Access Description: Light aircraft can land with light loads on McEdwards Lake in summer and winter under most conditions. In summer boats can be launched from access points to Sturgeon Lake on Hwy. 599. From the southern portion of Belmore Bay a light boat can be carried or dragged over a short portage to McEdwards Lake. Areas of heavy blow-down hinder access to large areas on the east side of McEdwards Lake and access from the lake is advised in summer and winter.

Exploration and Mining History

1912-1937: Very little is known about the early exploration history of this property. The earliest record of exploration on the property in the files is a news item from the News Chronicle (Thunder Bay) dated Feb. 8, 1937. Mr J.C. Beidelman stated that he was incorporating a company to work the McEdwards claim group which he had staked 25 years previously, (i.e around 1912). 1981: Moran Resources Corporation conducted aerial geophysical surveys, rock and soil geochemical sampling and trenching over the McEdwards Lake property. 1983: Moran Resources Corporation reported geological surveying, trenching and assaying on the McEdwards property. 1984: Moran Resources Corporation drilled a 335 foot hole on the property. 1985: Moran Resources Corporation was renamed Stornaway Resources Corp. The new company drilled 3 holes totalling 817 feet on the McEdwards property. 1988: Krigold Resources Ltd. acquired a claim block covering the McEdwards Lake property and additional claims on the east shore of lower Belmore Bay. The company examined the property, carried out a geochemical sampling program for gold, and drilled 4 DDH totalling 351.4 m. 2011: Paragon Minerals Corp. staked the property and carried out prospecting and sampling.

Geology Comments

01/28/2000 (R Tuomi) - Detailed studies of geology, geochemistry and geophysics outlined a 184 m long zone on the McEdwards Lake property. The zone, which trends approximately east-west, is located in a series of mafic to felsic metavolcanic rocks in contact with a quartz porphyry stock. The zone is characterized by quartz veining and pyrite mineralizationfrom 5% to 20% in the host rock. Gold values range from trace to 0.74 ounce gold per ton and occur both in the quartz veins and in the sulphide host rock which is silicified and carbonatized in part. Geophysical indications suggest that the zone may extend for 100 to 150 m under McEdwards Lake.

Mineralization Comments

02/10/2000 (R Tuomi) - 1937: The 14 claim group was stated to have surface showings of gold in quartz associate with porphyry dikes. The showings had a length of 200 feet and assays of up to 15 ounces gold per ton over a width of 3 feet. The veins were located in a zone up to 24 feet wide. 1983: Surface samples returned up to 0.74 ounce gold per ton and zone length was extended to 600 feet. 1985: Drill hole ME-3 samples gave from trace to 0.42 ounce gold per ton with a 1.2 m section of core assayed at 0.25 ounce gold per ton. Most of the drill and surface workings are located in blow-down timber which is very difficult to cross or clear out.

04/15/2020 (T Pettigrew) - The McEdwards prospect consists of a gold-bearing, quartz vein zone associated with moderate to strongly, carbonate altered, pyritic-felsic rocks and lesser mafic rocks. The quartz-carbonate veins typically contain pyrite-chalcopyrite-arsenopyrite mineralization with local malachite staining and visible gold. The gold mineralization has been traced over a length of 180 metres and widths up to 7 metres by previous workers and remains open along strike. In 2011, a total of 48 grab samples were collected with assays ranging from trace to 30.8 g/t Au. Nineteen samples assayed greater than 0.5 g/t Au, including 11 samples with assays greater than 5.0 g/t Au (Assessment report 20000006555). Krigold’s DDH 2 returned 0.05 oz/t Au over 6 feet (1.71 g/t Au over 1.8 m) from a metabasite shear. DDH 3 returned 0.25 oz/t Au over 4 feet (8.57 g/t Au over 1.2 m) from veins with pervasive silicification and sulphide mineralization. Metabasite with some calcite and quartz veinlets and 5% sulphides returned up to 0.18 oz/t Au over 2 feet (6.17 g/t Au over 0.6 m). DDH 4 returned up to 0.06 oz/t Au over 1’7” (2 g/t Au over 0.48 m) from a shear zone in metabasite with calcite and siderite veins (Assessment report 52J02SE8658).
