Comments on the geologic information

  • Geologic Description = Irregular masses and disseminated grains of galena, sphalerite, pyrite, and chalcopyrite occur in dolomitic limestone. In the best exposures along Taylor Creek, pervasively disseminated pyrite, galena, and sphalerite occur over an area about 3 m wide by 7 m long in a brecciated zone. This zone occurs in a thinly laminated to phyllitic, light-gray and white, fine-grained dolomitic marble which overlies green crenulated muscovite-chlorite-calcite schist. The mineralization persists for approximately 100 m along the southwest bank of Taylor Creek. Maximum assay values in drill cores and outcrop samples collected by Kerns (1950) were 4.3% Zn, 0.95% Pb, and 1.2 ounces silver per ton. Several origins for the deposit has been suggested, none very convincingly. Spatially and possibly genetically associated with the Duncan Canal-Zarembo belt of massive sulfide mineralization defined by Berg and Grybeck (1980), and Berg (1981). ? Brew, Ovenshine, Karl, and Hunt (1984) show that the host rocks are a small sliver of Upper Triassic Hyd Group that consists of felsic and intermediate volcanics, limestone, and argillite. Recent geologic mapping (Sue Karl, oral communication, 1998) indicate that Hyd Group rocks are much more extensive in the area.
  • Age = Unclear; possibly Triassic based on analogy with other massive sulfide deposits in the Duncan-Zarembo belt defined by Berg and Grybeck, 1980.

Comments on the workings information

  • Workings / Exploration = Prospect known since at least 1904. Considerable activity during the 1940's, mainly restricted to surface sampling and some trenching and pitting (Fowler, 1948 [DGGS IR 195-2]; Fowler, 1948 [DGGS IR 117-5]; Roehm, 1946 [DGGS IR 195-41]; and Roehm,1946 [DGGS IR 117-4]). The property has been been intermittently active since. Kerns (1950) reported on extensive diamond drilling carried out by the U. S. Bureau of Mines in 1948 and the 14 trenches they dug on several areas of mineralization. At least one company active on the property in 1998.
