“These age-date results are proof of our concept that our properties are part of a continuous belt of caldera systems that have shown exceptional potential for hosting bonanza grade Au-Ag epithermal deposits,” said

The results indicate that:
- The 3 calderas associated with Gold Resource Corp.’s active Arista-Switchback mine and related epithermal systems all developed between approximately 19-18 Ma (million years ago).
- The caldera system associated with the Company’s
Yautepec project developed in a similar age range of approximately 19-18 Ma.- The similarities in ages indicate that the area of Gold Resource Corp.’s producing mines and Madoro’s
Yautepec entire project area is part of a singular magmatic-structural-hydrothermal system spanning 60-kilometers distance; the entire trend may be considered to have similar potential for high-grade epithermal Au-Ag polymetallic deposits
Accompanying Figures 1-3 show, respectively, the locations of identified caldera systems relative to active mining and exploration efforts, the locations of samples for the age dates in Table 1, and our inference of the significance of these results.
