TomaGold Discovers Major New Deep Semi-Massive Sulfide Zone, Intersecting 5.75% ZnEq (1.34 g/t AuEq) over 98.5 m at Berrigan Mine

Executive Summary

• Drill hole TOM‑25‑015 intersected a high‑grade semi‑massive sulfide interval 5.75% ZnEq (1.34 g/t AuEq) over 98.5 m, confirming a new deep mineralized zone (“Berrigan Deep”) that remains open at depth.
• Drill hole TOM‑25‑014 returned a notable intercept 28.69% ZnEq (6.73 g/t AuEq) over 2.10 m, extending the known vein system laterally and at shallow depth.
• The company will launch a follow‑up drilling program in early 2026 after receiving results from three pending holes (TOM‑25‑011 to TOM‑25‑013) and an EM survey, targeting the –250 to –500 m interval and further testing Berrigan Deep.

Key Details

• Hole TOM‑25‑015 (depth 451.20‑549.70 m)
• Primary intercept: 5.75% ZnEq / 1.34 g/t AuEq over 98.5 m (core length).
• Sub‑intervals include:
  • 26.67% ZnEq (6.26 g/t AuEq) over 4.90 m (452.20‑457.10 m)
  • 7.26% ZnEq (1.69 g/t AuEq) over 49.35 m (500.35‑549.70 m)
  • 10.26% ZnEq (2.39 g/t AuEq) over 14.60 m (521.00‑535.60 m)
  • 9.94% ZnEq (2.31 g/t AuEq) over 3.25 m (537.85‑541.10 m)
  • 14.82% ZnEq (3.45 g/t AuEq) over 6.20 m (542.00‑548.20 m)
• Hole TOM‑25‑014 (depth 185‑187.10 m) – 28.69% ZnEq / 6.73 g/t AuEq over 2.10 m; additional intervals at 238.70‑239.85 m, 251.20‑252.60 m, 405.30‑406.70 m, and 423.30‑426.30 m with ZnEq ranging from 1.34% to 41.79%.
• Geology & Mineralogy (TOM‑25‑015) – Semi‑massive to massive sulfides (sphalerite, pyrrhotite, chalcopyrite, galena) within serpentinized peridotite; strong shearing/fracturing control; breccia and fault mud at 583.75‑586.70 m suggest system remains open deeper.
• Pending Results – Intercepts for holes TOM‑25‑011, TOM‑25‑012, TOM‑25‑013 and EM survey expected early February 2026.
• Planned Follow‑Up Program – To commence after pending results; focus on extending Berrigan Deep and testing the –250 to –500 m interval across the northern sector of the camp.
• Webcast – Company hosted a live webcast on 29 Jan 2026 (4:00 pm ET) presenting these results, led by President & CEO David Grondin.
