Geologic setting

Geologic description

At the Oscar West prospect, local gossan-bearing rubble and boulders occur in Paleozoic biotite schist with marble interbeds as much as 150 feet thick (Dashevsky and others, 1986). Two hundred feet west and 200 to 300 feet east of the gossan occurrence, a 50- by 80-foot soil anomaly contains as much as 9,000 ppm lead, 1,800 ppm zinc, and 43 ppm silver. A grab sample of the gossan contains 0.02 percent copper, 0.87 percent lead, 1.02 percent zinc, and 1.25 ounces silver per ton. Several other prospects are associated with the Mount Veta intrusive complex, including Little Enchilada (EA103), East Eva (EA098), Eva Creek (EA099), Little Whiteman Creek (EA060), Oscar (EA096), unnamed (north of Fish Creek) (EA062), Molly Creek (EA100), and Mitchell (EA101).
WGM Inc. conducted reconnaisance mapping and prospecting in the Oscar West prospect area in 1976 and sampled the soil on a small grid in 1977 (Dashevsky and others, 1986). A trench dug in 1977 did not reach bedrock.

Mineral deposit model Cu skarn or Zn-Pb skarn (Cox and Singer, 1986; models 18b or 18c).
Mineral deposit model number 18b or 18c
Age of mineralization Skarn mineralization in the Oscar prospect area appears to be at the contact of the Mount Veta syenite of Jurassic age and Paleozoic marble, calc-schist, and quartzite.
