Argo Increases Its Uranium Mineral Claim

Position in the Athabasca Basin,

Saskatchewan

Toronto, Ontario--(Newsfile Corp. - November 3, 2025) - Argo Gold Inc.

(CSE: ARQ) (OTC Pink:

ARBTF) (XFRA: A2ASDS) (XSTU: A2ASDS) (XBER: A2ASDS)

("

Argo

" or the "

Company

") has

increased its uranium mineral claim position at

Thunderclap

in the Athabasca Basin, Saskatchewan.

Argo Gold's 100% interest at

Thunderclap

now covers 264 hectares of prospective uranium mineral

claims in the Athabasca Basin.

Argo Gold also has a 100% interest in three other uranium areas in the

Athabasca Basin -

Parker Lake

,

Thunderbolt

and

ZigZag -

which altogether total 15,962 hectares and

are considered prospective for uranium mineralization.

Thunderclap

is located 16 kilometres SSW of the McLean Lake Uranium Mine and Mill, 18 kilometres

SW of the Rabbit Lake Mine and Mill, 30 kilometres NE of Cameco's Cigar Lake High Grade Uranium

Mine, 12 kilometres south of the Points North Landing camp and airstrip, and 17 kilometres south of

Denison Mine's Midwest Lake ISR uranium deposit.

Thunderclap is surrounded by Cameco

Corporation, with Uranium Energy Corp (UEC) to the immediate east.

To the east of the

Thunderclap

mineral claim, drilling by Asamera in 1982 returned 0.13% eU

3

O

8

over

4 metres in sheared, reduced yellow brown to olive green chlorite schist from the diamond drillhole

Q12a-9.

The unconformity lies at a depth of 182 metres with bleaching, hematite and chlorite alteration in

basement rocks.

(Reference: SMDI 1969 located 600 metres east of

Thunderclap

).

A second drill hole

(SHA-042) intersected the unconformity at 197.2 metres returning 0.021% U3O8/4.0 m from 306-310 m

and 0.071% U3O8/7.0 m from 499-506 m at the contacts of semipelitic gneisses and pegmatites.

(Reference: SDMI 3480 is located 1500 metres east of

Thunderclap

).

To the NW of

Thunderclap

and 5.28 kilometres south of the Midwest Lake Uranium Deposit, historical

drilling intersected 0.25% eU

O

over 4.0 metres in DDH Q8-24 from 166.3 to 170.3 metres in the lower

sandstone and regolith in black pyritic sandstone and 1.1 metres in the lower sandstone of 14.8% Ni,

7.2% Co, 1.44% Cu, 1.14% As and 0.16% Pb.

(Reference: SMDI 2551).

Historic drilling 3.5 kilometres

to the SW of

Thunderclap

returned 0.34% U

3

O

8

over 0.5 metres as well as anomalous nickel arsenide,

cobalt, copper, lead and zinc.

(Reference: SMDI 2751).

The anomalous polymetallic mineralization is

considered to be very significant, as the Cigar Lake high grade uranium mine carries similar polymetallic

mineralization along with the uranium and gold/silver.

The Thunderclap Property is considered highly

prospective and has never been drilled-tested.

The Fraser Institute's Annual Survey of Mining Companies ranked Saskatchewan as third in the world for

mineral exploration and mining investment attractiveness.

Argo is well positioned to advance mineral

exploration with high-quality assets in a mining friendly jurisdiction.

National Instrument 43-101 Disclosure

The technical information in this news release has been reviewed and approved by Michael Guo, who is

a "Qualified Person" as defined in National Instrument 43-101. Historical geochemical, drilling results

and geological descriptions quoted in this news release were taken directly from news releases by other

mineral explorers and from information provided by the Government of Saskatchewan. Management

cautions that results reported by other parties on adjacent properties have not been verified nor

confirmed by its Qualified Person, but Argo believes they create a scientific foundation for the

exploration in the district. Management further cautions that historical results or discoveries on adjacent

or nearby mineral properties are not necessarily indicative of the results that may be achieved on Argo's

mineral properties.

Note on U

Equivalence

Some of the reported U

, which is determined

through downhole probing techniques. These methods estimate the uranium content in situ by measuring

gamma radiation, which is then converted into an eU

value based on standard calibration factors. It's

important to note that this is an indirect measurement, and the actual uranium species may vary. The

eU

values provide an estimate of uranium concentrations in the mineralization, but further assaying

and metallurgical testing would be needed to confirm the precise uranium species and chemical grade.
