Canada Nickel Company Inc. has announced an updated mineral resource estimate (MRE) for its 100% owned Crawford Nickel Sulphide Project near Timmins, Ontario, more than doubling the project’s measured and indicated (M&I) mineral resources.
Mark Selby, Chair and CEO said: “We are very pleased with our continued exploration success at Crawford. Our overall M&I resource has more than doubled, driven in large part by outstanding exploration success in our East Zone. In less than three years from initial discovery, we believe Crawford has quickly become the fifth largest nickel sulfide resource globally. When combined with the potential for zero carbon production, Crawford is expected to become an important source of nickel for electric vehicle and stainless-steel producers. With additional potential from a number of holes still pending assays at the resource cut-off date, we expect the final feasibility study resource to support the upper end of our mine plan target of 1.3 – 1.8 billion t. The Crawford feasibility study continues to be on track for completion by year-end.”
Crawford MRE update
Total M&I resources more than doubled to 1.43 billion t at 0.24% nickel (Ni) and inferred resource was 0.67 billion t at 0.23% Ni. The East Zone M&I resource increased by more than 14-fold to 701 million t at 0.23% Ni and the Main Zone resource increased by 17% to 724 million t at 0.25% Ni. With 3.48 million t of contained nickel in M&I resources, the company believes Crawford has the fifth largest contained nickel sulfide resource globally. M&I resources also include 93.9 million t of iron, 8.5 million t of chromium, 183 000 t of cobalt, and 1.06 million oz of palladium and platinum.
This updated resource is based on a combined total of 113 drillholes and 56 286 m of drilling. Consistent with previously reported resources, a cut-off grade of 0.15% Ni was used in the MRE. 60% of assays from 54 additional exploration drillholes in the East and Main Zone that had not yet been received as of the resource cut-off date will be subsequently incorporated into the final feasibility study resource. Given the focus on the Main and East Zone as resources for this phase of the feasibility study, resources for North Zone (15 drill holes) and Western Extension (38 drill holes) are expected to be completed later this year and incorporated into the final feasibility study.
This MRE was prepared by Caracle Creek International Consulting Inc. in accordance with CIM Definition Standards on mineral resources and reserves. The MRE is effective as of 6 July 2022.
Drilling completed during 2021 and early 2022 joined the two previously isolated sections of mineralisation. The updated resource, consisting of a total of 47 drill holes and 22 563 m, extended the resource by 500 m to the east for a total of 2.6 km in strike length, up to 350 m in width, and more than 650 m deep. Drilling extended mineralisation a further 200 m to the east and mineralisation remains open at depth. Higher grade mineralisation continues at depth beyond the current resource, as tested by hole CR22-230 which was completed to a depth of 1155 m. Assays for this hole are pending.
Drilling in the Main Zone focused near the west extension as well as testing the continuation of higher-grade targets at depth. The Main Zone resource now consists of a total of 66 drillholes and 33 723 m of drilling and is defined across strike length of 1.9 km, a width of up to 580 m and 700 m deep. Higher grade mineralisation continues at depth beyond the current resource as tested by hole CR22-198 which was completed to a depth of 1044 m. Assays for this hole are pending.
