Geology Comments

Apr 15, 2010 (J Bongfelt) - The occurrence is situated within dioritic rocks of the Atikwa Batholith approximately 600 m south of its contact with mafic metavolcanics of the Eagle Lake Volcanics. The batholith is intruded by a wide west-northwest-trending diabase dike immediately north of the occurrence. (OFR 5723, Pidgeon-Trap Lake Occurrence, pg. 274)

Lithology

Lithology Comments

Apr 15, 2010 (J Bongfelt) - A deep test pit has been sunk on a 1.5 m to 1.8 m wide quartz vein striking 142º/ 82º SW within fine-grained, massive, gray, quartz-hornblende diorite. The diorite is relatively unaltered with very weak carbonatization and sericitization, and strong chloritization, in proximity to the quartz vein, with epidote along hairline fractures. The wall rocks next to the vein contain ? 1% disseminated pyrite and chalcopyrite. The diorite contains abundant small [<1 mm] elliptical, blue quartz "eyes" which may be a cataclastic texture. The quartz vein consists of white and gray quartz containing xenoliths of dark green chlorite and large, abundant, massive, "blobs" of pyrite and chalcopyrite with malachite and azurite. Narrow quartz veins occur sub-parallel to the main vein. The diorite is not pervasively sheared but hosts sub-parallel, narrow, shears generally striking 120º-140º and dipping steeply southwest. Quartz veins are controlled by tension fractures. Some veins appear to have shallow dips and variable strikes but exposure was too poor to determine their orientations. (OFR 5723, Pidgeon-Trap Lake Occurrence, pg. 274)

Mineralization

Mineralization Comments

Apr 15, 2010 (J Bongfelt) - An average of three channel samples, taken by G. L. Pidgeon and A. Lantz, assayed 0.11 ounce gold per ton, 1.02 ounces silver per ton, and 2.31% copper across an average width of 4 ft. Assays up to 0.08% nickel and 0.05% cobalt were also obtained. Another chip sample assayed 0.03 ounce gold per ton, 0.57 ounce silver per ton, and 3.03% copper (Thomson 1954, 1957; Shklanka 1969). Three grab samples of the sulphide-rich quartz vein, taken by the author (J.R. Parker), assayed 1355 ppb gold, 55 ppm silver, 6.9% copper, 490 ppm nickel and 92 ppm cobalt; 530 ppb gold, 30 ppm silver, 4.05% copper, 170 ppm nickel and 180 ppm cobalt; and 0.27 ounce gold per ton, 26 ppm silver, 1.78% copper, 100 ppm nickel and 234 ppm cobalt. A grab sample of the wall rock assayed 27 ppb gold and 130 ppm copper. (OFR 5723, Pidgeon-Trap Lake Occurrence, pg. 274)

Nov 23, 2017 (Therese Pettigrew) - The vein is 9 feet wide and exposed for a length of 170 feet (Shklanka, 1969). Samples from the 1992 prospecting program returned assays of 0.559-2.024 ppm Au and 25,420-42,190 ppm Cu (2.54-4.22% Cu) (AFRI 52F16SE0014).
