Canada Nickel Company Inc. has announced the results from the infill drilling programme at its Crawford Nickel-Sulphide Project, which included the discovery of a higher-grade core in the East Zone. The East Zone has now been successfully tested for 2.1 km of its overall 3.2 km interpreted strike length.
- Infill drilling identified an extensive higher-grade core in the East Zone, similar to the Main Zone.
- The higher-grade cores span combined strike length of 1.6 km, a width of 20 – 50 m, to a depth of 690 m.
- Drilling in the East Zone has successfully infilled and extended strike length to a total of 2.1 km, substantially larger than previously reported resource.
- Hole 142A averaged 0.31% nickel (Ni) across its entire 576 m core length, ending in mineralisation. Hole 165A (assays pending) was mineralised across its entire 690 m core length, ending in higher grade mineralization at 735 m. Five other holes recently completed intersected drill intervals of up to 216.6 m of higher-grade mineralisation.
- Samples from East Zone Higher Grade Core yielded the highest grade concentrate from Crawford during metallurgical work reported for the previously released preliminary economic assessment with 43% of the recovered nickel reporting to a 55% nickel concentrate.
Mark Selby, Chair and CEO, commented: “The East Zone is becoming a significant resource. The most recent infill and expansion drilling at the Crawford East Zone continues to confirm our target of increasing the East Zone resource by 2 – 3x and the identification of an extensive higher-grade core, similar to the Main Zone, has been an exciting development. This East Zone core has yielded intervals of both high-grade nickel and PGMs and the latest two holes (CR21-142A, CR21-165A), which were drilled to test this higher-grade mineralisation at depth, remained in higher-grade mineralisation to the end of each hole at 624 and 735 m deep respectively – more than 100 m below the current resource. I look forward to the resource update on the Main, East, and North zones next year to support the feasibility study expected to be delivered later in 2022.”
Crawford East Zone
In the East Zone, an additional six holes have assays reported, a further 22 holes have been drilled with assays pending. Infill drilling is expected to continue for the balance of the current year to contribute to the resource update next year that will support the feasibility study. Infill drilling, deeper drilling, and drilling beyond the resource outline along strike have all demonstrated continuity for a distance of 2.1 km.
The Higher Grade Core was identified during a drill programme intended to expand the current resource and was present in previous holes (CR20-28, CR19-31, CR20-33, CR20-34, CR20-35, CR20-36, CR20-37, CR20-39, CR21-112) but was thought to be discontinuous. Additional drilling is consistent with the company’s belief that this core is more continuous and centred along the East Zone, much like the higher-grade core of the Main Zone. This higher-grade Core remains open at depth and along strike.
