Geological Age: Precambrian
Nov 02, 2010 (J Bongfelt) - The occurrence is situated at the north end of a subvolcanic gabbro stock intruding brecciated mafic and felsic metavolcanic flows and mafic to intermediate heterolithic pyroclastic debris flows. The gabbro is intruded by felsic and mafic dikes. The occurrence is situated within the mixed, tholeiitic to calc-alkaline Lower Wabigoon Volcanics. (OFR5723, p.164)
Nov 02, 2010 (J Bongfelt) - The A.L. 88 Occurrence consists of four deep test pits sunk within altered gabbro hosting a stockwork of abundant, narrow, parallel and subparallel quartz veins and stringers located in tension fractures striking 135º-140º. The quartz veins contain tourmaline, carbonate, and disseminated pyrite (1-2%). The gabbro is massive, gray-green, medium-grained, and variably altered, with weak to intense carbonate alteration (calcium carbonate with some iron carbonate), sericitization, and pyritization. The gabbro contains finely disseminated magnetite and 1-2% disseminated pyrite. An outcrop of massive, intermediate metavolcanic flows is located immediately east of the A.L. 88 Occurrence, along the north edge of a small swampy area surrounding a small creek. The outcrop is on the east side of the creek and consists of aphanitic, gray-green, strongly magnetic, pyritic (H), and weakly to moderately carbonatized, massive, intermediate flows. A grab sample taken from the outcrop by J.R. Parker assayed 550 ppb gold. A 1.8 m x 1.8 m x 3 m deep test pit is located at the northeast corner of mining location A.L. 88. It is situated on the south side of a small outcrop, at the edge of a small swampy area about 240 m north of Flambeau Lake. A wide shear zone striking 085º hosts a 0.3 m to 0.6 m wide, white to pinkish-red, quartz vein containing tourmaline and <1% pyrite. The host rocks are pyritic, intermediate to felsic, autoclastic flows with red-brown gossan occurring over much of the outcrop surface. The wall rocks in the shear zone are pyritic, sericitized and intensely carbonatized. (OFR5723, p.164)

Nov 02, 2010 (J Bongfelt) - Re: Occurrence results: A grab sample, taken by J.R. Parker, from quartz vein material in the most easterly trench at the lake shore assayed 0.55 ounce gold per ton, while a grab sample of the altered, pyritic, gabbro assayed 40 ppb gold. Grab samples, taken by Voyager Explorations Limited, from the dump at the most easterly test pit at the lake shore assayed between 3267 ppb gold and 22,500 ppb gold, while grab samples from the dump at the most westerly test pit assayed between 2368 ppb gold and 13,800 ppb gold. (Assessment Files, Resident Geologist's Office, Kenora). A grab sample taken by J.R. Parker from the quartz vein in the test pit at the northeast corner of A.L. 88 assayed 250 ppb gold, while a sample of the altered, pyritic, wall rock assayed 75 ppb gold. (OFR5723, p.164 and Kenora Property Visit File 52F/10NW00030, A.L.88) Re: Prospect results: Extensive diamond drilling was done in 1988-89 by International Platinum Corp. by the easterly lake shore area which intersects with grade surface sampling. Best assay results Au oz/ton: 4.58, 3.59, 3.49, 1.57, 1.48, 1.17, 1.04.
