Gold Resource Corporation (NYSE:GORO) (the "Company") sold a total of 30,119 ounces of gold and 1,057,209 ounces of silver in 2022 for a gold equivalent total of 42,757 gold equivalent ounces. Additionally, during the year the Company sold 14,157 tonnes of zinc, 1,348 tonnes of copper, and 5,391 tonnes of lead contributing to a strong cash balance of over $23 million.

Allen Palmiere, President and CEO said "Despite global challenges faced this year, such as inflation, and localized challenges such as ground support and ventilation, gold and silver production at the Don David Gold Mine in Mexico still ended the year above guidance. While our grade profile is expected to decline in 2023, we continue to identify and implement improvement opportunities, including collaborating with local communities to ensure sustainability. Work continues with the feasibility study to advance the Back Forty Project in Michigan and once completed, preparation of State of Michigan permits will follow. In addition to the feasibility study work, we continue to focus on engaging with the local community."

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

(3) 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.
