Sankamap Updates Status on Late Filing of Financial Statements; Extends MCTO

Edmonton, Alberta--(Newsfile Corp. - December 3, 2025) - Sankamap Metals Inc. ("Sankamap" or the "Company") further to the Company's news releases dated October 21, 2025, November 4, 2025, and November 18, 2025, the Company continues to work towards the filing of its annual audited financial statements and management's discussion and analysis for the fiscal year ended June 30, 2025 (the "Required Filings"). The Company has obtained approval from the Alberta Securities Commission to extend the Management Cease Trade Order ("MCTO") under National Policy 12-203 Management Cease Trade Orders ("NP 12-203") until December 28, 2025.

While the audit of Sankamap's private subsidiary has now been completed, timing adjustments in the subsidiary's audit resulted in a brief postponement of fieldwork and the review of Sankamap's audit file. The upcoming holiday period is also expected to affect scheduling. To support timely completion of the audit, the Company intends to appoint the subsidiary's auditor as its auditor, as their familiarity with the Company's mineral property and the Solomon Islands jurisdiction is expected to facilitate an expedited process. A change of auditor is underway, and the Company expects to file the required change of auditor documentation shortly.

The Required Filings were due to be filed by October 28, 2025. In connection with the anticipated delays in making the Required Filings, the Company made an application for a Management Cease Trade Order ("MCTO") under National Policy 12-203 Management Cease Trade Orders ("NP 12-203") to the Alberta Securities Commission, as principal regulator for the Company, and the MCTO was issued on October 29, 2025. The MCTO restricts all trading by the Company's CEO and CFO in securities of the Company, whether direct or indirect. The issuance of the MCTO will not affect the ability of persons who are not directors, officers or insiders of the Company to trade their securities. The MCTO will remain in effect until the Required Filings are filed or until it is revoked or varied.

The Company expects to proceed with the filing of its interim first-quarter financial statements shortly after the Required Filings have been completed and submitted.

The Company confirms that it intends to satisfy the provisions of the alternative information guidelines described in NP 12-203 by issuing bi-weekly default status reports in the form of a news release until it meets the Required Filings requirement. The Company has not taken any steps towards any insolvency proceeding and the Company has no material information relating to its affairs that has not been generally disclosed.

About Sankamap Metals Inc.

Sankamap Metals Inc. 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.
