Geologic descriptionThis deposit consists of sulfide- and scheelite-bearing quartz veins, layers, and lenses as much as 6 inches thick separated by sulfide-bearing schist. The quartz bodies are parallel to the foliation in the schist. The deposit was first reported by Collier and others (1908, p. 193) as a gold prospect. Selected samples contained as much as 0.5 ounce of gold per ton. The same locality was probably reported as the Lynx claim by Mertie (1918 [B 662-I, p. 457]). The deposit was developed by a 60-foot shaft. Scheelite, quartz, and sulfidized schist were run through a sluice box, and about 600 pounds of scheelite were recovered. A dredge working below the deposit recovered scheelite in placer gold concentrates. Cathcart (1922, p. 241) reported a 20-foot-long adit at about the same location. The adit exposed a 1-foot quartz-feldspar vein within highly sulfidized schist walls. Cathcart (1922, p. 234, 241-242) described other nearby deposits, including mineralized schist similar to Sophie Gulch (NM208), in a gully south of Glacier Creek immediately above Snow Gulch. At that location, a quartz-feldspar vein cuts contorted sulfidized schist. Anderson (1947) reported scheelite and stibnite in prospects in the Glacier Creek - Snow Gulch area. |
