Geologic setting

Geologic description

This occurrence is a zone of quartz veining at the contact between granite porphyry and diorite (Bundtzen and others, 1998). The details of the intrusive contact is unclear and the mineralization is poorly understood. One grab sample of the quartz vein contained 9 parts per billion (ppb) gold, 72 parts per million (ppm) copper, 94 ppm lead, 86 ppm tungsten, 167 ppm lanthanum, 28.3 ppm samarium, 800 ppm cerium, 2,200 ppm zirconium, 8.5 ppm uranium, 51.0 ppm thorium, and 8.4 ppm mercury (Bundtzen and others, 1998).
