TomaGold Intercepts 6.68% ZnEq (1.57 g/t AuEq) over 48.05 Metres,

including 39.03% ZnEq (9.15 g/t AuEq) over 2.90 Metres at Berrigan

Mine and Identifies a Major Hydrothermal Footprint

Highlights

• Main High-Grade Intersections:

o Hole TOM-25-009 (from 156.70 m): 6.68% ZnEq (1.57 g/t AuEq) over 48.05 metres,

including 39.03% ZnEq (9.15 g/t AuEq) over 2.90 metres and 21.86% ZnEq (5.12 g/t

AuEq) over 5.40 metres.

o Hole TOM-25-009 (from 244.50 m): 5.44% ZnEq (1.27 g/t AuEq) over 15.20 metres,

including 25.15% ZnEq (5.85 g/t AuEq) over 2.55 metres.

o Hole TOM-25-010 (from 130.70 m): 2.67% ZnEq (0.62 g/t AuEq) over 48.30 metres,

including 12.87% ZnEq (3.00 g/t AuEq) over 6.25 metres.

• Assay results are pending for ﬁve drill holes targeting the lateral and depth

extensions of the known mineralized envelope (TOM-25-011 to TOM-25-015).

• Hydrothermal footprint: Identiﬁcation of a signiﬁcant hydrothermal signature at the

roof of the main mineralization, providing valuable exploration guidance for potential

extensions.

• Exploration ongoing: A Borehole EM survey is currently underway on the ground to

identify new targets.

Montreal, Québec, December 22, 2025 ‒ TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF)

(“TomaGold” or the “ Company”) is very pleased to announce the initial assay results from drill holes

TOM-25-009 and TOM-25-010 at its Berrigan Mine project located in the Chibougamau mining camp, in

Québec. These are the ﬁrst two of seven holes for a total of 3,098 metres at Berrigan Mine, with the

objective of testing the historical mineralized structure and opening new potential mineralization at depth.

The results conﬁrm the presence of high-grade gold-bearing polymetallic vein systems within an extensive

mineralized envelope hosted in ultramaﬁc rocks.

David Grondin, CEO of TomaGold, commented: “These initial results are truly outstanding, most notably

the 39% ZnEq intersection in hole TOM-25-009. The conﬁrmation of a hydrothermal footprint overlying the

main mineralized zones signiﬁcantly reinforces our geological understanding of the Berrigan Mine project.

With the EM survey currently underway and extension drilling results expected in January, we look forward

to deﬁning the full scale and continuity of the mineralized envelope.”

Jean Laﬂeur, P .Geo., VP Exploration at Toma Gold, add ed: “TomaGold is currently advancing an all -

encompassing litho -structural and geophysical compilation, synthesis and interpretation for its

Chibougamau mining c amp projects , incorporating AI modeling with Windfall Geotek’s proprietary

system. We've also completed additional geophysical work to reﬁne both gold and polymetallic targeting

for the upcoming winter 2026 exploration campaign. This approach has already yielded new targets, which

are currently being tested through diamond drilling. The latest drilling results at Berrigan Mine ocer a

glimpse into the exploration potential of some of these targets.”

Mineralization at Berrigan Mine is primarily associated with carbonatized ultramaﬁc rocks. Analysis of

visually non-mineralized samples, including intervals initially excluded from sampling, has identiﬁed low-

grade halos associated with quartz -carbonate stockwork that increase the potential volume of the

mineralized envelope. A borehole EM survey is currently being conducted on holes from this campaign to

guide future deep drilling. To ensure a comprehensive understanding of the system, the team proactively

analyzed previously unsampled sections to ensure that no low -grade mineralization or alteration halos

were overlooked.

Next steps will include receipt of assay results in January 2026 for ﬁve additional holes testing lateral and

depth extensions, integration of EM and complete core assay data into the resource model, compilation

and characterization of alteration systems, and planning of a ﬁeld exploration program. Phase 2 drilling

will be planned following compilation of Phase 1 drilling, geophysical data, and results from the upcoming

ﬁeld campaign.

Notes:

• The reported widths represent core lengths. ZnEq and AuEq are calculated using the Company’s standard

parameters. True width is estimated to be approximately 80–85% of the core length, depending on the deviation

angles.

• AuEq calculation was based on US$4150/oz Au, $51.36/oz Ag, US$5.044/lb Cu and $1.398/lb Zn. AuEq = Au g/t

+ (Ag g/t × 0.01237) + (Cu ppm × 0.000083) + (Zn ppm × 0.000023). The use of AuEq is to calculate cut-oY grades

for exploration purposes, and no adjustments were made for metal recovery.

• ZnEq calculation w as based on US$4047/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. The use of ZnEq is to calculate cut -oY

grades for exploration purposes, and no adjustments were made for metal recovery.

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 1,388,915 tonnes of material 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, in whole or in part, as a current mineral resource. Substantial data compilation, veriﬁcation,

and, potentially, additional drilling and resampling would be required by a qualiﬁed person before the

historical 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. For further information regarding the Berrigan Mine Project, please consult the press release dated

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 metal s 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

cutoc. The processed material is split and analyzed by ﬁre assay with ICP -OES ﬁnish to extinc tion. 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.
