Jul 11, 2022 (Therese Pettigrew) - Lithologies identified in the Main and East zones of the CUC reveal several common features, the main one being a core of variably altered (mainly serpentinized) dunite, peridotite and pyroxenite which combined are referred to as the ultramafic unit (UM). Gabbroic (GAB) rocks define the northern contacts, while metavolcanic rocks (MV) of mafic/intermediate and lesser felsic composition define the southern contact. Located at either side of a main regional fault and 1 km apart, with complementary geometries, these two zones are interpreted as once being part of the same body, now displaced by a regional northwest trending fault (Staples et al., 2021).

Jul 11, 2022 (Therese Pettigrew) - The East Zone mineralogy shows that it is well serpentinized with high proportions of magnesium serpentine. Heazlewoodite appears to be the main nickel-bearing mineral in the East Zone, with lower proportions of awaruite. There does not appear to be as much pentlandite in the East Zone which is likely due to lower sulphur availability during the serpentinization process. The East Zone has the highest average concentration of magnetite (6.9%) followed by the lower-grade domains in the Main Zone and finally the Main Zone higher-grade core. The average magnetite concentration is in the range 5.3% to 6.9% across the domains. The average concentration of Cr Spinel is in the range 2.3% to 3.3%. The mineralized zone is 2 km long by 600 m wide, and east-west oriented, with mineralization open to the east and west. The East Zone has a “core” of medium-high nickel concentrations (>0.21% Ni) grading to a not as extensive “halo” of medium-low concentrations to the north and south, quickly followed by low to barren concentrations. DDH CR19-28 returned 0.24% Ni, 0.013% Co, 0.028 g/t Pd, and 0.017 g/t Pt over 321 m. DDH CR19-33 returned 0.25% Ni, 0.013% Co, 0.018 g/t Pd, and 0.008 g/t Pd over 314.6 m, including 0.42% Ni, 0.014% Co, 1.16 g/t Pd, and 0.05 g/t Pt over 3 m (Staples et al., 2021).
