Gold Resource Corporation (NYSE American: GORO) (the “Company”) announces that the illegal blockade previously restricting access to its mine in Oaxaca, Mexico has been lifted, allowing mining and processing operations to safely resume.

The blockade, which was reported in the Company’s news release dated January 22, 2026, was initiated by approximately 20 employees of four contractors whose agreements were terminated following notice from the CTM union. The blockade was resolved without incident.

Gold Resource Corporation reiterates that the dispute was an internal matter between union factions and the contractors formerly affiliated with the CTM union and did not directly involve the Company. The Company remained neutral throughout the process.

Gold Resource Corporation extends its gratitude to employees, union members, community stakeholders, and governmental partners for their patience and assistance in resolving the situation.
