Geology
Larocque East was purchased in May 2018 and subsequently expanded through staking. The property covers a 15-kilometre-long northeast extension of the Larocque Lake conductor system; a trend of graphitic metasedimentary basement rocks that is associated with significant uranium mineralization in several occurrences to the southwest of the Larocque East property. The closest of these are the Larocque Lake and Larocque North zones, which are located 6.5 kilometres and 0.4 kilometres, respectively, to the southwest of the western Larocque East property boundary. Drilling at the Larocque Lake zone has returned historic intersections of up to 29.9% U3O8 over 7.0 metres in drill hole Q22-040. Drilling at the Larocque North zone has returned intersections of up to 2.05% U3O8 over 0.8 metres in drill hole Q22-16.
Larocque East is located adjacent to the Wollaston-Mudjatik transition zone - a major crustal suture related to most of the major uranium deposits in the eastern Athabasca Basin. Importantly, the sandstone cover is thin, ranging between 140 metres and 330 metres in previous drilling. A total of 42 historical drill holes have been completed on the property along approximately 22 kilometres of graphitic conductors. Five historical drill holes have intersected weak uranium mineralization on the Larocque East property to date, including drill holes KER-07 (0.12% U3O8 over 0.1 metre) and KER-11 (0.06% U3O8 over 0.5 metre) near the western property boundary, within the general vicinity of 2018 discovery drill hole LE18-01A.
