This collection contains correspondence, business papers, ledger books, maps and reports
of the Consolidated Virginia Mining Company of Virginia City, Nevada, dating from 1876-1955. The materials document mines
and mineral resources in Nevada;
the Comstock Lode and other mines, and the mining industry and finance.
The Consolidated Virginia Mining Company on the Comstock Lode at Virginia City, Nevada, was
organized in 1867, but the sinking of a shaft was delayed for two years. The lode was
difficult to find, work stopped, and the stock fell considerably in 1870. In 1871, James
Flood began to buy stock in Consolidated Virginia and, joined by John Mackay, James Fair,
and William O'Brien, formed the Bonanza Firm. They bought the land owned by the Consolidated
Virginia Mining Co. and hoped to find rich ore in that section between the Gould & Curry
and the Ophir mines. In 1873, they struck the Big Bonanza, which produced over $100 million
of ore from 1873-1882. The firm bought control of the adjoining Ophir and Mexican mines in
1877. Although the firm dominated the Comstock from 1876-95, when Mackay sold the interests
to San Francisco stockbrokers, the last dividend was paid in 1880. The Con-Virginia was the
most successful mine on the Comstock and one of the few to pay more in dividends than it
levied in assessments. In the 1930s, the company was reactivated to mine and mill the lower
grade ore still remaining. The reactivated firm in 1933 collected old maps and also made
detailed new maps of the older workings, level by level.
