Project Summary
The Brassy Project consists of four non-contiguous claims totalling 12,076 hectares in the northern Athabasca Basin. The claims are underlain by Athabasca Group sandstones, with variable thicknesses to a max of around 200 metres; the eastern claim has some portions with no sandstone cover. Historical geophysical and geochemical work was completed between 1969 and 1983, followed by modern EM, magnetic, radiometric and gravity surveys between 2005 and 2011. No modern ground exploration has been completed to date except for a small prospecting program covering part of the eastern claim in 2015.
The Brassy project remains completely untested by drilling, however historical drilling along strike in the Newnham Lake area (between the eastern and western claim blocks) encountered intense faulting, strong hydrothermal alteration, and visible uranium mineralization. Multiple holes drilled by SMDC (now Cameco) in the late 1970’s and early 1980’s encountered uranium mineralization; the best results included 2.2 m of 0.05% U3O8 including 0.87 m of 0.10% U3O8 in BL-146, 0.5 m of 0.09% U3O8 in BL-172, and 0.3 m at 0.10% U3O8 in BL-090. More recent drilling by ALX Uranium in 2018 encountered an interval of unconformity-hosted uranium, returning 0.035% U3O8 over 5.7 m, including 0.118% U3O8 over 0.5 m, in drill hole NL18-001. The conductors and associated magnetic low associated with the mineralization at Newnham Lake trend onto the Brassy project and are a high priority for future follow-up.
