 Harshaw district —Zinc-lead-silver ore from the Trench and Flux groups
was by far the principal output in the Harshaw district in 1941 The American
Smeltmg & Refining Co operated both groups and its 200-ton concentrator
continuously, about 67,300 tons of ore were treated in 1941 compared with
49,311 tons m 1940 The company was again the largest producer of lead in
Arizona and ranked second in zinc The remainder of the district output was
chiefly crude silver ore from the American, Salvador, and World's Fair properties
 Nogales (Gold Hill) district —Nearly all the output of the Nogales
district in 1941 was gold-silver ore from the Roy mine and gold ore from
the Louella Lou, Hardscrabble, and Silent Friend properties
 Oro Blanco district (Ruby) —Production in the Oro Blanco district
in 1941 was 1,411 tons of ore, a marked declme from 54,564 tons in 1940 This
large loss resulted from suspension of operations at the Montana zinc-lead-silver
property in May 1940 The district output m 1941 was largely gold-silver ore
from the Old Soldier and Noon properties, silver ore from the Brick claim,
and gold ore from the Oro Blanco mine

R mine were concentrated, and a small lot of crude silver-lead ore from the
La Palma claim was sold to a local ore buyer
 Patagonia (Duquesne) district —The increased output of silver, copper,
lead, and zinc in the Patagoma district in 1941 resulted from continuous
mining and milling operations at the Duquesne property by the Callahan Zinc-Lead
Co The company reported that 27,572 wet tons of zinc-lead-copper ore were
treated by flotation in 1941 and that 1,109 tons of silver-lead-copper concentrates
and 696 tons of copper concentrates were shipped to El Paso, Tex., and 3,601
tons of zinc concentrates to Amarillo, Tex. The rest of the district output
