One of his responsibilities was “the duty of collecting information on the subject of the mining industries of the Province.” This material, which consisted of reports by the Gold Commissioners and Mining Recorders ofthe Province, was published inthe Annual Report of the Minister of Mines. A Bureau of Mines was established by Parliamentary authority in 1895 and in 1896 was staffed by a Provincial Mineralogist and anassayer and chemist.Technical reports on mines and mining activities were prepared by them and published in the Annual Report, together with reports contributed by the MiningRecorders and Gold Commissioners. Over the years with the expansion of the mining industry, the staff of the Department of Mines grew, as did the number and size of the technical reports on geology and mining that were still published in the Annual Report of the Minister of Mines, Over a period of nearly 75 years the Annual Report became known as the authoritative record of mining in the Province. However, in 1969 because of the size to which the Annual Report had grown, it was decided to publish all geological and technicalreports dealing with solidminerals in a separate volume entitled Geology, Exploration and Mining in British Columbia. Thus a new annual publication was initiated with chapters on exploration and mining related to metals (Chapter 2). placer(Chapter 3). structural materials and industrial minerals (Chapter 4). and coal (Chapter 5). SOLID MINERALPRODUCTION IN 1974 The value of solid minerals, that is, metals, industrial minerals and structural materials, and coal, exceeded a billion dollars for the first time. This value was $1,030,883,091 in 5 m TABLE 1.

The chief cause of this continuing upward movement in the value of solid mineral production in British Columbia in the face of generally sagging metal prices and world-wide recession was the considerable increase inthe quantity and value of metallurgical-grade coal produced. However, metals form the major component of productionat $764,524,841 or 74.1 per cent of the total, in contrast to coal at 5154,593,643 or 15 per cent, structural materials at $78,088,393 or 7.6 per cent, and industrial minerals at $33,676,214 or 3.3 per cent. Table 1 also includes, for the first time, the quantities of metals paid for to the mines, excluding outward transportation and smelting and refining costs. The significantly lower value to the mines of metal produced is illustrated particularly by copper where the value produced was $541,644,913 but the value paid for was$440.490.965. Copper is still the most important metal produced, representing 52.5 per cent of the total value of all mineral production, although production was down 66 million pounds from 1973. The demand for molybdenum remained strong during the year with the quantity of 30.4 million pounds of contained molybdenum being slightly higher than the 1973total, Values received for the molybdenum in thesulphides, oxides, and ferromolybdenum were all higher in1974 and totalled $60.7 million compared to $51.9 millionin 1973, an increase of 17 per cent. The quantities of lead and zinc produced were significantly down, chiefly as a result of the prolonged strike at the Trail smelter of Cominco Ltd. but, with anincrease in the average price during the year, the value was not as severely affected. The value of zinc production was $59,582,753 versus $62,564,751 in1973 and the value of leadwas $23.333.01 6 versus $30,477,936 in 1973. The strong demand for coking coal resulted in anincrease in production of 12 per cent from 7,633,651 tons to 8,551.159 tons which, with the significant increase in unit value, resulted in the considerable increase in value of 75.7 per cent or from $87,976,105 to $154,593,643. These five commodities, copper, molybdenum, zinc, lead,and coal, represent 81.5per cent of the total value of solid mineral production. Other commodities, with production in 1974 valued over 10 million dollars, include gold, iron, silver,asbestos, cement, and sand and gravel.

The value of British Columbia mineral production in 1947 was more than $113,000,000, a record which far exceeds the value of production in any preceding year. Many factors contributed toward the record value, but by far the most impor- tant was the high price for most products. The price of gold we.9 lower than for any year since 1937, the price of silver, although high, was somewhat lower than the 1946 price, but the price for copper was the highest for any year since 1918, the price for lead exceeded substantially the price in any preceding year, and the price for zinc was much higher than for any year except 1915 and 1916.

  • Skeena River Showing the Known Dis• Tribution of Rocky Mountain ( ) and Eastern Whitefish (#) 7 Fig
    6,1,-tSn A STUDY OF LIMNOLOGICAL CONDITIONS OF SKEENA LAKES AS THEY AFFECT THE DISTRIBUTION AND ABUNDANCE OF THE 1HITEFISHES COREGONUS AND PROSOPIUM By Harold Godfrey A Thesis submitted in Partial Fulfilment of the Requirements for the Degree of MASTER OF ARTS in the Department of ZOOLOGY THE UNIVERSITY OF BRITISH COLUMBIA April, 1949. ii ABSTRACT Limnological conditions in lakes of the Skeena drainage, British Columbia,have been examined to asoertain what factors may be restricting the distribution and/or abundance of the Eastern and Rooky Mountain whitefishes. The Eastern whitefish is known to be in only four Skeena lakes, and the Rooky. Mountain whitefish in all Skeena lakes which have been investigated. It is probable that the Eastern whitefish has not entered other Skeena lakes because the lake conditions are not suitable for its establishment. Such conditions are mainly warm waters, shallow depths, and small area; and are sometimes the heavy silting of the water, and the resultant poor food supply. It is not numerous in any of the four lakes, probably because of the relative poor abundance of bottom food organisms, particularly in the absence of such organisms as the amphipod Ppntoporeia. Conditions are apparently most favourable for Eastern whitefish in oligotrophia lakes. Rocky Mountain whitefish appear to favour eutrophic lakes, and are most abundant in lakes where a good supply of bottom food is assured by the absence of such potential competitors as the Peamouth chub and Squawfish. There is no evidence of any heavy predation on either of the two whitefish. It is improbable that any physioal barrier has limited the distribution of these fish.

  • Landforms of British Columbia 1976
    Landforms of British Columbia A Physiographic Outline bY Bulletin 48 Stuart S. Holland 1976 FOREWORD British Columbia has more variety in its climate and scenery than any other Province of Canada. The mildness and wetness of the southern coast is in sharp contrast with the extreme dryness of the desert areas in the interior and the harshness of subarctic conditions in the northernmost parts. Moreover, in every part, climate and vegetation vary with altitude and to a lesser extent with configuration of the land. Although the Province includes almost a thousand-mile length of one of the world’s greatest mountain chains, that which borders the north Pacitic Ocean, it is not all mountainous but contains a variety of lowlands and intermontane areas. Because of the abundance of mountains, and because of its short history of settlement, a good deal of British Columbia is almost uninhabited and almost unknown. However, the concept of accessibility has changed profoundly in the past 20 years, owing largely to the use of aircraft and particularly the helicopter. There is now complete coverage by air photography, and by far the largest part of the Province has been mapped topographically and geologically. In the same period of time the highways have been very greatly improved, and the secondary roads are much more numerous. The averagecitizen is much more aware of his Province, but, although knowledge has greatly improved with access,many misconceptions remain on the part of the general public as to the precise meaning even of such names as Cascade Mountains, Fraser Plateau, and many others.
