GOLD RESOURCE CORPORATION ANNOUNCES SPECIAL SHAREHOLDER MEETING TO VOTE ON STRATEGIC MERGER WITH GOLDGROUP MINING
With Proxy Materials Officially Being Mailed, the Board Urges Shareholders to Vote “FOR” the Milestone Deal That Will Combine Core Assets and Drive Long-Term Shareholder Value
DENVER – June 5, 2026 – Gold Resource Corporation (NYSE American: GORO) (the “Company,” “we,” “our,” or “GRC”) today announced updates regarding our upcoming Special Meeting of Shareholders (the “Special Meeting”) scheduled for July 2, 2026. The definitive proxy statement has been filed with the Securities and Exchange Commission (the “SEC”), and mailing has been completed to shareholders of record as of May 26, 2026.
The Goldgroup Merger: Unlocking Shareholder Value
Following the finalization of the definitive transaction documentation, the Company is moving into the final approval phase of its strategic combination. Under the terms of the Arrangement Agreement and Plan of Merger dated January 25, 2026, as amended on May 15, 2026, the Company will combine with Goldgroup Mining Inc. (TSX-V: GGA; OTC: GGAZF) (“Goldgroup”) via a reverse triangular merger with Goldgroup Merger Sub, Inc., a wholly owned subsidiary of Goldgroup (the “Merger”).
Management believes that the proposed Merger represents a net benefit for the Company’s shareholders:
| · | Direct Share Exchange: GRC stockholders will receive 1.4476 common shares of Goldgroup for each share of GRC common stock they own (subject to adjustment for a share consolidation to be completed by Goldgroup at a ratio to be determined jointly by Goldgroup and the Company, and approved by the TSX Venture Exchange, prior to closing of the Merger). |
| · | Enhanced Operational Scale: The proposed Merger creates a consolidated precious metals company with stronger asset utilization, expanded exploration potential, and a unified platform built to navigate dynamic mining markets. |
| · | Continued Upside Exposure: Shareholders will retain significant ongoing equity ownership in the combined enterprise, allowing them to benefit directly from future growth, anticipated cost synergies, and broader market visibility. |
“The filing and mailing of our definitive proxy statement marks a critical milestone toward completing this transformative transaction,” said Allen Palmiere, CEO, President & Director of the Company. “Having successfully executed a turnaround at the Don David Gold Mine, we are positioned to expand production through the proposed Merger. The addition of Goldgroup’s San Francisco mine and Cerro Prieto mine is expected to increase gold exposure and materially enhance cash generation through higher overall output.”
The Board of Directors of the Company has thoroughly reviewed the proposed Merger and strongly urges GRC’s shareholders to vote “FOR” the proposals within the definitive proxy statement.

What Our Shareholders Are Voting On
At the upcoming Special Meeting, our shareholders will be asked to consider and vote upon:
| 1. | The Merger Proposal: To approve the Arrangement Agreement and Plan of Merger. |
| 2. | The Merger-Related Compensation Proposal: To approve, on a non-binding advisory basis, the merger-related executive compensation. |
| 3. | The Adjournment Proposal: To approve the adjournment of the Special Meeting to a later date, if necessary, to solicit additional proxies for the approval of the Merger Proposal. |
Your Vote is Required—How to Cast It Now
Because approval of the Merger Proposal requires a definitive majority threshold of all outstanding shares to pass, not voting has the exact same effect as voting “AGAINST” the Merger. Every single vote matters, regardless of how many shares you own.
Shareholders are highly encouraged to submit their proxy votes ahead of time using one of the following quick methods:
| · | Vote Online: Go to the secure website listed on your proxy card or voting instruction form and enter your unique control number. |
