Point Location Description: Approximate
Location Method: Based on Assessment
Access Description: Whitewater Lake is immediately east of Kaminnassin Bay of Dinorwic Lake and north of Minnehaha Lake. The majority of occurrences are accessible by boat. (OFR5723, p.221)
1986-1987: Staked by S. Johnson. Stan and Sherridon Johnson also made new gold discoveries on the east shore of Whitewater Lake and northwest of the lake. All previous work and staking had been centered on the original discovery by Carl Mosher. Comaplex Resources optioned the property and conducted reconnaissance mapping, sampling and prospecting. Comaplex subsequently dropped the option which was picked up by St. Joe Canada Inc. (OFR5723, p.223)
Province: Superior
Geological Age: Precambrian
Mar 08, 2010 (J Bongfelt) - The occurrences are situated within mafic to felsic metavolcanic flows and pyroclastics of the tholeiitic to calc-alkaline Lower Wabigoon Volcanics. The gold occurrences are 2.4 km west of the northeast-trending Manitou Straits Fault and occur within numerous north-northeast-trending shear zones parallel to the fault. (OFR5723, p.221)
Mar 08, 2010 (J Bongfelt) - The new test pit on the east shore of the lake has been sunk on quartz veins hosted by pale gray, pillowed, mafic, metavolcanic flows with abundant amygdules and feldspar phenocrysts. The rocks are carbonatized (calcium carbonate), sericitized, and contain up to 15% fine-grained, disseminated pyrite and are sheared at 015? to 020º, dipping vertically or steeply west. Quartz veins are controlled by shearing, and by northwest- or west-trending tension fractures which crosscut shearing. Veins are generally 5 cm to 10 cm wide with numerous blue-gray quartz stringers occurring throughout. Veins contain angular fragments and "stringers" of very pyritic wall rock and chlorite but pyrite doesn't commonly occur within the quartz. (OFR5723, p.221) Another eastern gold showing is located at an old open cut situated between Whitewater Lake and Kaminnassin Lake. The open cut has been driven on a 0.6 m wide quartz vein and numerous narrow quartz veinlets hosted by intensely sheared mafic metavolcanics. The shear zone strikes 020? and dips steeply west. The host rocks are fissile, carbonatized, sericitized, and pale green-yellow with a "waxy" appearance. The rocks contain abundant fine-grained, finely disseminated pyrite. The quartz veins consist of white quartz, iron carbonate, and contain variable amounts of pyrite, chalcopyrite, galena, and some malachite. (OFR5723, p.222)
Mar 08, 2010 (J Bongfelt) - * Test Pit: visible gold was observed in the quartz veins by the author. Three random grab samples of the wall rocks, taken by the author, assayed 345 ppb gold, 2070 ppb gold, and 3610 ppb gold, while two samples of the quartz vein material assayed 200 ppb gold and 1480 ppb gold. (OFR5723, p.221) * Old Open Cut: two grab samples from the quartz vein, taken by the author, and containing <1% sulphides, assayed 0.76 ounce gold per ton and 1.62 ounces gold per ton, while a sample of the wall rock assayed 8100 ppb gold.
