TomaGold Confirms Lateral Continuity of the Berrigan Deep Zone Over

More Than 250 Metres with Extension Hole TOM-25-009EXT

Highlights

• Significant mineralized intersections: Drill hole TOM-25-009EXT intersected multiple zinc, gold,

silver and copper-rich mineralized intervals at depths between 389.35 m and 530.35 m, including:

• 29.90 m grading 2.24% ZnEq (0.52 g/t AuEq) from 469.25 m to 499.15 m, including 1.75 m at

8.03% ZnEq, 2.60 m at 7.32% ZnEq, and 1.55 m at 6.45% ZnEq.

• 13.75 m grading 1.83% ZnEq (0.43 g/t AuEq) from 395.20 m to 408.95 m, including 1.00 m at

6.18% ZnEq.

• 4.35 m grading 2.46% ZnEq (0.58 g/t AuEq) from 526.00 m to 530.35 m, including 0.90 m at

8.87% ZnEq.

• Lateral continuity confirmed over more than 250 metres: Drill hole TOM-25-009EXT fills a strategic

gap between discovery hole TOM-25-015 (5.08% ZnEq over 98.50 m) and the recently reported TOM-

25-011EXT (2.05% ZnEq over 204.25 m), confirming the lateral continuity of the Berrigan Deep zone

over more than 250 metres.

• Results pending for holes TOM-25-010EXT, TOM-25-012EXT and TOM-25-013EXT: Mineralization has

been consistently observed in the drill core recovered from all three other extension holes, with assay

results still pending.

• Geophysical model validation: The extension of drill hole TOM-25-009 (TOM-25-009EXT), extended to

a final depth of 621 m, successfully intersected the upper portion of the modeled conductive plate.

These results confirm the three-dimensional accuracy of the geological model. Preliminary 3D model

Montréal, Québec, July 16, 2026 ‒ TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF)

(“TomaGold” or the “Company”) announces assay results from the extension of drill hole TOM-25-009

(TOM-25-009EXT), completed as part of Phase 2 of its drilling program at the Berrigan Mine Project, located

in the Chibougamau Mining Camp, Québec (see Figure 1).

This drill hole was speciﬁcally designed to test the upper portion of the conductive plate modeled at depth.

Originally terminated at 276 m during Phase 1, the hole was extended by an additional 345 m to a ﬁnal

depth of 621 m. It intersected a lithological sequence dominated by altered pyroxenites and peridotites,

conﬁrming the presence of a signiﬁcant polymetallic hydrothermal system.

David Grondin, President and CEO of TomaGold, said: "The results from extension hole TOM-25-009EXT

fully validate our geophysical model. Following the initial discovery in drill hole TOM -25-015 and the

extensive 204-metre mineralized envelope recently reported in drill hole TOM-25-011EXT, this latest hole

demonstrates that the upper portion of the conductive plate is also strongly mineralized. These results

conﬁrm the excellent vertical and lateral continuity of the Berrigan Deep zone, which now extends over

more than 250 metres in length. The consistent presence of robust grades further strengthens our

conﬁdence in the continuity of this structure at depth and in the large-scale growth potential of the Berrigan

Project. "

The Company is also encouraged by the consistent mineralization observed in the drill core recovered from

the three remaining extension holes: TOM-25-010EXT, TOM-25-012EXT and TOM-25-013EXT, for which

assay results are still pending.

Geological Context and District-Scale Potential

The data from the extension of drill hole TOM-25-009 further support the model of a large hydrothermal

system extending at depth.

• Host lithologies: The mineralized intersection cuts an ultramaﬁc to maﬁc sequence consisting of

alternating pyroxenites and peridotites, lithologies that have proven to be excellent hosts for

mineralization at Berrigan.

• Mineralization signature: From 389.35 m to 530.35 m, the mineralization is characterized by

lenses and clusters of sulphides (locally reaching up to 50%, dominated by pyrrhotite and

sphalerite, with chalcopyrite also present). Notably, these sulphides are closely associated with an

intense system of blue quartz and carbonate veins and veinlets, indicating high -temperature

hydrothermal ﬂuid circulation.

• Structural controls and alteration: Mineralization is preferentially concentrated within sheared

and brecciated zones that served as conduits for hydrothermal ﬂuids. This strong structural

permeability is accompanied by intense and pervasive alteration (carbonatization, chloritization

and talc alteration), demonstrating the persistence and intensity of the Berrigan Deep hydrothermal

system.

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$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.

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 suficient 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

cutof. 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.

The technical content of this press release has been reviewed by Jean Laﬂeur, P .Geo., Vice President of

Exploration of the Company, and Suzie Tremblay, P .Geo., Vice President of Operations at Explo-Logik Inc.

and a consultant to TomaGold, each of whom is a Qualiﬁed Person as deﬁned under National Instrument

43-101. Mr. Laﬂeur has approved the technical content of this press release.
