Lithology Comments

Oct 22, 2009 (A Wilson) - The mineralization is hosted within zones of quartz-pebble conglomerate of the Matinenda Formation. A uraniferous zone in sediments along the Quirke syncline is thought to be 15,000' x 4,000' x 36'. Diabase intrudes the sedimentary rocks.

Mineralization Comments

Oct 22, 2009 (A Wilson) - Assay for DDH 150-2 returned 0.09% U3O8 and 0.01% ThO2 over 1 foot (estimated 0.5 lbs ThO2 over 8 feet). DDH KM-156-5 returned 0.65 lbs U3O8 per ton (0.33 kg/t) over 34 ft (10.4 m). DDH KM-150-5 returned 0.88 lbs U3O8 per ton (0.44 kg/t) over 44 ft (13.4 m). DDH KM-150-2 returned 0.68 lbs U3O8 per ton (0.34 kg/t) over 11 ft (3.4 m)


Jun 03, 2022 (Therese Pettigrew) - Mineralization consists primarily of detrital grains of brannerite and uraninite, together with minor uranothorite, monazite and secondary coffinite associated with pyrite, pyrrhotite, zircon, rutile and Ti-magnetite as interstitial fill in a quartz pebble conglomerate. The main ore mineral is brannerite, containing small inclusions of pyrrhotite and radiogenic galena, and occurring as ovoid, reddish-brown grains associated with bladed rutile surrounded by uranium oxides and rare earth oxides. The second most important ore mineral is uraninite which occurs as black subhedral grains up to 0.1 mm in size containing approximately 6% ThO2 by substitution. Monazite is a lesser ore mineral which contains an unusually high uranium content as inclusions (also uranothorite or thorite) - occurs as rounded to subangular grains typically less than 0.3 mm in diameter. Pyrite content is typically 10-15% of the rock (Robertson, 1981) which only rarely occurs as fracture fillings; also occurs as inclusions in monazite. Uranothorite and coffinite have been identified as minor mineral phases. Non-metallic gangue minerals in the matrix of the conglomerate are represented by quartz, feldspar and sericite. In some mines a dark grey to black hued ore is reported to contain fine grained chlorite. Thucholite, an organo-uranly compound (U-bearing radioactive bitumen), occurs locally as thin laminae and as a void-filling mineral phase within ore zones at Elliot Lake (Workman et al., 2013).
