulf to smelters in the United States, Europe and Japan. A copper smelter is also under study. In the mean time, copper concentrates continue to be shipped for smelting and refining to Noranda and Montreal East. The resulting copper metal and silver are returned to the company for sale. Lead concentrates containing much of the silver are shipped from Canada for smelting and sale. Principal products of the metals division continued to be in strong demand in 1968. Silver prices have dropped back from the high levels of more than 52 an ounce which prevailed during much of 1968, but there were increases in other metal prices in 1969. Copper prices in the United States advanced to 44 cents a pound from 42 cents and the price of prime western zinc rose to 14 cents from 13Y2 cents. Free world production and shipments of copper, lead and zinc increased in 1968. Free world production of refined copper amounted to 5.91 million short tons, compared to 5.27 million tons in 1967 when production was limited by protracted strikes in the industry. Free world consumption of refined copper in 1968 reached an estimated 5.58 million short tons, an increase of 4 percent. Free world refined zinc production in 1968 was 4.10 million short tons, compared to 3.64 million tons in the preceding year. Consumption of refined zinc increased to 4.17 million tons in 1968 from 3.72 million tons in 1967. Free world production of refined lead rose to 2.98 million tons in 1968 from 2.75 million tons in 1967. Free world refined lead consumption was 2.92 million tons in 1968 against 2.74 million tons in 1967. Employment and Management The average number of employees was 638: 110 in the open pit and 528 on surface. F. R. Jones was vice-president in charge of production.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968.

Production and Milling Milling was carried out continuously through the year at maximum capacity, except for down time required to make changes and install new equipment in the milling plant. Operating time was 96.5 percent of total hours for the year. Daily treatment rate averaged 1,837.0 tons per day with the rate climbing to about 2,100 tons per day for the last two months. All mill feed was supplied from underground operations, and about 59,500 tons of mine production was stockpiled on surface. Millheads were 1.26 percent copper and 2.82 percent zinc for the first six months and climbed to 1.48 percent copper and 3.93 percent zinc for the last six months. Copper recovery and concentrate grade were off from previous years, but zinc recovery increased substantially. Major changes were made in the mill during the year as well as in the crushing plant. A 5 Vi foot Symons standard cone crusher was installed in June and this allowed three stage crushing and in creased crushing capacity. The grinding section was completely rebuilt and two 12 x 14 foot ball mills replaced four small ball mills. This change provided grinding capacity of about 2,700 tons per day at 75 percent minus 325 mesh. Major circuit changes were made in the flotation section, and additional flotation cells will be installed in 1969, plus additional pumps and thickening capacity, to provide capacity equal to the grinding circuit.

Mining and milling operations continued throughout the year. The three compartment, vertical No. l shaft, located on claim SSM35137 has a depth of 1,251 feet below collar. Development footage completed in 1968 consisted of 1,072 feet of drifting, 488 feet of crosscutting and 924 feet of raising. Total development footage to 31 December 1968 con sisted of 12,330 feet of drifts; 2,655 feet of crosscuts; 3,736 feet of raises. Some 112 diamond- drillholes, totalling 23,206 feet were completed from underground and 26 holes totalling 13,335 feet were completed from surface. Major construction in 1968 included a pumphouse (fire buster) 14 x 12 feet and a core storage rack 22 x 12 feet. Added equipment was as follows: l grader, 440H l slusher, three drum 25 hp l slusher, two drum 30 hp l automobile, 1969 A total of 157,408 tons of ore was hoisted; 157,787 tons were milled at a daily average of 432 tons. Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The average price received in smelter shipments was 50.4ff per pound, compared with 54.Iff for the eight months of 1968. Since the year end a more favourable basis for pricing has been arranged with Noranda, and the major portion of Tribag's copper is now settled on the London Metal Exchange average price. In recent months this has averaged approximately 64^, or 15 Vi fi per pound above the domestic price. Copper production for the year was 5,562,840 pounds after milling of 157,787 tons grading 1.82 percent copper. The mill operated satisfactorily throughout the year with recovery averaging 97.9 percent and with a concentrate grade of 31.64 percent copper. Shrinkage stoping provided the major portion of mill feed, but by year end the blast hole stope was making a substantial contribution. Some difficulty was encountered with fragmentation in the initial blasts but the problems of ore handling have been solved and the blast hole stope is producing at a satisfactory rate. Operating costs were higher due primarily to the large increase in broken reserves required in shrinkage stoping and the development required for the blast hole stope. At year end broken reserves were 90,646 tons. COMPARATIVE MINE OPERATING COSTS

The increase in unit cost is due primarily to the large increase in broken reserves necessary for shrinkage stoping and the inventory of long-hole drilling in the blast hole stope. On the cost per ton broken basis, costs in 1968 are 56.65 per ton broken compared to 58.20 per ton broken in 1967.

On Reserves The underground diamond-drill program was directed primarily toward outlining known ore zones and to exploring of the breccia below the 1200 level. Underground drilling and mining were successful in locating ore extensions in some areas. After milling 157,787 tons at 1.82 percent copper 98 Volume 78 during the year, ore reserves were 689,522 tons at 1.67 percent copper. This does not include any provision for ore from the west breccia, pending examination of the occurrences from underground.

Exploration Exploration activities, suspended during the preproduction and early production stages, were resumed during the last quarter of the year. Diamond-drilling in the west breccia pipe, 2,500 feet southeast of the Breton breccia, was successful in locating two new ore zones at depths of 75 feet and 600 feet below surface. An adit has been driven to develop the upper zone and some ore from this will be milled during July. Exploratory drilling of the south and east breccias is scheduled during the coming months, in addition to a continuing program in the west breccia. Emphasis will also be placed upon surface mapping and prospecting for new breccia pipes similar to those already known.

Employment and Management The average number of employees was 136; 62 underground and 74 on surface. A. Mitchell was mine manager.

WILLECHO MINES LIMITED Willecho Mines Limited was incorporated in February 1964 with an authorized capitaliza tion of 3,000,000 shares of SI par value, all shares have been issued. The company was formed as a jointly-owned operating company of Lun-Echo Gold Mines Limited and Willroy Mines Limited to operate the former Lun-Echo base metal property. In June 1967 both Willroy Mines Limited and Willecho Mines Limited became associate companies of The Little Long Lac Gold Mines Limited. The directors and officers of Willroy and Willecho are essentially the same and are recorded under Willroy Mines Limited in this report. The head office is at 112 King Street West, Toronto l; the mine address is Manitouwadge. The property comprises SO claims in Mapledoram township, Manitouwadge area, District of Thunder Bay. Mining and milling operations continued throughout 1968. The vertical, three compartment No. l shaft, in claim TB47378 has a depth of 1,361 feet below the collar. Development work in 1968 consisted of 3,756 feet of drifting, 68 feet of crosscutting and 8,360 feet of raising. Total development footage to 31 December 1968 was as follows: 15,056 feet of drifts; 2,511 feet of crosscuts; and 29,694 feet of raises. Some 327 diamond-drillholes totalling 45,252 feet were completed from underground. Major added equipment in 1968 consisted of one pump, 300 gpm. at 552 ft. head for underground sump; one conveying system, 1,900 feet long, 42 inches wide at the 1,000 ft. incline. A total of 346,037 tons of ore was hoisted; 346,444 tons were treated at the Willroy concentrator at an average of 1,039 tons daily.

Company Annual Report The following is taken from the combined Willroy and Willecho annual report for the year ending 31 December 1968.

Production During the year past, the total ore delivered to the Willroy concentrator for processing was increased to a new high of 346,444 tons. Grade was down fractionally to .44 percent copper, 3.43 percent zinc, 0.26 percent lead and 2.15 ounces silver. Due to the delay in completing the conveying system from the new levels, production from below the 1000-foot level amounted to only 21,298 tons. 99 Annual Report for 1968

Ore treated in the Willroy concentrator produced concentrates containing the following metal content. Zinc Ib 18,707,664 Copper Ib 2,523,133 Lead Ib 1,248,894 Silver oz 402,680 Gold oz 526 These concentrates, with a gross value of 34,323,102 produced a net smelter return of 52,871,076 or 58.29 per ton of ore milled. Overall unit operating costs were higher than 1967 figures, the increase being due to the resumption of the regular Cost Element Allowance for the use of the Willroy mill. Administration and general and the combination of development and mining both show a slight reduction. Comparison with the previous year is as follows:

Development and Mining In an effort to maintain forecast production tonnages, it was necessary to develop a number of small "D" zone stopes on the upper levels. Pillar recovery was also in progress on the "B" zone. Tonnage obtained from the new stopes on the 1000-foot level proved to be greater than anticipated but with only a slight improvement in grade. The main incline rock excavations were completed in April with levels established at the 1125 feet, 1250 feet and 1350 feet horizons. Level and stope development was discontinued from the commence ment of the conveyor installation in May until August when the system became fully operational. Thereafter, work was resumed on the 1250 and 1350 levels and stopes established to feed directly into the ore handling complex. A conventional transfer arrangement was designed and installed in the conveyor discharge raise to permit selective diversion of ore and waste to the appropriate loading pocket. Tonnage being mined and delivered up the conveyor was on the increase at year end.

Ore Reserves Further drilling carried out from the conveyor incline and from the haulageways on the 1125,1250 and 1350 levels indicate irregularity and a lack of continuity of the zoning below the 1000-foot horizon. As a result, more difficult and higher cost mining can be expected in this section of the mine. The total proven and indicated ore reserves at the end of December to a depth of 1400 feet below collar have been determined at 985,498 tons with a composite grade of 0.54 percent copper, 4.57 percent zinc, 0.18 percent lead and 1.75 ounces of silver.

Employment and Management The operation continued under Willroy management and labour. J. I. Jarvis was mine manager.

WILLROY MINES LIMITED Willroy Mines Limited was incorporated in January 1954; in June 1966 the Norlartic division was added and the authorized capitalization became 6,000,000 shares of no par value of which 4,280,244 shares have been issued.

Added equipment included the following: 2 trucks, 34 ton capacity (one gas; one diesel) l ore sampling plant, complete l scooptram, model St.2A l drill jumbo—3 booms, complete l backfill equipment, underground.

Company Annual Report The following is taken from the combined Willroy and Willecho annual report for the year ending 31 December 1968.

Production The tonnage processed in the concentrator throughout the year was increased appreciably to 531,435 tons or 1,452 tons per calendar day. Of this amount 357,099 tons, or 67 percent were milled for Willecho and Big Nama Creek with the remainder, except for the small tonnage recovered from development and previously broken reserves, once again being obtained from Willroy's main No. 3 zone. The percentages of mill feed from all zones and other sources are shown on the following table.

The grade of the tonnage milled from the Willroy operation averaged 0.96 percent copper, 2.10 percent zinc, 0.08 percent lead and 0.77 ounces of silver. Concentrate production totalled 162 cars made up of 79 cars of copper, 79 cars of zinc and 4 cars of lead. This yielded a gross value of 52,039,327 and a net smelter return of Sl.437,334 or S8.24 per ton milled. 101 Annual Report for 1968

Big Nama Creek Property Underground development of the Big Nama Creek orebody commenced in mid-year after com pleting initial surface installations. These included additional site clearing for and construction of a substation, and the provision for power, compressed air and water services at the entrance to the incline. The rock faces of the previously excavated open cut entrance were secured with screening and rockbolts preliminary to removal of the first round early in July. Development continued for the remainder of the year utilizing a Model St-5A Wagner scooptram for muck removal. Total advance on the —H 0 incline roadway (9 ft. x 15 ft.) during this period was 533 feet in addition to the 891 feet of lateral sub-levels driven through the ore zone. A 61-foot raise from the incline to surface breakthrough was acquired for escapement and ventilation purposes. Prior to the onset of freezing temperatures, a l .750,000 BTU oil fired heating and ventilation system was put into service and a 26 ft. x 48 ft. galvanized domed enclosure was installed over the open cut of the entrance tunnel. Geological data obtained from 580 feet of drifting and diamond-drilling on the top sub-level indicated local constrictions where the zone narrows and the grade drops due to the presence of barren iron formation and pegmatites. As a result of these findings, a surface drilling program consisting of 19 holes totalling 3,701 feet was undertaken late in 1968 to outline the depth picture of the zone in greater detail. Core intersections from this sectional drilling confirmed a number of intermediate intersections which were narrow and of marginal grade. This information necessitated a reappraisal of the whole project. Economics presently indicate mining operations will be carried out to the 300 foot horizon until the ground below this level can be properly evaluated. Reserves at year end to a depth of 300 feet below surface, including the surface pillar, were calculated at 453,039 tons grading 1.01 percent copper, 3.90 percent zinc, 0.03 percent lead and 0.84 ounces silver. A series of batch mill tests were carried out in the Willroy mill on the 10,655 tons of ore recovered from the sub-level development. Composite grade ran 0.87 percent copper, 5.08 percent zinc, 0.11 percent lead and 1.21 ounces silver for a net smelter return of S10.14 per ton treated. Results of these tests indicated compatibility with Willroy and Willecho ores with similar recoveries for comparable

Ore Reserves At 31 December 1968, the total broken, proven and indicated reserves at the Willroy mine above the 16 level (2600 ft. horizon) stood at 261,869 tons. The 1967 reserve figures in the copper zones were reduced for economic reasons but these were partially offset by additional tonnage outlined in the No. 3 and No. 7 zones. At Nama Creek, additional drilling from surface and underground workings disclosed very narrow and low grade sections on the lower part of the zone. Reserve tonnage has therefore been recalculated from the 600 to the 300 foot depth and reduced accordingly. 102 Volume 78

SILVER-COBALT In the 1964-1968 period, Ontario's silver production averaged 10,127,468 ounces, accounting for 32.5 percent of Canada's average silver production of 31,189,584 ounces. In 1967, Ontario's silver output increased to 14,309,391 ounces, representing 39.4 percent of the total amount of silver produced in Canada. By 1968, Ontario's production rose to 21,844,592 ounces, account ing for 48.5 percent of Canada's silver production. In 1968, the mines of the Cobalt-Gowganda area milled 251,359 tons of ore and re-treated an additional 105,730 tons of tailings, from which 5,215 tons of concentrates were shipped to Noranda Mines Limited, 1,836 tons to the Cobalt Refinery Division of Kam-Kotia Mines Limited, and 200 tons to American Smelting and Refining Company. From the total of 7,251 tons of concentrates, 4,342,698 ounces of silver were recovered, valued at S10,044,660. In addition to the Cobalt-Gowganda silver output, the base metal mines produced 15,418,662 ounces, the nickel-copper mines produced 1,754,000 ounces and the gold mines produced 329,232 ounces. During 1967 and 1968 cobalt output in Ontario increased to 2,929,470 and 3,221,000 pounds, accounting for 81.3 and 79.9 percent of cobalt produced in Canada, respectively. Cobalt was produced in only two areas in Ontario: in the Sudbury area, some 96 percent of the entire Ontario cobalt output was derived as a by-product of nickel-copper operations and in the Cobalt-Gowganda area, the remainder was mined in conjunction with silver. The mines of the Cobalt-Gowganda area reported the recovery of 124,592 pounds of cobalt from ores and concentrates shipped to Cobalt Refinery; the refining of nickel-copper ores produced 3,096,433 pounds of cobalt. The total of 3,221,025 pounds of cobalt produced in 1968 shows an increase of 9.95 percent over the 1967 production of 2,929,470 pounds; the value of production increased 16.60 percent from S5,976,044 in 1967 to S6,957,851 in 1968. The silver-cobalt mines of the Cobalt-Gowganda areas paid S693,571 to 104 salaried employees and S2,953,427 to 536 wage-earners. 103 Annual Report for 1968

107 Annual Report for 1968

A total of 885 feet of drifting, 346 feet of crosscutting and 730 feet of raising was com pleted in 1968. Total development footage to 31 December 1968 was as follows: 50,883 feet of drifts; 16,691 feet of crosscuts; 20,274 feet of raises. Some 66 diamond-drillholes, totalling 6,870 feet were drilled from underground. A total of 8,460 tons of ore was hoisted; 21,881 tons were milled along with 15,943 tons custom milled at an average of 113 tons per working day.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The value of metal production during 1968 was just under 5400,000 resulting in a net profit for the year of 513,515. This of course has resulted from mining and milling operations at Cobalt, Ontario. Recently, a further small mill run has been completed, and the mill has been shut down for the time being. The directors are currently reviewing the status of operations at the Cobalt property and a decision will be made as to whether or not the results of underground development warrant the expenditure of further funds hi an endeavour to develop new ore.

Employment and Management The average number of employees was 51: 26 underground and 25 on surface. G. A. Smith was mine manager.

The major part of the exploration and development work was conducted in the following areas.

AREAS SERVED BY NO. 6 SHAFT Flynn System Exploratory work carried out on the 240, 350 and 400-foot levels during the early part of the year did not prove up any significant ore and was discontinued. The known ore in the "19" vein was exhausted by the year end. This relatively small ore shoot has produced an estimated 50,000 ounces of silver since its discovery in 1966. The area to the north is considered worthy of further exploration and work will be done in the coming year.

Castle No. l Shaft Area Better than 50 percent of the lateral exploration and development was concentrated in this area, and was reasonably successful. Combined development and mining operations on the 525 and 650- foot levels provided 25 percent of the year's production from the No. 6 shaft and Castle properties. Exploration work is to be extended southward to embrace the Tonopah mines underground workings, located about 3,500 feet in a south-easterly direction from the No. 6 shaft. The Tonopah mine reported a production of 452,000 ounces of silver in the years 1925-1928, at which time it was closed down. The property was acquired by Castle Trethewey mines some years ago and is part of the Castle mine holdings leased to Siscoe in 1967, under an agreement with Mcintyre Porcupine Mines Limited. A drift directed towards a point beneath the northern part of the Tonopah mine workings was commenced late in the year, on the Siscoe 650-foot level. The heading had about 600 feet to go at year end and is expected to reach the objective about 15 March, 1969. A diamond-drillhole directed to tap the Tonopah 480-foot (bottom level) will be drilled for the purpose of dewatering the workings via their No. 6 shaft pumping system. Following this, an inclined raise to connect the two levels will be driven.

Capitol Shaft Area Development and mining operations conducted on the 1,125,1,200 and 1,275-foot levels through out the year resulted in a fair production from this area. The 1,350 and 1,425-foot levels were de- watered and rehabilitated and some exploration and development work was done during the last half of the year. A 680-foot crosscut was driven on the 1,475-foot level (No. 6 shaft) to beneath the Capitol 1,425 level. An ore pass joining the 1,475, 1,425 and 1,350-foot levels was completed. Ore from the two latter levels will be hoisted to surface via No. 6 shaft.

AREAS NOT SERVED BY NO. 6 SHAFT

Lower Bonsall Exploratory work was carried out intermittently during the first half of the year. Mining operations began in August and a mill run was made in the months of November and December. 5,904 tons were milled for a recovery of 114,527 ounces of silver. 5,704 feet of surface diamond-drilling was done to seek the possible eastward and/or southward extensions of silver bearing veins encountered in the drilling conducted in this area in 1967. One hole cut visible silver at a shallow depth but as a whole the program did not prove up any ore in economic quantity. Present plans are to test an area lying about 1,000 feet to the east in 1969. Underground exploration is continuing at a moderate pace. 119 Annual Report for 1968

Manridge Project During the year, Siscoe Metals entered into an agreement with Manridge Mines Limited to lease the latter's extensive property holdings located in the Township of Milner, and about 12 miles distant from Siscoe. Surface diamond-drilling conducted previously under the direction of Zenmac Metal Mines as well as drilling done by Siscoe Metals in the fall of 1968 indicates a quantity of silver ore of economic value, and fully warrants a program of underground work. A contract to construct a headframe and other plant buildings needed to conduct such a program was let and construction began at year end. Construction of the plant and rehabilitation of the No. 3 or Central shaft is expected to be completed about the 1st of May, 1969, and a drive towards the indicated ore zones will then commence. Some production from this property may be expected in 1969. The ore will be periodically stockpiled and processed in the Siscoe mill.

The increase in the per ton milled unit cost amounts to approximately 24 percent over 1967. Of this, approximately 20 percent or 53.73 per ton is attributable to general wage increases, accelerated exploration and development and lower tonnage milled. The increase in the cost per ounce produced was less at 8 percent. This is due to the greater number of ounces produced in 1968. Employment and Management The average number of employees was 98: 66 underground and 32 on surface. E. A. Pearson was mine manager. 120 Volume 78

CAN-FED RESOURCES CORPORATION (Faraday Mine) Can-Fed Resources Corporation was incorporated in April 1967 with an authorized capitalization of 10,000,000 shares of 30.23 par value, of which 20,000 shares have been issued. The officers of the company were: N. W. Stalheim, president, D. V. Peters, secretary- treasurer. The head office is at 1370 South Third West, Salt Lake City, Utah 84115, U.S.A.; the mine address is Faraday Mine, Bancroft. The property comprises 4,382 acres in Faraday township, County of Hastings. The Faraday mine and mill operated from April 1957 to July 1964, during which time it produced 5,807,693 pounds of uranium oxide. The closure was brought about by lack of markets and not through exhaustion of the ore. An agreement was reached with Federal Resources Corporation which is expected to lead to a resumption of production. Federal is proceeding with a program of underground development designed to increase the presently known ore reserves and has the right to proceed to rehabilitate the mine and mill. If Federal completes this undertaking, it will have earned a 51 percent interest in the project; Faraday will retain 49 percent and in addition, will receive SI,000,000 out of future profits.

Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. The development of nuclear power at an accelerating rate since 1965 has focused world attention on the sources of uranium tp fuel the nuclear reactors of the 1970's and 1980's. It is evident that world demand for uranium in the early seventies will exceed the present capabilities of the mining industry. The need will be met in part by increasing the production capabilities of existing mines and in part from other known orebodies which can be developed. But this will not be enough; a large part 124 Volume 78 of the requirements after 1975 must come from uranium ore deposits not yet discovered. It is clear that an organized, scientific and deep probing search for new orebodies, on a scale unprecedented in the mining industry, is needed. A massive industry response has begun, spurred by the realization that seldom has the private market demand for a mineral been so clearly forecast and seldom has a forecast been so soundly based.

Mine Programs Capital expenditures in 1968 were concentrated on underground projects and equipment, including mine development. The objective has been to examine and improve the principal elements of mining operations at the Denison mine which are, 1. the drilling, breaking and removal of uranium ore from rooms spaced regularly in the inclined orebody 2. the loading and haulage of the broken ore to a conveyor belt network for transportation to crusher and mine shafts 3. the hoisting of ore to surface The program of mine preparedness initiated in 1966 was continued through 1968 to improve the effectiveness of each of the operations in the mining sequence. It includes, 1. re-equipment of crews 2. adaptation of large, mobile haulage and loading machines to Denison operating conditions 3. major modifications of drilling and rock breaking practices 4. installation of a high capacity belt conveyor network in newly developed arteries of the mine 5. installation of a large crusher in the underground transportation network Major development projects continued in 1968. The long underground excavation begun in 1966, to connect Denison workings with the former Can-Met workings was completed on schedule. In addition to providing access to the eastern section of the Denison orebody, it will be a valuable addition to the mine ventilation system. Access to the south-central area of the mine by excavation of an artery was well advanced during the year; completion to the Denison south boundary is expected in 1969. Continuing equipment replacement trials have resulted in the purchase of several large, mobile units for the loading and haulage of ore. For example, new trucks now in underground service have a low-profile design, a capacity of 20 tons and discharge their loads by telescopic action. The plan for equipment replacement has the flexibility to be accelerated as needed. To sum up, 1968 was a year in which key projects were completed and modified mining practices passed through the trial stages and became effective. Additional improvements are expected in 1969.

Other Developments Yttrium oxide concentrate production during the year was less than scheduled because of market oversupply problems experienced by the principal yttrium refining companies. As a result of a review of the sources and costs of chemicals and principal supplies required in large quantities for uranium processing, the company has arranged to acquire a 49 percent interest in Reiss Lime Company of Canada Limited. This company expects to build a plant and dock facilities on the north shore of Lake Huron near Spragge, Ontario to supply industrial lime in part of northern Ontario.

Employment and Management The average number of employees was 860: 489 underground and 371 on surface. M. J. deBastiani was mine manager, John Kostiuk was vice-president and general manager.

Company Annual Report The following pertaining to the uranium operation was taken from the company annual report for the year ending 31 December 1968. The first stage of a long-term program to reactivate certain of the company's uranium properties at Elliot Lake was substantially completed in 1968. This involved rehabilitation of the Old Quirke mine, reactivation and expansion of the Old Quirke mill and development of the New Quirke mine. Operations were transferred from Nordic to the Quirke facilities during the third quarter. The mill is processing production ore from the Old Quirke mine together with development ore and a small but increasing volume of production ore from the New Quirke mine. The second stage of the reactivation of Elliot Lake properties is planned for completion hi 1972. This reactivation program will permit an orderly increase in production capacity required to meet deliveries under contracts which had been signed previously with the United Kingdom Atomic Energy Authority, Ontario Hydro, and eight Japanese electric utilities. Under these contracts additional capacity will need to be brought into production at Elliot Lake during 1972. As the uranium market increases, additional production capacity will be brought on stream. The Nordic mine and mill operated at capacity until vacation shutdown in mid-July when milling operations ceased. The operation of the Old Quirke mine and mill commenced as scheduled on 29 July with the transfer of operations from Nordic to the Quirke site being effected without difficulty, except that a strike which started on 14 August forced the shutdown of afi uranium operations for 29 days. Although the transfer imposed complex mine scheduling problems, the enlarged mill at Old Quirke is now operating at above its rated capacity of 3,700 tons per day. A total of 1,167,000 tons of ore was milled during the year. The average recovered grade, including development and preproduction ore and uranium oxide recoveries when the Nordic mill circuit shut down, was 1.96 pounds of uranium oxide per ton and the average recovery rate was 93.3 percent. The decline in average recovered grade as compared to 1967 was the expected result of the planned mining of fringe areas in the Nordic mine as the orebody was exhausted at presently developed levels and the processing of development ore from the New Quirke mine. This was partly offset by the higher grade Old Quirke ore which was mined at a progressively higher rate in the last half of the year. A total of 2,293,000 pounds of uranium oxide was produced including 96,000 pounds from underground leaching at Nordic and at the Old Quirke mine. Deliveries totalling 2,402,000 pounds of uranium oxide were made under the master contract with Eldorado Nuclear Limited. The shaft at the New Quirke mine was completed in the first quarter of the year and ore and waste passes and ventilation raises are being driven. Ore development was commenced on the 2nd and 3rd levels in the second quarter. Construction of a semi-automatic electric railway for the haulage of ore from the new mine to the Quirke mill was completed in February 1969. Production from this mine will be increased to 2,200 tons per day during 1969 and to 3,200 tons in 1970. A daily mining rate of 5,200 tons, part of which will be milled at another property, is planned for 1971 and in that year production from the New Quirke mine will replace that from the Old Quirke mine, the reserves of which will have been exhausted. Employment and Management The average number of employees at the Nordic mine was 357; 179 underground and 178 on surface. R. T. Sullivan was project manager of the Nordic section. The average number of employees at the Quirke No. l and the New Quirke mine was 503; 264 underground and 239 on surface. G. C. B. Bourne was manager at the Quirke section. E. W. Cheeseman was manager, Rio Algom Uranium Mines; P. E. Young was manager of administration.

The total development footage completed when mining operations were terminated comprised 114,045 feet of drifts, 2,861 feet of crosscuts, and 4,376 feet of raises that were driven between ore sheets; some 46,000 feet of advance in slot raising for production mining and boxhole raising is not included. Uranium recovery during 1968 was restricted to bacterial leaching in the mined-out areas on a three-month cyclical schedule. Washing was carried out on two shifts per day with eight men comprising a washing shift. Some 643,012 tons of mine water was pumped for the recovery of U3O8. Company Annual Report The following is taken from the company annual report for the year ending 31 December 1968. In 1968, electrical utility companies in the United States placed orders for fourteen additional nuclear-electric power plants with a combined generating capacity of 13,000 megawatts. This pace is slower than the pace at which the industry expanded in 1966 and 1967, but, nevertheless, represents an enormous additional investment in nuclear plants. The trend to larger units continued. The average capacity of the fourteen new plants was more than 900 megawatts. Six of the fourteen, with ratings of more than 1,000 megawatts, will be at least as large as the largest steam generating unit now operating in the world. The United States Atomic Energy Commission estimates that by 1980 U.S. nuclear energy capacity will be approximately 150,000 megawatts. The AEC estimates that the total consumption of UsOg through that year, plus an eight year forward reserve, will be approximately 650,000 tons of UaOg or roughly 450,000 tons in excess of the known reserves in the United States today which can be commercially exploited at a price per pound of S10. The ratio of projected demand to known reserves elsewhere in the free world is expected to be in approximately the same range, according to the AEC. The tremendous interest in this relatively new source of power, and the shortage of low cost reserves, is evidenced by the amount of exploratory drilling both under way and anticipated in the immediate future. The AEC estimates that in the next few years an annual average of 25,000,000 feet of drilling for uranium will be carried out in the western United States. It seems very unlikely, in the absence of some extraordinary development, that the price of UaOg will remain at present levels, that is 57.50—58.00 per pound. The company is looking forward with confidence to an increase in price and other improved economic conditions in the industry which will enable it to resume conventional mining of the Elliot Lake uranium deposits. During the year, the company continued to produce UaOg by the bacterial leaching method. All production is sold to a reactor manufacturer at a price in excess of the 55.00 Canadian Government stockpile price. In 1968 the company produced by bacterial leaching uranium oxide with a sales value of 5512,598. A feasibility study by consulting geologists and mining engineers was completed during the year. The study included a reassessment of the Elliot Lake uranium reserves. The company has substantially increased the estimate of reserves of assured and probable uranium-bearing material to approximately 10,000,000 tons grading approximately 1.5 pounds of UsOg per ton, plus possible additional reserves 129 Annual Report for 1968 of considerable magnitude. These reserves do not include the deposits which exist on the near-by properties of North Rock Mines Limited, or which may exist on the relatively unexplored properties the company has acquired from the Stanward Corporation in 1967.

Employment and Management The average number of employees was 46: 13 underground and 33 on surface. B. G. MacDermid was mine manager. YTTRIUM The production of yttrium decreased 34.32 percent in quantity from 172,551 pounds in 1967 to 113,330 pounds in 1968; the value of production decreased 41.29 per cent from 51,594,298 in 1967 to 5936,067 in 1968. Both thorium and yttrium are recovered as by product oxides from the milling of the Elliot Lake uranium ores. The general statistics for yttrium are included under URANIUM.

The company officers were: J. Cochran, president; S. A. Kerr, secretary; F. H. Dickinson, treasurer; T. Oosterhoff, general manager. The head office address is P.O. Box 6138, Montreal 101, Quebec. The mine address is Caledonia. The company has two gypsum properties and a mill in Seneca township, Haldimand county. The old mine, in lot 10, range l west, has been abandoned. Operations at the new mine in lot 8, range 2 west, continued from 2 January to 31 December 1968. The room-and- pillar method of mining is used, which consists of rooms or pockets, leads, and crosscuts, all approximately 21 feet in width by 8.5 feet in height. A ton of gypsum ore in place is equivalent to about 13.7 cubic feet; each foot of advance produces an average of 13.3 tons of gypsum. The total advance in 1968 was 14,729 feet; approximately 10.8 acres were mined out. The tonnage of gypsum mined during 1968 to meet the demands of the board and plaster divisions of the company and the cement industry equalled that of the previous year. Phasing out of the older electrically driven continuous loaders and diesel-electric shuttle car combinations continued. Three diesel-powered scoop loaders, one high pressure hydraulic rotary drill, one front end loader, one tractor and service vehicles were used to meet produc tion requirements using recovery rooms in the room-and-pillar mining system. Plans were finalized to open a new mining panel and to relocate the underground crusher and conveyor system consistent with the foregoing, which would result in a reduction of the ore handling distances for the next few years. During the year a total of 231,972 tons of ore was hoisted; 186,710 tons were milled at an average of 747 tons daily.

INTERNATIONAL MINERALS AND CHEMICAL CORPORATION (CANADA) LIMITED Canadian Flint and Spar Company Limited was incorporated in March 1930. In December 1955, the name was changed to International Minerals and Chemical Corporation (Canada) Limited. The company is wholly owned by International Minerals and Chemical Corporation, Old Orchard Road, Stokie, Illinois, U.S.A. The company officers were: N. C. White, president and director; J. R. Taylor, secretary; J. T. Gibson, treasurer. The head office is at 4 King Street West, Toronto 1. The mine address is Box 309, Havelock. The company owns about 340 acres, in Methuen township, county of Peterborough. The quarry and plant is located at the east end of Blue Mountain, some 25 miles north of Havelock. The Blue Mountain nepheline syenite deposit is some five miles long with an average height of about 350 feet above the surrounding country; the width varies from about one-quarter of a mile at the narrow portion to one mile at the widest part. The ore reserves and the quarry type of mining used do not present too many problems; however, selective mining and mixing of the ores to meet customer specifications is required. The rock is quarried, crushed and ground to a granular sand size, about 30 mesh; at this size minor iron minerals are removed by magnetic separation. Some of the material is then ground further to produce various grades of powder from 200 mesh to micron size. The material is used mainly in the glass industry, in ceramics and as a filler in paints, rubber and plastics. Additional grinding, screening, magnetic separation and dust collection equipment was installed to further increase production, and included the following: 2 rolls crusher sets with two bins 2 separators with two bins 2 screening machines 2 bucket elevators 1 filter dust collector, 10,000 cfm. 2 storage bins, 350-ton capacity. Mining and milling continued throughout 1968. The mill treated 224,000 tons averaging 709 tons daily compared to 151,669 tons in 1967. Employment and Management The average number of employees was 52; 42 in the plant, and 10 in the pit. L. F. McDonnell was area manager.

Production and shipments remained at a high level; increased demand in both the export and domestic markets was experienced over the latter half of the year. Installation of an additional lateral conveyor to the main North-South system was completed in November. Included with this new facility was the fourth loading and crushing station. Phasing out of older haulage units was initiated this year and this course of action will result in the use of larger trucks in underground service. Future transportation and face loading equipment will be large front-end loaders and 35 to 45-ton trucks. The mining pattern of room-and-pillar layout, with faces to a height of 20 feet, continues. Rooms are 50 feet wide and truckways and crosscuts are now 40 feet in width to accommodate the larger face units. The practice of leaving sk feet of salt on the roof for pillar stability remains in effect. Several changes have been made in the milling operations to bring about cleaner separation of product sizes. Development work in 1968 on the 975-foot level consisted of 2,260 feet of drifting, 10,340 feet of crosscutting and 17,620 feet of rooms. Total development footage to 31 December 1968 was as follows: 63,008 feet of drifts; 72,644 feet of crosscuts; 144,774 feet of rooms. Major added equipment in 1968 consisted of a 36-inch conveyor 1,400 feet long, and one 56-inch feeder 68 feet long in 12 West section. A total of 1,821,924 tons of salt was hoisted and milled as compared to 1,656,492 tons in 1967. The mill treated a daily average of 6,695 tons. 138 Volume 78

Production and shipments of rock salt continued at a high rate for most of 1968. Mine production was on a four shift basis for seven days a week during the Great Lakes navigation season. The construction of No. 2 headframe, shaft house, and hoistroom were completed. A fully automatic friction type service hoist was installed; the conveyance travels on rope guides which are suspended on tensioning devices located in the upper part of the headframe. A new ore wagon, giraffe and front end loader were added to the underground fleet of mining equipment. The ore wagon is equipped with a new suspension system using a nitrogen accumulator which is providing a much smoother ride than was obtained on the older models. Operator fatigue is consequently reduced and at the same time it is anticipated there will be less damage on the tractor frame from shock loads. A large electric powered mine ventilation door has been erected underground and an additional one planned. The recently installed direct fired, natural gas heaters at surface for heating the fresh air supplied underground through No. 2 shaft have proven satisfactory. Development footage in 1968 on the main level at 1,760 feet consisted of 8,846 feet of drifts 60 feet wide and 3,845 feet of drifts 35 feet wide. Total development footage to 31 December 1968 consisted of 73,555 lineal feet of drifts, and does not include 220 feet of drifting and 108 feet of raising driven for mine ventilation. A total of 1,467,180 tons of salt was hoisted; 1,763,200 tons were milled at an approximate average of 5,000 tons daily. Employment and Management The average number of employees was 172: 116 underground and 56 on surface. W. G. Muir was mine manager. 139 Annual Report for 1968

SULPHUR The production of Ontario's sulphur and sulphuric acid increased 31.95 percent from 234,448 tons in 1967 to 309,353 tons in 1968; while the value of production increased 98.65 percent from 52,354,010 to 54,676,198. Although some elemental sulphur in Ontario is recovered from the refining of nickel sulphides, the greater portion by far (99 percent) is represented by the sulphur content of liquid sulphur dioxide and sulphuric acid, manufactured from smelter gases in the Sudbury area, and in the Port Maitland area, from the roasting of zinc concentrates received from the mines in the Manitouwadge and Porcupine areas.

CANADIAN INDUSTRIES LIMITED (Industrial Chemicals Division) The Sudbury area plants of the company lie adjacent to the Copper Cliff reduction works and iron ore recovery plant of The International Nickel Company of Canada Limited. Sulphur-dioxide gas is utilized to manufacture liquid sulphur dioxide and sulphuric acid. Flash furnace gas from the Copper Cliff smelter is treated to produce liquid sulphur dioxide at the rate of about 270 tons per day. The old No. l sulphuric acid plant in this area has been phased out, but the drying facility, for pre-treatment of sulphur-dioxide gas, is still being used. Sulphuric acid of 99 percent is the drying agent used to reduce the moisture content of the gas with the resulting commercial grade of 93 percent sulphuric acid sent to market. Canadian Industries Limited has three sulphuric acid plants located alongside the iron ore recovery plant of International Nickel using roaster gas as the raw material for acid produc tion. The No. 4 acid plant came into production in April 1967 and is the largest metallurgical by-product sulphuric acid plant in the free world. The total acid production atthissiteexceeds 2,000 tons per day. The product is shipped by tank truck to the uranium mines and by tank car to Southern Ontario, Quebec, and to the United States. During 1967 the company commenced unit train shipping comprising 37 tank cars to points in Southern Ontario. The sulphuric acid and sulphur dioxide plants operated continuously during 1968.
