Fourth Quarter 2021 Production Highlights

• 405 tonnes of payable copper
• 2,059 tonnes of payable lead

Allen Palmiere, President and CEO, said, “As I reflect on my first year at Gold Resource Corporation, I am pleased with the results of the Don David Gold Mine and the acquisition of Aquila Resources Corporation. Despite ground control challenges and the voluntary temporary shutdown due to COVID-19 in late August and early September, our Mexican operation still achieved the high end of guidance for gold production. Throughout the year, the team took a disciplined approach to identifying opportunities for improvements and implementing efficiencies. Our exploration investment has shown great promise and has given us excellent targets for our 2022 in-mine and near mine drill program. In addition, the completion of the filtration plant and dry stack facilities advances our environmental stewardship efforts. I am optimistic about 2022 as we continue to plan for our future in Oaxaca and advance the definitive feasibility study for the Back Forty Project in Michigan.”

Sales Statistics

(1) Average metal prices realized vary from the market metal prices due to final settlement adjustments from our provisional invoices. Our average metal prices realized will therefore differ from the average market metal prices in most cases.

Production Statistics

(1) Based on actual days the mill operated during the period.

(2) The difference between what we report as "Metal Production" and "Metal Sold" is attributable to the difference between the quantities of metals contained in the concentrates we produce versus the portion of those metals actually paid for according to the terms of our sales contracts. Differences can also arise from inventory changes related to shipping schedules, or variances in ore grades and recoveries which impact the amount of metals contained in concentrates produced and sold.
