BISHOP, Calif., May 29, 2024 (GLOBE NEWSWIRE) -- North Bay Resources Inc. (the “Company” or “North Bay”) (OTC: NBRI) is pleased to announce it has received assays from recent exploration conducted at its wholly owned Tulameen Platinum Project, British Columbia (the “Property”). Nine rock samples, analyzed using Aqua Regia - ICP whole rock analyses (ME-ICP41) at ALS Global Laboratory, North Vancouver, BC from exploration conducted in April of 2024, confirmed a magnesium hosted nickel-cobalt deposit with copper and platinum group metals. The property is known to host a large magnesium deposit consisting of olivine within a dunite core, a common host rock and indicator for nickel and other metals and gems. A historic resource by Diamet in the 1980’s estimated 15,000,000 tons of dunite in a single zone, primarily in the form of olivine (magnesium). There have been 4 additional zones identified.

Tulameen Geology
The dunite rock is principally made of forsteritic (magnesium rich) olivine, accessory chromite, and rare diopside. The rock is medium to dark grey, buff weathering and well jointed. The serpentinized (altered) dunite rocks contain serpentine, carbonates, magnetite, and talc. Concentrations of chrome spinel and massive chromitite appear to be distributed randomly throughout the dunite as discrete layers, nodular masses and schlieren. Chromitite schlieren are commonly distinguished in outcrop by a pale alteration halo. 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. 1986).
Three main zones have been identified as follows:
Creek Zone
The Creek Zone (Minfile 092HNE128) platinum-chromite showing occurs at the confluence of Britton (Eagle) Creek with the Tulameen River. 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. The zone is 560 ft. long, up to 480 ft. wide and lies mostly north of the river, on either side of the creek. Further work, considers it as being 1,860 ft. in length (AR 17170). Chromite occurs in the breccia and the surrounding dunite in areas of stronger magnesium alteration, mostly along Britton Creek.
