 Ores and gravels from mines in Washington yielded gold, silver, copper,
lead, and zinc valued at $7,874,886 in 1941 compared with $7,018,812 in 1940
The output of each metal except copper increased The gain in value Of total
output was due chiefly to greater production of lead and zinc, which was
stimulated by the urgent need for these metals. Gold and silver production
improved owing to a sharp rise in output from the Republic district, Ferry
County, which more than balanced losses in the Methow district in Okanogan
County and by the Howe Sound Co. in the Chelan Lake district, Chelan County.
The bulk of the State copper production came from the Holden property of
the Howe Sound Co. The decline from the 1940 output of copper can be ascribed
to the lower grade of ore treated. The production of lead and zinc, which
was derived chiefly from ores mined in Pend Oreille County, gained sharply
over 1940 due principally to full-year operation of the properties of the
Metaline Miningl & Leasing Co. and the American Zinc, Lead & Smelting
Co.; however, the Pend Oreile Mines & Metals Co. was the largest producer
in the county. The productive effort of these three zinc and lead producers
was gr ~atly stimulated by defense requirements.
 All tonnage figures are short tons and "dry weight"; that is, they do not
include moisture.
 The value of the metal production herein reported has been calculated at
the following prices. -
