The high-grade polymetallic Switchback vein system expands the currently producing Arista Mine mineralization (see map). The Company continues to develop a second drift to access Switchback and targets to crosscut and mine this mineral in the second half of 2016, dependent on drift progression, rock competency, potential water courses and CO2 gas that may be encountered during development. Thus far no appreciable amounts of water or gas have been encountered, though the Company does expect water management to be necessary in the future. 

These infill and step-out drill results from Switchback confirm continuity of modeled veins and expand previously defined mineralization. The Switchback vein system remains open in all directions, and the Company continues to drill the extensions of this expanding vein system. At December 31, 2015, the Company reported mineralized material at Switchback in excess of 630,000 tonnes. 

Mr. Barry Devlin, Vice President of Exploration, stated, “Exploration at Switchback continues to deliver impressive results defining high-grade polymetallic mineralization over multiple parallel veins. These latest drill results also include some of the widest intercepts we have seen to date in the Switchback swarm of veins. Our exploration team’s goal for Switchback is to continue drilling the extensions of this expanding epithermal system. If we reach the Switchback veins with development in time for the next reserve update, we target a conversion of a portion of Switchback’s mineralized material into proven and probable reserves.”

“The substantial vein widths and continued high-grade mineralization in these latest Switchback drill results further substantiate our belief that the Arista Mine is part of a very large and powerful epithermal system,” stated Gold Resource Corporation’s CEO and President, Mr. Jason Reid. “Expansion of this system should provide for longevity of operations at our producing Arista mine along with other potential mines in this large system like Alta Gracia from which we target near-term production as well. We continue to advance Arista mine development targeting first Switchback ore feed for the Aguila mill during the second half of 2016.”
