Dec 07, 2005 (C Ravnaas) - The area is underlain by the High Lake porphyritic granodioritie stock, which intrudes Archean mafic metavolcanic rocks. The stock has been interpreted to be two intrusions (1965, Colvine 1979). The P zone is close to a prominent linear feature, which trends about 065. (Davies and Smith 1988) Davies (1965, p32) states, Visible gold shears along the north side of this lineation suggested that the linear feature may be a fault zone, which acted as a favourable structure for mineralizing solutions.

Dec 07, 2005 (C Ravnaas) - Visible gold is associated with sheared quartz-feldspar porphyry. There are no strong shears, but more fractures. Thin quartz veins, in places containing tourmalinem, are also more abundant in the highly altered rock (Davies 1965).
Mar 10, 2015 (Therese Pettigrew) - The High Lake stock is generally referred to as a porphyritic granodiorite. Typically this rock is grey weathering and massive, containing about 60% plagioclase, 30% quartz and up to 10% biotite. Greyish quartz-eyes and coarse, euhedral microcline crystals (up to 4 cm long) are frequently present (AFRI 52E11NE9222).

Mar 10, 2015 (Therese Pettigrew) - Gold is found in zones of shearing within clean, uncontaminated High Lake granodiorite. It is associated with pyrite-filled fractures and with pyrite-bearing quartz tourmaline veins (AFRI 52E11NE9222). A total of 1,924 feet was drilled by Electrum Lake Gold Mines in 14 holes, but only three holes have good mineralized intersections: E-34: 0.21 opt Au from 36.0-56.5 m; E-60: 0.117 opt Au from 131.0-146.0 m; E-63: 0.674 opt Au from 134-146.5 m. These three intersections are on three adjacent sections and do not line up, likely indicating en echelon zones. Assuming that the mineralization extends for 60 feet along dip and halfway to adjacent sections there are 10,000 tons at 0.29 opt Au with an average width of 12.96 feet using a tonnage factor of 11.50 cubic feet per ton (AFRI 52E11NE9032).
Dec 07, 2005 (C Ravnaas) - Iron oxide stains is present throughout most of the rocks, giving it a red to reddish-brown colour. Sulphides (pyrite and some chalcopyrite) are present on fractures surfaces, but in more strongly hematized portions sulphides are disseminated. Where the porphyry is stained, pyrite is less abundant, and large feldspar phenocrysts are typically white or partially pink. Gold is clearly associated with the more highly altered porphyry.
