Comments on the geologic information

  • Geologic Description = The Louise prospect is about 1,500 feet northwest of the Owhat prospect (RM016). According to Bundtzen and Laird (1991), it was first reported by Holzheimer (1926) as a 1,000-foot-long gold-arsenic deposit. Bundtzen and Laird (1991) described the deposit as an arsenopyrite, chalcopyrite, quartz, and black tourmaline vein that trends northwest for at least 245 feet along the contact between syenite and an altered andesite porphyry dike. The width of this poorly exposed vein could not be determined. A sample of the vein contained 4.1 ppm gold, 10 percent arsenic, 0.99 percent antimony, and 0.12 percent tin (Bundtzen and Laird, 1991). The host rocks are part of the Upper Cretaceous intrusive complex of the Russian Mountains.
  • Age = Late Cretaceous or Tertiary. Veins crosscut part of the intrusive complex of the Russian Mountains. Quartz monzonite from this complex has yielded a K/Ar age of 70.3 +/- 2.1 Ma (Bundtzen and Laird, 1991).
