Gold Resource Corporation’s Alta Gracia Project Returns 10.30 Meters Grading 1,052 g/t Silver

COLORADO SPRINGS, Sept. 18, 2018 - Gold Resource Corp. (NYSE American: GORO) (the “Company”) today announced drill highlights from its 2018 Alta Gracia drill program located at its Oaxaca Mining Unit, Mexico. Drill highlights include 10.30 meters grading 0.85 grams per tonne (g/t) gold and 1,052 g/t silver, and 9.59 meters grading 0.36 g/t gold and 430 g/t silver. Gold Resource Corp. is a gold and silver producer, developer and explorer with operations in Oaxaca, Mexico and Nevada, USA. The Company has returned $111 million to its shareholders in monthly dividends since commercial production commenced July 1, 2010 and offers its shareholders the option to convert their cash dividends into physical gold and silver and take delivery.

The Alta Gracia Project, which hosts the Mirador Mine, is located approximately 16 kilometers north west of the Company’s Aguila Project and mineral processing plant. The 2018 Alta Gracia surface drill campaign tested several target areas focusing primarily on the Independencia and Victoria veins, located south west of the Mirador Mine, both of which we categorized as potential expansion areas for the Company’s producing Mirador Mine (see map below).

Highlights from the 2018 Alta Gracia surface drill campaign include the following intercepts (m = meters, g/t = grams per tonne) (see full tables below):

Hole # 418001 – Independencia Vein
10.30m of 0.85 g/t gold, 1,052 g/t silver
incl. 1.10m of 1.71 g/t gold, 3,620 g/t silver
incl. 1.90m of 1.60 g/t gold, 1,700 g/t silver

Hole # 418014 – Victoria Vein
5.18m of 0.55 g/t gold, 241 g/t silver
incl. 0.46m of 1.77 g/t gold, 373 g/t silver
incl. 0.82m of 0.83 g/t gold, 710 g/t silver

Hole # 418018 – Independencia Vein
9.59m of 0.36 g/t gold, 430 g/t silver
incl. 1.97m of 0.46 g/t gold, 568 g/t silver
incl. 1.60m of 0.57 g/t gold, 909 g/t silver

Hole # 418020 – Independencia Vein
2.70m of 1.67 g/t gold, 901 g/t silver
incl. 1.70m of 2.54 g/t gold, 1,405 g/t silver

Nine exploration drill holes targeted the Independencia vein, located approximately 500 meters south west along strike from the Company’s Mirador mine. The Company believes it has discovered a wide, high-grade silver ore shoot within the Independencia vein, and a significant potential expansion to the Mirador Mine. The Company is evaluating whether to develop this portion of the Independencia vein for mineral exploitation by improving and extending historic mine workings in this area.

Three exploration drill holes targeted the Victoria vein system, all which intercepted high-grade silver. In addition, four exploration drill holes targeted the Mirador vein system, which included the Mirador, Jarillas and Pitayos veins. Each drill hole intercepted multiple parallel veins, returning high-grade silver.

Mr. Barry Devlin, Vice President of Exploration, commented, “Our 2018 drill campaign at Alta Gracia was a success on many fronts, particularly the discovery of a wide, high-grade zone within the Independencia vein system and the potential expansion to the Mirador Mine. We also continue to see elevated levels of silver in the Mirador vein, as well as high-grade gold and silver within the Victoria vein system. We look forward to returning to Alta Gracia in 2019 with another drill program to continue expanding on these positive drill results.”

The Alta Gracia Project is one of six potential high-grade gold and silver properties in the Company’s Oaxaca Mining Unit, which includes over 684 square kilometers in southern Mexico. The Mirador Mine is the Company’s second operating mine, which began production in mid-2017.
