Location: Sainsbury (1961) reported a mineral occurrence near a logging road on the west side of Kina Cove. Hedderly-Smith (1999 [Inventory]) locates this or another nearby occurrence west of the head of Kina Cove, in the SW1/4 section 32, T. 73 S., R. 85 E. The Hedderly-Smith location is used for this record.
Geology: Sainsbury (1961) reported about 2 percent chalcopyrite in recrystallized limestone in a stream bed on the west side of Kina Cove, and as much as 5 percent chalcopyrite in a knob of recrystallized limestone on the shoreline of the cove. The limestone is probably part of the Descon Formation of Silurian and Ordovician age. At or near this location, Hedderly-Smith (1999 [Inventory]) found a 12-inch-thick quartz-pyrite vein in an altered zone in greenstone. A sample contained 904 parts per million (ppm) copper, 2.14 percent zinc, 3.7 ppm silver, and 910 parts per billion gold.
Workings: Only surface sampling by government and industry geologists.
Age: Unknown, other than that the occurrences are in Silurian or Ordovician rocks.
Alteration: Greenstone near a quartz vein is altered.
Commodities (Major) - Au, Cu, Zn
Development Status: None
Deposit Model: Chalcopyrite in marble and quartz vein in greenstone.
