• Drill hole TOM-25-015 conﬁrms the discovery of a new major semi-massive sulﬁde

zone, named Berrigan Deep, which remains open at depth

• Results pending for the last three drill holes (TOM-25-011 to TOM-25-013) and for the

borehole geophysical electromagnetic (EM) survey

Montreal, Québec, January 29, 2026 ‒ TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF)

(“TomaGold” or the “Company”) is pleased to announce the assay results from drill holes TOM-25-014

and TOM-25-015 on its Berrigan Mine project, located in the Chibougamau mining camp. Hole TOM-25-

015 intersected signiﬁcant semi-massive mineralization at depth, opening up a new extensi on zone

named Berrigan Deep.

David Grondin, CEO of TomaGold, commented: “Drill hole TOM-25-015, grading 5.75% ZnEq (1.34 g/t

AuEq) over 98.5 m, is truly transforming the Berrigan Mine project and highlights a new semi-massive

sulﬁde zone that extends at depth beneath the known zones. This very encouraging result suggests the

presence of a large mineralized system that remains open at depth.”

Jean Laﬂeur, P .Geo., VP Exploration at TomaGold, added: “The concept of a new deep mineralized zone is

not new in Abitibi, where mineralization has been documented at depths of over 1,000 to 2,000 metres.

The Cadillac camp is the best example of this along the Larder Lake –Cadillac fault, with the Doyon,

Bousquet 1 and 2, and LaRonde series of deposits extending from the surface to depths of over 3 km.

However, this approach remains new for the Chibougamau mining camp. The 2D and 3D modeling

currently underway will enable TomaGold to target the -250 to -500 metre interval in the northern portion

of the camp, particularly in the Berrigan sector. Surface and borehole electromagnetic surveys will provide

3D vectors to better deﬁne the distribution of sulphide-rich mineralization. We believe that this second

zone, called “Berrigan Deep”, could be linked to historical intersections located up to 1 km east of the

main Berrigan Mine zone, near more felsic lithologies , such as tu^s and porphyries. Field work,

geophysical surveys, and drilling planned for 2026 will be critical in assessing its extension in all

directions.”

TomaGold will launch a new drilling program at Berrigan Mine as soon as it receives the results of the last

three drill holes (TOM-25-011, 012, and 013) and the borehole geophysical electromagnetic (EM) survey,

which are expected in early February. This program will focus primarily on following up and extending this

exciting discovery.

Drill Hole TOM-25-015: A Major Discovery at Depth

Figure 1: Drill hole TOM-25-015, a major discovery at depth

Drill hole TOM-25-015 was drilled at a steeper angle to test the root of the Berrigan mineralized system. It

revealed a wide, high-grade zone of mineralization at a depth of over 450 metres within a serpentinized

peridotite unit.

• Mineralogy and textures: The Berrigan Deep zone (from 451.20 to 549.70 m) is characterized by a

high proportion of semi-massive to massive sulﬁdes in centimetric and metric horizons or veins.

The intervals are particularly rich in sphalerite and pyrrhotite, with chalcopyrite and galena, and

minor amounts of arsenopyrite and possibly scheelite (inferred from the tungsten content).

These sulﬁdes also occur as coarse clusters and breccia ﬁllings.

• Structural control: Mineralization is closely associated with a zone of shearing and fracturing.

Alteration is marked by a strong presence of talc, chlorite, and dolomite, suggesting prolonged

hydrothermal circulation.

• Extension potential: The presence of another mineralized interval lower in the hole (between

583.75 and 586.70 m), characterized by a contact breccia and fault mud, indicates that the

hydrothermal system remains open and active at depth.

Drill Hole TOM-25-014: Extension of the Vein System

Drill hole TOM-25-014 further deﬁned the mineralized vein system, which extends westward at various

depths.

• Vein network: Technical descriptions identify two distinct events:

1. A network of quartz-carbonate veins with coarse magnetite margins, indicating a high-

temperature phase.

2. A network of undulating sheared veins, much richer in sulﬁdes (sphalerite, pyrrhotite,

galena, and traces of chalcopyrite).

• Key intersections: The interval between 185.00 and 187.10 m (2.10 m at 28.69% ZnEq) is located

at a brecciated lithological interface. Mineralization here is of the “stringer” and cluster type.

• Lithological context: The hole intersected alternating serpentinized peridotite and pyroxenite

(tremolite), the latter often acting as barriers or conduits for mineralizing ﬂuids. Pyroxenites and

gabbros were preferentially altered.

Notes:

• 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$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-o^ grades

for exploration purposes, and no adjustments were made for metal recovery. The Company is currently in the

initial exploration phase, following historical drilling. At this stage, the Company does not have any metallurgical

data and no comparative studies have been conducted, given the geological complexity of the ultramaﬁc host

rock. Furthermore, the Company is not aware of any deposits that may have similar geological characteristics.

• ZnEq calculation was 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-o^

grades for exploration purposes, and no adjustments were made for metal recovery. The Company is currently

in the initial exploration phase, following historical drilling. At this stage, the Company does not have any

metallurgical data and no comparative studies have been conducted, given the geological complexity of the

ultramaﬁc host rock. Furthermore, the Company is not aware of any deposits that may have similar geological

characteristics.

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, as the Company is not treating the estimate as a current mineral resource. The qualiﬁed person

has not done su^icient 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

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 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

cuto^. 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.
