On January 26, 2026, Gold Resource Corporation announced it has entered into a definitive arrangement agreement and plan of merger with Goldgroup Mining Inc. whereby Goldgroup has agreed to acquire all of the issued and outstanding shares of Gold Resource’s common stock in an all-stock transaction.  The transaction values Gold Resource’s common stock at approximately US$372 million on a fully-diluted in-the-money basis and based on the value of Goldgroup shares on January 23, 2026.

The proposed transaction will occur by way of a reverse triangular merger in which Gold Resource will merge with a wholly owned subsidiary of Goldgroup under Colorado law and a plan of arrangement under the Business Corporations Act (British Columbia), with Gold Resource surviving as a wholly owned subsidiary of Goldgroup.

Cormark Securities acts as financial advisor to Gold Resource, with Davis Graham & Stubbs, Cassels Brock & Blackwell, and Sánchez Mejorada, Velasco y Ribé as its U.S., Canadian, and Mexican legal counsel, respectively, while Cozen O’Connor and McMillan advise Goldgroup and its special committee, with Fort Capital Partners providing a fairness opinion.
