CanAlaska Uranium Ltd. ("CanAlaska" or the "Company") announced that it has intersected polymetallic mineralization at the unconformity on its Waterbury South uranium project. The program was designed to test targets near previously drilled holes, which show significant alteration and uranium values, in proximity to untested geophysical targets. The program consisted of 1,347.5 metres of drilling in three drill holes. CanAlaska drill holes WAT-008 and WAT-009, tested the main target near failed Cameco drill hole SOD-253. Cameco's hole failed due to strongly faulted and altered sandstone above the unconformity. CanAlaska Geologist at Waterbury South ProjectIn the new 2021 drill holes completed by CanAlaska, bleaching is present through much of the sandstone column, becoming more intense in the lower half of the sandstone as the holes neared the unconformity. In WAT-008, a pyrite-rich zone associated with a fault in the mid-sandstone column well above the unconformity contained anomalous nickel, arsenic, cobalt and zinc values. A thick graphitic unit was intersected in the lower section of the hole that provided a clear target at the unconformity for drill hole WAT-009. In WAT-009, bleaching is present over the last 100 metres of the sandstone column with an increase in sooty pyrite alteration above the unconformity, which correlates with the sooty pyrite noted in the lower 50 metres of SOD-253. A seven (7) metre long structure of broken rock with intense clay alteration and hematization occurs 20 metres below the unconformity and correlates with a fault structure in the sandstone at 138 metres depth in drill hole SOD-253. Much of the basement in WAT-009 is clay altered and chloritized indicating the presence of a large hydrothermal event. A 3.3 metre zone of intense clay alteration straddling the unconformity in WAT-009 contains significant polymetallic mineralization consisting of 0.5 metres with 405 ppm uranium, 2.42% nickel, 2.34% arsenic, 0.5% zinc, and 801 ppm cobalt. This mineralization association, or fingerprint, is directly reminiscent of metal associations at the nearby Cigar Lake orebody where similar values of nickel, arsenic and cobalt are known to exist with the high-grade uranium.
