The Arista MineArista Mine Introduction Video a wholly owned subsidiary of GORO
Gold Resource Corporation's Arista underground mine is located at the Company's El Aguila Project in the southern state of Oaxaca, Mexico. The El Aguila Project mineralization occurs as structurally-controlled epithermal deposits in veins and stockwork zones consisting of concentrations of sulfides containing gold, silver, copper, lead and zinc, associated with gangue minerals such as quartz, calcite, and other minor elements.

Development of the Arista mine began in 2009, and initial production from the deposit began in March 2011. Ore is trucked approximately 2 kilometers to the Aguila mill where it is processed into three differential concentrates: a copper/gold; a lead/silver; and a zinc.
Since the initial discovery of the Arista and Baja veins in 2007, multiple additional en echelon veins have been discovered, many which have been mined or will be mined in the future. The Arista deposit is currently "open" in both strike and at depth. The deposit currently extends over 1 kilometer along strike, and over 600 meters at depth. The Company continues to drill the extensions of the Arista deposit to extend the mine life.

El Aguila Mill
Gold Resource Corporation currently processes all of the Arista underground mine ore through the flotation circuit at the Company's El Aguila mill. The plant was built near the mine site and consists of two separate production circuits: a differential flotation circuit (sulphide ores) and an agitated leach circuit (oxide ores). The current nominal capacity of the flotation circuit is 1,500 tonnes per day, while the agitated leach circuit has a nominal capacity of 300 tonnes per day.
The flotation circuit produces three types of high-grade concentrates: a copper concentrate with gold-silver; a lead concentrate with gold-silver; and a zinc concentrate with gold-silver. All concentrates are marketed to a broker in México.
The Aguila plant's agitated leach circuit is currently idle as the Company evaluates long-term sources of oxide ore.
