MINING METHODS AND COSTS, LINCOLN TUNGSTEN MINE,
WAH CHANG MINING CORP., LINCOLN COUNTY, NEV.-/
by
A. C. Johnson2 and Ross M. McDonald-
SUMMARY
This paper is one of a series being prepared by the Bureau of Mines on
exploration, development, mining methods and costs at various mines in the
United States. It describes such methods at the Lincoln tungsten mine of the
Wah Chang Mining Corp., Lincoln County, Nev. The purpose of these reports
is to promote development and conservation of our mineral resources by dis-
seminating technologic information on mining methods, practices and costs.
The Lincoln mine in Lincoln County, Nev., in the southeastern part of the
State, was acquired by the Wah Chang Mining Corp., in April 1951. Mining
methods and costs are of special interest at this property because of the low
costs and good production record achieved through a well planned program of
exploration, development, and exploitation. Operations were discontinued in
July 1957 after the Federal Government suspended the tungsten purchase program.
The mine was developed by the Callahan-Carlisle, 100-, 200-, 300-, 500-,
600-, 750-, and 900-foot levels.
Shrinkage stoping with drawpoint loading was the principal mining method.
An incentive pay system, good planning, and mechanization were the important
factors in maintaining a high production with low costs.
INTRODUCTION
