Access Description: Light aircraft can land on the lake near the occurrence in winter and summer. Boat and snowmobile access to the lake is availible from access points of HWY. 599 between Trappers Point and Horizontal Bay of Sturgeon Lake.
1901-1902: Claim TB 6980 is the location of the Dawson-White mine. A development study was done on the property by the Sturgeon Lake Mining Company. The company sank a -70 shaft to a depth of 70 feet. 50 feet of cross cutting and 30 feet of drifting was done at this horizon. An open cut was excavated to the north of the shaft and a 10-stamp amalgamation mill was installed. 1902-1903: A level was established at 60 ft. and limited cross-cutting completed. 1937: Dawson-White Gold Mines Ltd. took over the property in the spring of 1937. Camps including a bunkhouse, cookery, office and warehouse were built. In the spring. 29 diamond-drill holes were put down, totalling 6 100 feet. On May 23, a two compartment vertical shaft was started about 140 feet north-east of the old (1902) workings. A new headframe, blacksmith shop, cap-house, and powder magazine were erected. Sinking under power was commenced on July 11, 1937 and the shaft was sunk to a depth of 225 feet, with 80 feet of cross-counting, 190 feet of drifting, and 30 feet of raising on the 100-foot level, and 85 feet of drifting on the 200-foot level. It was reported that underground exploration gave encouraging results, but owing to lack of finances, operations were suspended on September 29 and the company was declared bankrupt. 1965: Re-opening and sampling pits on the Dawson location, dewatering and trenching of the old open cuts on location BG 157 and HW 697 and magnetic and electromagnetic surveys over portions of the property (Trowell 1983, p. 96) 1984: Coastoro Resources Ltd. conducted a drilling and geophysical program over the Dawson-White and the La Riviere Zone during the winter of 1983-84. 2110 feet of drilling was done.
Dec 07, 2005 (C Ravnaas) - On location B.G. 157 is what is known as the Dawson Mine, now owned by the English River Gold Mining Company, and formerly controlled by the Sturgeon Lake Mining Company. St. Anthony, it is situated near the contact between the green schists and granite, but instead of lying on the main contact, it lies on the contact between bands of schists and the granite. There are here a number of pegmatite dikes, in some parts composed of about half feldspar and half quartz, and in other parts consisting largely of one or two. The gangue is quartz, and the ore minerals found were galena, sphalerite, pyrite and chalcopyrite. Good specimens of free gold are said to have been found, though we .. any on the dump. The workings include a shaft, open cut and some pits, the former being full of water. The shaft is said to be 64 feet deep, and the open cut is about 70 feet long. 10 feet wide. Much of the country rock is included in this width. The buildings include a mill containing 10 stamps and other equipment, but the ill has been long idle.
