Nov 02, 2010 (J Bongfelt) - The occurrence is underlain by mafic metavolcanic flows of the Eagle Lake Volcanics, east of the contact between the metavolcanics and granitic rocks of the Atikwa Batholith to the west. (OFR 5723, pg.198)
Nov 02, 2010 (J Bongfelt) - A few large trenches and shallow test pits have been sunk on very hard, massive, fine-grained, sulphide-rich mafic metavolcanic flows. The metavolcanics appear to be amphibolitized and contain abundant disseminated pyrrhotite and chalcopyrite. Sulphides are also concentrated in amygdules within the flows. Narrow, discontinuous lenses of interflow metasediments striking 325º/65º NE occur amongst the mafic flows. The metasediments consist dominantly of alternating thin layers of chert, siltstone, and mafic tuff. Narrow and minor glassy gray quartz veins were observed but they contain minor amounts of sulphides. The mafic flows are also intruded by fine-grained felsic dikes. The sulphide-rich flows and metasediments at this occurrence are very similar to the sulphide-rich, gold-bearing mafic flows at the W.W. Smith Prospect, 1.6 km to the northeast, at Hardrock Bay. The flows appear to be situated along the same stratigraphic level. One hole drilled by Frederick [fining Company Limited in 1949 intersected epidotized and carbonatized mafic flows intruded by felsic feldspar and quartz-feldspar porphyry dikes and mafic dikes. The mafic flows were reported to contain up to 3% evenly disseminated chalcopyrite and pyrrhotite. This geology is very similar to the W.W. Smith Prospect at Hardrock Bay. (OFR 5723, pg.198)

Nov 02, 2010 (J Bongfelt) - 'Shear zone occurrence. Best value, 0.04 oz/ton. No other data.' (OFR 5332, Vol.1, p42) '1948: Sampling of shear zones gave 0.04 oz. Au/ton as highest assay.' (Kenora Historical File - OGS 1976, MDC 16) A composite grab sample of sulphide-rich material, taken by the author from a few trenches, assayed 16 ppb gold. (OFR 5723, pg.198-199)
