Dec 07, 2005 (P Hinz) - The area is underlain by the High Lake porphyritic granodiorite stock, which intrudes Archean mafic metavolcanic rocks. The stock has been interpreted to be two intrusivde phases (Davies 1965, Colvine 1979).

Dec 07, 2005 (P Hinz) - In the vicinity of the pits, the basalt-porphyry distribution is complex. On the basis of surface exposures it appears that there area several quartz porphyry dikes or lenses separated by basalt, but drilling has indicated that the geology is equally complex in the third dimension. The trends of some shearing and of a narrow porphyry dike suggests that a south-southeast striking cross fault may occur near the pits.

Jul 15, 2020 (P Hinz) - Pits or trenches were sunk in basalt cut by quartz porphyry and felsite. Mineralization is reported to be associated with thin quartz veins in felsite and altered quartz porphyry; to consist of electrum arsenopyrite, pyrite, pyrrhotite, chalcopyrite, tourmaline and traces of galena and sphalerite; and to extend slightly into the enclosing basalts (Davies 1965, p.33). Best intersection from 1958 drilling assayed 1.56 opt Au and 1.2 opt Ag over 2.1 ft., 0.74% Cu over 1.5m was also encountered.
