Gold Resource Corporation Reports Improved Year Over Year Financial Results and Strong Balance Sheet for the Second Quarter 2022

• CASH BALANCE OF OVER $33.3 MILLION AFTER OVER $15 MILLION INVESTED IN CAPITAL AND EXPLORATION
• OPERATING CASH FLOW OF $12.2 MILLION AND EBITDA OF $29.0 MILLION
• REITERATE 2022 PRODUCTION AND COST GUIDANCE

DENVER--(BUSINESS WIRE)--Gold Resource Corporation (NYSE American: GORO) (the “Company”) sold a total of 8,746 ounces of gold and 231,622 ounces of silver in Q2 2022 for a gold equivalent total of 11,475 ounces. Additionally, the Company sold 3,590 tonnes of zinc, 286 tonnes of copper, and 1,755 tonnes of lead.

Allen Palmiere, President and CEO said “Production remains solid at the Don David Gold Mine in Mexico with significant improvements in financial measures over the same period last year. The volume of tonnes processed during the quarter declined slightly from Q1 as we continue to address ground support challenges common to our type of mineral deposit. Grades and improved recoveries helped ensure we delivered another quarter of over 10 thousand gold equivalent ounces. We continue to be committed to having a disciplined focus on costs in the current inflationary market and would like to reiterate our 2022 guidance. Likewise, our continued reinvestment into exploration and infrastructure improvements at the Don David Gold Mine and progressing the feasibility study and permitting initiatives at the Back Forty Project in Michigan are focused on favorably impacting our environment, social and governance programs while creating operational efficiencies and longevity.”

Q2 2022 HIGHLIGHTS

Additional highlights for the second quarter ended June 30, 2022, are summarized below:

• Total cash cost for the quarter was $247 per gold equivalent (“AuEq”) ounce (after co-product credits) and total all-in sustaining cost for the quarter was $799 per AuEq ounce (after co-product credits). Both non-GAAP measures were favorably impacted by higher co-product credits for base metals sold.¹
• For the eighth consecutive year, the Don David Gold Mine (“DDGM”) earned the prestigious Empresa Socialmente Responsable (“ESR”) award from the Mexican Center for Philanthropy (CEMEFI). Awards are given to organizations who demonstrate a commitment to supporting social and environmental protection programs within their local communities.
• During the quarter, the Company continued to process tailings material from a nearby community in an effort to ensure the proper environmental treatment and storage of the material.
• The Company’s Annual Meeting of Shareholders was held in person on May 19, 2022. During the meeting, shareholders approved the current five Directors to serve another annual term and ratified the appointment of BDO USA, LLP as the independent auditor for the fiscal year ending December 31, 2022.
• $0.9 million was distributed in shareholder dividends this quarter, totaling over $121 million since 2010.
• Working capital was $37.1 million as of June 30, 2022, $7.8 million higher than as of December 31, 2021. The increase is primarily due to a decrease in the liability related to the zinc zero cost collar.

The Company’s investment in Mexico continued in Q2 2022 totaling $12.6 million year-to-date. Our investment in Mexico is focused on favorably impacting our environment, social and governance programs while creating operational efficiencies and longevity. Year-to-date at the Back Forty Project, $3.1 million has been invested in feasibility and permitting initiatives.

Gold Regrind Project: Zinc tailings are being reground and leached to produce doré bars. Gold recovery is expected to continue to increase, and we have seen an approximate 5% increase in the gold recovery since the same period in 2021. Completion and commissioning were finalized in Q2 2022. A total of $1.8 million was invested in this project, $1.1 million in 2021.

Dry Stack Tailings Project: Construction of the tailings filtration plant and dry stack facility were completed in 2021. During the first half of 2022, work continued to optimize the operations of the filtration plant. Currently 85% of the tails are sent to the dry stack facility, and the remaining 15% is sent to the underground operations in the form of paste fill for ground support. The dry stack facilities will conserve and recirculate water, eliminate risks related to traditional tailings facilities, accelerate reclamation of certain areas of the open pit mine, and extend the life of the operations. As of June 30, 2022, a total of $15.1 million has been invested in this project, $14.0 million through 2021.

Underground and Exploration Development: Mine development during the quarter included ramps and accesses to different areas of the deposit, vertical shafts, and exploration development drifts. A total of 2,346 meters of development, at a cost of $5.3 million (1,252 meters at a cost of $2.9 million in Q2), was completed during the first half of 2022. For the first half of 2022, underground mine development was $3.2 million and exploration development was $2.1 million (included in Infill Drilling and Exploration Development in the table above). We plan to invest a total of $8.5 million to $9.5 million in underground development and an additional $4.0 million to $4.5 million in exploration development in 2022.

Back Forty Feasibility and Permitting: Work on the optimized feasibility study progressed during Q2 2022. Current initiatives are focused on mine planning and process plant design. Environmental considerations are a key factor in the overall site layout and infrastructure decisions being made. The feasibility study work for the Back Forty Project in Michigan, USA progressed during Q2 2022 with completion expected in the second half of this year, followed by permit applications being submitted with state agencies in Michigan.
