=Mexico.=--Mexico has important deposits of iron ore in the States of Lower California, Coahuila, Durango, Guerrero, Michoacan, and Oaxaca. The largest iron and steel making plant in Mexico is that of the Compañia de Aciero y Fierro de Monterey, State of Nuevo Leon, operated by Spanish capital. This plant produces between 50,000 and 100,000 tons of pig iron yearly. Ore is obtained from Coahuila, and coke from nearby coal fields. At Durango is a charcoal furnace, which has been idle for many years. It is owned by the Durango Iron & Steel Co. (American). Small iron-making operations exist in Hidalgo, Puebla, Vera Cruz and Oaxaca. The best known of the Mexican iron-ore deposits is that of Iron Mountain (Cerro de Mercado), near Durango City, a large body of magnetite. In Lower California there are important deposits of iron ore at several localities. They are owned by the International Development Co., an American firm with headquarters at Los Angeles, California. The deposits in Guerrero, Michoacan and Oaxaca are reported to be extensive. =South Africa.=--Various deposits of low-grade iron ore are found in South Africa. In Transvaal there is siliceous sedimentary hematite and magnetite in ferruginous schists of different ages, titaniferous magnetite associated with basic igneous rocks, and local clay-band ore; and in both Cape Colony and Transvaal there are lateritic surface ores. A 15-ton blast furnace has been built within the last year or two near Pretoria by the Pretoria Iron Mines Co., Ltd., for the purpose of manufacturing pig iron from local ores. This is the first attempt to establish an iron industry in South Africa. =Australia, Tasmania, and New Zealand.=--In Australia and New Zealand are some important iron-ore deposits, but only a few are developed. Most of the iron ore mined in Australia has been used for flux in copper, lead, zinc, and other smelting plants; a small amount has been used in the two local iron and steel works--that of the Broken Hill Proprietary Co., at Newcastle, New South Wales, and that of the Eskbank Iron Works at Lithgow, about 75 miles west of Sydney, New South Wales. The former is the more important, having in operation at the present time two blast furnaces as well as steel furnaces, rail mill, and plate mill.
