COLORADO SPRINGS – July 12, 2013 – Gold Resource Corporation (NYSE MKT: GORO) (the “Company”) announces today it has received a copy of a Form 144 filed with the U.S. Securities and Exchange Commission indicating the sale of 3.4 million shares of common restricted stock by its largest shareholder. The Company has returned over $85 million to shareholders in monthly dividends since declaring commercial production July 1, 2010, and offers shareholders the option to convert their cash dividends into physical gold and silver and take delivery.

The Form 144 was filed by Hochschild Mining Holdings Ltd. and indicates a sale of approximately 3.4 million shares of the Company’s common stock in accordance with the Rule 144 of the Securities Act of 1933, as amended. Generally, Rule 144 allows holders of restricted securities to sell shares in the market after a certain holding period and so long as the requirements of the rule are met. Certain shareholders, including those holding more than 10% of the Company’s outstanding shares, are subject to further volume limitations which restrict the number shares that can be sold in the market every three months, which is the greater of 1% of the outstanding shares or the average weekly trading volume of the securities during the fourweekperiod prior to the sale. Pursuant to these volume limitations provided by Rule 144, the Company believes Hochschild’s sale of 3.4 million shares is near the maximum number of shares eligible for sale in the market for this 90 day period.
