TomaGold Borehole EM Survey Confirms Berrigan Deep Zone
Survey also validates significant mineralization and unlocks new targets
Highlights
• Direct correlation with mineralization: The modeled geophysical plates explain the
presence of semi-massive to massive sulfides intersected in holes TOM-25-009 to
TOM-25-015.
• Priority target BER-14C: Identification of a major 160 x 300 m plate, open at depth and
to the northeast, suggesting the presence of a significant massive sulfide lens near drill
hole TOM-25-014.
• Confirmation of Berrigan Deep: The TOM-25-015 drill hole perfectly intersects the
southeast extension of the BER-14C plate, validating the continuity of the mineralized
system at a depth of over 450 metres.
Montreal, Québec, February 5, 2026 ‒ TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF)
(“TomaGold” or the “Company”) is pleased to announce the interpretation results of the borehole
electromagnetic (BHEM) survey completed on its Berrigan Mine project, located in the Chibougamau
mining camp.
The survey, conducted by Abitibi Geophysics, modeled ten conductive plates of varying orientation and
size that not only corroborate the high -grade intersections already announced, but also indicate
significant extension potential, particularly with the discovery of the Berrigan Deep zone.
David Grondin, President and CEO of TomaGold, stated: “The geophysics confirm what our drill cores
indicated: Berrigan Mine sits on a large-scale mineralized system. The BER-14C plate, in particular, extends
the mineralization signature of holes TOM-25-014 and TOM-25-015 with a vector pointing to an even more
conductive zone to the northeast.”
Technical analysis of the plates
The survey uses Terrascope PRO5U transmitters (up to 15 kW) powered by a Wildcat generator to transmit
a bipolar signal in a 530 x 560 m surface loop with a current of 30 A. The borehole measurements are taken
at frequencies of 5 Hz and 1 Hz using a GPS-synchronized DigiAtlantis triaxial probe, which captures the
components of the magnetic field. Finally, the data is processed and modeled using specialized Maxwell
and Oasis Montaj software, with the conductive plates shown in green in Figure 1.

Note: TomaGold has reverted to reporting elemental assay results rather than metal equivalent grades. The
mineralization style encountered at Berrigan Mine di=ers from typical sulphide deposits in the surrounding
area, including Scott Lake, Lemoine and Mattagami, as well as outside the immediate region such as
Normétal, Rouyn-Noranda and Timmins. As a result, metallurgical recovery assumptions remain uncertain
at this stage and cannot currently support the use of metal equivalent calculations.
Next Steps
TomaGold plans to:
1. Drill three new holes (TOM-26-016 to TOM-26-018) to test the northeast and depth extensions of
the BER-14C conductive plate.
2. Conduct additional follow-up drilling to extend holes TOM-25-010, 011, and 013 with the goal of
reaching modeled targets, and drill a corner hole from hole TOM-25-015.
3. Conduct a low-frequency surface electromagnetic (EM) survey to better define the thickness,
continuity, and lateral extent of the mineralized system.
About the Berrigan Mine Project
The Berrigan Mine property consists of 16 claims totalling 483 hectares located 4 km north-northwest of
the town of Chibougamau. TomaGold has an option to acquire 100% of the property from Chibougamau
Independent Mines Inc.
The property has been the subject of more than one historical estimate. Met-Chem Canada Inc. prepared
the most recent of these in April 2001 in a report titled: “Pre-feasibility study: Etude Conceptuelle, Projects
Berrigan and Tortigny” by Chuinard et al. In the report, a resource estimate completed using polygonal
estimation techniques stated 1.39 Mt grading 3.17% Zn and 1.77 g/t Au on the main Berrigan Mine zone.
No resource classifications were given for the resource (GM61359).
The mineral resource estimate presented above is historical in nature and was not prepared in accordance
with National Instrument 43-101 standards. Accordingly, the reader is cautioned not to rely on this
estimate, as the Company is not treating the estimate as a current mineral resource. The qualified person
has not done sudicient work to make the resource current. Substantial data compilation, verification, and,
potentially, additional drilling and resampling would be required by a qualified person before the historical
4
estimate could be classified as a current mineral resource. There can be no assurance that any portion of
the historical mineral resource will ultimately be confirmed or demonstrated to be economically viable.

September 13, 2023.
Technical Disclosure
The drilling program was managed by Explo-Logik of Val-d’Or, Québec. Drill core was split in half, with one
half submitted to AGAT Laboratories at Val-d’Or for analysis. Gold was analyzed by fire assay (50 g) with
atomic absorption finish, while base metals were analyzed by four-acid digestion with ICP-OES finish.
Samples with gold grades greater than 10 g/t are reprocessed using metallic screening with a 106 µm
cutod. The processed material is split and analyzed by fire assay with ICP -OES finish to extinction. A
separate split is prepared to independently analyze mineralized intervals with a target grade greater than
1.00% Cu-Zn using a Na₂O₂ fusion with ICP-OES or ICP-MS finish. Sample preparation duplicates, certified
reference standards, and blanks are inserted into the sample stream.

President of Exploration of the Company, and Suzie Tremblay, P .Geo., Vice President of Operations at
Explo-Logik Inc. and a consultant to TomaGold, eac h acting as a Qualified Person under National
Instrument 43-101.
