EMX's Ohakuri gold-silver property is located in the Taupo Volcanic Zone of New Zealand's North Island. The Ohakuri project is available for partnership. Ohakuri covers an area of historic drilling that intercepted broad zones of epithermal-style mineralization beneath a thin veneer of volcanic cover rocks. Several Au-Ag zones have been identified, and significant potential exists for continued discovery. Deposit type analogs include the bulk tonnage Round Mountain and McLaughlin gold deposits in the western U.S., where epithermal Au-Ag mineralization is also hosted by shallow-level volcanic deposits and sinters.

Previous explorers (including BP Minerals, Amoco, Cyprus, Delta Gold, Coeur Gold, GCO Minerals and Glass Earth) conducted drilling, geophysical surveys, geochemical sampling, geologic mapping and petrological studies that outlined a number of target areas anomalous in Au and Ag. The mineralization is hosted in ignimbrites and associated with quartz adularia alteration systems with weakly developed vein arrays.

Historic drilling totaling over 10,000 meters intersected zones of extensive silicification laced with auriferous quartz veinlets and phyllosilicate alteration. This drilling was guided by regional and prospect scale geophysical surveys, and largely targeted concealed bodies of mineralization.

Anomalous Au (+Ag) has been delineated in two principle areas: 1) Ohakuri North covering an area of 1000m X 500m, and 2) Ohakuri South covering an area of 600m X 150m. EMX believes that only a small portion of the prospective area has been drill tested, and several untested geophysical and geochemical anomalies suggest ample potential exists for new discoveries on the property.
