Point Location Description: General
Location Method: Conversion from MDI
Access Description: The occurrence is indicated as a small test pit on J. Satterly's (1943) map of the Dryden-Wabigoon area. (OFR5723, p.224) Deposit Access Description: The Moose Bay Prospect, on former mining locations H.W. 38, H.W. 6, and H.W.63, is situated about 90 m inland along the east shore of Moose Bay on Dinorwic Lake. (Moose Bay is situated along the west shore of Dinorwic Lake, northwest of Stanawan Bay, and is accessible by boat..) (OFR5723, p.248)
Moose Bay Prospect (OFR5723, p.249) 1900-1901: Two shafts were sunk on mining location H.W. 38. One shaft was sunk to 20 ft., while the other was sunk to 40 ft. An open cut was sunk on mining location H.W. 6 as well as a 7 ft. by 18 ft. shaft which was deepened to 102 ft. 1901: The mine was shut down after five months of operation. No production was recorded. 1986: Rediscovered and staked by S. Johnson. 1987: Claims cancelled.
Province: Superior
Geological Age: Precambrian
Mar 08, 2010 (J Bongfelt) - The occurrence is underlain by mafic metavolcanic flows intercalated with intermediate to felsic pyroclastic rocks of the Lower Wabigoon Volcanics. (OFR5723, p.224)
Mar 08, 2010 (J Bongfelt) - Main Shaft and Open Cut: The main shaft and open cut are situated on former mining location H.W. 6. The main shaft is 1.8 m x 2.7 m and is reported to be 102 ft. deep (Carter 1901). The shaft has been sunk on a very wide, intensely sheared (025º/ 60ºE), felsic, feldspar porphyry dike intruding mafic metavolcanic flows. The dike is fine-grained, weakly iron carbonatized, sericitized with some green mica, weathers buff pink, and has a greenish-white fresh surface. The dike contains numerous, tiny [< 1 mm] greenish-white, euhedral, feldspar phenocrysts. Pyrite [ less than or equal to1%-2%] occurs throughout the dike, but is not evenly disseminated. Narrow [< 0.3m], fracture-hosted, white quartz veins occur throughout the dike and contain orange iron carbonate. No pyrite was observed by the author in the quartz veins. In the open cut, which is about 24 m south of the shaft, the majority of quartz veins are tension fracture-hosted, flat-lying, and crosscut shearing. The open cut is about 2.1 m deep, 5.5 m long and about 2 m wide. Shaft No. 2 and No. 3: Shaft No. 2 is situated about 189 m north of the main shaft and 60 m north of a few new, shallow test pits situated about 130 m north of the main shaft, while shaft No.3 is 250 m north of the main shaft and 60 m north of shaft No. 2. Shaft Mo. 3 has been sunk on intensely sheared (020º-030º/65º-70ºW), carbonatized, chloritized, mafic metavolcanic rocks containing 1%-3% finely disseminated pyrite and very narrow [less than or equal to l cm] quartz-carbonate veinlets. The metavolcanics are intruded by a 0.9 m to 3.0 m wide felsic dike, striking about 050º, which is similar to the dikes at the main shaft, open cut, and new test pits. The dike is intensely sheared (025V66 0 W), sericitized, buff pink to green and contains up to 3% finely disseminated pyrite. The dike hosts numerous flat-lying and shallow dipping (20 0 E), tension fracture-hosted, white quartz veins containing orange-brown iron carbonate and minor pyrite. (OFR5723, p.248-249)

Mar 08, 2010 (J Bongfelt) - A grab sample of the pyritic felsic dike containing quartz stringers taken by the author from the No. 3 shaft assayed 645 ppb gold. A grab sample of the sheared and altered mafic metavolcanics taken by the author at the No. 3 shaft assayed 40 ppb gold. Three grab samples of the pyritic felsic dike containing quartz stringers, taken by the author in the vicinity of the No. 2 shaft, assayed 24 ppb, 80 ppb, and 115 ppb gold. Two grab samples of the mafic metavolcanics at the No. 2 shaft assayed 80 ppb and 85 ppb gold. A grab sample of the pyritic felsic dike with quartz stringers, taken by the author from one of the new test pits assayed 1080 ppb gold. No samples were taken from the main shaft area or open cut. (OFR5723, p.249) MNR/OGS Geoscience Laboratories Report, 1987, report the following assay report: - Grab sample from Shaft #1 - Main (shaft edge) = 645 ppb Au - Grab sample from Shaft #1 - Main (shaft edge) = 40 ppb Au - Grab sample from Trench = 1080 ppb Au (Kenora Property Visit File 52F/10SE00013, Moose Lake Mine)
