CanAlaska Completes Initial Drilling at Waterbury

First holes contain encouraging fault structures and alteration

Thick graphitic basement package intersected

Vancouver, Canada, April 21, 2021 CanAlaska Uranium Ltd. (TSX-V: CVV; Frankfurt: DH7N) (“CanAlaska” or the “Company”) has curtailed winter drilling on its 100%-owned Waterbury uranium project. Late permitting and warming weather conditions hampered activities. Only half of the planned winter program was completed. Three drill holes, were completed on the South claim, and none on the East. The focus was to test targets near previously drilled holes which showed significant alteration, uranium values and untested geophysical targets on both the East and South Waterbury claims.

The target on the Waterbury South claim is close to the interpreted location of the regional Rabbit Lake – Collins Bay fault system, host to the Rabbit Lake, Collins Bay and Eagle Point uranium orebodies (Figure 1).

One hole targeted the unconformity one kilometre northeast of drill hole SOD-253 where a resistivity anomaly from a survey completed by CanAlaska highlighted a distinct unconformity breach style anomaly above the basement conductor (Figure 2).  The drillhole located a thick graphitic sequence in the basement and graphitic faults associated with anomalous alteration overprint. The ideal unconformity target related to these structures and alteration remains untested at this stage.

A further two holes tested the unconformity for 150 metres southeast of failed Cameco drill hole SOD-253 and found the basement structures that were the focus of that program.  The historic drillhole been abandoned above the unconformity in a faulted and altered section of Athabasca sandstone. CanAlaska’s new drillholes passed though the sandstone and intersected a thick sequence of graphitic rocks in the basement.  Notably the basement has a zone of strong faulting, and wide sections of very intense alteration consisting of clay, secondary hematization, and dravite, which together are prime signatures of fluid flow associated with uranium mineralizing events in the Athabasca region.

Core samples were collected and sent to the Saskatchewan Research Council (SRC) for geochemical analysis. Samples for clay analysis are currently being processed.

President Peter Dasler commented: “the drill team has confirmed the geophysical interpretation of strongly altered basement and sandstone with underlying reactive graphitic sediments. These are a very encouraging features for us to focus our next drill program at Waterbury South.  It is unfortunate that timing and weather did not allow further holes this season, however we have significantly upgraded the current target at Waterbury south, and look forward to getting another chance for discovery.”
