#### GOLD RESOURCE CORPORATION REPORTS STRONG INITIAL PRODUCTION FROM THE THREE SISTERS AREA AT THE DON DAVID GOLD MINE
<br>**Denver, Colorado – December 3, 2025 – Gold Resource Corporation (NYSE American: GORO)** (the "**Company**," "**we**," "**our**," or "**GRC**") is pleased to report strong production results for the past two weeks, as mining advances into the high-grade Three Sisters area at the Don David Gold Mine in Oaxaca, Mexico.

"The production values we have seen over the past two weeks confirm and validate the potential upside of the Three Sisters area," stated Allen Palmiere, President and CEO. "While these exceptional results exceed what we expect on a sustained basis, they underscore the conservatism of our geological modelling and mine planning in addition to highlighting the potential of this zone to generate significant cash flow."

**Don David Gold Mine Mexico - Production Statistics November 8 to 24, 2025**

During the two-week period operations delivered strong results, exceeding the mines planned tonnage and grades referred to below as Net Smelter Return ("NSR") value in USD.

**November 8–14**

● 4,357 tonnes mined and 6,769 tonnes processed at an average NSR of $1,512 per tonne

● The NSR is 129% higher than modelled

**November 15–21**

● 6,580 tonnes mined and 6,095 tonnes processed at an average NSR of $723 per tonne

● The tonnes mined is 40% higher and the NSR 91% higher than planned and modelled.

**Back Forty Project Michigan - Development Update**

The Company has made a strategic decision to resume work on the Back Forty Project in Michigan. The Company is in discussions with consulting firms to complete a feasibility study and is planning on beginning the permitting process. A technical report summary for the Back Forty Project was filed in October 2023 and included a cash flow model based on $1,800 gold and $1.25 Zinc. The sensitivity analysis indicated that a 50% increase in the price of gold to $2,700 increased the net present value of the project by over 100% to approximately $430 million. While the economics were attractive when the study was completed, the project is much more robust at current consensus metal prices assumptions.
