|Location and accuracy||The Cache Creek North occurrence is a soil-rubble anomaly located at an elevation of 1,500 feet (457 m) in a stream basin of the South Fork of White Mountain Creek in Section 20, T. 22 S., R. 25 E., of the Kateel River Meridian. Location is known to within 250 feet (76 m).|
Geologic descriptionMineralization only occurs as rubble-crop of the Silurian Paradise Fork Formation of Dutro and Patton (1982), which is also unit 'Sic' of Andrews and Rishel (1982). Cache Creek North is northern end of N 55 E striking unit of micritic limestone and white dolomite. The host rock is inferred to be Silurian based on fossil control (Dutro and Patton, 1982). A 3,000 foot-long (915 meter) soil anomaly contains up to 1.05 percent zinc and 450 ppm lead (Andrews and Rishel, 1982).
