The Amador Queen No. 2. Location: sec. 34, 35, T. 6. N., R. 11 E., M.D.M, 2 miles south of Jackson. Ownership: Judge Ralph McGee, Sutter Creek, California.
The chief production of gold from this mine was prior to 1900. By that date the greater part of the underground workings had been developed (Logan, 1934, p.108). From 1918 (Logan 1934, p.60) to 1941 the mine was operated intermittently, with a production of a few thousand dollars nearly every year. The mine was worked intermittently by the Garibaldi Brothers from 1930 to 1941, according to Mr. Frank Garibaldi. In 1948 an unsuccessful attempt was made to treat the tailings.
The Amador Queen No. 2 was worked through a 1200-foot west-driven adit. Drifts were run 1000 feet south and 460 feet north from the end of the adit. Also a winze 900 feet deep was sunk along the dip of the slate with levels at 500 and 700 feet (Logan, 1934, P. 60). In the 1930’s a 230-foot winze was sunk about 100 feet from the end of the adit.
Gold occurs with arsenopyrite in quartz stringers in east-dipping Mariposa slate (Logan, 1934, pp. 60-61). The slate is interlayered with schist, some of it being hard and siliceous. In the last ten years of operations, production was chiefly specimen ore.

Mineralization is a quartz vein deposit hosted in slate and greenstone. The ore body strikes N and dips E. The quartz vein material was mixed with soft slate. Gold occurs with arsenopyrite in quartz stringers. Local rocks include Jurassic marine rocks, unit 1 (Western Sierra Nevada and Western Klamath Mountains).
Workings include underground openings with an overall depth of 129.54 meters, and comprised of a 1,300 foot crosscut adit, a 170 foot vertical shaft, a 490 foot 62 degree inclined shaft on the footwall with a short crosscut to the hanging wall. 1,200 feet of drifts on the adit level plus a raise from the adit to surface at the slate-greenstone contact. The ore shoot is 1,200 feet (long ?).
Analytical data results: Sulfides constitute 3% of the ore. Au associated with sulfides assayed at $90 to $110 (period values) per ton.
