Overview of 2012 Results from El Aguila Project

“Our Arista mine completed its first full year of underground mining in 2012 but not without its share of challenges. Though 2012 marked a record production year, we had to deal with greater than expected water flows and unexpected and substantial carbon dioxide gas that required increased pumping and increased ventilation for safe operations,” stated Gold Resource Corporation President, Mr. Jason Reid. “Our approximate 37% increase over last year’s mill production evidences the turnaround that took place after issues in the mine slowed down development during the second quarter. I would like to thank our new team that came on board in 2012 headed by our Chief Operating Officer Mr. Rick Irvine and our new General Manager Mr. Jesus Rivera and the rest of our new on-site management team in Oaxaca that produced these results in spite of various challenges. Ramping up a mining operation, particularly an underground mine, is not an easy task. However, at the end of the day, it is people that make the difference and I believe we have retooled our organization with a hand-picked team well-suited to meet the challenges ahead. The results for the year underscore our ability to overcome challenges and execute the Company’s business plan.”

For 2012, Gold Resource Corporation sold of 72,399 ounces of precious metal gold equivalent (AuEq), at a total cash cost of $419 per gold equivalent ounce.

Mr. Jason Reid added, “These results allowed management to continue our shareholder focused philosophy by distributing record dividends in 2012 of $36.5million, or $0.69 per share. In 2012, we took our dividend option one step further by allowing shareholders to convert their cash dividends into physical gold and/or silver and take delivery of their precious metals.”

(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. In addition, mill production quantities for the year ended December 31, 2012 do not reflect any deduction for 583 gold ounces, respectively, and 45,432 silver ounces, respectively, (approximately 1,400 gold equivalent ounces) resulting from the settlement agreement with the buyer of our concentrates as discussed on page 30 under “Settlement with Concentrate Buyer”. Gold equivalent ounces sold for the year ended December 31, 2012 have been reduced by approximately 1,400 gold equivalent ounces as a result of the settlement.

(2) A reconciliation of this non-GAAP measure to mine cost of sales, the most comparable GAAP measure, can be found inNon-GAAP Measures in the Form 10-K for the period ended December 31, 2012. Total cash cost per gold equivalent ounce sold for the combinedLa Arista underground mine and theEl Aguilaopen pit mine for the for the year ended December 31, 2011, can be found in the Form 10-K for the period ended December 31, 2012.

(3) Gold equivalent mill production for 2012 of 90,432 ounces differs from gold equivalent ounces sold for 2012 of 72,399 due principally to buyer (smelter) concentrate processing deductions of approximately 9,078 gold equivalent ounces, a settlement agreement with the buyer of the Company’s concentrates of approximately 1,400 gold equivalent ounces and an increase in gold equivalent ounces contained in ending inventory of approximately 7,555 ounces

Overview of Q4 2012 Results from El Aguila Project

Fourth quarter production from the El Aguila Project totaled 23,782 ounces AuEq at a cash cost of $551 per ounce AuEq and realized average sales prices of $1,691 per ounce gold and $36 per ounce silver. The mine generated gross profit of $17.2 million. The Company paid $9.5 million to shareholders in dividends, and repurchased 149,407 shares at an average share price of $16.30.

2013 Production Outlook

The Company’s 2013 production target is between 80,000 to 100,000 ounces AuEq. The target range was estimated based on the Company’s 2013 mine plan, the area of the deposit scheduled to be mined during the upcoming year and the planned mill expansion goals with associated down time for construction. The Company is targeting to be in the lowest quartile of total cash cost per ounce ranging from $300 to $500 per ounce AuEq in 2013. Cost cutting measures and production increases are being targeted to lower costs. (Total cash cost per ounce is a Non-GAAP Financial Measure. Please see additional information in Management’s Discussion and Analysis and Results of Operation in the Company’s annual report on Form 10-K for the period ended December 31, 2012).

Project Update

The Company views 2013 as an important year of improvements both at the mine and in the mill. The plan is to position the Project to nominally produce 1,500 tonnes/day by the end of the year. Expected mine development of the Arista deposit is to the south and southeast and this area is anticipated to provide the ore for production in 2013. The Company is targeting higher grade ore shoots located further southeast in the deposit in the 2014 production year. Currently the decline ramp is down to level 15 and stopes are being developed from level 10 down to level 13.

As has been the case over the last two years, the Company continues to upgrade its El Aguila mill. The Denver based engineering firm Lyntek Inc., who served as the Company’s Engineering, Procurement, Construction Manager for the original 2008-2009 mill construction, has been contracted and is on site to complete these 2013 upgrades. Significant planned upgrades to the mill include an additional ball mill to the grinding circuit, thickener surge tanks and additional float cell capacity as the Company targets increased production tonnages by the end of 2013. Although the Company does not plan to shut the flotation mill down for extended periods of time, construction activities will periodically impact daily production. An end of year construction completion goal has been set with a preliminary budget of approximately $6 million. Any extended mill shut down for construction, or for any other reason, could affect targeted 2013 production.

2012 Exploration Program

A total of six exploration drills are currently at the Company’s properties. Three surface drills and two underground drills are concentrated at the Arista mine. The sixth drill is at the Las Margaritas property. The Company targets a $10 million budget for exploration at its Oaxaca Mining Unit for 2013.

Most of the new mineralization that is being encountered with this drilling around the Arista vein system is adding new ounces and expanding upon the July 2012 estimated third party resource that was performed by Pincock, Allen and Holt to Canadian NI 43-101 standards.

At Las Margaritas, initial surface sampling by the Company identified mineralization containing up to 4,150 grams per tonne silver and 6.29 grams per tonne gold. In 2012, the Company completed fifteen surface diamond drill holes totaling 5,002 meters on the Las Margaritas property. High-grade mineralization was encountered with drill intercepts including 27.90 grams per tonne gold and 2,600 grams per tonne silver over a core length of 2.85 meters. In 2013, drilling will continue at Las Margaritas to test various structural and mineralized exploration targets.

The Company is also completing a property-wide airborne geophysical survey spanning along the 48 kilometer structural corridor identified on its properties.
