History
During 1915-1916, the present shaft was sunk to the 100-foot level, and some drifting was done. Further exploration was carried
on in 1921. In 1932, E. Ross Householder leased the mine. Later in the same year, E. F. Niemann and associates, who subsequently
formed the Gold Standard Mines Corporation, obtained control of the property. Up to January, 1934, this company had
done about 1,000 feet of development work on the 100 level and mined ore that, treated in the Gold Standard mill (see page
103), yielded about 890 ounces of gold and 1,734 ounces of silver.
Also called the roadside mine.
