Drilling Resumes on Berrigan Zinc, Gold, Silver Property under Option from Chibougamau Independent Mines

ROUYN-NORANDA, Québec, March 31, 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) has started a drill program to extend 5 recent drill holes in order to intersect a newly recently discovered zinc/gold/silver zone intersected beneath the previously known Berrigan mineralized zone.

The Berrigan property is a part of a large land package under option from Chibougamau Independent Mines as announced in a press release dated August 14, 2023 and accessible here.

The five drill hole extensions are planned to intersect the horizon where previous drill hole TOM-25-015 intersected 5.08% Zn Eq (1.19 g/t Au Eq) over 98.50 m, including 23.20% Zn Eq (5.44 g/t Au Eq) over 4.90 m.

Drilling from the previous phase of Tomagold drilling returned significant mineralized intersections as listed below.

• 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.
