Province: Superior
Subprovince: Abitibi
Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Neoarchean
Jul 08, 2022 (Therese Pettigrew) - The property lies in the Abitibi greenstone belt, within the Wawa-Abitibi Terrane (Stott et al., 2011) of the Archean Superior province. The Abitibi greenstone belt, 650 km long and up to 150 km wide, is the largest such belt in the Canadian Shield. Its history of volcanism, sedimentation, intrusive magmatism, tectonism, deformation, metamorphism and mineralization evolved between 2.8 and 2.6 Ga. Crawford Township is underlain by mafic, intermediate and felsic metavolcanics striking between east-west and WNW-ESE. A number of interflow sedimentary units are present including graphitic and sulphidic sediments. A number of faults with apparently significant strike-slip displacement have been interpreted from offsets of trends on the magnetic survey. These faults trend in either the NNE-SSW or ENE-WSW directions (Assessment report 20000018611).

Jul 08, 2022 (Therese Pettigrew) - The Crawford Ultramafic Complex is entirely under cover but based on geophysics and drilling is an approximately 8.0 km long by 2.0 km wide body of dunite, peridotite (and their serpentinized equivalents), and lesser pyroxenite and gabbro. Descriptions from drill core logs record localized brecciation in the Main Zone at the northern contact between mafic volcanic rocks and dunite (Staples et al., 2021).

Dec 07, 2005 (A Wilson) - The best assay returned 0.40% Ni and <0.05% Cu over 15.0 ft.
Jul 08, 2022 (Therese Pettigrew) - Sulphide mineralization discovered to date in the project area can be characterized as Komatiite-hosted Ni-Cu-Co-(PGE) deposit type, particularly the Mt. Keith sheet flow style. Diamond drilling has outlined a west-northwest trending (~285-315Az) ultramafic body (largely dunite-peridotite) that is at least 1.8 km in strike length, 200 to 250 m in width, and more than 650 meters deep. A north-northwest trending regional sinistral, strike-slip fault terminates the ultramafic body along its southeastern extent. The following minerals were identified as carrying most of the nickel and cobalt (in order of decreasing abundance): pentlandite (50%: iron-nickel sulphide), heazlewoodite (35%: sulphur poor, nickel-rich sulphide), awaruite (15%: nickel-iron alloy) and minor godlevskite (nickel-iron sulphide). Crawford has low levels of pyrrhotite across the Main and East zones. The highest concentrations of pyrrhotite are in the higher-grade core of the Main Zone. INCO drill hole 25050 (-55°) returned the best results, with 0.240% Ni over a core length of 467.56 m, which represented the entire length of the hole, from the bedrock surface at 34.75 m to the end of hole at 502.31 m. This included 355.1 m of 0.272% Ni, which in turn included 132.9 m of 0.342% Ni. Individual assays, mostly of 4.56 m (15 feet) ranged up to a maximum of 0.44% Ni. INCO drill hole 27095 (-45°) was a shallower hole at 273.4 m, but returned an average of 0.341% Ni over 236.22 m, again the entire length of the hole in bedrock. Drill hole 27086 (-45°) was collared in gabbro and entered peridotite that carried lower nickel values; the best assay was 0.20% Ni over 4.56 m. Drill hole 27005 was collared in peridotite with an average of 0.185% Ni over 122.26 m, before entering mafic volcanics. DDH CR18-01 returned 0.293% Ni, 118 ppm Co, 11 ppb Pt, 20 ppb Pd, and 2 ppb Au over 291 m. DDH CR18-03 returned 0.299% Ni, 140 ppm Co, 28 ppb P5, 55 ppb Pd, 6 ppb Au over 130.50 m. DDH CR18-04 returned 0.332% Ni, 135 ppm Co, 10 ppb Pt, 27 ppb Pd, 2 ppb Au (Staples et al., 2021).
