Gold Resource Corporation Expands Arista Mine With Additional Switchback Step-Out Drill Intercepts Including 5 Meters of 3.98 g/t Gold

COLORADO SPRINGS, CO--(Marketwired - Feb 1, 2017) - Gold Resource Corporation ( NYSE MKT : GORO ) (the "Company") today announced the continued expansion of its Switchback vein system with additional step-out drill intercepts at the Aguila Project's Arista Mine. These new results, which mark the Company's farthest step-out drill hole to date, intercepted multiple veins including 5.01 meters of 3.98 grams per tonne (g/t) gold, and extends the Switchback system's total strike length to over 575 meters, a 275 meter expansion on strike since January 1, 2017. Gold Resource Corporation is a gold and silver producer, developer and explorer with operations in Oaxaca, Mexico and Nevada, USA. The Company has returned $109 million to shareholders in monthly dividends since commercial production commenced July 1, 2010, and offers shareholders the option to convert their cash dividends into physical gold and silver and take delivery.

From an underground exploration drill pad located on level 14 of the Arista Mine's Arista vein system, drill Holes 516150 and 516148 targeted extensions of the Switchback vein system. Multiple veins were intercepted in each hole significantly extending the Switchback vein system mineralization to the northwest (see map). Hole 516150 extended the system northwest by approximately 75 meters on strike beyond the recently released step-out Hole 516147 (see January 12, 2017 Press Release), which added approximately 200 meters of strike length to Switchback. These new intercepts expand the Switchback system strike length from its previous 300 meters of strike length to now over 575 meters of total strike. The Switchback vein system remains open in all directions.

"These are substantial step-out drill holes into a powerful, growing epithermal vein system," stated Mr. Barry Devlin, Vice President of Exploration for Gold Resource Corporation. "Intercepts including 5 meters of 3.98 grams per tonne gold and 8.78 meters of 1.46 grams per tonne gold indicate substantial vein widths for underground mining along with excellent grades. We are very excited to be expanding the Switchback vein system as the Arista Mine continues to grow."

"We are thrilled to add another 75 meters on strike of high-grade veins at our Switchback vein system," stated Mr. Jason Reid, President and CEO of Gold Resource Corporation. "Hole 516150 represents over 275 meters of vein system strike expansion since the first of the year, an increase in strike of over 90% since January 1, 2017. As I have referenced in the past, the discovery outcrop of the Switchback structure is evident in a ridge now over 200 additional meters further on strike to the northwest from this new intercept in drill Hole number 516150. As these high-grade mineralized veins continue to expand, they may not only extend underneath the surface expression of Switchback, but may continue further along strike as well. We have speculated that the Switchback vein system could over time become every bit as large as, or larger than, the Arista vein system. We are pleased and excited these continued step-out intercepts substantially grow and expand our Arista Mine."
