The chief mines of these districts are now controlled by American capital and may be classed with group 2 of Table 38. The Morococha district was formerly English controlled, but the majority interests have lately been acquired by the Cerro de Pasco Copper Co. (American). The ores in both districts are exceedingly rich and the properties are well fortified with reserves. Developed reserves are adequate to insure four years’ production, and everything indicates that the mines are working extensive and persistent ore deposits. Blister copper is shipped to the American Smelting & Refining Co. in New York for treatment and marketing. Both mines have fully equipped plants, including smelters. At the plant of Backus & Johnson Co., Morococha, some custom ore and matte from locally owned mines is treated. Among these mines are those of J. Galliver, producing 600 tons matte a year. Backus & Johnson also have a smelter and mines in the Casapalca district. The Sayapullo Syndicate (English) is working the Sayapullo mine under option from the Peruvian owners. Some of this matte is shipped to the Casapalca smelter, and the rest is exported to the United States. The output so far is small; at present 800 tons per year. Certain small companies ship ores to the United States: from these the copper content amounted to about 4,000,000 pounds in 1917. This goes (1919) chiefly to the American Metal Co. and L. Vogelstein for refining and selling. This ore comes from Salaverry and Trujillo (Casapalca district), Mollendo (southern district, including Ferrobamba, see below), and Callao. All the blister copper is shipped from Callao except small amounts shipped by Backus & Johnson from the Casapalca district. An American company has developed a large body of low-grade ore at Ferrobamba (Cotobamba Province), southern Peru. The property is inaccessible and no work is now being done. The following résumé gives some of the salient facts concerning the Peruvian copper producers: TABLE 44.--PRODUCTION OF COPPER IN PERU IN 1918 ----------------+--------------+---------+--------------+------------- | |Developed| | | Output | Reserves| Product | Control ----------------+--------------+---------+--------------+------------- Cerro de Pasco | 72,000,000(-)| 4 years |Blister Copper|United States Backus & Johnson| 28,000,000(-)| 4 years | Do | Do Huaron (new) | 5,000,000(?)| 4 years | Do |French Ore shippers | 5,000,000 | ? |Ore |Local +--------------+ | | |110,000,000 | | | ----------------+--------------+---------+--------------+------------- BOLIVIA
