Mar 10, 2011 (J Bongfelt) - 'A series of andesitic greenstones and greenstone schists underlie the area of the occurrence and form host rocks for quartz veins which are mineralized with sulphides and gold. The quartz veins intrude the schisted rock and greenstones and are thought to be a late phase of the nearby Nolan Lake granite. The quartz is also accompanied by carbonate alteration. A series of mineralized quartz veins in schist are exposed on a trail which crosses the narrows at t6he base of a peninsula at the east end of Shingwak Lake.'

Mar 10, 2011 (J Bongfelt) - 'At the mouth of the east bay of Shingwak Lake on a trail leading across the base of a peninsula that partly closes the entrance, a number of exposures of quartz are seen in small trenches or pits, and near the east end a wide vein of lenticular form is exposed by stripping for about 250 feet. At its widest part the quartz measures 29 feet, and the average width for the 250 feet was estimated at 8 or 10 feet. This property is known as the Roy Mine.' (ODM - Vol.42, Prt.4, Roy Mine, p.85)

Mar 10, 2011 (J Bongfelt) - 'Grab samples: 0.07 to 0.18 oz./ton Au and 0.23% to 6.2% Cu' '1981: Speculative estimated tonnage & grade in reserves: 18,000/0.12' (OFR 5332, Vol. 2 of 2, p. C-9) * Approx. 450m NE of the occurrence is a showing on the south shore (Roy-east) of Shingwak Lake - best recorded assay result is: 2110 ppb Au (0.061 oz./ton Au) re: 'highly silicified white schistose rock, remnant unaltered green fragments, 2% pyrite cubes, cross cutting 2mm quartz veins.' (Kenora AF 52F/05SE, KKK-3, Bigstone Minerals Ltd., Geo Report, p.27)
Sep 26, 2017 (Therese Pettigrew) - Mineralization consists predominantly of progressively brecciated and carbonated mafic pillowed basalts and equivalent hyaloclastic breccias (AFRI 52F05SE0040). Small pits and trenches were made on a quartz-carbonate vein, the east end of which was stripped for 250 ft, exposing a lenticular-shaped vein, 29 ft at its widest part and averaging 8-10 ft. The vein was reported to be in a chloritic schist in the west and a sheared porphyry in the east. Mineralization was reported to occur in the quartz and brecciated material and consisting mainly of pyrite and chalcopyrite. Grab samples have assays of $1.60-$4.40 gold (1.5 to 4.2 g/t Au) and 0.23-6.2% copper. A channel sample gave a result of only $0.60 gold (0.58 g/t Au) (Burwash, 1934). Sampling conducted in 2005 returned assays of 1.29-2.32 ppm Au (AFRI 20000000900).
