Agency: NF Region District: R1 Ranger District: PHILIPSBURG Forest Service Tract: Watershed Code: 17010202 Forest or Resource Area: DEERLODGE Owner: P Impact: U Report: Basin and Quartz Creek Placers Although this is a placer mine, it was investigated as part of this project because of extensive areas of altered bedrock have been exposed and numerous seeps and springs are scattered throughout the site. Lyden (1946) estimated that 7000 oz of gold has been produced from these drainages since 1904. Near the heads of the gulches a large Tertiary rhyolite porphyry intrusion has been emplaced in sedimentary rocks of the middle Belt carbonate unit. Although the country rock has been contact metamorphosed, the igneous rock appears to be extensively altered and it is now composed mainly of quartz, kaolinite, sericite, and 3% disseminated pyrite. Placer workings extend well upstream of the sedimentary rocks, providing further indications that the source of the placer gold is the intrusion. However, a sample of this ran less than .006 oz/ton Au, .16 oz/ton Ag, .003% Cu, .005% Pb, and .015% Zn. Nonetheless, exploration drilling was proceeding in 1992. The entire site is on private land. An extensive report on the Quartz Gulch closure (1997) is on file in the MBMG mineral property files. |
