Alteration: Strong gossan-like oxidation

Commodity: Ore materials: gold, cerargyrite, argentite gangue materials: quartz, sericite, pyrite, calcite, iron oxides

Deposit: The mine area consists of a system of E-W veins in a shear zone that crosses the range. Veins cut Mesozoc and Tertiary metamorphic and volcanic rocks and andesite and rhyolite dikes that occupy many of the fault strands. Near the surface, the veins have a braided pattern and range in thickness from 2 to 10 ft. Veins consist of vuggy, fine-grained quartz, angular fault breccia, and locally abundant pyrite and calcite. Ore is mainly free-gold, cerargyrite, and argentite. Silver values reportedly increase with depth. Sample 3953 was collected from a shaft at the east end of the vein system, and consists of vuggy, iron-stained quartz and sericite without visible mineralization.

Deposit type: Epithermal vein, Comstock

Development: The property was developed from 1912 to present with sporadic production. The property lay idle after discovery in 1905 until 1912 when Leslie L. Leonard prospected it with good results, after which he and C.W. Kinney jointly sunk a 130-ft shaft and found the 8-ft vein carrying mill-grade ore all the way down with a payshoot dipping westerly. In 1919 the Martin brothers took a lease and bond on the property, sunk several more shafts and shipped 150 tons of $125-$300/t ore. They also opened several parallel veins containing rich pockets of cerargyrite ore. In 1923, channel samples over 3000 ft along the deposit by a N.Y. firm, averaged $15.80/ton in gold. In 1924 the mine was purchased by Senator N.H. Getchell who incorporated the property as the Dan Tucker Mining Co., who worked it and found 4 new 3-ft ore shoot. In 1927, the mine was said to be worked by lessees. In 1934, after several years idle the mine, under lease to Rosetta Mines Co. became active again. Some production was reported from the district in 1938 and 1940. The mine was owned and operated by Summit King mines, Ltd.in 1951. In 1985, Capri Resources Ltd. reported commencement of a major bulk sampling and 7-hole diamond drilling program on the Summit King property, fully funded by Tri-Basin Resources Ltd, who may earn up to a 50% interest in the property.

Ores(s): Large e- W shear zone dipping steeply south
