Created in 1 8 49 , the Department of the Interior-- A m erica's D e partment of Natural Resources-- is concerned with the management, conservation, and development of the Nation's water, wildlife, mineral, forest, and park a n d recreational resources. It also has major re sponsibilities for Indian and Territorial affairs.
A s the N a tio n 's principal conservation agency, the Department works to assure that nonrenewable resources are developed and used wisely, that park a n d recreational resources are conserved for the future, and that renewable resources make their full contribution to the progress, prosperity, and security of the United States-- now and in the future.

FOREWORD
MINERALS YEARBOOK, 1962, published in three volumes, pro vides a record of performance of the Nation's mineral industries during the year, with enough background information to interpret the year's developments.
Tne three-volume issues of the Yearbook follow this pattern: Volume I includes chapters on metal and nonmetal mineral com modities except mineral fuels. In addition, it contains a chapter reviewing these mineral industries, a statistical summary, and chap ters on mining and metallurgical technology, employment and in juries, and technologic trends. The former "Minor Metals" and "Minor Nonmetals" chapters have been combined in one chapter on "Minor Metals and Minerals." Volume I I includes chapters on each mineral fuel and a helium, an employment and injuries presentation, and a mineral-fuels review chapter that summarizes development in the fuel industries. Volume I I I contains chapters covering each of the 50 States, plus a chapter on island possessions in the Pacific Ocean, the Common wealth of Puerto Rico and island possessions in the Caribbean Sea, including the Canal Zone. Volume I I I also has a statistical sum mary chapter, identical with that in Volume I, and a chapter on em ployment and injuries. Figures in the Minerals Yearbook are based largely upon infor mation supplied by mineral producers, processors, and users, and acknowledgment is made of this indispensable cooperation given by industry. Information obtained from individuals through confiden tial surveys has been grouped to provide statistical aggregates. Data on individual producers are presented only if available from published or other nonconfidential sources, or when permission of the individuals concerned has been granted.

A LTH O U G H the United States consumed 24 percent oi the world output of asbestos fiber, it supplied only 7 percent of its own
" * requirements. The Nation ranked seventh among world pro ducers and contributed 2 percent of the total output.
LEGISLATION A N D GO VERNM ENT PROGRAMS
A revised national stockpile purchase specification, P-4-R3, was issued on January 23, 1962, by the Office of Emergency Planning for Government procurement of amosite asbestos. The new specifica tion superseded the one dated August 4, 1959.
Deliveries of Arizona No. 2 chrysotile for the stockpile were com pleted by one of three contracting operators. The Government con tinued to acquire amosite and crocidolite asbestos for stockpiling under barter agreements through the U.S. Department of Agriculture.

Imports of amosite and chrysotile increased 36 and 9 percent, respec tively, and crocidolite decreased 4 percent, resulting in an overall in crease of 9 percent in total asbestos imports in 1962.
Low-iron chrysotile imports of spinning-length fibers from British Columbia decreased from 5,374 tons in 1961 to 5,077 tons. Ninetyseven percent of all chrysotile imported was short fiber of less than spinning length.
The Kepublic of South Africa supplied crocidolite and chrysotile and was the only source of amosite. Imports from Australia consisted solely of crocidolite. The total of crocidolite imports from these two countries was 17,127 tons. An additional ton was imported from Bolivia. Finland supplied anthophyllite, and only chrysotile was imported from other countries.
Exports of unmanufactured asbestos decreased from 3,572 tons in 1961 to 2,824 tons.
Imports included 7,633 tons of amosite and 8,270 tons of crocidolite acquired for the Government's supplemental stockpile.*

WORLD REVIEW B
NORTH AMERICA
Canada.--Asbestos shipments in 1962 set a record of more than 1.2 million tons. More than 95 percent of 1961 shipments were exported.8 Employment at Canadian asbestos mines and mills in 1961 totaled 6,875 workers.
Canadian Johns-Manville Co., Ltd., operated the Jeffrey mine. Asbestos, Quebec, close to capacity during 1962. The return of the mine to open-pit operation was essentially completed. An inclined skipway was installed for removing waste from the pit. Explorations for asbestos were conducted by the company between Amos and Barraute in northwestern Quebec. The company managed development operations at the Advocate Mines, Ltd. property, Baie Verte, northern Newfoundland, where stripping of waste continued in preparation for production to start in mid-1963. Output was expected to exceed 40,000 tons of fiber annually, mainly group 4 for use in asbestoscement products.
Asbestos Corporation Ltd. exchanged shares equivalent to a 10-per cent interest with Eternit S.A. of Belgium. A long-term contract for purchase of asbestos from the Canadian company was included in the agreement. Ore reserves at the end of 1962 were, in million tons: King-Beaver, 12.4; British Canadian, 46.9; Normandie, 20.3; and others, 14.2. A total of 4.6 million tons of ore was milled, and 10.9 million tons of barren rock excavated. More than 1 million tons of overlying waste, was stripped from the ore hody at the Normandie mine. A pilot plant for producing finely ground asbestos filler was installed at the mine.
An option was taken by Asbestos Corporation Ltd. on the Murray Mining Corp. Ltd., Asbestos Hill property, south of Deception Bay in the Ungava area, northern Quebec. Exploration and plans for de 1 ment continued.
action by Lake Asbestos of Quebec Ltd., a subsidiary of Ameri can Smelting and Refining Company, totaled 100,612 tons, compared with 95,042 tons in 1961. Ore reserves were increased at the com pany's Black Lake, Quebec, mine by continued development work on the open pit.
Several exploration holes were drilled by Bornite Copper Corp. on its prospect m Cleveland Township, near Asbestos, Quebec. A de posit 1,000 feet or more long and 140 feet wide was indicated. Assays were from 6.4 to 9.7 percent fiber and floats, mainly classified as shorts. A magnetometer survey was completed over the northeast part of the
Gypsum Co. initiated an expansion program to increase capacity at its Thetford Mines, Quebec, property.

A t Roberge Lake, northwestern Quebec, McAdam Mining Corp. drilled a 500-foot hole to explore a magnetic anomaly northeast of the main asbestos zone. The main zone was reported to contain 15 million tons of ore averaging about $5 per ton in fiber value. A third zone was
indicated by a magnetometer survey. Central Asbestos Mines con ducted magnetometer surveys of claims in the Thetford Mines area and Coleraine Township, Quebec. Recoveries from bulk tests in the pilot plant at the Hedman Mines Ltd. property in W arden and Munro Townships, 25 miles northeast of Matneson, Ontario, averaged about $25.50 per ton in value. Reserves available through open-pit mining
to a depth of 300 feet were estimated at 8.5 million tons. Design of a large mill was nearly completed.
The main shaft at the Munro mine of Canadian Johns-Manville Co., Ltd., was deepened 300 feet below the 637-foot level in prepara tion for a second production level. W ork continued on the westward extension of the 637-foot level. Two grades of fiber were produced.
Operations at the Cassiar Asbestos Corp. Ltd. mine in British Co lumbia continued through the winter months. During 1962 720,000 tons of ore was mined and 2,358,000 tons of waste rock stripped. Ore milled totaled 535,000 tons, consisting of 295,000 tons of concentrate from the rock-rejection circuit and 240,000 tons of mine-run ore. Plans were made to move the crushing plant to a lower level and to install a larger crusher. Recovery of AK and A X grades was to be improved. Ore reserves were sufficient for 30 years of production at the current rate. The parent company, Conwest Exploration Co., Ltd., leased w aterfront property in North Vancouver, British Colum
bia, and planned a $1 million improvement in dock facilities. An option on an asbestos prospect southeast of A tlin on the Taku River,
British Columbia, was dropped.

zilian ports totaled 1,279 tons in 1962. A pilot plant reportedly was constructed for processing fiber from newly discovered deposits in Batalha, Alagoes.
EUROPE
Greece.--Developmental work was continued on an extensive deposit of asbestos at Kozani by Kenbestos Corp., a subsidiary of Kennecott Copper Corp. A plant to produce asbestos-cement products was planned.
Ireland.--Exploratory drilling of a deposit near Sligo on the north west coast was planned by Northern Canada Mines, Ltd.
United Kingdom.--A $3 million asbestos-cement-products plant, the largest in Europe, was opened at Widnes in northwest England.
Yugoslavia.--An established plant, Antisa Vucicic Salonite, began producing large-diameter asbestos-cement pipe partly for export. An asbestos-yam plant began operating at Poloce on the Adriatic. Means for improving the mining and processing of asbestos were studied by an American, Dr. A rthur B. Cummins, under an International Cooperative Administration contract.
ASIA
Cyprus.--All production was exported, except for a few hundred tons that was used annually for domestic manufacture of asbestos-cement sheeting. Reserves at the Cyprus Asbestos Mines, Ltd., deposit below the summit of Mount Olympus near Amiandos were large, but the fiber content was generally less than 1 percent.
India.--ImporLs of asbestos totaled 21,679 tons valued at $4,935,000 in 1961, compared with 24,315 tons valued at $5,670,000 in 1960. Domestic asbestos was a suitable substitute for imported fiber in the manufacture asbestos-cement pipe in a process developed by Central Fuel Research Institute.7
Viet-Nam.--Plans were announced by E tem it Vietnam for an asbestos-cement plant at Saigon having an annual capacity of 10,000 tons.
AFRICA
Bechuanaland.--Exports totaled 1,852 tons valued at $450,527 in 1961. An aerial magnetometer survey was conducted, mainly over southern portions of the territory, in search of asbestos and other
m inerals.
Mozambique.--Long-fiber tremolite was produced from the Mavita mine of Sociedade Mineira de Mavita, Lda., south of Vila Manica near the Rhodesian border, and exported to several countries including the United States for asbestos-cement manufacture.
Rhodesia and Nyasaland, Federation of.--Crude asbestos exports, mostly from Turner and Newall, Ltd., mines at Shabani and Mashaba, to taled 133,516 tons valued at $23,637,000 in 1961. The tonnages were distributed as follows, in percent: United Kingdom, 57; Czechoslo vakia, 8; Poland, 2; United States, 1; and other countries, 32. As-
