The Winter 2010 drilling at Collins Bay Extension was stopped on April 10, but was able to test a uranium mineralized target on Fife Island, and then advance to a second, large, well-defined conductivity and gravity anomaly target located due east of the Collins Bay-Eagle Point mine area.
In this last target, CanAlaska intersected a new geological feature with uranium mineralization and extensive breccia development. Additional holes were not able to be completed, due to the conditions of the ice on Lake Wollaston.
Four holes were drilled on Fife Island for a total of 539mt to test the ‘Vic Zone’. Three of the drill holes tested a drill intersection of 0.152% U(3)O(8) over 4mt at a faulted contact of graphitic metapelite with Archean basement gneiss.
The first three drill holes targeted the approximate location of the intersections as well as 20mt above and below to test the continuity of this type of mineralization. The fourth drill hole at Fife Island targeted another intersection. This drill hole showed strongly-fractured and favorable rock from top to bottom, but was lost at 89mt depth.
The Blue Island target, which is lake-covered, was identified from the VTEM airborne geophysical survey completed in 2007. Drilling commenced on the Blue Island target in mid-March. However, the drilling contractor was unable to complete the first hole on this target, CBX005, and the hole was abandoned.
A second drill contractor, Driftwood Diamond Drilling was able to commence testing the target in early April, and completed the first of three planned holes, before having to leave the site due to warm weather conditions and failing ice.
A ground geophysical Max-Min survey was completed over the Fife Island target during the winter program. This survey identified the conductive sedimentary package which trends north-northeast in this area. Over the winter exploration season, CanAlaska operated with six drill rigs in the field.
