Drilling Resumes on Berrigan Zinc, Gold, Silver Property under Option from Chibougamau Independent Mines
MWN-AI** Summary
Chibougamau Independent Mines Inc. (CBG-TSX-V) has announced that TomaGold Corporation (LOT-TSXV) has commenced an important drill program at the Berrigan zinc, gold, and silver property located in Rouyn-Noranda, Québec. This initiative aims to extend five recent drill holes to explore a newly identified mineralized zone located beneath the established Berrigan mineralized zone. The exploration follows a press release from August 14, 2023, detailing a large land package under option from Chibougamau.
The boreholes are strategically designed to intersect the same horizon where previous drilling identified significant mineral intersections, notably drill hole TOM-25-015, which revealed impressive results, including 5.08% zinc equivalent over 98.50 meters, with notable sections like 23.20% zinc equivalent over 4.90 meters.
The Phase 1 drilling results highlighted valuable mineralization across various holes, with some postings showing substantial grades of zinc, gold, and silver. Key historical data from previous phases indicate high potential in the area, with meaningful grades that could substantially enrich Chibougamau’s resource profile.
TomaGold's ongoing 1,500-meter Phase 2 drilling program aims to test the newly recognized Berrigan Deep Zone further, which could potentially unlock additional resources. The drilling is guided by industry standards, with calculations based on established metallurgical recovery factors.
The project continues to attract attention as Chibougamau Independent Mines seeks to maximize its asset potential. With expert management and a compliant focus on exploration, the company is positioning itself for future developments within the mineral-rich region. For further details, shareholders can refer to TomaGold’s official communications and subsequent press releases, which promise to keep the market informed.
MWN-AI** Analysis
As of March 31, 2026, TomaGold Corporation has initiated an exciting drill program to extend five recently drilled holes targeting the newly discovered zinc/gold/silver zone beneath the established Berrigan mineralized zone. This development is particularly significant for Chibougamau Independent Mines, which holds the option on the Berrigan property. Notably, drill hole TOM-25-015 reported impressive mineralized intersections, including 5.08% Zn Eq over 98.50 meters, with potential highlights of 23.20% Zn Eq over 4.90 meters, emphasizing robust mineralization in the region.
For investors, this presents a compelling opportunity in the resource sector, particularly given the increasing global demand for zinc, gold, and silver. As the drill program progresses, focusing on the new Berrigan Deep Zone, investors should monitor closely the upcoming results. Successful drilling could spur significant interest in TomaGold and Chibougamau stocks, driving share prices upward.
Moreover, the technical parameters—calculating ZnEq and AuEq based on favorable market prices and metallurgical recovery factors—indicate a solid foundation for potential high returns. However, it is imperative to remain cognizant of inherent risks associated with exploration and mining ventures, including geological uncertainties, market volatility, and operational challenges.
Given the current phase of exploration drilling and the positive indicators already reported, investors are advised to consider a position in TomaGold and Chibougamau, particularly if early results from the ongoing drilling continue to demonstrate promising mineralization. As always, potential investors should conduct comprehensive due diligence, considering their risk tolerance and investment strategy before proceeding. Thus far, the Berrigan project appears to be budding with potential, and stakeholders might benefit from staying updated on its progress.

- 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.
