Dec 07, 2005 (D McKay) - The Glory Holes occurrence comprises two pits; the G1 pit is located approximately 150 m west of the G2 pit. The G1 occurrence consists of a poorly exposed, bull white quartz vein in a dark, mafic volcanic hornfels. There are pieces of lamprophyre in the dump pile. There is a suggestion that the vein may be relatively flat-lying. Pyrite occurs along chlorite seams in the quartz. The G2 occurrence consists of a flat-lying, bull-white quartz vein in a medium-grained, equigranular granite. The vein has been exposed in a shallow, circular pit approximately 1.5 m deep and 3 m across. Pyrite and rare galena occur in the quartz + feldspar + calcite vein. Pyrite also occurs as smaller, disseminated grains in the granite. Disseminated pyrite in the granite is associated with silicification. The granite may be hematitized, chloritized or biotitized along fracture surfaces or within cavities.

Dec 07, 2005 (D McKay) - Pyrite and rare galena occur in the quartz + feldspar + calcite vein. Pyrite also occurs as smaller, disseminated grains in the granite. Disseminated pyrite in the granite is associated with silicification. Grab samples collected from th G2 vein in 1981 by J. Ferguson are reported to have returned assay values of up to 0.18 opt Au (Schnieders et al. 1996). Grab samples collected from the occurrence in 1988 by OGS Resident Geologist staff returned assay values of <0.01 opt Au and <0.10 opt Ag.
Dec 07, 2005 (D McKay) - Disseminated pyrite in the granite is associated with silicification. The granite may be hematitized, chloritized or biotitized along fracture surfaces or within cavities.
