Biographical Note
Roger Stern was born September 17, 1915 in New York, New York and raised
in California. He attended schools in Glendale and graduated from San Diego
State University in 1938 with a B.S. in Physics. He served in the U.S. Navy in
the field of Aviation Electronics from December 1944 to March 1946. Roger Stern
married Caroline Vota Stern; they had 3 children.
His extensive career in the mineral industry spanned more than 40 years;
he worked mainly in Mexico. From 1937 to 1941, he began as an
assayer-metallurgist and superintendent at the El Fenomeno Mine in Ensenada,
Baja California. From 1941 until 1955, Stern worked for American Smelting and
Refining Company (ASARCO) in various lead-zinc operations in Mexico, including
positions in ore testing, metallurgical accounting, and management.
In 1955, Stern resigned from ASARCO to accept the position of Chief
Metallurgist with Cananea Consolidated Copper Company in Sonora, Mexico, also
known as Compañia Minera de Cananea. During his twenty-two years with
the company, he held various positions, and retired on September 30, 1977, as
Assistant General Manager. Following his retirement, Stern acted as a
consultant for Pincock, Allen and Holt, a mining industry consulting company in
Tucson, Arizona. His expertise was in the fields of mineral dressing,
flotation, crushing, copper smelting, and fire refining.

materials, 1955-1978, relating chiefly to his career as an engineer and manager
at Compañia Minera de Cananea in Sonora, Mexico, and as a consultant
with the firm Pincock, Allen and Holt in Tucson, Arizona.
The majority of the alphabetically arranged files reflect topics
concerning copper mining operations in Cananea, Mexico. Each file may contain
correspondence, memorandum, research notes, blueprints, or printed materials
from administrators, researchers, or suppliers to Stern relating to various
processes and products in the mine. The major departments of the mine were Open
Pit Mining, Concentrator, Leaching and Precipitation, and Smelting; support
facilities included power genera-tion, shops, and railroad.
The largest files are: Cananea Reports, which contain documents on
particular phases of the operation; Field Trips and Other Operations, which
were written by Stern and other engineers in the 1950s and 1960s and detail
visits or studies of related mining ventures, mainly in Arizona; Pincock, Allen
& Holt, which contain his consulting activities during the late 1970s; and
Supplementary Printed Materials, which hold brochures, equipment catalogs, and
similar information on a wide variety of mining topics. Of interest in this
folder is his copy of
Contrato Colectivo y Reglamento Interior de
Trabajo (Cananea, 1975) concerning labor and management relations at
the mine.
