Energy Ministry authorizes full temporary closure of Pinar del Río mine

The Ministry of Energy and Mines authorized the full temporary closure of the Polimetálicos Castellanos-Santa Lucía mine in Minas de Matahambre municipality, northern Pinar del Río. Resolution 49 of 2026 formalized the measure and was published in the Official Gazette. It affects Minera del Caribe S.A., or EMINCAR, and remains valid through January 30, 2027. The decision identifies the mine, affected joint venture and explicit period for closure.

The authorization is not presented as partial: the measure is defined as full and temporary. It is also linked to a numbered act, Resolution 49 of 2026, and official publication. For EMINCAR, the provision establishes a period ending January 30, 2027. These elements identify the measure's scope and the site to which it applies: Polimetálicos Castellanos-Santa Lucía in Minas de Matahambre.

Minera del Caribe S.A., also known as EMINCAR, was created in 2016 as a joint venture. State company Geominera S.A. holds 51 percent, while Trafigura owns the remaining 49 percent. Trafigura is described as a group of Dutch origin headquartered in Singapore. The ownership structure distinguishes the company affected by the measure from its two partners. The percentages account for the complete stated ownership, with Geominera holding the larger share.

The provision identifies the authority approving the measure, mine involved, affected company and maximum period of validity. The project's name, municipality and province place the closure at a specific point in Pinar del Río. The measure remains full and temporary, and January 30, 2027, is tied to its validity. Resolution 49 of 2026 is the administrative instrument cited to formalize the decision.
