Abstract

The Calico silver district as a whole is claimed to have produced 13-20 million ounces of silver. The district contains the Silver King, Oriental, Burning Moscow, and Red Cloud mines. The purpose of this study was to estimate the total silver production from the Silver King mine, using ore pillar grades and stope volumes estimated by field work. An estimated 20-24 million ounces of silver were produced from the main Silver King vein and black oxide pockets in the mine, based upon this field work. The discrepancy between the lower historical estimate and the geological estimate in this study is attributed primarily to poor historical records and corporate fraud.
