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

International Metals Mining Corp. has entered into an arm's-length securities exchange agreement dated Aug. 7, 2025, with 1367881 B.C. Ltd. (Privco), a British Columbia incorporated company that holds the rights to acquire 100-per-cent right, title and interest in the Bell Lake VMS (volcanogenic massive sulphide) property, located in Northwestern Ontario.

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, International Metals Mining will issue 10 million common shares to Privco shareholders at a deemed price of six cents per share to acquire all outstanding shares of Privco. Privco's sole asset is an option to acquire 100 per cent of the property for cash payments over two years equalling $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 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 19.8 million tonnes at 8.50 per cent zinc, 1.06 per cent copper, 0.91 per cent lead and 119.7 grams per tonne silver.
• Pervasive glacial till cover and historically a preponderance of shallow drill holes testing of near-surface geophysical conductors have left the downdip potential wide open for discovery.

The property consists of 30 non-contiguous mining claims totalling 69 cells covering an area of 1,931 hectares and is located in the Sturgeon Lake mining camp approximately 270 kilometres northwest of Thunder Bay, Ont. The property lies 3.5 kilometres 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. 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 subprovince of the Superior province. Mineralization is hosted within the South Sturgeon Lake assemblage, a nine-kilometre-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-kilometre-diameter, 2,735-million-year-old submarine Sturgeon Lake caldera.

The orebodies are conformable, strata-bound, 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 two kilometres of the prospective rocks that host the Sturgeon Lake mine deposits. Historical drilling on the Bell Lake property in the early 1970s encountered mineralization up to 2.62 per cent copper and 1.9 grams per tonne gold over 4.3 metres at the Claw Lake occurrence. Just 300 metres 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 per cent copper, 0.19 per cent zinc and 27.2 grams per tonne silver over 0.45 metre.

Public files indicate that the property has been tested with 91 diamond drill holes. Of that, a total 66 holes tested the fertile mine horizon rocks. Most of the diamond drill holes reached depths of 200 metres or less, averaging 32 metres, with only one hole reaching a vertical test depth of 600 metres over the two-kilometre strike of the favourable 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-metre depth limit, followed by deep-penetrating geophysics, is recommended to locate any new sulphide lenses.
