Mineros S.A. Updates Market on Special Meeting of Shareholders Scheduled for April 30, 2026, and Confirms Successful Closing of Previously Announced Transaction

MEDELLÍN, Colombia--(BUSINESS WIRE)--Mineros S.A. (TSX:MSA, OTCQX:MNSAF, BVC:MINEROS) (“Mineros” or the “Company”) provides an update regarding the Special Meeting of Shareholders (the “Meeting”) scheduled for April 30, 2026, and confirms successful closing of previously announced transaction.

Status of Corporate Evaluation

The Board of Directors and management of the Company continue their formal evaluation of a potential corporate re-domiciliation or related reorganization. This comprehensive assessment involves the analysis of legal, fiscal, regulatory, and operational implications across multiple jurisdictions.

As of this date, the Board’s internal investigations and due diligence processes remain ongoing. Consequently, no final determination has been made to proceed with a reorganization, and no Management Information Circular will be delivered to shareholders.

Procedural Requirements and Meeting Logistics

The convening of the Meeting on April 30, 2026, was necessitated by specific regulatory and corporate law frameworks. Under applicable law, the Company’s audited financial statements as of December 31, 2025, serve as the formal basis for any potential merger. To use these statements, a shareholders’ meeting must be convened within a strictly prescribed period following the fiscal year-end.

The Meeting was therefore called on a precautionary basis to preserve procedural flexibility and ensure compliance with these statutory timelines, independent of the final status of the Board’s evaluation. Accordingly, no statutory merger for the purpose of re-domiciliation will be put forward to shareholders at this time.

Successful Closing of the Acquisition of AngloGold Ashanti Colombia S.A.S.

Mineros is pleased to announce that, on April 13, 2026, it successfully closed the previously announced acquisition of 100% of the issued and outstanding shares of AngloGold Ashanti Colombia S.A.S., from a subsidiary of AngloGold Ashanti PLC pursuant to the definitive agreement entered into on March 7, 2026. Through this transaction, which was completed on the previously announced terms, Mineros has added to its portfolio an exploration-stage gold project located in the municipality of Cajamarca, Department of Tolima, Colombia.

As noted in the Company's March 9, 2026 announcement, Mineros intends to initiate a collaborative process with local stakeholders to define a new project identity, including a new name, as part of its commitment to aligning development pathways with local priorities. Any advancement of the project remains contingent upon achieving regulatory clarity, environmental authorization, and meaningful community consensus.
