Highrock East Project

The Highrock East Project consists of one claim covering 5714. 2 Ha approximately 19 km southeast of Cameco’s Key Lake operation. The project is underlain by Wollaston Group metasedimentary gneisses, predominantly psammitic to meta-arkosic in composition but with localized prospective pelitic to psammopelitic gneisses. Despite lying outside the current extent of the Athabasca Basin, the Highrock East project was covered by the Athabasca Supergroup in its past, making the area prospective for unconformity-related uranium mineralization.

Exploration work on the project is primarily historical in nature and consists of airborne EM, magnetic, and radiometric surveys, prospecting, lake water and sediment sampling, radon surveys, geological mapping, and diamond drilling in the late 1960’s to early 1980’s, prior to modern geophysical surveys and the development of modern exploration models. Several anomalies were discovered during radon sampling on the project, which were followed up by drilling in 1978. The drilling on the project consisted of 5 shallow (<152 m) holes which intersected Wollaston Supergroup metasedimentary rocks. These rocks comprised meta-arkose and semipelitic to pelitic gneisses, as well as amphibolite and pegmatite to granodiorite, along with localized hematite, chlorite, epidote, and/or goethite alteration. A weakly radioactive pegmatite was intersected in hole 78-1 which returned 0.025% U3O8 over 0.45 m at a depth of 72.85 m (AF 74H03-0036). A limited amount of prospecting was completed in the area in 2008 and led to the discovery of an outcrop of pegmatite on the property which contained 181 ppm U, 205 ppm Nb, and 39 ppm Ta (SMDI 5179). The project has otherwise been unexplored since the 1980’s and is prospective for intrusive-type and unconformity-related uranium deposits.
