 14,589 ounces AuEq sold

 $23.3 million sales, net

 $1.6 million operating income

 $533 total cash cost per ounce AuEq (after by-product credits)

Overview of Q2 2015 Aguila Project Results

Gold Resource Corporation's Aguila Project produced 14,858 ounces AuEq at a total cash cost of

$533 per ounce (after by-product credits). Realized average metal price sales during the quarter were $1,201 per ounce gold and $16.70 per ounce silver. The Company recorded net income of

$0.8 million, or $0.01 per share. Cash Flow from Mine Site Operations totaled $9.4 million. The Company paid $1.6 million to shareholders in dividends, or $0.03 per share during the quarter. Cash and cash equivalents at quarter end totaled $21.0 million. Realized gold and silver prices decreased 5.9% and 11.9%, respectively, compared to the second quarter of 2014.

"Second quarter 2015 production was weaker than expected due to challenges including water inflow management, slower than expected mine development and an illegal mine protest and work stoppage," stated Gold Resource Corporation's CEO and President, Mr. Jason Reid. "Halfway through the 2015 production year, the Company has produced 15,135 ounces of gold and

1,370,625 ounces of silver, delivering approximately 96% of expected gold production and 92% of

1

expected silver production of the Company's lower range 2015 annual Outlook. Many of the challenges during the second quarter are behind us, such as the ancillary effects of the protest and work stoppage and third quarter mine improvements are underway, including implementing long- term solutions to help remediate the excess water issues. The Company believes the lower range of its 2015 annual production Outlook is within reach."

(1) Mill production represents metal contained in concentrates produced at the mill, which is before payable metal deductions are levied by the buyer of our concentrates. Payable metal deduction quantities are defined in our contracts with the buyer of our concentrates and represent an estimate of metal contained in the concentrates produced at our mill which the buyer cannot recover through the smelting process. There are inherent limitations and differences in the sampling method and assaying of estimated metal contained in concentrates that are shipped, and those

2

contained metal estimates are derived from sampling methods and assaying throughout the mill production process. The Company monitors these differences to ensure that precious metal mill production quantities are materially correct.

(2) Average metal prices realized vary from the market metal prices due to final settlement adjustments from our provisional invoices when they are settled. Our average metal prices realized will therefore differ from the market average metal prices in most cases.

(3) Precious metal gold equivalent mill production for the three months ended June 30, 2015 differs from gold equivalent ounces sold for the same period in 2015 due principally to buyer (smelter) concentrate processing and other deductions of approximately 1,116 gold equivalent ounces and a decrease in gold equivalent ounces contained in ending inventory of approximately 268 ounces.

(4) Precious metal gold equivalent mill production for the six months ended June 30, 2015 differs from gold equivalent ounces sold for the same period in 2015 due principally to buyer (smelter) concentrate processing and other deductions of approximately 2,438 gold equivalent ounces and a decrease in gold equivalent ounces contained in ending inventory of approximately 814 ounces.
