ROUYN-NORANDA, Québec, Sept. 30, 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 to shareholders that TomaGold Corporation (LOT-TSXV, TOGOF-OTCPK) have reported the results from the final three, Phase 2 drill-hole extensions at the Berrigan Mine Project in the western portion of the Chibougamau Mining Camp. These 3 drill holes extensions are the final of a 5-hole program which has succeeded in “highlighting a thick extensive polymetallic hydrothermal system”, extending the Berrigan Deep Zone for a strike length of 250 m and 400 m vertically with intersections to a vertical depth of nearly 900 m.

Highlights from the drilling include:Hole TOM-25-012EXT: 69.40 m grading 3.46% ZnEq (0.81 g/t Au Eq) from 784.20 m to 853.6 m including 40.1 m grading 5.38% ZnEq (1.25 g/t AuEq) from 784.0 m to 824.3 m Hole TOM-25-010EXT: 19.1 m grading 2.23% ZnEq (0.52 g/t AuEq) from 472.4 m to 491.5 m Hole TOM-25-013EXT: 7.0 m grading 2.21% ZnEq (0.52 g/t AuEq), including 28.25 g/t Ag from 631.5 m to 638.5 m. Previous intersections in the Berrigan Deep Zone include the following:Hole TOM-25-015: 98.50 m at 5.08% ZnEq (1.19 g/t AuEq) from 451.20 m to 549.70 m,including 4.90 m at 23.20% ZnEq (5.44 g/t AuEq) from 452.20 m to 457.10 m. Hole TOM-25-011EXT:204.25 m at 2.05% ZnEq (0.48 g/t AuEq) from 553.90 m to 758.15 m, including 2.40 m at 31.31% ZnEq (7.38 g/t AuEq) from 554.40 m to 556.80 m. Note: for details on equivalent grades see Table 1 below.

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$4,150/oz Au, $51.34/oz Ag, US$5.023/lb Cu and $1.392/lb Zn. AuEq = Au g/t+ (Ag g/t × 0.01237) + (Cu ppm × 0.000083) + (Zn ppm × 0.000023), applying metallurgical recovery factors of 95% for zinc, 85% for gold and silver, and 90% for copper, based on a metallurgical report on Berrigan Mine zinc material prepared by Process Research Associates Ltd. in February 2002 and on recoveries from nearby deposits for gold, silver and copper.ZnEq calculation was based on US$4,047/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, applying metallurgical recovery factors of 95% for zinc, 85% for gold and silver, and 90% for copper, based on a metallurgical report on Berrigan Mine zinc material prepared by Process Research Associates Ltd. in February 2002 and on recoveries from nearby deposits for gold, silver and copper.
