Each Finder’s Warrant entitles the holder to purchase one (1) common share of Sankamap at an exercise price of $0.35 for a period of twenty-four (24) months from the date of issuance.

The gross proceeds from the sale of the Units will be used to advance exploration and development of Sankamap’s projects, including the acquisition of a drilling rig to be installed at the Fauro property, which will enable the simultaneous drilling of both the Kuma and Fauro properties, as well as for general working capital purposes. 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 July 19, 2026.

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 Newmont’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 Au³, 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 Au⁴. Complementing these results are exceptional grab sample assays, including historical values of up to 173 g/t Au⁴, 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 Au⁴, 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.
