A former Au-Cu-Pb mine located in secs. 23, 24 & 25, T17S, R44E, MDM, 1.9 km (1.2 miles) W of Skidoo, on National Park Service land (Death Valley National Park. Property consisted of 6 claims. MRDS database stated accuracy for this location is 1,000 meters.

The Del Norte Group of mines, just north of the Skidoo Mine operation, had been the site of an important low-grade gold ore discovery in 1936, and a short while later were being actively developed, the ore being trucked to the Keeler Gold Company's mill for treatment.Greene, 1981

Mineralization is a vein deposit hosted in quartzite and quartz monzonite. The ore body strikes N-S and dips 30-70W at a thickness of 0.61 meters. Controls for ore emplacement included fractures. A massive quartzite bed, 25-30 feet thick, strikes E-W and dips 15N, and overlies quartz monzonite. Veins occur along fractures in the quartzite; and a set of parallel veins occur in the monzonite, 1 to 2 feet thick. Local rocks include Cenozoic (Tertiary) granitic rocks? (Skidoo Pluton).

Workings include surface and underground openings comprised of 10 shafts, 10-15 feet deep, and a number of trenches about 100 feet long and 2 feet deep. Two of the shafts are 50 feet deep, about 600 feet apart. A tunnel was driven SW 160 feet into the monzonite to prospect veins in it. The portal was vertically below the E edge of the overlying quartzite bed. In 1939, a shallow incline was sunk on Inyo No. 2 claim and stoped a small tonnage of ore.

Production data are found in: Tucker, W. Burling & Reid J. Sampson (1938).

Several shipments of selected ore reportedly averaged $16 to $25/ton (period values) during earlier production years. The above value from an open cut. No other production records found.

Analytical data results: Samples cut at 5 foot intervals from two 50 foot shafts and 2 trenches assayed $6.00/ton in Au (period values). Ore from the incline sunk in 1939 assayed $35-$50/ton in Au (period values).
