Canadian North Resources Inc. announced the findings from the analysis of Borehole Time-Domain Electromagnetic (BHTEM) surveys conducted on deep West Zone drillholes FL22-481A and FL23-481B at its wholly owned Ferguson Lake Project in Nunavut, Canada.

The combination of the drilling and geophysical survey results confirms the continuing high-grade prospectivity of the West Zone down-dip for over 200 m at depths of 650 to >850 m. Further geophysical modeling is ongoing to define precisely new drill targets for follow-up in 2024.

As previously reported, the two geophysically surveyed drill holes intersected excellent widths of high-grade Cu-Ni-Co-PdPt massive sulfide as well as additional down-hole widths of footwall low sulfide PGE-type mineralized sections. These results are shown in the table below. They were drilled from the same site during the exploration programs of 2022 and 2023.

When the drilling results were spatially interpreted, it was discovered that FL22-481A intersected the zone about 80 to 100 m down-dip from previous West Zone horizon intersections, and FL22-481B intersected the zone 100 to 140 m farther down-dip from the FL22-481A pierce points through the mineralization. This generally extends the West Zone at this location down-dip by more than 200 m.
While the drilling program was in operation in the late summer of 2023, BHTEM surveys were finished on each of these holes. The surveys were specifically designed to minimize signal interference from the known up-dip major mineralized horizon by concentrating on measuring lateral and down-dip electromagnetic anomalies.
Multiple strong electromagnetic conductors were found in the holes, according to processed findings. According to preliminary interpretations, the first two sulphidic junctions for both holes were linked to highly conductive electromagnetic responses. These responses were observed to degrade to off-hole anomalies at late time domains, producing vectors to several centers of greater conductivity off-hole.
