Mirador Mine

Gold Resource Corporation's Mirador underground mine is located at the Company's Alta Gracia Project in the southern state of Oaxaca, Mexico. Oxide mineralization from the Mirador mine is trucked to and processed in the Aguila Mill's agitated leach circuit. Initial mining rates target 100 to 200 tonnes per day and an initial mill processing rate of 150 tonnes per day. The Mirador mine has the potential to increase the Company's future annual silver production by approximately 500,000 silver ounces and 1,000 gold ounces. At December 31, 2016, Alta Gracia reserves were estimated at 43,800 tonnes in the proven and probable category grading 1.06 grams per tonne (g/t) gold and 342 g/t silver; and 296,900 tonnes in the mineralized material category grading 0.36 g/t gold and 232 g/t silver.
