A gold mine above Squaw Creek. A quartz lens containing gold and pyrite occured in the center of a shear zone in a quartz diorite porphyry. An unknown amount of ore was produced.
Structure: The Kobau Formation Was Deposited Along An Active Continental Margin Proximal To An Island Arc.
Deposit: Mining on the grey eagle claim appears to have been carried out on two widley separated veins. One of the veins has also been mined As part of the reco vein in the no. 2 adit of the reco mine. ; info.src : 1 pub lit
Geology: The vein is in siltite and greenstone of the kobau formation; altered granitic rocks occur with the mineralization.
Ore(s): North-Striking, West-Dipping, Quartz And Calcite Veins In Fractures 0.5-6 Inches Wide In Sheared And Brecciated Rock, Visible Gold Is Present In Veins And Stringers. The Adit Is In Hydrothermally Altered Granitic Rocks, Greenstone, And Siltite (Moen, 1980, P. 35).
