1902: N. Higbee and associates discovered the occurrence. They drove an adit for 50 feet (Carter 1904) 1988-1989: B. Barton relocated the old adit. He stripped and sampled the occurrence. (OFR 5731, p.120)

Feb 14, 2011 (J Bongfelt) - 'Geology and Alteration: The occurrence lies within a large intermediate to felsic intrusion, immediately north of the Mulcahy Lake Intrusion (Sutcliffe and Smith 1985). The gold-bearing veins are hosted by carbonatized quartzdiorite which contains blue quartz eyes. The primary texture of the quartzdiorite is strongly masked and overprinted by the pervasive ankerite alteration. The area is characterized by many anastomosing conjugate shear zones.' (OFR 5731, p.118)
Feb 14, 2011 (J Bongfelt) - 'An old adit is located 13 m southeast of the lake shoreline. The stripped area above the adit exposes three narrow quartz veins: two parallel veins striking north northeast, and a third cutting them at a high angle.' 'The quartz veins are medium grey, locally a smokey grey. The quartz is massive and opaque, rarely vuggy. Mineralization consists of up to 1-2% medium to coarse grained pyrite, up to 1% medium grained chalcopyrite, and malachite staining. The veins vary from 10 to 16 cm in width.' (OFR 5731, p.118 & 119)

Feb 14, 2011 (J Bongfelt) - Twenty grab or chip samples were taken by the author, P.C. Delisle. The best assays of chip samples in each of the three veins were: Vein #1: 1.76 g/T/12cm; Vein #2: 8.13 g/T/l9cm; Vein #3: 1.88 ounce gold per ton over 16 cm (OFR 5731, p.118 & 119)
