Chibougamau updates drilling at Berrigan mine

Update on Drilling on Chibougamau’s Berrigan Mine Asset ROUYN-NORANDA, Québec, May 29, 2026 (GLOBE NEWSWIRE) -- Chibougamau Independent Mines Inc. (CBG-TSX-V in Canada, CLL1-Frankfurt, Stuttgart, Berlin and Lang & Schwarz Stock Exchanges in Germany, CMAUF-OTC in the US),  herein called Chibougamau, is pleased to report that Tomagold Corporation (LOT-TSXV, TOGOF-OTCPK) has provided an update as regards recent drilling on the Berrigan Mine claims in the Chibougamau area of Quebec. The Berrigan Mine claims and a large number of others are under option from Chibougamau Independent Mines Inc. as updated in a CBG press release dated 2025-09-30. Previous Phase 1 drilling intersected the historical Berrigan Mine mineralization but also in two drill hole TOM-25-015 and Tom-25-014 intersected 5.08 ZnEq (1.19 g/t AuEq over 98.5 m including 23.20% ZnEq over 4.90 m from the new lower zone and 24.85% ZnEq (5.83 AuEq) over 2.1 m in the Berrigan zone and 13.68 ZnEq (3.17 g/t AuEq) in the new lower zone respectively as reported in TomaGold’s.

See “Notes” below for basis of grades calculation. Table 1: Results from drill holes TOM-025-14 and TOM-025-15 on the Berrigan Mine project Notes: The reported widths represent core lengths. True width is estimated to be approximately 80-85% of the core length, depending on the deviation angles.

Phase 2 drilling was focused upon extending 5 drill holes TOM-25-009 to TOM 25-013 inclusive in order to intersect the new zone as the previous drilling was focused upon the historical shallower mineralization. In TomaGold’s press release dated 2026-05-28 , Tomagold reports: “ The program, which focused on extending drill holes TOM-25-009 through TOM-25-013, was designed to test the core of modelled conductive plates at depth and evaluate the potential of the Berrigan Deep zone, discovered just before Christmas (see Figure further below).
