North Bay Resources Reports Assays up to >25% Mg, 0.1% Ni, 0.1% Cu, 0.01% Co, 0.3 ppm Pt at Tulameen Platinum Project, British Columbia
Concentrations of chrome spinel and massive chromitite appear to be distributed randomly throughout the dunite as discrete layers, nodular masses and schlieren.
- Concentrations of chrome spinel and massive chromitite appear to be distributed randomly throughout the dunite as discrete layers, nodular masses and schlieren.
- Associated with chromite are microscopic grains of platinum minerals (platinum -iron alloys, sperrylite), nickel iron sulphides (pentlandite, violarite, bravoite), chalcopyrite and pyrite (St. Louis et al.
- This occurrence is hosted in the dunite-rich core of the Early Jurassic Tulameen Ultramafic Complex, a zoned Alaskan-type intrusive complex.
- Mineralization occurs in a serpentine breccia zone containing fragments of dunite / peridotite cemented by a matrix of serpentine.
