WORLD REVIEW 
 A private firm of marketing consultants, C. H. Kline & Co., of Fairfield,
N.J., scheduled for completion in late 1972 two new surveys of the current
and projected marketing situation, both domestic and international, of a
number of filler and extender pigments, among which talc is a prominent example.
The announced objective of the first study was a review of new developments
and future trends in the U.S. market for those commodities; that of the second
was an analysis of the factors and sometimes complex interrelationships affecting
that market in parts of Europe, specifically Spain and the countries of the
European Economic Community and the European Free Trade Association. 
 Australia.—Talc reserves at the Seabrook deposit near Meekatharra,
West Australia, property of Westside Minerals, N.L., were estimated at 1
to 2 million tons of 76% ore easily extractable by selective open pit methods.
Preparations were made to begin mining at an initial rate of 100,000 tons
per year, and plans were revealed to process the output in a milling plant
to be constructed especially for that purpose at the Indian Ocean port of
Perth. Australia's 
total annual production of talc has ranged in recent years from less than
20,000 tons to over 140,000 tons. 
 Brazil.—Although no official quantitative data are published, Brazil
has a substantial yearly output of talc and soapstone, mostly from Paraná
and Minas Gerais, while lesser quantities are mined in Rio de Janeiro, Sflo
Paulo, and Bahia. There is a significant export trade in talc, and a growing
cottage industry utilizes important quantities of soapstone in the production
of hand-carved art objects. 
 Canada.—Three companies produce talc in Canada, one in Ontario and
two in Quebec. The leader, Baker Talc Ltd., with properties near South Bolton,
Quebec, has developed beneficiation procedures for upgrading its talc product
to paint and paper grade; that process, involving both froth flotation and
high-intensity wet magnetic separation, was placed in limitedscale operation
in 1970 and went to fullscale in 1972. 
 Pyrophyllite was found to make up the bulk of an intrusive body of relatively
recent geological age at the west end of the working pit of the newly developed
Island
