Gold Resource's Oaxaca Mine Faces Temporary Work Stoppage Due To Illegal Union-Contractor Blockade

Gold Resource Corporation (NYSE:GORO) (the "Company") announced today that an illegal blockade is underway at its mine in Oaxaca, Mexico that will affect production. The Company received notice from the CTM union that four contractors operating at the mine site are no longer affiliated with the union. Pursuant to the terms of the CTM union agreement, the Company issued termination notices to the four contractors who provide camp support, security, ore haulage, water haulage, and employee transportation. Approximately 20 employees of the terminated contractors established an illegal mine-access blockade, resulting in the work stoppage.

This dispute is between the union and four contractors who were previously affiliated with the union. This is not a dispute between the Company and the union nor between the Company and the four contractors. The Company is prepared to promptly resume mining and processing operations once the blockade is removed.

Gold Resource Corporation remains neutral in the internal dispute between union factions and continues to meet its contractual obligations while prioritizing site stability. The safety of personnel and the protection of the environment remain central to all decisions as the Company works toward a resolution. The Company believes this stoppage to be temporary, and further updates will be provided as conditions evolve.
