TomaGold Set to Launch Strategic Drilling Campaign
on its Chibougamau Projects
Planned 53-hole exploration drilling campaign targeting mainly
the Berrigan, Radar, David, Dufault and Obalski properties
Montreal, Québec, June 20, 2025 ‒ TOMAGOLD CORPORATION (TSXV: LOT) (“TomaGold” or the
“Company”) is pleased to announce the upcoming launch of its 2025 drilling campaign, which will focus
primarily on the properties currently under option from SOQUEM and Chibougamau Independent Mines
in the Chibougamau Mining Camp, as well as its wholly-owned Obalski Project (the “Chibougamau
Projects”).
David Grondin, CEO of TomaGold stated: “The Chibougamau Mining Camp has recently attracted significant
exploration activity, underscoring the region’s increasing potential for gold and copper discoveries. Since
the beginning of the year, we have compiled project data, advanced preliminary work, identified high-
priority targets, and prepared our properties to be drill-ready. Our 53-hole exploration program will focus
on our key projects—Berrigan, Radar, David, Dufault, and Obalski—with the objective of uncovering new
gold-copper mineralization on well-defined, strategically selected targets. We are eager to commence
drilling and build on the momentum in this highly prospective region.”

Drill and Work Permits Secured
TomaGold has obtained all the necessary drilling and work permits, including the ATI (“Autorisation de
Travaux à Impact”) and forestry permits, to begin exploration activities across its Chibougamau Projects.
Drill Pad Setup and Mobilization Status
All access trails to the drill sites have been cleared and secured, and the drill setups are ready for immediate
mobilization. A total of 53 drill targets have been identified and are fully permitted. While preparing the
sites during the winter, the team also conducted limited and selective surface sampling in select areas.
Analytical results from this sampling are currently pending.
Geophysical Survey Work on Obalski
A downhole resistivity/induced polarization (IP) logging survey was conducted in hole OBS-17-002, which
intersected the newly interpreted NE-SW Zone on the Obalski Project. The objective was to determine the
in-situ physical properties of this high-grade copper-gold zone to define the most effective geophysical
method for the upcoming drilling campaign. The resistivity and chargeability contrasts measured between
the host rocks and the NE-SW Zone are up to 10,000 times more conductive and 10 times more chargeable,
respectively. To confirm these results, the geophysical properties of hole OBS-23-032 were also measured.
This hole was interpreted to have intersected the same NE-SW Zone some 65 m further south. The results
again confirmed similar conductive and chargeable contrasts of 25,000x and 10x, respectively. These very
high contrasts suggest that electromagnetic (EM) and induced polarization (IP) methods could be
successfully applied in this geological context of the Obalski project and possibly the Chibougamau Camp.
3D Modelling and Structural Reinterpretation
TomaGold has completed approximately 95% of the geological reinterpretation and 3D modeling of the
Obalski project. The updated model incorporates historical and recent data, providing a more
comprehensive understanding of structural controls and mineralization trends . Final conclusions and
visuals from the model will be presented shortly.
The Company has initiated a similar modelling and reinterpretation process across its other projects,
leveraging the structural insights gained from the Obalski project reinterpretation.
Upcoming Geophysical Surveys (Pending Crew Availability)
TomaGold has outlined a series of geophysical surveys to be conducted across its Chibougamau Projects in
2025, pending crew availability and seasonal access. These surveys are designed to refine drill targeting
and enhance geological modelling across key assets.
Summary of Planned Geophysical Work by Project:
Project Planned Geophysical Survey
Obalski
(100% TomaGold)
IP survey along the D vein, covering the Wilson and South
zones
Radar
(Under option from SOQUEM)
Airborne magnetic survey (50 m line spacing), ground IP
surveys on new targets, possible 3D ambient tomography
David
(Under option from SOQUEM)
Downhole IP in historical and recent drill holes, pending
casing verification
Dufault
(Under option from SOQUEM)
NW–SE IP survey over the 055° vein corridor; NE–SW IP over
the Bourbeau Sill outlet zone
Berrigan
(Under option from Chibougamau Independent Mines)
2D and 3D modelling under way; geophysical surveys
anticipated in subsequent phases
These surveys will complement the current structural reinterpretation work and support future drilling
campaigns across the portfolio.
