Deep Semi Massive Sulphide Zinc, Silver and Gold Intersection at Berrigan Property

ROUYN-NORANDA, Quebec, Jan. 29, 2026 (GLOBE NEWSWIRE) -- Chibougamau Independent Mines Inc. (CBG-TSXV in Canada, CLL1-Frankfurt, Stuttgart, Berlin and Lang & Schwarz Stock Exchanges in Germany, CMAUF-OTC in the US), herein called Chibougamau, is pleased to update shareholders as regards recent drilling reported by TomaGold Corporation (LOT-TSXV, TOGOF-OTCPK) on the Berrigan property located west of the town of Chibougamau, under option from Chibougamau Independent Mines Inc. Updated option terms were published in a Chibougamau Independent press release dated September 30, 2025 accessible by clicking here.

Tomagold has published assay results for two drill holes TOM-25-015 and TOM-25-014 as follows:

• Drill hole TOM-25-015 (from 451.20 m): 5.75% ZnEq (1.34 g/t AuEq) over 98.5 m
  • Including: 26.67% ZnEq (6.26 g/t AuEq) over 4.90 m
  • Including: 7.26% ZnEq (1.69 g/t AuEq) over 49.35 m
  • Including: 10.26% ZnEq (2.39 g/t AuEq) over 14.60 m, 9.94% ZnEq (2.31 g/t AuEq) over 3.25 m, and 14.82% ZnEq (3.45 g/t AuEq) over 6.20 m
• Drill hole TOM-25-015 confirms the discovery of a new major semi-massive sulfide zone, named Berrigan Deep, which remains open at depth 
• Drill hole TOM-25-014 (from 185 m): 28.69% ZnEq (6.73 g/t AuEq) over 2.10 m

Tomagold states that “Drill hole TOM-25-015, grading 5.75% ZnEq (1.34 g/t AuEq) over 98.5 m, is truly transforming the Berrigan Mine project and highlights a new semi-massive sulfide zone that extends at depth beneath the known zones. This very encouraging result suggests the presence of a large mineralized system that remains open at depth.”

The drill holes contain significant secondary silver and gold mineralization. The table below provides the breakdown of individual assays.

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.
• ZnEq and AuEq are calculated using the Company’s standard parameters.
• AuEq calculation was based on US$4150/oz Au, $51.36/oz Ag, US$5.044/lb. Cu and $1.398/lb Zn. AuEq = Au g/t + (Ag g/t × 0.01237) + (Cu ppm × 0.000083) + (Zn ppm × 0.000023). The use of AuEq is to calculate cut-off grades for exploration purposes, and no adjustments were made for metal recovery. The Company is currently in the initial exploration phase, following historical drilling. At this stage, the Company does not have any metallurgical data and no comparative studies have been conducted, given the geological complexity of the ultramafic host rock. Furthermore, the Company is not aware of any deposits that may have similar geological characteristics.
• ZnEq calculation was based on US$4047/oz Au, $50.22/oz Ag, US$4.796/lb. Cu and $1.390/lb Zn. ZnEq = Zn ppm + (Ag g/t × 527) + (Au g/t x 42466) + (Cu ppm × 3.45) / 10,000. The use of ZnEq is to calculate cut-off grades for exploration purposes, and no adjustments were made for metal recovery. The Company is currently in the initial exploration phase, following historical drilling. At this stage, the Company does not have any metallurgical data and no comparative studies have been conducted, given the geological complexity of the ultramafic host rock. Furthermore, the Company is not aware of any deposits that may have similar geological characteristics.
