Great Bear will continue to focus on its Red Lake, Ontario gold projects, Dixie Lake and West Madsen. The Dixie Lake property overlies a structurally-controlled from-surface gold-mineralized zone with over 1.7 kilometres of strike length and several satellite zones. The project is located 20 kilometres south of Red Lake and is accessible by road year-round. Over 160 drill holes were completed between the late 1980's and 2012 at the Dixie Lake project, with an additional 8 drill holes completed by Great Bear in July 2017 from which assays are pending. Highlights of historical drilling include 12.34 m of 7.54 g/t gold, and 3.82 m of 17.22 g/t gold. Great Bear has the option to purchase a 100% interest and all royalties to the Dixie Lake project for $170,000 in total payments.

The Company is similarly purchasing a 100% interest in the West Madsen gold project, with remaining payments of $58,000 over the next three years. The West Madsen project is subject to a 1.5% net smelter return ("NSR") to the underlying vendor, half of which can be bought for $500,000. Great Bear has a right of first refusal on the sale of the remaining 0.75% of the NSR.

The West Madsen project consists of two claim blocks located along the newly identified geological continuity of the Balmer assemblage greenstone belt which hosts the adjacent historical Madsen and Starratt Olsen mines. Recent logging road construction has opened the area to cost-effective exploration for the first time. The eastern block is situated 3 kilometres to the west of Pure Gold Mining's ("Pure Gold") Madsen property; each block is roughly 6 kilometres by 3 kilometres in size, for a total area of 2000 hectares.

Between the Dixie Lake project and the West Madsen project, Great Bear now controls 4400 hectares of the prospective greenstone belts which host all of the active mines and past producers in the Red Lake district.
