Sankamap Announces Closing of Private Placement

Edmonton, Alberta--(Newsfile Corp. - October 6, 2025) - Sankamap Metals Inc. (CSE: SCU) ("Sankamap" or the "Company") is pleased to announce the closing of its Offering previously announced on July 23, 2025, with the sale of an aggregate of 21,755,772 units ("Units") at a price of $0.22 per Unit for total gross proceeds of $4,786,269 (the "Offering"). Each Unit will consist of one (1) common share (a "Share") and one-half (1/2) of a common share purchase warrant (a "Warrant"). Each whole Warrant will entitle the holder to purchase one (1) additional Share of Sankamap at an exercise price of $0.40 for a period of two years from the date or dates of closing of the Offering (a "Closing Date").

In connection with the sale of the Units, Sankamap paid a total of $168,933 in cash to arm's length finders (each, a "Finder"). Certain Finders elected to convert the cash portion of their finder's fees into Units of the Company, resulting in the issuance of an additional 256,922 Units. The Company also issued a total of 767,878 share purchase warrants to eligible Finders, on the same terms as the Warrants.

The net proceeds from the sale of the Units will be utilized to fund exploration and development of Sankamap's projects, and for general working capital. The Offering is subject to no objection from the Canadian Securities Exchange ("CSE") and any finder's fees payable will be issued in accordance with the policies of the CSE and applicable securities laws. All securities issued are subject to a four-month and one day hold period expiring on February 4, 2026.

Three (3) insiders of Sankamap participated in the Offering and such subscriptions are a related party transaction for the purposes of Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"), but Sankamap is relying on exemptions from the formal valuation and minority shareholder approval requirements provided under sections 5.5(a) and 5.7(1)(a) of MI 61-101 on the basis that the fair market value of the subscriptions, insofar as it involves the insiders of Sankamap, does not exceed 25% of the market capitalization of the Issuer, as determined in accordance with MI 61-101.

About Sankamap Metals Inc.

Sankamap Metals Inc. (CSE: SCU) is a Canadian mineral exploration company dedicated to the discovery and development of high-grade copper and gold deposits through its flagship Oceania Project, located in the South Pacific. The Company's fully permitted assets are strategically positioned in the Solomon Islands, along a prolific geological trend that hosts major copper-gold deposits; including Newcrest's Lihir Mine, with a resource of 71.9 million ounces of gold¹ (310 Mt containing 23 Moz Au at 2.3 g/t P+P, 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing 5 Moz Au at 1.9 g/t measured, 61 Mt containing 4.9 Moz Au at 2.3 g/t Inferred).

Exploration is actively advancing at both the Kuma and Fauro properties, part of Sankamap's Oceania Project in the Solomon Islands. Historical work has already highlighted the mineral potential of both sites, which lie along a highly prospective copper and gold-bearing trend, suggesting the possibility of further, yet-to-be-discovered deposits.

At Kuma, the property is believed to host an underexplored and largely untested porphyry copper-gold (Cu-Au) system. Historical rock chip sampling has returned consistently elevated gold values above 0.5 g/t Au, including a standout sample assaying 11.7% Cu and 13.5 g/t Au²; underscoring the area's significant potential.

At Fauro, particularly at the Meriguna Target, historical trenching has returned highly encouraging results, including 8.0 meters at 27.95 g/t Au and 14.0 meters at 8.94 g/t Au³. Complementing these results are exceptional grab sample assays, including historical values of up to 173 g/t Au³, along with recent sampling by Sankamap at the Kiovakase Target, which returned numerous high-grade copper values, reaching up to 4.09% Cu. In addition, limited historical shallow drilling intersected 35.0 meters at 2.08 g/t Au³, further underscoring the property's strong mineral potential and the merit for continued exploration. With a commitment to systematic exploration and a team of experienced professionals, Sankamap aims to unlock the untapped potential of underexplored regions and create substantial value for its shareholders.
