were found for only about half of this amount it was considered doubtful
if mining activities would be resumed in 1966.12 Liniestone.—Chilean
limestone production declined slightly from that of 1964. Cemento Cerro Blanco
de Polpaico, S.A., reported a production of 791,045 tons during 1965, and
Empresas Industriales El Melon, S.A., reported 611,663 tons, for use in their
respective cement manufacturing plants. Most of the remainder came from the
Cuarello Island properties of CIa. de Acero del Pacifico S.A. for the company's
iron and steel complex at Huachipato.13 
 Salt.—Chilean salt production reportedly increased 6 percent over
the previous year's total. Cia. Sal-Chile, a new company that has acquired
the properties of Salinas Punta de Lobos, was planning to expand production
from its deposits in the Salar Grande area south of Iquique, in the Province
of Tarapacá. Chilean salt needs are estimated at 80,000 tons per year.
About half were supplied by Sal-Chile, while the remainder came from Leandro
Antonijevic Ltda. and Fistonic, Kinast y CIa., operating in the same area.14
 Sodium Sulfate.—Chilean sodium sulfate production for 1965 increased
84 percent over the 1964 figure. Most of the production came from the properties
of Sociedad Minera Canchones Ltda. near Iquique, with the bulk of the remainder
supplied by Sr. Hector Rojas A., who reported a 1965 production of 1,300
tons of 87 percent sodium sulfate and 3,300 tons of 84 percent.'5 
 Sulfur.—Chilean sulfur production declined about 23 percent from that
of 1964. The country's largest producer, Sociedad Azufrera Aucanquilcha S.A.,
reduced production from 33,350 tons in 1964 to 28,034 tons in 1965. It was
reported that Mauricio Hochschild y CIa. S.A.I.C. and associated companies
had purchased additional shares in the Aucanquilcha Corporation during the
year. This was to assure an adequate amount of sulfuric acid for the copper
treating facilities of Cia. Minera Mantos Blancos.16 
 In addition to Chile's mined sulfur, the 
Chile Exploration Co. and the Braden 
Copper Co. each recovered approximately 
half of an estimated 10,635 tons of sulfur 
(sulfur content of acid) from smelter gases 
 Coal and Coke.—Gross Chilean coal production was slightly lower than
that of 1964. Carbonifera Lota-Schwager S.A., in producing 1,293,661 tons,
retained its traditional share of total Chilean output. Production for 1965

 An estimate of coal consumption by major consumer groups for 1965 follows:

Cement plants 160

 Total 1,679 
 The Lota-Schwager operation continued to show losses in spite of an intensive
modernization program. High mining costs were attributed to the depth of
the coal seams, their distance from the mine shafts, and the costs of wages,
salaries, and benefits. The company indicated that personnel has been reduced
approximately 40 percent in the past 10 years, from 15,600 persons in 1955
to 9,300 in 1965.
