Golden Sunrise, Nevada

Golden Sunrise is a Carlin-style disseminated gold project located in northeastern Nevada and is available for partnership. The Golden Sunrise project offers the potential for a district-scale discovery, containing five target areas in a hydrothermal system exposed over 52 square kilometers.

Alteration and mineralization are localized at the stratigraphic contacts between silicliclastic and carbonate units of Devonian to Mississippian age. Extensive concordant and discordant zones of hydrothermal alteration are characterized by jasperoid, de-calcification, dolomitization, and sulfide veining. Anomalous to highly anomalous gold and pathfinder elements (As, Sb, Hg, Tl) are distributed throughout the altered zone and highlighted by rock chip and BLEG sampling. Post-mineral extension has resulted in the structural dismemberment of the hydrothermal system across the range. Where extensional faults juxtapose adjacent stratigraphic units, they conceal prospective stratigraphic contacts beneath approximately 100 meters of structural cover. In addition, the extensional faulting preserves the west-tilted target rocks at shallow depths (see cross section below), and create large untested target areas.

Historic exploration completed on the project in the 1980’s and 1990’s focused primarily on outcropping jasperoid. A new understanding and interpretation of the extensional faulting in the project area provides significant upside to test previously un-explored areas of outcropping alteration and mineralization.

*EMX’s exploration samples were collected and analyzed in accordance with industry best practice standards and guidelines. The samples were submitted to ALS laboratories in Reno, Nevada for sample preparation, and Vancouver, Canada (ISO 9001:2000 and 17025:2005 accredited) for analysis. Gold was analyzed by fire assay with an AAS finish. Multi-element analyses were conducted utilizing four-acid digestion and ICP MS/AES techniques. As standard procedure, the Company conducts routine QA/QC analysis on all assay results, including the systematic utilization of certified reference materials, blanks and duplicates.
