Canada continues to be largest producer and exporter of asbestos in the world with sales in 1973 of 1.8 million 1.tons Production & Developments The Province of Quebec produced over 1.5 million tons The purchase of National Asbestos 60,000 tons annually by Lake Asbestos of Quebec Ltd. 150,000 tons annually makes them the third largest of the five main producers by sales value after Asbestos Corporation Limited 360 000 tons annually and Canadian Johns Manville Manville with ore reserves of over 500 million tons and an annual production of over 600,000 tons mainly in groups 4-7 have invested 75 million in an advanced mining and milling complex which is geared to long term recovery and expansion This development includes one of the world's largest ore crushers designed for a feed of 3,000 hour of are Asbestos Corporation Limited have built a new crushing station 1,400ft underground at their King Beaver mine At their Asbestos Hill mine in Ungava Northern Quebec production appears to be on schedule and shipments of concen- trate were made to their Nordenham West .. Germany Mill in the short free shipping season The Nordenham fibres are particularly suitable for the manu- facture of asbestos cement pressure pipes The Bell Mine 50,000 year capacity owned by Turner & Newall Limited completed the sinking of their new 1,450ft shaft with a corresponding production increase in 1973 Canadian continues to produce nearly a quarter of a million tons of mainly short white fibres which are particularly in demand by the floor tile - industry and other outlets where fibre colour is important There are several new developments under way in Quebec including Abitibi at Maizerets Township near Amos whose pilot plant is now operational and production is expected to commence in 1976 with a capacity of up to 150,000 ton year McAdant Mining's property at Chibouga man is making progress and samples are being distributed for customer testing Celtic Minerals Limited are proposing to a investigate property at Cleveland Town- HD 100 miles south of Montreal The Newfoundland Advocate Mine combined Manville Eternit Groups and Patino operation operate at near capacity 75,000 tons Production in Ontario is at present limited to Johm Manville's Reeves Mine at Matheson Timins 25,000 tons but new deposits being developed investigated or near include United Asbestos Inc. formerly Allied Mining which has spent 2.5 million on its property at Midlothian Township 40 miles south of Timmins production is due to commence in 1975 with a rill capacity of 160 ton year In Western Canadia Creek produse ever Cassiar Mountains BC and the Yukon territory and they are exploring other * these deposits in areas In the Yukon American Smelting and Refining owners of Lake Asbestos of Quebec are diamond drilling on the Rex asbestos property The Alaskan highway originally opened up these areas for developmen and the present expansion of railway facilities north from Vancouver could increase the potential importance of the area The Quebec Asbestos producers advised two price increases during 1973-8 in May and 15 effective 1st January 1974. A Further increase of 10 in April 1974 was announced recently Production of asbestos in the U.S. is Small 150.000 tons mainly consisting of in short libre The major producers Vermont Arizona and California ' Gremolite deposit is being investigated in Texas : Asbestos production figures from Rhodesia arc classified information according to the Rhodesian Government Rhodesian but despite sanctions Rhodesian asbestos is still being sold in many countries It is reasonable to assume that production con- tinues at less than 150.000 tons year In Cyprus production continued at a levet similar to previous years Italian production at the Balengeru Mines which is part owned by the International Eternit amounted Group approximately 135,000 tons mainly in the shorter grades Woodsreef The mine continued to operate but the million mining and milling facilities at Barraba N.S.W. have been receiver under the direction of a appointed by the Commercial Bank of Australia Woodsreef has stressed though that what is in view is a further determina- tion of the viability of the operation and future financing needs and not a move towards liquidation Even so the appreciable promise of the asbestos occurrences in Australia have still to be proved It is always difbcult to production of known that resources in prepun they have the largest world From figures in Soviet Export A.

Korolev it would appear that their million tons 85 toal production is over million from the Urals area there is also an important chrysotile mine Kazakhstan The United States Bureau of Mines however estimate that by 1975 the Russian production will only be 1.45 million ten year The world's Largest consrimers nf asbestos are the US and the G.S.S K. and the majority of the Russian produci^n produci^n used within the U.S.S.R. althqueh important quantities are exported to the Comecon countries and to niher countries . with trading agreements with the U.S.S.R. production South African includes all three of the main commercial types of Chrysotile 70,000 tons Crocid- olite Blue 1601 tons and Amosite 120,000 tons The Cape Asbestos Com- pany are the largest producer of Amosite in the world 100,000 metric tons Amosite asbestos does not necessarily compete with other types of asbestos since it is used particularly in the manufacture of light weight fire resistant insulation boards refractory tiles f^,rsteel foundries hot tops and high temperature insulation products such as calcium silicate and moulded asbestos Amosite is often - used in conjunction with Chrysotile for the manufacture of asbestos products : Blue asbestos is now used mainly in the locked in applications such as the manufacture of asbestos asbestos as 83 PRODUCE including asbestos pressure pipes asbestos which are using a high percentage - of the present Blue asbestos production Demand The continuing demand for is demand asbestos reflected in the number of deposits being investigated and evaluated all over the world Apart from those mentioned above new deposits are being examined for com- mercial exploration in China Bolivia Columbia Mexico Tasmania New Zea- land and Greece : . The demand for asbestos from the Industrialised countries of the world con- tinues strong but with a smaller growth rate projected than for other areas In devloping areas the growth rate is particularly high in The asbestos industry The comparatively low cost of advantages asbestos advantages cement sheets rat- vermin as well as flammable make it an invaluable aid to low cost housing and industrial development in these areas There is also a strong demand { pressure pipes which make an indefinite working life for water supply and in- creasingly for sewerage disposal Progres- sively larger dister asbestos pipes up to 229 metres internal diameter are being produced to contain all services For example to protect gas electric drainage and water supplies all housed within a main conduit through which service engin- eer can easily pass Health In many quarters there is still considerable concern expressed regarding_matters regarding_matters of health and asbestos which continues to receive attention from the press Much work has been done to currect misleading information which appears from time to Asbestos time on this subject The U.K. Information Cominitiee up in 1967- has contributed much to a better under- standing of asbestos and its relation to health problems In addition the AIC has been instrumental in assisting in the setung up of similar bodies in Europe and the U.S.A. Like so many other industrial minerals asbestos has no health hazard _ which cannot be readily controlled it correctly used Outlook So far as the world outlook for 1974 is concerned the market at present continues to evidence very high demand compared with availability and there is no immediate evidence of a slackening in demand Both the U.S. and Japan are large consumers of asbestos and any big recession affecting the building industries in these countries could have the effect of bringing down demand more in line with supply PRODUCTION OF ASBESTOS Australia Brazil wn Canada Cyprus vee China ae Finland wes - Italy oo Rhodesia South Africa Swaziland .., U.S.A. ** U.S.S.R. 44 Others ae 1971 09 22 16347 26-8 180 114 131 100 350-6 39 132 1265 46-6 1972 25 33 1692 291 190 12 135 120 350 33.5+ 135 1350 47 1973 20 33 1863 31 190 10 135 120 350 151 35 151 450 52 * 3941 4445-5 4440 ert Fluure amended from table in 4 Annual Review 1973 * estimitated Canadian production CSae nut da Ruy production Stinel estimated 1973 Mining _ Staisti~N by Statisti~N by the U.S. A.F.I.C A.F.I.C JM Manville Internal Correspondence E.
