Historical Note

El Potosí Mining Company conducted mining operations at Santo Domingo, located in the Santa Eulalia district of the Mexican state of Chihuahua. Forerunners of the company established a presence in the area in 1881; by 1901 the company was known as El Potosí Mining Co. It maintained offices in Chihuahua and in El Paso, Texas. El Potosí Mining Co. and its affiliate, the Compañía Industrial “El Potosí”, S.A., were subsidiaries of the Howe Sound Company and were affiliated with the Britannia Mining and Smelting Co., Ltd., of British Columbia, Canada.

Scope and Contents

Reports, correspondence, blueprints and drawings, and photographs reflecting the business operations in Mexico (1929-1942) of El Potosí Mining Company. Annual reports cover both El Potosí Mining Company and Cía. Industrial “El Potosí”, S.A. for the years 1931-1939, with the exception of 1937. These form the bulk of the records. Other reports include a 1934 U.S. Bureau of Mines publication by Harlan A. Walker, mine superintendent, entitled Mining methods and costs at El Potosí Mine; a report on the Carmen Mine in Chihuahua (includes 21 photographs); and reports (1952 and undated) pertaining to properties in Venezuela. The latter describe prospects for gold mining in the Amacuro Delta of Venezuela and contain descriptions of the area's geology and geography.

Correspondence (bulk dates 1929-1937) relates largely to the activities of C. V. Brennan, who was Chief Engineer for the Exploration Department of Britannia Mining and Smelting Co., Ltd. and later became Assistant General Manager of the Howe Sound Company. Letters from F. C. Kilpatrick, Agent in El Paso, Texas, for El Potosí Mining Co., explain company procedures and are accompanied by many of the company's business forms. Other officials or employees of the company and its affiliates who are represented in the correspondence include E. P. Ryan, general manager of the Howe subsidiaries in Mexico; H. H. Sharp, Vice-president, Howe Sound Co.; and Harlan A. Walker. Two items from 1951 and 1952 concern the prospects of gold mining operations in Venezuela. Blueprints and drawings primarily depict facilities of El Potosí Mining Company and the Carmen Mine.

The materials are in English.



The papers are organized in three series:
1. Reports
2. Correspondence
3. Blueprints and drawings
