Diamond Drilling Reveals Copper Mineralization at Tribag Mine Zone

Stone Gold Inc. reports that Phase 1 diamond drilling in the Breton Breccia at the old Tribag Mine Zone on the 21,000-hectare Copper Road Project, situated approximately 80 kilometers north of Sault St. Marie, Ontario, Canada, has discovered copper mineralization.

TR22-001, 000AZ, -80 dip, 380 m depth, the first 100 meters is a fractured, well-indurated, modified granite that progressively becomes more brecciated as it progresses to the bottom of the hole at 380 m. A total of 144 samples covering the bottom section of the hole have been extracted and presented for analysis.

The brecciation, predominantly disseminated pyrite sulfides, and sampling continues to the hole’s terminus, showing no signs of intensity reduction. Other sulfide mineralization includes rare galena, probable stibnite needles, and microscopic specks of chalcocite, in addition to chalcopyrite.

TR22-002, 045AZ, -70 dip, 255.8 m depth, substantially more sulfides were noted in TR22-002 than in 001, varying from 5–10% throughout the first 50 m and last 50 m, surpassing 15% in the first 50 m and last 50 m. Traditional polymictic Breccia with rounded 5 to 20 cm mafic and porphyritic felsic clasts with quartz flooding injections throughout, Breccia intermittently cut-up by 1-2 meter mafic dykes, and larger granite fragments.

Sulfides are primarily pyrite of various colors, with 2% chalcopyrite blebs forming blebby disseminations and filling fractures, and specks of galena, chalcocite, and bornite. At the beginning and near the end of the hole, numerous 3-6 cm diameter chalcopyrite clumps were found. For sampling, the entire hole has been laid out.

Till now, TR22-003, 030AZ, -70 dip, 305 m depth: the hole is 10 m beneath TR22-002. The lithology and mineralization dispersion in the core seems to be identical to that of 002, with the exception that the intensity of Cu mineralization tends to rise towards the bottom in 003, with an 8 cm piece of massive chalcopyrite at around 300 m depth.

Holes 1 and 2 from the first drill program in 50 years at the Breton Breccia are currently at the assay lab. Drilling has re-commenced on Hole #3 to test directly under the center of the Breton Breccia which was not historically mined. Our goal is to establish copper mineralization at the Breton Breccia, which is one of six known breccias in the Tribag Zone.

The Tribag Zone is the first of three mineralized zones to be drill tested across the 21,000 hectare Copper Road Project which contains two past producing copper mines,” Timmons added.

Dr. Trevor Boyd, P. Geo., and a Qualified Person for technical data under NI 43-101 criteria have vetted and approved the facts in this press release.
