Dec 07, 2005 (D McKay) - Schnieders et al. (1996) state: The area was mapped by Walker (1967) as granite gneiss and hybrid rocks. However, in the vicinity of the vein the rocks to the north appear to be granite (footwall) whereas in the hanging wall rocks appear to be mafic volcanic rocks. The showing consists of a white quartz vein exposed in the bottom and side of a small creek bed. The strike of the vein is approximately 300 degrees azimuth and dips at about 45-50 degrees to the west-south west. Where exposed the vein is only 9-12 cm wide and the strike length of the exposure is 3-5 m. The quartz vein exhibits some hematite coating along fracture cleavages. Boudinaged, narrow quartz veins are roughly foliation-parallel at 115/80 to 115/60. Foliation wraps around curviplanar contacts with the granitic rocks. Quartz pods or boudins may become detached. Crude crack-seal chloritic slips are developed in the vein. Small crenulations occur in the host chlorite schist.

Dec 07, 2005 (D McKay) - The quartz is mainly white bull quartz with rare pyrite, calcite, epidote and hematite. However in the creek bed itself the vein is mineralized with pyrite and possibly pyrrhotite and a silver metallic mineral which has been tentatively identified by Ontario Geological Laboratory, Toronto by x-ray diffraction as nuffieldite and by Lakehead University also as nuffieldite (Pb 10, Bi 10, Cu4, S27) or possibly joseite. Other elements in the sample were identified by Lakehead University to contain Ag, Te, Cu, Bi, Pb, Si and S (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay). Kissin and McQuaig (1988) noted the occurrence of an unidentified Cu-Bi-Pb-sulphide, as well as hessite (Ag2Te), argentite and native bismuth. Patterson et al. (1987) report a selected grab sample (86-BJF-05) indicated values of 0.38 ounce per ton Au and 118.88 ounces per ton Ag. In addition another grab sample (86-BJF-01) assayed 0.20 ounce per ton Au and 47.36 ounces per ton Ag. Grab samples collected from the occurrence in 1986 by OGS Resident Geologist staff returned assay values which varied from 1480 ppb to 0.4 opt Au, 6.22 to 98.96 opt Ag, 2.0 to 5.5 ppm As and 3600 ppm to 5.5% Bi. Ten samples (87-BJF-18 to -27) submitted by J. Ferguson in 1987 to the OGS for analysis assayed as high as 0.16 ounce per ton Au and 31.34 ounces per ton Ag. Four grab and chip samples collected in 1988 (88 BJF -10 to -13) by OGS Resident Geologist staff returned no gold nor silver.
