INTERNATIONAL METALS MINING CORP.

INTERNATIONAL METALS MINING SIGNS AGREEMENT TO ACQUIRE A 100% INTEREST IN THE BELL LAKE VMS PROPERTY IN NORTHWEST ONTARIO

Vancouver, British Columbia (August 12, 2025) - International Metals Mining Corp. (the "Company") (TSXV: IMM) (OTC PINK: CYNXF) (FSE: C2Y) is pleased to announce that it has entered into an arms-length Securities Exchange Agreement dated August 7, 2025 with 1367881 B.C. Ltd. ("Privco"), a British Columbia Incorporated company that holds the rights to acquire 100% right, title, and interest in the Bell Lake VMS Property (the "Property"), located in northwestern Ontario (the "Acquisition")'.

The Securities Exchange Agreement provides for the purchase of all the securities of Privco that are owned or held by the Privco shareholders at the time of closing. At closing IMM will issue ten million common shares to Privco shareholders at a deemed price of $0.06 per share to acquire all outstanding shares of Privco. Privco's sole asset is an option to acquire 100% of the Property for cash payments over two years equaling $60,000 and the issue by the Company of shares equal in value to $40,000.

Closing is subject to due diligence, exchange approval and other customary closing conditions.

Highlights of the Bell Lake VMS Property

Bell Lake VMS Property lies immediately southeast and adjacent to First Quantum's past-producing Sturgeon Lake Mine and is host to the highly prospective continuation of the volcanogenic massive sulphide ("VMS") producing volcanic stratigraphy.

The Sturgeon Lake VMS mining camp is host to five high-grade past producing zinc - copper - lead - silver - gold mines having a total combined production of 19.8Mt @ 8.50% Zn, 1.06% Cu, 0.91% Pb and 119.7g/t Ag.

Pervasive glacial till cover and historically a preponderance of shallow drill holes testing of near surface geophysical conductors has left the down dip potential wide open for discovery.

The Property consists of 30 noncontiguous mining claims totaling 69 cells covering an area of 1,931 hectares (Figure 1) and is located in the Sturgeon Lake mining camp approximately 270 kilometers northwest of Thunder Bay, Ontario. The Property lies 3.5 kilometers east of the past producing Sturgeon Lake Mine, now under rehabilitation, operated by Falconbridge Mines between 1974 and 1981. The Sturgeon Lake Mine is now owned by Glencore Canada Corp ("Glencore"). Current activities by Glencore involve the operation of a water treatment plant so the Sturgeon Lake Mine road remains accessible along with an operating electrical infrastructure.

Past producing deposits in close proximity to the Property all occur within the Sturgeon Lake greenstone belt in the Wabigoon Sub-province of the Superior Province. Mineralization is hosted within the South Sturgeon Lake assemblage, a 9 km thick, dominantly bimodal package of basalt-rhyolite volcanic rocks divided into three depositional cycles by Morton et al. (1990) related to the formation of a 30 km diameter, 2735 Ma submarine Sturgeon Lake caldera.

The orebodies are conformable, stratabound, zoned accumulation of massive to semi-massive sulphides in a volcanic or volcaniclastic host separated by cherty tuffaceous rhyolite units. The ore is zoned, with a footwall stringer zone, lower chalcopyrite-sphalerite interval, in turn overlain by banded pyrite-sphalerite ore in each zone. The mineralogy of the ore includes pyrite, sphalerite, chalcopyrite, galena, tetrahedrite-tennantite, arsenopyrite and minor pyrrhotite (Franklin et al., 1975).

The Property is located along the eastern margin of the caldera sequence of rocks and is host to over 2 km of the prospective rocks that host the Sturgeon Lake Mine deposits. Historical drilling on the Bell Lake Property in the early 1970's encountered mineralization up to 2.62% Cu and 1.9 g/t Au over 4.3 m at the Claw Lake Occurrence. Just 300 meters northwest of the Property (and striking onto the Property) the Swamp Lake SE Occurrence was drilled by Matagami Lake Mines Ltd in 1974 intersecting 2.72% Cu, 0.19% Zn and 27.2 g/t Ag over 0.45 m.

Public files indicate that the Property has been tested with 91 diamond drills holes. Of that, a total 66 holes tested the fertile mine horizon rocks. Most of the diamond drill holes reached depths of 200 meters or less averaging 32 meters with only one hole reaching a vertical test depth of 600 m over the 2 kilometer strike of the favorable South Sturgeon Lake assemblage.

Historical work has outlined and partially tested the horizon that hosts the sulphide deposits in the near surface environment. Significant massive sulphide deposits may still be present at depth. Their location is influenced by the presence of pre-existing faults related to the formation of the caldera.

The geological database for the property requires an in-depth compilation and field checking as detailed studies in the past focused on the known deposits leaving the geological story less understood outside of the immediate mine footprint. Diamond drill testing beneath the historical 200 meter depth limit followed by deep penetrating geophysics are recommended to locate any new sulphide lenses.
