Los Andes Copper Ltd. (TSXV: LA,OTC:LSANF) (OTCQX: LSANF) (‘Los Andes’ or the ‘Company’) is pleased to provide an update on the Company’s successful community engagement and social development programs carried out during 2025.

Highlights

• Successful launch of third Female Entrepreneurs program, receiving 350 applications.
• Renewal of the partnership with national and local educational institutions to develop mining-related skills at local high schools and universities.
• Two community agreements renewed to advance work on outdoor recreation projects and conceptual environmental offset studies for the Vizcachitas Project.
• Organized landmark seminar facilitating important discussions on the compatibility and complementary nature of mining and farming activities in the Valparaíso Region.

Santiago Montt, CEO of Los Andes, commented:

‘We have made further notable achievements this year with our community outreach programs which remain a vital part of our work to advance the project. The successful completion of our programs across the year has helped to strengthen partnerships across the local communities.

‘We are very pleased with the response and look forward to continuing to work closely with the community to highlight the benefits Vizcachitas will bring. This includes outdoor recreation projects and the conceptual development of environmental offset that could benefit community properties which have remained underused.

‘We remain committed to creating shared values and fostering sustainable development in the Putaendo County, San Felipe Province and Valparaíso Region through our partnerships, programs and collaboration with stakeholders. We look forward to continuing this important work in the years ahead.’

Further information

Securing and maintaining the social license to operate and enhancing community engagement is a key focus for Los Andes. Work on the ground has continued with the Company’s community engagement teams focusing on ensuring that the Vizcachitas project remains an engine of sustainable regional development and that meaningful collaboration is occurring with the local stakeholders.

The Vizcachitas project is expected to provide sustainable economic development to the Valparaíso Region. The regional GDP is expected to increase by more than 3% with the project’s development, according to the social impact assessment study carried out by José Ignacio Guzmán, Professor at Universidad Católica de Chile (2023).

The Company successfully launched the third iteration of its Female Entrepreneurs program. The number of applications increased by 10% year-on-year to 350 applicants following the success of the previous two programs. 45 aspiring businesswomen from across Putaendo county were selected to participate in the program.

Los Andes also renewed and expanded its partnership aimed at developing mining-related skills at local high schools and universities, in collaboration with key national organizations. The partnerships aim to improve young people’s access to quality education and training opportunities that prepare them for careers in the modern mining industry.

In 2024, agreements were signed with two communities in Putaendo that own large parcels of land with the aim of working together to advance work on outdoor recreation projects and the conceptual study of environmental offset opportunities for the Vizcachitas Project. The Company can report that the work has shown potential for collaborative environmental stewardship, and it has renewed the agreements to further advance the opportunities that arose. The collaboration agreement with a local water association in the Putaendo Valley was also renewed.

During the year the Company organized a landmark seminar titled ‘Agriculture and Mining: Collaboration and Synergies of Two Engines of Regional Development’, facilitating important discussions on the compatibility and complementary nature of mining and farming activities in the Valparaíso Region. The event brought together local farmers, business leaders, and the heads of all major national business organizations, including commerce, agriculture, industrial, and mining sectors.

Sankamap Metals Inc. (CSE: SCU) (‘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. (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. For more information, please refer to SEDAR+ (www.sedarplus.ca), under Sankamap’s profile.
