Gold Resource Corporation (NYSE:GORO) (the "Company," "We," "Our" or "GRC") remains focused on unlocking the value of our Mexican mine, existing infrastructure, and large property position. Additionally, the Company remains committed to optimizing the mine plan and process flowsheets for the Back Forty Project. With that said, the 2022 market volatility, challenging economic conditions and the lower grade profile of our current Mineral Reserves and Mineral Resources, have collectively contributed to an adverse impact on our 2022 cash flows and consolidated earnings. While we are focused on organic growth and disciplined cost cutting initiatives, the lower grade profile is expected to continue through 2023 and is projected to negatively impact operating cash flows and total cash costs per gold equivalent ounce, as reflected in the guidance table below.

Allen Palmiere, President and CEO, said, "2022 was a challenging year for the Company on a number of fronts; however, we made excellent strides with our operations, capital and exploration programs. Further, I remain very proud of how our workforce embraced our objectives and values around safety, operational process improvement and collaboration with our internal and external stakeholders. We will continue identifying operational efficiencies and cost improvement opportunities in 2023; however, as per our 2023 guidance, lower gold grades will result in less production in 2023 than 2022 and further significantly contribute to an increased Cash Costs and All-in Sustaining Costs. More importantly, we are eager to advance the exploration drilling at a number of highly prospective underground targets in Mexico. With the Back Forty Project, we will continue work on the feasibility study with a deliberate and measured approach. I remain optimistic that this year will provide opportunities to grow the Company in new directions."

Measure	2023 Guidance
Payable Production	17,000 to 19,000 Gold Ounces 900,000 to 1,000,000 Silver Ounces 30,000 to 31,000 Gold Equivalent Ounces
Cash Costs after by-product credits per gold equivalent ("AuEq") ounce ^{1, 2}	$1,000 to $1,050
All-in Sustaining Costs after by-product credits per AuEq ounce ^{1, 2}	DDGM: $1,250 to $1,350 Consolidated: $1,650 to $1,750
Capital Investment	$6 to $7 million
Exploration Commitment	$3 to $4 million Sustaining $6 to $7 million Growth

Calculations of cash cost after co-product credits per gold equivalent ounce and all-in sustaining cost after co-product credits per gold equivalent ounce are non-GAAP financial measures. Please see the "Management's Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Measures" for a complete definition and explanation of non-GAAP measures and how they reconcile to U.S. GAAP.

Co-product credits directly impact the Cash Costs and AISC per AuEq ounce calculation. Guidance is based on approximately 4,200 tonnes of lead sold at an $0.91 per pound metal price, approximately 1,200 tonnes of copper sold at a $3.80 per pound metal prices, and 11,200 tonnes of zinc sold at a $1.40 per pound metal price.

We continue to be optimistic that underground exploration targets will return favorable results that will both provide improved overall mineral grades and extend the life of the mine. In 2022, we faced several technical challenges that slowed drift extensions to multiple underground targets. Those technical challenges have been addressed and we are well positioned to conduct step-out drilling in multiple highly prospective areas of Switchback and Arista. These targets are higher in the vein systems where we have historically seen higher precious metal grades.

At this time, the Board of Directors and Management feel the best way to maximize shareholder value is to protect our balance sheet and focus our capital resources on exploration and growth opportunities. Therefore, we will suspend the quarterly dividend until such time that it may become practicable to reinstate.
