Gold Resource Corporation Issues 2020 Sustainability Accounting Standards Report

DENVER, September 24, 2021 - Gold Resource Corp. (NYSE American:GORO) (the "Company", "We", "Our" or "GRC") has released its 2020 Sustainability Disclosure Topics & Accounting Metrics ("2020 SASB Report"), which uses the Value Reporting Foundation's Metals & Mining Sustainability Accounting Standard of reporting to outline the Company's progress on its sustainability performance in 2020 at the Don David Gold Mine in Oaxaca, Mexico.

The team at Gold Resource Corp. holds itself accountable to the highest environmental, social and governance standards. Our commitment to acting responsibly and delivering excellence in sustainability allows us to deliver benefits to all our stakeholders, including our employees and local communities," said Allen Palmiere, President and Chief Executive Officer.

The Company's 2020 SASB Report, available at https://goldresourcecorp.com/responsible-mining/esg-reports/, highlights significant progress achieved by the Company in 2020 when compared with 2019, including:

1. A 38% decline in greenhouse gas emissions (or 23% decline related to tons of CO₂ equivalent produced per tonne of ore processed).
2. A 14.8% decline in the fresh water withdrawn per tonne of ore processed.
3. A 31% decline in the fresh water consumed per tonne of ore processed.
4. The percentage of tailings recycled through the paste plant rose to 26% from 5.7% in 2019.

The declines in tons of CO₂ equivalent are largely due to the conversion to the electrical grid from diesel generating capacity. We continue to focus on identifying opportunities to lower our power consumption and improve efficiency in this area. The declines in water consumption were due to the installation of the paste tailings plant as water is recycled back to the processing plant from this process.
