The Annual Report of the Resident Geologists 1 Section is issued in four parts to cover the eight offices as follows:
Part 1. Red Lake, Kenora, Thunder Bay. Part 2. Sault Ste. Marie, Sudbury. Part 3. Kirkland Lake, Timmins. Part 4. Southern Ontario.
These reports may be issued at separate times and not necessarily in the order listed above. Notices of their release will be mailed to those on the Department of Mines notification list.
Resident Geologists are stationed throughout the province to gather and disseminate information concerning the geology and mineral resources of their districts. At some offices one or more field geologists of the Geological Surveys Section may be permanently located with the Resident Geologist. The Resident Geologists maintain files of published and unpublished geological information pertaining to their districts. These include reports of work submitted for assessment credit, company prospectuses and reports from the files of the Ontario Securities Commission, reports of property visits by the Resident Geologist, reports donated by companies and individuals and various news items. All are available for public examination. Duplicate copies of assessment work for the whole province are also on open file in the Assessment Work Library, room 1522 of the Whitney Block, Parliament Buildings, Toronto.
On October l, 1969, the boundaries of most of the Resident Geologists© districts were changed to conform more closely with those of the Mining Recorders. Only in northwestern Ontario do these boundaries not coincide, owing to an additional Mining Recorder©s office at Sioux Lookout. The new boundaries of the Resident Geologists© districts are shown on the accompanying map.
The objective of this report is to summarize the highlights of the mineral industry in each district during the past year, and also to present any significant new information that may have a bearing on future mineral developments.

- viii - RED LAKE DISTRICT
By R.A. Riley1
INTRODUCTION From the point of view of exploration, 1969 proved to be the most active year in this District since the years immediately following World War II. Interest in the area stemmed in part from the gradual realization, by the major exploration concerns in particular, that the base metal potential in northwestern Ontario is relatively unknown, and this interest became acute as a result of an announcement in mid-January by Selco Exploration Company Limited that the company had discovered a body of high grade zinc-copper-silver mineralization on the west shore of Confederation Lake in Dent Township. This discovery resulted in the staking of over 9,000 claims in the Birch Lake-Uchi Lake metavolcanic-metasedimentary belt during the early part of 1969. The Geological Surveys Section of the Ontario Department of Mines was also very active in the District during the past field season. Mapping projects were undertaken in four widely separated areas including the Setting Net Lake area where L.D. Ayres continued his mapping of the Favourable Lake metavolcanic-metasedimentary belt, the Lang Lake area where a new mapping project was begun under the direction of K.G. Fenwick, Dent and Mitchell Townships where A.P. Pryslak began a continuing study of the Birch Lake-Uchi Lake metavolcanic-metasedimentary belt, and in the Lansdowne House-Fort Hope area where several thousand square miles of the Precambrian Shield were mapped by reconnaissance methods under the direction of P.C. Thurston and M.W. Carter. Mr. Pryslak joined the staff of the Red Lake office in April and will be stationed in Red Lake for the duration of his mapping project in the Uchi Lake area. The Red Lake Resident Geologist©s District increased in size during 1969 as a result of the attempt to more closely align the boundaries of the Resident Geologists© and Mining Recorders© Districts. The section added to the District includes the area bounded by Longitude 86 degrees on the west, Longitude 85 degrees on the east, Hudson Bay on the north and the Albany River on the south.

occupied a considerable part of the writer©s time. During the early part of 1969 a geological report by the writer on Glasgow, Meath, and Rennie Townships in the Districts of Algoma and Sudbury was submitted and placed on open file as Open File Report 5030. This report is now in final preparation for publication. A preliminary geological map of the north half of Mulcahy Township, Red Lake area, was completed by the writer and released in December.
Assessment files in the Red Lake office were completely recatalogued during 1969 and the filing system partly revised. Under the new system assessment data is filed according to township or, in areas where no townships exist, according to N.T.S. quadrants. Miss C. Mathew, the Geological Branch secretary, must be credited with carrying out the bulk of this revision. Mr. G. Winik, a local high school student, assisted the writer in both the field and the office during the summer and in particular, compiled considerable data on production and underground exploration within the District.
The writer, aided by Dr. B. Dutt of the Education and Data Retrieval Section and personnel from local mining companies, held classes for prospectors in Red Lake during the week of April 21 to 25. Short talks on rocks, minerals, and exploration techniques were also given to classes at the Red Lake Public School, the Red Lake District High School, and to the Red Lake Hi-C group.
In March the writer attended the Prospectors and Developers Convention in Toronto and was co-author of one of the papers presented. The writer also acted as a Department delegate at the meetings of the Institute on Lake Superior Geology held in Oshkosh, Wisconsin in May, and in September took part in a field trip sponsored by the Geological Branch of the Department of Mines in the Cobalt-Kirkland Lake area.
Field work during 1969 consisted primarily of property examinations, several of which will be described in a later section.
Many of the more significant showings in the District that were actively undergoing exploration were also visited. These included the Borland Lake silver-lead deposit, which was being drilled by Barymin Explorations Limited, the property of Golsil Mines Limited where underground exploration for silver-gold-lead-zinc mineralization was being conducted, the zinc-silver-copper orebody of South Bay Mines Limited on Confederation Lake, the former Rexdale Mines Limited zinc-silver-copper property at Snakeweed Lake, under option to Phelps Dodge Corporation of Canada Limited, and the molybdenum property at Setting Net Lake that was being explored by Asbestos Corporation (Explorations) Limited (now Minorex Limited) and Conwest Exploration Company Limited. Underground operations at Madsen Red Lake Gold Mines Limited and Campbell Red Lake Mines Limited and open pit and plant operations at the Griffith Mine were also visited. In addition to property examinations the writer carried out detailed mapping in Mulcahy and Byshe Townships and also examined outcrops along several stretches of highway within the Red Lake metavolcanic-metasedimentary - 5 -
belt. Two weeks were spent in the Fort Hope area and one week in the Armstrong area attached to Operation Fort Hope where the writer undertook several property examinations and some reconnaissance mapping. The volcanic and sedimentary rocks of the Lang Lake area were also examined over a period of a few days in the company of K.G. Fenwick who was engaged in a mapping project in that area.
MINING ACTIVITY During 1969, five District mines maintained continuous operations and underground exploration was being carried out on one other property. The principal developments at these mines are outlined below.
Campbell Red Lake Mines Limited During 1969, production from the Balmer Township property of Campbell Red Lake Mines Limited totalled 176,517* ounces of gold recovered from 261,609 tons milled. There were no significant new developments at the mine during the year.
Cochenour Willans Gold Mines Limited (Including Annco Mines Limited and Wilmar Mines Limited) Production figures for Cochenour Willans Gold Mines Limited and the adjoining properties of Annco Mines Limited and Wilmar Mines Limited, both controlled by Cochenour and mined through the Cochenour shaft, are given below: Tons milled Au* oz. Ag* oz. ^
Cochenour 14,147 2,229 112 84,244.94 Annco 12,359 3,606 160 136,190.78 Wilmar 45,068 14,198 9,506 553,538.05
Total 71,574 20,033 9,778 773,973.77 Compared to 1968, mill feed obtained from the Cochenour property decreased by about two-thirds and from the Annco property by about one- half; Wilmar production on the other hand nearly doubled. Production at Wilmar continued from the 1,300-foot and 2,050-foot levels, increased substantially from the 1,900-foot level, and commenced on the 1,450-foot level; development of the 1,700-foot level was also begun. As the Wilmar ore is free-milling, flotation and roasting of ore were discontinued during the year.
^Totals include estimates for December as final mint returns not available. - 6 -
Dickenson Mines Limited
(Including Robin Red Lake Mines Limited) During 1969, production at Dickenson totalled 168,002 tons from which 71,232 ounces of gold were recovered. Development continued from the No. 2 shaft with work concentrated on the 24th, 25th, 26th, 27th, and 30th levels and by year end development work from the No. 2 shaft was about 40 percent completed. Minor development in the No. l shaft area in the form of stope extensions and sub-level s was also carried out during the year adding some tonnage to the ore reserves. Production from the Robin Red Lake Mines Limited property, in 1969, totalled 6,270 tons from which 6,745 ounces were recovered. This ore was obtained from development work on the 16th, 17th, 18th, and 21st levels. The Robin property is mined through the Dickenson shaft and the ore processed in the Dickenson mill.
The Griffith Mine At the Stelco-owned Griffith Mine, during 1969, 951,115 long tons of natural pellets grading 63.43 percent Fe, 3.50 percent moisture, 4.77 percent Si02 J 0.52 percent Al, 0.06 percent Mn, and 0.02 percent P, were produced from 3,467,172 long tons of ore grading 26.65 percent Fe. Dewatering that part of Bruce Lake contained by the dike was essentially completed during the year with the removal of 1,532,340,000 U.S. gallons of water. Construction of the north perimeter dike from plant tailings got underway during 1969 and by December 31, 3,280 feet had been completed. In late 1969 installation of a pellet cooler in the plant was begun with operation scheduled for February, 1970.
Madsen Red Lake Gold Mines Limited During 1969, Madsen milled 238,473 tons of ore from which 60,579 1 ounces of gold and 10,133* ounces of silver were recovered. Continued development on the upper levels of the mine, particularly on the 6th and 8th levels, has made available substantial tonnages of previously broken ore which had been unavailable up to this time due to incompetent ground in the vicinity of the old stopes. Evaluation of the new No. 8 zone north of the shaft has been progressing slowly due to the presence of an incompetent unit of talcose rock on the hangingwall of the zone. To date the No. 8 zone has been most thoroughly investigated on the 24th level where it is about 250 feet long and 25 to 30 feet wide. Partial drilling both above and below this level has indicated upwards of 300,000 tons grading in the range of 0.30 to 0.35 ounces per ton. Although the drive from the shaft to the new ore zone on the 23rd level has not yet been completed, a raise is presently being driven from the 24th to the 23rd level.
lTotals include estimates for December as final mint returns not available. - 7 -
Golsil Mines Limited Exploration at the Favourable Lake gold-silver-lead-zinc property of Golsil Mines Limited during the year consisted of 187 feet of drifting on the 740 bottom level and 2,100 feet of diamond drilling. At year end a report by Golsil©s consultant was being prepared and was expected to be submitted to the company in early January.
EXPLORATION ACTIVITY Exploration activity in the District in 1969 showed a substantial increase over 1968. Claims staked in the Red Lake Mining Division during the past year totalled 10,999, a 4-1/2 fold increase over 1968. In that part of the Patricia Mining District within the Red Lake Resident Geologist©s District approximately 1,000 claims were staked, an increase of several hundred over 1968. The principal exploration targets in that part of the District lying within the Red Lake Mining Division include: a) The Birch Lake-Uchi Lake metavolcanic-metasedimentary belt, where numerous companies carried out geological, geophysical, and in some cases geochemical surveys in an attempt to duplicate the success of Selco Exploration Limited©s discovery on the east shore of Confederation Lake. b) The Red Lake area where several companies and individuals were actively engaged in the search for both base metals and gold. c) The Lang Lake area where several properties were being explored for base metals, and the iron ore potential of one property investigated. d) The North Spirit Lake area where geophysics, geology, and diamond drilling were used in the search for base metals and the ore potential of an iron formation tested by diamond drilling. e) The Favourable Lake-Bearhead Lake area where the Keevil Mining Group has been pursuing uranium mineralization using both geophysical techniques and diamond drilling. f) The Setting Net Lake area where Asbestos Corporation (Explorations) Limited (now Minorex Limited) and Conwest Exploration Limited investigated a low-grade molybdenite deposit by test pitting and diamond drilling. The principal activities in the Patricia Mining Division section of the District consisted primarily of staking with some follow-up exploration. The active areas include: a) The Big Trout Lake-Severn Lake area where Canadian Nickel Company Limited tested airborne geophysical anomalies with ground geophysics and diamond drilling. b) The Frog River area where a large block of ground was staked by Sherritt Gordon Mines Limited. c) The area east of Washi Lake where several blocks of ground were staked by a number of individuals. d) The area between Oshiski and Keezhik Lakes where several blocks of ground were acquired by Selco Exploration Limited after the completion of airborne geophysical surveys. A comprehensive list of the individuals and companies engaged in exploration within the District and the type and location of their exploration activities is given in Table l of Appendix I.
NEW INFORMATION
New Areas of Mineralization The Confederation Lake Area
Follow-up diamond drilling of airborne electromagnetic conductors by Selco Exploration Company Limited in the late summer of 1968 indicated the presence of high grade zinc-silver-copper mineralization on the east shore of Confederation Lake in the southeastern corner of Dent Township. Further drilling in the early part of 1969 indicated sufficient ore to a depth of 425 feet, at a grade of 14.11 percent Zn, 3.64 ounce Ag, and 2.24 percent Cu per ton, to justify a 500 ton per day mill. Production plans for the deposit were announced by South Bay Mines Limited, the operating company, on July 15th with production scheduled for early 1971. This orebody is the first sizable deposit of base metals known in the Birch Lake-Uchi Lake metavolcanic-metasedimentary belt and its discovery has touched off a major re-evaluation of this area.
New Types of Mineralization Porphyry Molybdenite Mineralization Molybdenite mineralization, occurring in a mode and association very similar to that at some of the large porphyry molybdenite mines in British Columbia, was investigated in the Setting Net Lake area. The mineralization consists of fine-grained molybdenite, pyrite, traces of chalcopyrite, and rare fluorite associated with narrow, closely spaced, steeply dipping quartz stringers. The quartz stringers are apparently filling joints along the northern edge of a porphyritic and more or less altered leucocratic biotite granodiorite-quartz monzonite stock. A more detailed description of this - 9 -
deposit is given by Ayres (1969d - see following section). A similar deposit in a biotite trondhjemite-granodiorite stock occurs south of Mink Lake in the Birch Lake area and is described elsewhere within this report.

Other Data
Through the kind co-operation of the Little Long Lac Gold Mines Limited the Resident Geologist acquired considerable material of a geological nature from the files of McKenzie Red Lake Gold Mines Limited. Most of the material pertained to properties in the Red Lake District upon which McKenzie had carried out exploration work, and in many instances provides the only record of exploration on some of the properties concerned. The Department is most grateful to the Little Long Lac organization for permitting the duplication of this material. Further, we would ask that any mining companies or individuals having data of geological or mining significance, which they may be willing to add to Department files, to contact the nearest Resident Geologist who will attend to collecting and(or) duplicating the material concerned. - 12 -
Road construction was underway on three fronts within the District in 1969. Work was continued on both ends of the Red Lake-Pickle Lake road during the year with approximately 8.5 miles of road constructed on the Red Lake section, for a total of about 17 miles, and 12 miles on the Pickle Lake section, including the installation of a bailey bridge over the Pineimuta River, for a total of 84 miles. Construction began on an access road from Goldpines in the Ear Falls area to the Confederation Lake property of South Bay Mines Limited in 1969. The old Uchi Lake road was rebuilt where possible; however, in several areas terrain necessitated the building of completely new sections of road. At December 31st the road had been completed for a distance of about 41 of its 45 miles. This road is being constructed under an agreement between the Ontario Government and South Bay Mines Limited whereby the company will be released from any contribution towards the cost of the road if the mine is brought into production within three years.
PROPERTY EXAMINATIONS
Can-Fer Mines Limited (A)
Location and Ownership The showing, consisting of molybdenite mineralization associated with a trondhj emite-granodiorite stock, is located a few hundred feet south of the 10th Base Line south of the east part of Mink Lake. The property was staked by Mr. E. J. Thomson in 1968 and transferred to Can-Fer Mines Limited in November of 1969. At the time of the writer©s visit to the property in August considerable stripping and trenching had been undertaken.
General and Economic Geology The host rock for the mineralization is a medium-grained, grey to pink, well jointed granitic rock with 2 to 6 percent biotite and ranging from trondhjemite to granodiorite in composition. In some areas, particularly near joints, the feldspars have turned dull green as a result of alteration. Cutting the trondhjemite with poor to well defined contacts are several syenodiorite dikes up to 3 feet thick composed primarily of plagioclase and up to l percent coarse-grained white carbonate and up to 2 percent combined molybdenite, pyrite, and sparse chalcopyrite. Weathering of the carbonate grains imparts a pitted texture to the surface of this rock. Also cutting the trondhjemite are pink, fine-grained quartz monzonite dikes. The relationship between the syenodiorite and quartz monzonite dikes is not known as contacts were not observed in the field.
^Letters indicate position on Figures l and 2. - 13 -
At the time of the writer©s visit to the property, mineralization had been exposed by trenching and stripping over an east-west strike length of about 800 feet with a possible thickness of 400 feet. In addition, a trench about 700 feet northwest of the main zone also contains molybdenite.
Molybdenite occurs in two modes. Clusters of molybdenite grains to 4 mm in diameter commonly occur with pyrite in the syenodiorite dikes. Molybdenite content in these dikes was estimated to range from less than 0.5 percent to 2 percent with a variable content in individual dikes. Pyrite occurs in medium-grained, subhedral and occasionally euhedral crystals or patches of crystals and rarely forms more than l percent of the dike.
Molybdenite, in estimated amounts up to 2 percent, also occurs in disseminated to patchy habit with pyrite along shallow (4 0 -15 0 ) south- dipping quartz stringers which range up to 1/2 inch in thickness. The quartz stringers may be as closely spaced as l or 2 inches, however more commonly they are separated by several inches to several feet of trondhjemite Molybdenite may also be disseminated in the wall-rock next to the quartz stringers but rarely for more than 2 inches.
Cull Property (B)
Location and History
In the late spring of 1969, Mr. Fred Cull of Red Lake staked one claim to cover a beryl showing in the Sandy Creek area. The showing is located about 1,000 feet east of Highway 105 and can be reached by a trail that leaves the highway about 3,500 feet north of Sandy Creek. The showing was discovered in 1962 by W.A. Gulbis and I.D. Tetlock who optioned the property to Madsen Red Lake Gold Mines Limited in 1963. The option was dropped later that year and the claims reverted to the Crown in 1964.
General Geology
The beryl occurs in a pink pegmatite dike up to 15 feet wide and exposed by stripping for a strike length of 190 feet. The easterly- trending dike is irregular in outline and as well as having several apophyses protruding into the feldspar-amphibole schist host along the north contact, there are also several inclusions of schist within the dike The dike essentially parallels the foliation in the schist and several similar pegmatite dikes and stringers, some of the augen variety, occur on both north and south sides of the main dike.
The pegmatite is medium-grained, varies from pale pink to white and consists predominantly of feldspar, grey smoky quartz, muscovite, minor beryl, and traces of apatite. Books of muscovite up to 5 inches long and 3/4 inch thick are common in several areas of the pegmatite and appear to be concentrated along narrow poorly developed shear zones; small books and - 14 -
flakes of muscovite are also sparsely distributed throughout the pegmatite. Minor blue-green and brown apatite occurs in small crystals within the dike, particularly near its north contact, and poorly developed tourmaline crystals are also found in felted masses along the north contact of the main dike. Present in two locations along or near the south side of the main dike are zones of well foliated, fine-grained, muscovite-quartz- feldspar pegmatite with a well developed augen texture. Beryl is not known to occur in this rock type.
Economic Geology
The only mineral of economic significance within the pegmatite appears to be beryl and the distribution of this material as seen in outcrop is shown on Figure 3. The beryl is pale green to white and occurs in subhedral to euhedral hexagonal crystals from about 1/4 inch to 3 inches in diameter with a vertical or near vertical orientation being predominant. The crystals commonly occur in muscovite-rich zones although rare crystals may be found within typical pegmatite. The most abundant concentration and largest beryl crystals occur on the north end of the most easterly trench. A grab sample consisting of about 3 pounds of fine- to medium-grained pegmatite containing several beryl crystals averaging about 3/8 inch in diameter returned 0.44 percent Be^ and about 0.1 percent Li. Semi- quantitative spectrographic analyses indicated the presence of Gr, Pb, Nb, and Sn in amounts between 0.01 and 0.10 percent and Mn and Ti in amounts between 0.05 and 0.50 percent. A second grab sample of about the same size consisted of about 10 percent smoky quartz, 25 percent muscovite and 65 percent white to grey feldspar. Beryl was not identified in this sample by visual examination; however, it contained 0.04 percent Be and semi- quantitative spectrographic analyses indicated the presence of between 0.01 and 0.10 percent Gr, Pb, Li, Mn, Sn, and Ti.
Horseshoe Lake Prospect (F)
Location and History Horseshoe Lake lies along the southeastern boundary of Mitchell Township and the showing occurs along the southeastern shore of the lake and a small near-shore island. The showing has been known since 1927 and was drilled by Heath Gold Mines Limited in 1951 and Norite Explorations Limited in 1964. The property presently forms part of the holdings of South Bay Mines Limited.

General Geology
As exposed on surface and in some old trenches the showing consists of a narrow zone of sulphide mineralization lying along the contact between a light grey to buff quartz-feldspar porphyry on the south and a buff to tan sericite-quartz-feldspar schist on the north. The mineralized zone trends N65E and dips vertically to steeply northwest. In outcrop the porphyry is very regular except for the inclusion of a few widely scattered small fragments of similar porphyry noted on a ridge a few hundred feet east, and it is interpreted as a pyroclastic, probably of ash flow derivation. Near the mineralized zone the porphyry becomes moderately schistose. The sericite-quartz-feldspar schist contains plagioclase and minor quartz phenocrysts but is more highly schistose than the porphyry. It is tentatively interpreted as either a felsic crystal tuff or a fine grained sediment locally derived from felsic volcanics.
On the southwest end of the showing a grey siliceous rock occurs on the north side of some trenches. This rock was poorly exposed but may represent silicification of the sericite-quartz-feldspar schist in the vicinity of the mineralized zone.
Economic Geology
Mineralization consists mainly of pyrite, some pyrrhotite, minor to trace amounts of sphalerite, and traces of chalcopyrite. Commonly pinching and swelling along strike, the mineralized zone was observed to range from 1-1/2 feet thick to 10 feet thick and is estimated to be composed of from l to 20 percent sulphide minerals. Narrow layers of massive pyrite and pyrrhotite up to 4 inches thick are locally present. Irregular quartz veins averaging about 3 inches thick and containing pyrite and rare pyrrhotite are common throughout the zone.
From the presence of sphalerite-rich muck surrounding the water- filled trench on the east end of the island it would appear that this is the best surface exposure of mineralization. The mineralized blocks of muck suggest a zone about 10 inches thick containing several 1/2 inch thick stringers of disseminated sphalerite and disseminations and very narrow stringers of chalcopyrite in a siliceous matrix. A hand specimen is estimated to contain 0.5 to l percent chalcopyrite, 3 to 4 percent sphalerite and 5 to 7 percent pyrite.
Toward the southwestern end of the showing pyrite occurs in laminae up to 1/16 inch thick in amounts up to 15 percent. Here it is generally most abundant on the southeast side of the zone and grades to a disseminated mode toward the northwest. Invariably this pyrite occurs with considerable siliceous material, most of which appears to be quartz.
Diamond drilling has indicated values up to 5.46 percent Zn, 0.91 ounce per ton Ag, 1.18 percent Pb and minor Cu and Au over thicknesses - 17 -
of from 5 to 14 feet^. Gay-Gray Property [C) Location and Ownership The property is held by E. Gay and Wm. Gray of Red Lake and is located in the vicinity of the Chukimi River and the north end of Keg Lake in Byshe Township.
General and Economic Geology The main trench is located about 600 feet from the northwest shore of Keg Lake and can be reached by a rather poor trail from the vicinity of an abandoned beaverhouse on the lakeshore. The trench has been blasted at a low angle across a narrow north-trending nose of mafic metavolcanics surrounded and probably intruded by medium-grained brownish grey quartz- feldspar porphyry. In contact with the porphyry on the north is a unit of intermediate lapilli metatuff containing vague fragments averaging about 2 inches long. The contact between the lapilli metatuff and mafic metavolcanics is not exposed. About 25 feet east of the trench fine grained gabbroic rocks are present and are interpreted as the coarse- grained phase of a mafic metavolcanic flow. Mineralization is mainly confined to the area of the nose of mafic metavolcanics within the porphyry although pyrite may be found in small clots within the mafic metavolcanics. Pyrite and minor chalcopyrite occur along fractures in the mafic metavolcanics and small shears in the porphyry and are disseminated in both rocks in amounts less than l percent. Two selected grab samples of mineralized mafic metavolcanics returned 0.42 percent Cu, 0.01 ounce Au, 0.21 ounce Ag, and 0.23 percent Cu, trace Au, and 0.15 ounce Ag respectively. One selected grab sample of porphyry contained 0.36 percent Cu and trace amounts of Au and Ag. Near the shore of Keg Lake, a few feet south of the trail, a trench blasted into mafic metavolcanics exposes a narrow quartz stringer accompanied by minor pyrite. On the east side of the Chukuni River about 300 feet south of Balmer Township approximately 100 feet of fine-grained, light grey to buff quartz- feldspar porphyry has been exposed by an old trench along the edge of a low hill. Disseminated and rare stringers of pyrite and chalcopyrite and trace amounts of native copper were noted in the porphyry. A typical grab sample of porphyry assayed 0.16 percent Cu and trace Au and Ag.

Hager-Gloster Property No. l (D)
Location and History
This property is located about 70 miles east of Red Lake on the north shore of an unnamed lake, 5 miles west of Senior Lake. Molybdenite was discovered on the face of an outcrop of granitic rocks by a trapper in late 1968 and the property was staked during early 1969 by a group of Red Lake businessmen including A. Hager and Dr. M.E. Gloster. Madsen Red Lake Gold Mines Limited optioned the property in the summer of 1969 but dropped the option late in the year after considerable trenching and sampling and minor diamond drilling.
General Geology
Molybdenite occurs in a zone about 100 feet thick associated with quartz-feldspar pegmatite and quartz veins that cut granitic rocks along their contact with hornfelsic mafic metavolcanics. On the main showing mineralization is exposed for about 450 feet in an east-west direction.
The oldest granitic rock in the area appears to be a grey, well- foliated, biotite granodiorite. This rock is cut by dikes of a pink, leucocratic medium-grained massive quartz monzonite. The north boundary of the mineralization is controlled by a large mass of medium-grained quartz monzonite that forms the north side of the ridge. Both rock types are cut by irregular pegmatite dikes and stringers. The pegmatites are composed primarily of feldspar, crystals of which may be 2 inches wide, an average of about 30 percent interstitial quartz, and up to 5 percent biotite, in books up to 1/2 inch in diameter. A few large irregular quartz veins are associated with the pegmatite and cut both granodiorite and quartz monzonite.
Economic Geology
Molybdenite occurs in the form of large hexagonal crystals disseminated in highly foliated grey granodiorite parallel to the foliation, in coarse knots within pegmatites or along the edges of the quartz veins, or simply as disseminated flakes within the pegmatite. Minor pyrite is also present and trace amounts of chalcopyrite were associated with molybdenite in quartz veins in one trench.
Approximately 2,000 feet west and a few hundred feet north of the main showing grains and crystals of molybdenite occur in narrow pegmatite stringers. Towards the north side of this zone the pegmatite stringers become more regular, the mineralization finer grained, and some fluorite is present. The host rock here is granodiorite similar to that at the main showing except for a yellow mottling resulting from plagioclase alteration. - 19 -
One rough chip sample of foliated granodiorite containing an estimated 2 percent molybdenite collected from the most easterly trench on the main showing returned upon assay 0.70 percent Mo. Four rough chip samples were taken from trench No. 6 on the main showing and two of these contained visible molybdenite. Only one of these samples returned assays of more than trace, this being 0.42 percent Mo from a sample consisting of molybdenite-bearing vein quartz and granodiorite.
Hager-Gloster Property No. 2 (E)
Location
A second property consisting of eight claims is located on the northwestern end of Senior Lake. A molybdenite showing occurs on the south side of an east-trending point in the bay on the northwestern end of the lake.
General and Economic Geology
Field examination suggests the host rock for the molybdenite is a fine-grained massive quartz monzonite. Medium-grained biotite granodiorite occurs on the northern side of the point and for several hundred feet farther north but is apparently barren of molybdenite mineralization.
The mineralization is very fine-grained and occurs in steeply south- dipping, east-trending quartz veins and veinlets. The largest quartz vein on the point is from l to 8 inches thick and is exposed for about 75 feet. The other quartz veinlets are less than 1/4 inch thick and are spaced from 6 inches to several feet apart. Minor pyrite is associated with the quartz stringers and surface oxidation has produced rusty patches on some of the veinlets. A grab sample of typical vein material from the large quartz vein returned 0.04 percent Mo.
Smith-Solterman Property (G)
Location and History
D.A. Smith and K.H. Solterman hold a group of eight claims along the south side of Wolf Bay, Red Lake. These claims cover part of the property formerly held by Perma Gold Mines Limited in 1945-1946, at which time considerable trenching and some geological mapping were undertaken.
General Geology The property is underlain from northwest to southeast by metamorphosed volcanic and sedimentary rocks including conglomerate and pyritiferous iron formation, intermediate tuff-breccia, and mafic volcanics. - 20 -
The metaconglomerate was examined only in one location and would appear to be separated from the pyritiferous iron formation by a unit of porphyritic lapilli metatuff. Where examined, immediately north of the lapilli metatuff unit, the metaconglomerate consisted almost wholly of rounded pebbles and cobbles of dark grey chert cemented by chert and up to 20 percent pyrite. According to Horwoodl the metaconglomerate farther northwest is of the normal sedimentary variety and composed dominantly of fragments of siliceous sedimentary rocks. The lapilli metatuff is light buff to tan on the weathered surface and grey on a fresh surface, contains quartz and feldspar phenocrysts, mafic fragments, both rounded and angular, and a few rounded fragments of porphyry. These fragments have a maximum length of about 1-1/2 inches and comprise less than l percent of the unit. Such features indicate that this rock is of pyroclastic origin rather than intrusive origin as indicated by Horwoodl.
The iron formation consists of regular to highly contorted bedded chert, magnetite, and from a trace to several percent pyrite. Outcrops are commonly gossan covered, rendering textures and structural features difficult to distinguish. Intermediate metapyroclastics contain brown to reddish brown fragments of dacite set in a dark green andesitic matrix. The fragments may be 3 to 4 inches long and weather slightly lighter in colour and higher in relief than the matrix. The mafic metavolcanics are dark green and usually fine grained. Near the shore of Red Lake these rocks become coarser grained as a result of recrystallization due to the presence of the Killala-Baird Batholith. Several strong linears trend southwest along the peninsula and considerable brecciation along one of these features suggests that they are, in part, of fault origin.
Economic Geology Much of the trenching and stripping undertaken on the ground by Perma Gold Mines Limited had been designed to investigate the pyritiferous iron formation but met with little apparent success. Several other trenches were located within the mafic metavolcanic unit on narrow silicified zones carrying medium-grained arsenopyrite. A grab sample collected from one of these zones by the writer and assayed by Cochenour Willans Gold Mines Limited contained 0.20 ounce per ton gold but no silver.

FUTURE EXPLORATION TRENDS IN NORTHWESTERN ONTARIO
(1) The trend in exploration in northwestern Ontario during the past decade has been away from gold and toward base metals, almost to the exclusion of gold in the past three or four years. The trend is expected to become even more prominent in the next few years. The most common technique now employed in the search for base metals consists of airborne electromagnetic and magnetic surveys, followed by ground geophysical definition of the anomaly, and then, if warranted, diamond drilling. This basic procedure is augmented in most instances by geological investigations and, occasionally, by geochemical techniques. Such procedures permit rapid coverage of large areas and are especially amenable to areas of low outcrop density. It would appear that the future trend in base metal exploration in northwestern Ontario will be toward greater use of airborne and ground geophysical techniques, especially the application of new techniques and instrumentation to areas "written off" on the basis of previous programs. (2) Ayres (1968)1 recently reported the presence of molybdenite and minor chalcopyrite along the north side of a porphyritic granodiorite stock near Setting Net Lake. During the past field season investigation of this mineralization by Asbestos Corporation (Explorations) Limited (now Minorex Limited) and Conwest Exploration Company Limited has shown it to be of the low grade porphyry copper-molybdenum type common to granitic rocks of western United States and British Columbia. Although the presence of a chalcopyrite-bearing porphyritic granodiorite stock had previously been reported from the Superior Province of the Canadian Shield (Davies 1965) , its significance was not fully appreciated and it was apparently dismissed by the mining industry as an anomalous occurrence. The recognition of porphyry copper-molybdenum type mineralization in the Setting Net Lake area and another occurrence of this type near Mink Lake in the Birch Lake area during the field season has aroused considerable interest among mining and exploration company personnel as to the possibility of economic porphyry copper-molybdenum deposits within the Superior Province of the Canadian Shield. Significantly, the possibility of their presence adds a totally new dimension to exploration in the Superior Province and converts hundreds of thousands of square miles of previously ignored "granite" into favourable prospecting ground. It is expected that during the next few years mining companies will make a concerted effort in the exploration for this type of deposit.

(3) A third trend that should develop during the next decade is the exploration of the Hudson Bay Lowland for Mississippi Valley type lead-zinc deposits. Sphalerite is already known to occur in these rocks from float found on the Nagagami River (Hamilton et^ a^., 1969)l and this, coupled with the fact that biohermal reefs are known to be present in associations with basement topographic highs, especially along the edges of the Cape Henrietta Maria Arch (Sanford et^ a^., 1968) 2 , would suggest that the Hudson Bay Lowland is prime prospecting ground. Unfortunately due to the lack of outcrop as a result of overlying Pleistocene and marine deposits, the area is not amenable to surface prospecting. Any exploration program in this area must therefore be preceded by careful site selection in order to eliminate costly detailed exploration of potentially unrewarding ground. This might be accomplished by geomorphological, geological, and seismic studies in conjunction with regional aeromagnetic studies that should give indications of possible basement highs and associated biohermal deposits. Site selection would then be followed up by induced polarization surveys and, if warranted, diamond drilling.

KENORA DISTRICT
By
H.L. King 1
INTRODUCTION
The Kenora Resident Geologist©s office is staffed by a secretary, Mrs. N. Robertson, a field geologist, J.C. Davies, and the Resident Geologist. Mrs. Robertson joined the Department in May. The office, presently located at 203 Main Street South, will be moved on January 31st to new facilities in the Provincial Building on Robertson Street. At our new location, the offices of the Ontario Department of Mines, consisting of the Geological Branch, Mines Inspection Branch, and Mining Lands Branch, will all be in the same building. This should greatly facilitate the interchange of information with the Mining Lands Branch and provide a much more efficient and convenient service to the public. Office administration, property examinations, rock and mineral identification, talks to schools, filing mineral exploration information, and probably most significant, discussions with prospectors and geologists account for a major part of the Resident Geologist©s time. An increase in exploration activity in northwestern Ontario, has resulted in more visits to the Kenora office by exploration people during the past year. In addition to regular duties, a mapping project was initiated covering the immediate Keewatin-Kenora area. This project will be continued on a part-time basis for the next two or three seasons. During the course of the summer, visits were made to three Ontario Department of Mines geological survey parties located in the Kenora area (see Figures 4 and 5 for location of map areas). Trips were also made to the Consolidated Canadian Faraday©s Gordon Lake Mine and to a rock quarry at Hawk Lake. Periodic visits were continued during the year to the towns of Fort Frances and Sioux Lookout with a view to being available for discussion with local prospectors. Thirteen property examinations were carried out in the course of the field season. Mineral exploration classes were held in Kenora in March. The classes were well attended with average attendance of 47 in the afternoon and 56 in the evening. Assistance in conducting the classes was provided by Department Geologists, J.C. Davies and B. Dutt; H, Bell and C. Walsten of the Mining Lands Branch; B. Whiddon of the Department of Lands and Forests; R. Cloth representing the Ontario Securities Commission and J. Campbell from Kerr Addison Mines Limited.

BOUNDARY REVISION OF KENORA RESIDENT GEOLOGIST'S DISTRICT
As part of a comprehensive revision of the Province's Mining Divisions and Resident Geologists' Districts, effective October 1st, the Kenora Resident Geologist's District was changed to take in the area east of Fort Frances to just west of Quetico (see figure on page iv). With the exception of the Patricia Mining Division, the new boundaries of the Mining Divisions in Ontario are now common with those of the Resident Geologists' Districts.
EXPLORATION AND MINING ACTIVITY
Staking Kenora Mining Division Claim staking activity in the Kenora Mining Division showed a slight decrease in 1969. A total of 2,364 claims were recorded, a decrease of 89 over the previous year. Figures 4 and 5 indicate areas of staking activity.
Patricia Mining Division
A major staking rush, sparked by Mattagami Lake Mines Limited base metal discovery at Sturgeon Lake, has resulted in the staking of a record number of claims in the Patricia Mining Division. The Mining Recorder's office at Sioux Lookout reported that 11,634 claims were recorded compared with 4,482 claims in 1968. An estimated 7,700 claims were staked in the Sturgeon Lake area since October 15th. The Kenora Resident Geologist's District includes only that portion of the Patricia Mining Division to the south of Pickle Crow and a breakdown of the number of claims staked only in this southern part was not available.
Quarry Permits A total of 95 quarry permits were issued or renewed for the Kenora District during 1969. All but one of these permits were issued for the removal of sand and gravel from deposits on Crown lands. One permit was issued for the removal of rock for use as track ballast by the Canadian Pacific Railway. - 33 -
Exploration
Exploration activity in the Kenora District showed a significant increase during the past year. A considerable increase in the number of claims recorded, in the amount of assessment work filed, and in visits to the office by exploration personnel, indicate that a definite upsurge in exploration took place in the Kenora District during 1969. The search for base metals predominated and continued to be widespread.
The highlight of the past year's exploration activity was the discovery of a major deposit of zinc, copper, silver, and lead in October at Sturgeon Lake by Mattagami Lake Mines Limited. As a result, exploration efforts of a number of companies working in the District have been concentrated in the general Sturgeon Lake area since the discovery. Prior to Mattagami's discovery, Canadian Nickel Company Limited, Amax Exploration Incorporated, and Selco were involved in exploration programs during the year in the general Sturgeon Lake-Savant Lake area. At year's end, most of the ground underlain by metasediments and metavolcanics at Sturgeon Lake and extending north to Savant and northwest to Sioux Lookout had been acquired by numerous individuals and exploration companies.
The search for uranium continued to be centred in the English River area, the Dryden to Sioux Lookout region, and the area 30 miles east of Kenora to Vermilion Bay. However, interest in uranium in the District during the past year appears to be lessening somewhat compared to that of 1967 and 1968.
A brief summary of exploration activity during the past year follows. The number preceding the name of the Company or individual indicates the areas on Figures 4 and 5 where work was carried out. An asterisk (*) after the name indicates some data is filed for the exploration activity listed. The number following the name is the N.T.S. number (most of the Kenora files are now filed under the N.T.S. system).

Mineral Production Base Metals The only base metal mining operation active in the District during 1969, was the Gordon Lake Mine at Werner Lake owned and operated by Consolidated Canadian Faraday Limited. Nickel and copper production from the Gordon Lake Mine for 1969 is estimated at 177,000 tons. Most of the ore milled was produced from sub-level blast-hole stopes in the A and H zones. Development drifting totalling 870 feet was carried out on the 700- and 1,300-foot levels during the year.
The mill at the Werner Lake operation was enlarged during 1969 to handle ore from the Dumbarton Mine, which went into production in September. The new Dumbarton Mine, jointly owned by Consolidated Canadian Faraday Limited and Maskwa Nickel Chrome Mines, a subsidiary of Falconbridge, is located in Manitoba, 25 miles west of Werner Lake. A scheduled 800 tons of ore per day will come from the Dumbarton Mine. - 36 -
Iron
The two iron mining operations at Atikokan, Steep Rock Iron Mines Limited and Caland Ore Company Limited, are now included in the Kenora Resident Geologist's District as a result of the boundary revisions implemented October l, 1969. The estimated shipment of pellets from Steep Rock's operation for 1969 is 1,402,500 tons. Red ore shipments for the year total 159,206 tons Estimated production figures from Caland's operation are: 878,000 tons of pellets, 833,348 tons of coarse ore, and 589,077 tons of fines (pellet plant feed).
Industrial Minerals
A rock quarry at Hawk Lake, 20 miles east of Kenora, was operated by B-A Construction Limited of Winnipeg. The operation, which ran from February 9th to November 29th, produced an estimated 295,496 cubic yards of crushed rock, which was used for ballast by the Canadian Pacific Railway
SIGNIFICANT NEW INFORMATION
Base Metals in a Felsic Volcanic Environment Published information**2 On the Mattagami Lake Mines Limited base metal discovery at Sturgeon Lake indicates that the zinc, copper, silver, lead sulphide deposit occurs within a zone of intermediate to felsic flows and pyroclastic rocks bounded to the south by a succession of intermediate to basic metavolcanic rocks. Although detailed descriptions of the host rocks have not yet been made public, the find has significant connotations. The association of base metal deposits and felsic volcanics in such areas as Flin Flon, Timmins, and Noranda for example, has been recognized for some time. However, Mattagami's discovery and Selco's base metal find at Uchi Lake within the past year, has established for the first time, the existence of valuable base metal deposits occurring in a felsic volcanic environment in this part of northwestern Ontario. There are several other recently discovered base metal occurrences in the area that may be cited as having a felsic volcanic association. Two such occurrences are the zinc, copper, silver, and gold recently discovered in a sheared rhyolite 2 miles east of Mine Centre, and the copper

mineralization in a rhyolite at Off Lake, 25 miles northwest of Fort Frances. The occurrence of finely disseminated copper and zinc sulphides in a rhyolite zone in Halkirk Township, east of Fort Frances could also be of significance when considering areas that may have potential. Two of the above-mentioned occurrences are briefly described under "Property Descriptions". The abundance of felsic volcanic rocks in a number of relatively unexplored sedimentary-volcanic belts in northwestern Ontario would certainly indicate that there are several areas that would provide good exploration targets.
New Maps and Literature Publications pertaining to the Kenora District and issued during 1969 are listed in the following section. Figures 4 and 5 show the location of new maps for the area. Four ODM mapping projects were undertaken in the Kenora District during the 1969 field season. The Western Peninsula area (Lake of the Woods) was mapped by a party lead by J.C. Davies. Mapping in the Rainy Lake area was continued under the direction of F.R. Harris, and the Bell Lake-Sturgeon Lake area was mapped by N.F. Trowell and assistants. The author, aided by one assistant, commenced mapping the Keewatin-Kenora area.

NEW INFORMATION ADDED TO RESIDENT GEOLOGIST'S FILES
New information added to the files in 1969, consisted mainly of work submitted for assessment credit. Other data added were two Ontario Securities Commission reports, and 13 property reports by the Resident Geologist. Files for the Fort Frances to Quetico area, previously located at the Thunder Bay office, are now at Kenora as a result of the changes in the boundaries of the Resident Geologists' Districts. The amount of assessment work recorded in the Kenora District in 1969, showed a considerable increase over work submitted in 1968. Information from the Mining Recorder's office in Kenora indicates that assessment work calculated in man-days for the Kenora Mining Division increased from - 40 -
39,266 in 1968 to 43,646 man-days during 1969. The Mining Recorder's office at Sioux Lookout reports that assessment work increased from 54,327 in 1968 to 62,168 man-days in 1969 for the Patricia Mining Division. Most of the increase was due to more diamond drilling. Details of the information added to the files are found in Appendix II.
PROPERTY EXAMINATIONS
G.L. Pidgeon Property (A)* Sphalerite mineralization with minor amounts of pyrite, chalcopyrite, and galena was discovered about 2 miles east of Mine Centre, by G.L. Pidgeon of Wabigoon, during the fall of 1968. A metamorphosed, sheared, felsic volcanic, probably a rhyolite flow in part fragmental or tuffaceous, is the host rock for the mineralization. Silver is associated with the sphalerite in a ratio of about 15 zinc to l silver. Traces of the sphalerite mineralization can be found over an area about 6,000 feet long and nearly 1,000 feet wide but the four most significant occurrences are scattered over a distance of about 1,000 feet. The most strongly mineralized zones are confined to the areas of most intense shearing. At the main showing, 3 stringers of massive sphalerite, each about 3 to 4 inches wide are separated by 2- to 3-foot zones of less strongly mineralized rock. The zone of mineralization at this showing is about 35 feet wide and probably runs about l percent zinc across this width. A chip sample across 8 feet ran 2.75 percent zinc, 0.35 percent copper, and 0.40 ounces silver. Kerr Addison Mines Limited conducted geophysical and geochemical surveys on the property during the past summer, followed by 6 packsack drill holes. Their drilling results were disappointing, and indicated that the zones were discontinuous in length and depth. Since significant amounts of zinc mineralization with minor copper, silver, and gold occur over a relatively large area, further work in the form of detailed mapping may be warranted.
Corrigan Property (B) Several interesting gold prospects, which first received some attention in the 1940s by E. Corrigan, of Emo, have recently been re-examined. The showings are located in Halkirk Township, at the east end of Swell Bay on Rainy Lake.
* Letter in brackets refers to location letter on Figures 4 and 5. - 41 -
The area in the vicinity of the gold occurrences is underlain by gabbro and basalt. Quartz veins occupy tension fractures and shear zones within the gabbro. Gold occurs in some of these quartz veins. The quartz veins are narrow and appear to be discontinuous. One zone is up to 6 feet wide but generally the veins are in the order of 6 inches to 2 feet in width. Minor sulphides, mainly pyrite and a few specks of galena are associated with the quartz veins. Minor amounts of platinum are also present. Exceptionally high assays are reported from some of the narrow veins and one of the wider zones is reportedl to have run S28.70 in gold across 4 feet. Although the gold-bearing quartz veins appear to be small and of rather limited extent, a small, high-grade type of operation could be profitable.
Lakatos-Cousineau Property (C) Copper, molybdenum, and zinc mineralization has recently been discovered in the northwestern part of Halkirk Township by Steve Lakatos and Robert Cousineau of Fort Frances. Finely disseminated sulphide minerals occur in a rhyolitic zone that is several hundred feet thick and 1/4 mile in length. Traces of sulphide minerals were noted throughout the rhyolite. In several places where the sulphides, mainly pyrite and pyrrhotite, have been localized along fracture surfaces and minor shears assays of up to 0.44 percent copper and 0.66 ounces of silver were obtained. About 1/4 mile to the north of the rhyolite zone, chalcopyrite and molybdenite were found associated with a sugary quartz vein, which occurs along the contact between granodiorite and a zone of intermediate to basic metavolcanics. Adjacent to the quartz vein, disseminated chalcopyrite and molybdenite were also noted over a small area of several square feet within a network of fractures in the granodiorite. The showings do not represent potentially economic concentration of mineralization, but further prospecting along the contacts of the rhyolite zone and also along the contact between the granodiorite and volcanic belt is definitely warranted.
Hupchuk Property (D) A zinc occurrence on Pine Point on Rainy Lake has recently been staked by M. Hupchuk of Fort Frances. The sulphide mineralization is associated with a highly sheared zone of chlorite schist containing numerous quartz eyes. The outcrop of schist is exposed over a width of about 100 feet and a length of 150 feet. The schist is in contact with gabbro to the south.
Corrigan, Emo, Ontario. Personal communication. - 42 -
The sulphide mineralization consists of scattered, discontinuous streaks and stringers of mainly sphalerite, pyrrhotite, pyrite, and minor chalcopyrite. Traces of mineralization can be found across a width of about 100 feet. However, only a zone about 15 feet wide at the north end of the outcrop contains sulphide minerals of up to 10 percent.
Although the known mineralization is too low grade to be of economic interest, there is a possibility that better concentration of sulphide minerals may be found along strike.
Grassy Portage Bay Property (E)
Diamond drilling of a copper-nickel property in Halkirk Township is currently being undertaken by Seemar Mines Limited. The property is under option from Noranda Exploration Company Limited, who has carried out work intermittently on the property since 1958.
Previous drilling, several years ago by Noranda, indicated 64,000 tons in the "B" zone grading 3.05 percent copper*. Several good intersections of copper mineralization have been obtained during the drilling carried out this year by Seemar Mines Limited.
The copper and nickel sulphides are associated with a gabbro that varies considerably in appearance and composition. Chalcopyrite and pyrrhotite occur disseminated throughout the gabbro over a strike length of about 350 feet and a width of about 15 feet on the surface. Locally the sulphide minerals are somewhat more concentrated, occurring as irregular pockets of chalcopyrite, pyrrhotite, and pyrite. The gabbro in which the mineralization occurs is in contact with a zone of amphibolite to the north. No major structural control on the emplacement of the sulphide minerals is evident on the surface.
Daley-Galbraith Property (F)
During the past few years, a considerable amount of prospecting, trenching, and some diamond drilling has been undertaken on several copper-nickel showings in Watten Township, by T. Daley and J. Galbraith of Fort Frances.
At the showing just south of Highway 11, at the Nickel Lake turnoff, pyrite and pyrrhotite with minor sphalerite and chalcopyrite occur in a steeply dipping, highly sheared, sericite schist zone. The main mineralized shear zone within the schist is about 6 feet wide and exposed for a strike length of about 110 feet. Grab samples taken from the zone ran 0.28 percent copper and 0.18 percent nickel.
iNorthern Miner, October 2, 1969. - 43 -
At another showing on the property, sulphide minerals are localized along pillow selvages in basalt. The mineralization, which is of rather limited extent, consists of mainly pyrite, pyrrhotite, with minor chalcopyrite.
Trenching at another location on a poorly exposed outcrop on the edge of a muskeg has exposed sulphide minerals in a zone of metasediments Pyrite, pyrrhotite, and minor chalcopyrite occur as streaks within a fine-grained, light grey quartzite.
The showings examined did not have significant amounts of copper and nickel sulphides, but they do occur in a favourable geological environment. A geophysical program in the area included by the showings would appear to be warranted.
Nabish Lake Property (G)
A detailed exploration program has been conducted during the past year by Hollinger Mines Limited on a copper-nickel property located about 10 miles southwest of Dryden. The property was optioned from A. Kozowy of Dryden in 1968 and the company has subsequently undertaken geophysical surveys, geological mapping, and some diamond drilling.
Copper and nickel sulphides occur in the vicinity of the contact between volcanic rocks and gabbro. The volcanic rocks range in composition from intermediate to basic and are both fragmental and massive.
The sulphides, consisting of pyrrhotite, pyrite, and chalcopyrite, found in the northern part of the property about l mile northwest of Nabish Lake, are localized along a shear zone that cuts an intermediate to felsic fragmental volcanic. About l mile to the southwest, disseminated pyrrhotite, pyrite, and chalcopyrite occur in a volcanic breccia of intermediate to mafic composition. The breccia has been locally invaded by diorite and gabbro.
In general, the sulphide mineralization at Nabish Lake appears to have been localized by shearing and associated minor brecciation.
Alcock Property (H)
An occurrence of sulphide minerals and native copper was recently discovered, in the High Lake area, by C. Alcock. The showing is located about 1-1/4 miles east of High Lake, about 1/4 mile south of a road that joins High Lake with the Shoal Lake road.
Disseminated pyrite and chalcopyrite occur along a silicified shear zone in basalt. About 200 feet to the east, disseminated specks of native copper were found over an area of several square feet in a fractured basalt. The native copper appears to be located mainly along minute fracture planes; however, some specks were noted in massive basalt. - 44 -
More work is planned to establish the extent of the poorly exposed zones of copper mineralization.
McCombe Property CI) An interesting porphyry-type copper occurrence was discovered on Minnitaki Lake during the 1950s by R. McCombe of Sioux Lookout. No work has been done on the showing but some geophysical work and drilling was done immediately to the east of the showing by Rio Tinto Corporation during the early 1950s. The copper mineralization is found in a quartz-feldspar porphyry at the eastern end of the long narrow peninsula that separates Pickerel Arm from the main part of Minnitaki Lake. Disseminated pyrite and chalcopyrite occur in a quartz-feldspar porphyry over an area of at least 2,500 square feet. The sulphide content generally ranges from 2 to 5 percent with pyrite the main sulphide and chalcopyrite occurring in lesser amounts. The mineralization appears to be concentrated, to some extent, along minute fracture planes; lesser amounts occur disseminated throughout the porphyry. Two grab samples of the mineralized quartz- feldspar porphyry ran 0.44 and 2.56 percent copper, and 0.16 and 0.26 ounces silver respectively.
Overburden covers most of the area underlain by the porphyry and outcrop is scarce; therefore, actual extent of the mineralization is not known. However, the nature of the occurrence suggests that the mineralization could be widespread and therefore the showings warrant further attention.
Daley, McTavish, and Klook Property (J)
The presence of radioactivity emanating from a shallow trench in sandy overburden in Breithaupt Township was first noted several years ago by Peter Klook of Fort Frances. The occurrence is located near Sunstrum Station where extensive sandy overburden overlies an area of what appears to be mainly granitic rocks. In an attempt to obtain a sample, casing was driven down through the sandy overburden and encountered bedrock at 20 feet. But due to drill problems, only a few chips of granitic rock were recovered. The reported radioactivity is most readily accounted for as being caused by radon gas that has apparently been dissolved in ground waters and migrated to the surface through the 20 feet of sandy overburden. The source of such radioactive gas would no doubt be either uranium minerals in the granitic bedrock or a secondary concentration of radioactive elements between the Precambrian bedrock and the overburden.
Readings were taken with a 3-channel scintillometer (McPhar Model TV-1) in an attempt to check the occurrence but the results were inconclusive. Readings taken were generally similar to the background - 45 -
count, except for occasional sporadic counts of 2 times background. It is recommended that a radon counting device be employed to test for the presence of suspected radon gas.
Qneman Lake Property (K) During the summer of 1969, Kerr Addison Mines Limited evaluated a quartz-rich shear zone containing disseminated arsenopyrite and sphalerite located on the east shore of Oneman Lake. The mineralized zone contains disseminated arsenopyrite, pyrite, pyrrhotite, and traces of sphalerite and galena over widths of up to 4 feet. The zone can be traced for a distance of about 200 feet; its eastern extension is hidden by overburden. The host rock is a zone of hornblende-rich metasediments surrounded by granite. An electromagnetic survey was conducted over the zone and one hole was drilled to a depth of 116 feet under the main showing. Only low values in zinc and gold were obtained.
RECOMMENDATIONS FOR FUTURE MINERAL EXPLORATION Several occurrences of copper and molybdenum mineralization associated with granitic quartz porphyry and quartz-feldspar porphyry masses have been found throughout this district over the past few years. Examples of this type of mineral occurrence are the porphyry copper showings* at High Lake, west of Kenora, the disseminated copper in quartz- feldspar porphyry on Minnitaki Lake, and the porphyry copper-molybdenum deposit^ on Beidelman Bay, Sturgeon Lake. A molybdenum occurrence^ in a granite at Bears Pass in Halkirk Township, east of Fort Frances is another example of this type of disseminated, low-grade type of mineralization. The known porphyry-type copper and molybdenum mineralization in the District appears to be associated with relatively small granitic stocks, at least some of which are near surface intrusions, occurring within belts of metasedimentary-metavolcanic rocks. A careful examination of some of these small granitic stocks occurring within this particular environment may be warranted. iDavies, J.C., 1965: High Lake-Rush Bay area; Ontario Dept. Mines, Geol.

THUNDER BAY DISTRICT By C.R. Kustra1
INTRODUCTION On October l, 1969 the boundaries of the areas served by the Mining Recorder and the Resident Geologist were made coincident. These branches of the Department of Mines, located in Thunder Bay, currently service a region, recently renamed the Thunder Bay Mining Division, approximating 43,500 square miles in area. Two field geologists, F.R. Harris and K.G. Fenwick, are stationed in the Thunder Bay office. The former commenced a geological mapping program of two year's duration in the Shonia Lake area; the latter completed geological mapping of Halkirk and Farrington Townships. G. Johns, geological assistant, joined the local staff in May, 1969. Activities of the Resident Geologist were varied. In addition to the normal duties concerned with consultation, rock and mineral identification, and office administration, the writer participated in outdoor teacher workshops, student field trips, lecturing to elementary and secondary school students, and conducting Junior Forest Ranger classes. Geological survey parties in the area were visited as well as several of the mining operations. Activities indirectly related to the Resident's duties included Chairmanship of the local branch of C.I.M.M., Secretary of the Northwestern Ontario Regional Advisory Board, Department representative to the Mid-Canada Development Corridor Conference and Chairmanship of the field trip committee, Institute on Lake Superior Geology. The latter organization will meet May 7 to 9, 1970 in Thunder Bay for technical sessions and field trips. E.B. Freeman, the Department's geological lecturer, conducted successful Mineral Exploration classes in November, 1969. A Special Topics series, involving resource personnel from Lakehead University and exploration is scheduled for the latter week in January, 1970. It is hoped that a field course, limited to 20 students, can be held this spring. A panel display and mineral exhibit was arranged by the Department during the Canadian Lakehead Exhibition.

STAFF ACTIVITIES
Four geological survey parties were stationed in the District during the 1969 mapping season. Operation Fort Hope, under the guidance of P.C. Thurston and M.W. Carter, saw completion of the mapping of approximately 18,000 square miles by helicopter reconnaissance and ground traverse. W.O. Mackasey mapped Eva and Summers Townships in the Beardmore area and J.F. Giguere completed geological mapping of about thirty islands between Nipigon Strait and Schreiber Channel, in the northern part of Lake Superior. A surface mapping program, scale l inch to 800 feet, in the Manitouwadge area was completed by V.G. Milne.
A brief description of the above projects is found in "Summary of Field Work, 1969"; Ontario Dept. Mines, Miscellaneous Paper 32, edited by E.G. Pye.
Four projects are scheduled in the District for the 1970 field season. A combined geochemical and geological mapping program, under the leadership of W.J. Wolfe and M.W. Carter respectively, will cover a large region in the Rossport-Schreiber-Dickison Lake area. W.O. Mackasey will continue mapping in the Beardmore district, covering Barbara, Meader and Pifher Townships. F.R. Harris will commence mapping Hagey and Conacher Townships in the Shebandowan district and W.H. Mcilwaine will map Black Bay Peninsula.
EXPLORATION AND MINING ACTIVITY1
Staking and Exploration
Exploration activity in the Thunder Bay Mining Division was relatively heavy and widespread. A general increase in activity, manifested by work performed and number of claims staked, was noted. An increase in the tempo of activity occurred at the end of the year and continued into 1970. The number of claims recorded in 1969 surpassed the 1968 figure by about 23 percent, due to a sharp increase of staking during the latter part of the year.
Concentrated staking activity occurred in the Graham area (A), the Shebandowan area (B) where a large exploration company holds a contiguous block of over 300 claims extending from the western part of Shebandowan Lake to the Quetico border, and the Beardmore district (C). Attention in the latter area has been focussed by at least two well known companies on base-metal exploration.
^Specific locations of areas or properties are indicated by a letter or number enclosed by parenthesis and located on the map of the Resident Geologist's District (Figures 6 and 7). - 55 -
Much attention has been directed to the exploration of metavolcanic complexes and focussed particularly at the felsic-mafic interface. Examination and re-examination of these complexes, especially those covered with a thick mantle of drift, has occurred. The occurrence of economic base-metal deposits at or near the contact between felsic and mafic metavolcanic units is well known. A careful and systematic examination of the metavolcanic complexes, employing sound geological concepts and sophisticated instrumentation, is warranted. In the Pigeon River area, exploration continued at a good pace in 1969. In addition to several prospects worked by smaller concerns, Bordun Mining Corporation (1) completed four diamond drill holes to test previously located copper-nickel mineralization-^. Imperial Minerals (2) diamond drilled in Pardee Township^, and Caprive Oil and Gas (3) acquired a claim block in Crooks Township, planning a geophysical survey and diamond drilling^. By far the most active property in the Pigeon River area is Great Lakes Nickel Limited (4). The product of a merger between Great Lakes Nickel Corporation and Thunder Bay Nickel Corporation, the company is continuing diamond drilling on its large tonnage copper-nickel prospect. Feasibility studies have been completed for a mining-milling-smelting complex and shaft sinking is scheduled to start early in 1970. The International Nickel Company of Canada is continuing development of its Shebandowan Mine (5) in addition to conducting an active exploration program in various parts of the District. Creswel Mines Limited (6) completed a limited amount of underground mining and milled a small amount of ore during 1969. Surface plants constructed to date include a mill of 50 to 60 ton capacity, machine shop, and dry, headframe, and hoist house. Over the past two years, the company undertook surface geological and geochemical surveys, diamond drilling, and bulk sampling. Chimo Gold Mines and Nakina Mines (7) completed geophysical surveys on their property in the Makokibatan Lake area preparatory to diamond drilling4 . In the Juneau Lake area, Mogul Mines and North Coldstream Mines (8) continued diamond drilling on a base metal prospect. Mineralization of the B-4 anomaly has been traced for 1,750 feet and tested to a depth of 200 feet^.

Carravelle Mines (9) planned diamond drilling on its Pulfa prospect in the Manitouwadge area. Drill targets were delineated as a result of geophysical surveys*. In the Marshall Lake area, Kendon Copper Mines (10) continued to diamond drill its base metal prospect, planning to extract 700 pounds of core for mill testing^.
Halren Mines (11) completed diamond drilling a silver-lead-zinc prospect in Township 80. A total of 11 holes for an aggregate footage of 3,218 feet were drilled. Chesterville Mines Limited (27) plan an induced polarization survey and additional diamond drilling on their copper-nickel prospect in the northwestern corner of Elmhirst Township. Drilling to date outlined a mineralized zone 1,000 feet in length with an overall thickness of 40 feet. The total known tonnage is estimated at 937,538 tons grading 0.49 percent copper and 0.49 percent nickel^.
Six mines operated in 1969. These are listed in the index to the map of the Resident Geologist's District. Thunder Bay Amethyst Mines Limited produced approximately 550 tons of amethyst and amethystine stone^. Zenmac Metal Mines Limited continued limited operations into 1970 and conducted exploration activity in several parts of the District.

PROPERTY EXAMINATIONS 1
Acorn Mining Syndicate (12}
Location The Acorn Mining Syndicate acquired a block of claims located in the northwestern corner of Conmee Township, approximately 25 miles west of Thunder Bay, Ontario.
Geology The claim group is partly underlain by a lens-shaped body of fine grained, dark green peridotite, locally serpentinized and asbestos-bearing. The area was initially selected as a possible source of kimberlite, a favourable host rock for diamonds. A ground magnetometer survey outlined four elliptical easterly-trending anomalies, two of which were subsequently drilled. Three holes, aggregating 1,204 feet, were completed. Core logs of these holes, filed at the Thunder Bay Resident Geologist's office, indicate that peridotite and some dunite was encountered. At the time of the writer's visit, anomaly A-l was tested by a 439-foot hole; drilling was in progress on anomaly B-l, reaching a depth of 129 feet.
W. Acker (15) Location The Acker occurrences are located approximately 1.5 miles north- northwest of the southwestern corner of Glen Township, 40 miles northeast of Thunder Bay, Ontario.
Geology The property is underlain by flat-lying sediments (argillite and dolomite) of the Sibley Group, overlain conformably by remnants of a flat- lying diabase sill. A northeast-trending breccia zone (strike N50E) cuts
•^Properties located on the map of the Resident Geologist's District (Figures 6 and 7) are numbered in parenthesis. - 60 -
the rocks and consists of quartz-barite-calcite gangue mineralized with galena, sphalerite, and lesser amounts of chalcopyrite. The zone has been traced intermittently for over 1/2 mile and is regarded by the writer as the strike extension of the "Lebel" vein^, situated l mile to the southwest.
Mineralization
The No. 2 lead vein, exposed for a strike length of 70 feet, occupies a fault zone in red argillite, chert, and dolomite. The vein is 15 to 20 inches in width, strikes N60E and dips 70S. It consists of pink and white barite and quartz enclosing angular fragments of host rock, and is mineralized with galena and chalcopyrite. Galena occurs as massive veins, l to 2 inches wide, and as pods of irregularly distributed crystal aggregates Chalcopyrite appears to be generally limited to the dolomitic parts of the host rock at the wall of the vein and occurs as fracture fillings and broad splashes. The main zinc showing is exposed on the south side of a small pond located 1/2 mile southwest of the No. 2 lead vein. The vein, exposed intermittently by trenches for 200 feet, fills a 3-foot fracture in reddish- brown dolomite. It consists of white barite, quartz and a small amount of calcite mineralized with yellow coloured sphalerite and lesser amounts of galena. A 3-foot chip sample of the vein, heavily mineralized with sphalerite, returned 6.70 percent zinc and a trace of cadmium .
W. Forsgren (14) Location The Forsgren occurrences are situated in the northwestern part of Conmee Township and cover parts of concession 6, lots 11 and 12.
Geology and Mineralization The property is predominantly underlain by mafic to ultramafic rocks of gabbro and peridotite. A small part of the southern part of the Forsgren claim group is underlain by mafic metavolcanics and metasediments of Archean age. The writer was taken to several showings on the property. On the north side of Marble Lake, near its southeastern end, a 6-foot by 7-foot pit, blasted into the side of a hill, exposes a gossan-bearing, highly sheared mafic metavolcanic rock trending S60E and dipping 80SW. Slightly sheared, lightly serpentinized gabbro outcrops a few feet to the north of the pit.

A narrow fine-grained, massive diabase dike cuts the metavolcanics at a slight angle to the foliation. Foliation planes in the metavolcanics are partly filled with pyrrhotite and trace amounts of chalcopyrite. Sulphide mineralization makes up l percent to 2 percent of the rock and is exposed over a width of 3 feet. Approximately 300 feet along the shore towards the western end of the lake, a vertical wall, parallel to the lake shore and 20 feet high, exposes a narrow carbonate-filled shear zone in metavolcanics. The shear zone, l inch to 5 inches wide, contains a small amount of disseminated chalcopyrite and magnetite.
G. Holman (15) Location The showing is located on the southwestern shore of Peep Lake, approximately 8.5 miles south of Beardmore, Ontario.
Geology and Mineralization Fine grained, slightly foliated intermediate metavolcanics, striking N60E and dipping 70NW, outcrop on the southwestern shore of Peep Lake. Conformable to the foliation is a series of white to grey quartz veins, exposed over a strike length of 40 feet and confined to a width of 15 feet The quartz veins vary in width from 1/2 inch to 8 inches and are lightly mineralized, locally with pyrite and chalcopyrite. A grab sample of the mineralized quartz showed trace amounts of gold and silver^.
M. Johnson (16)
Location This occurrence is located on the Johnson farm, concession 6, lot 4, Conmee Township. Geology and Mineralization The farm is underlain by intermediate to basic metavolcanics of Archean age. A mantle of drift covers much of the farm area. At the time of the writer's visit, the owner had bedrock exposed in a pit 8 feet by 5 feet and 4 feet deep. Bedrock here is a fine-grained buff weathering felsic volcanic breccia consisting of moderately angular fragments,
^Analysis by the Laboratory and Research Branch, Ontario Department of Mines. - 62 -
1/2 inch in diameter to some measuring 7 inches by 4 inches. The felsic fragments are fine grained, cream to pinkish on fresh surface, partly epidotized, and weather to a chalky textured, buff coloured surface. The enclosing matrix material is very fine grained and dark grey in colour. Chalcopyrite occurs as irregularly distributed patches and fracture fillings, in amounts 2 percent to 5 percent. A grab sample of the better mineralized material returned 0.04 ounces gold per ton, 0.63 percent copper and trace amounts of silver and nickel 1 .
A. Michielli (26) Location The property is located in the southeast quarter of section 54, Mcintyre Township, within the city of Thunder Bay. The Lakehead Expressway passes 500 feet northwest of the occurrence.
Geology and Mineralization Rock exposure here is very scarce and is confined to a northeasterly- trending outcrop area, 500 feet long and 200 feet wide, that rises gently out of a muskeg terrain to a maximum height of 15 feet. A black, fine-grained diabase sill, of undetermined thickness, partly overlies grey, thinly bedded argillite of the Gunflint Iron Formation. The argillite and sill strike northeasterly and dip gently southeast. Trending northeasterly and dipping vertically, a narrow fracture zone, confined to a width of 10 feet, contains several narrow veins of quartz, amethyst, and minor calcite. The veins range in width from 1/2 inch to 12 inches and average 3 inches to 5 inches. They appear to be arranged in en echelon fashion in the direction of strike. Mineralization is sparse and consists of discrete grains of galena and sphalerite with lesser amounts of pyrite and chalcopyrite. Two samples of mineralized vein material returned trace amounts of silver 2 .

0. Paju, Caribou Mine Location (17)
Location The property is located in the north half of Mining Location 6, McTavish Township, approximately 36 miles northeast of Thunder Bay, Ontario.
Geology The general geology of the area and the Caribou Mine is described by Tanton1 . The writer was taken to one of the several quartz-barite-calcite veins found on the property. The vein is located approximately 500 feet south of an adit and trends N80E and dips 70S. The vein varies in width from 10 inches to over 3 feet and can be traced for a strike length of at least 250 feet. It is localized along the contact between red argillite of the Sibley Group and red, massive granite of Archean age. A narrow diabase dike, apparently pre-mineralization in age, occupies part of the contact zone.
Mineralization At the western end of the vein, a 10 inch gangue-filled fracture is exposed. The vein here is bounded on its north side by granite and by diabase on its south side. Siltstone outcrops within 10 feet of the vein. Mineralization consists of galena, making up 10 percent of the vein material, and minor amounts of sphalerite and pyrite. A sample of mineralized vein, chipped across a width of 10 inches returned 0.42 ounces silver per ton, 19.0 percent lead and 0.90 percent zinc^. Approximately 150 feet east along the vein, a trench exposes several narrow veins confined to a width of 4 feet. The veins occupy narrow fractures in diabase that is bounded on its north and south sides by granite. Mineralization consists of galena occurring as massive streaks, up to l inch wide, and as disseminated crystals. A composite sample of mineralized vein material taken across a width of 3 feet returned 0.23 ounces silver per ton and 30.9 percent lead^.

D. Wilkinson (18)
Location
The Wilkinson showing is located in the northwestern corner of Pic Township, l mile east of Marathon, Ontario.
Geology
The claim area is underlain entirely by the augite syenite unit of the Port Coldwell alkalic complex. At the time of the writer's visit, one small pit exposed fresh material. The rock is medium- to coarse-grained, massive and dark brown on fresh surface. It consists of augite, perthitic feldspar, and a minor amount of magnetite. Noticeable on the fresh surface are colourful cleavage flashes of perthitic feldspar exhibiting hues of deep to light blue and gold. The opalescent crystals range in size from 1/4 inch to l inch and make up 3 to 5 percent of the rock by volume.
The owner hopes to select fresh rock material suitable for cutting and polishing. -65 -
