Greenwood Peak, Arizona

Greenwood Peak is a porphyry Cu-Mo project located ~24 kilometers southwest of the Bagdad mine, in western Arizona and is available for partnership. Porphyry style alteration is exposed over 1 square kilometer and QSP veining and Laramide intrusive rocks display an ENE-WSW orientation, similar to the nearby Bagdad mine.

Mineralization consists of oxidized sulfide-bearing veins. Outcropping "leached capping" contains up to 5-7 vol% stockwork veining with 2-5 vol% oxidized sulfide sites. Laramide intrusions and volcanics are observed in an ENE-WNW belt that transects the Bagdad mine complex and trends towards the Greenwood Peak project area. The target is hypogene mineralization below chalcocite enrichment zone.

Note: The nearby mines and deposits in the region provide context for EMX's Project, but this is not necessarily indicative that the Project hosts similar mineralization, tonnages or grades.



WSW-ENE cross section showing the porphyry system cut and offset by both down-to-the-east and down-to-the-west normal faults. Approximately 25° of southwesterly tilting accompanied the extensional faulting in this area, which results in a porphyry system that plunges steeply off to the NE. Click to Enlarge
Simplified geologic map highlights the contact between Proterozoic basement and post-mineral Quaternary-Tertiary cover. Quartz-sericite-pyrite mineralization has a northeasterly orientation with alteration intensity vectoring toward post-mineral cover. The most intense alteration is offset by both down-to-the-east and down-to-the-west normal faults. Historic drill holes are shown as red circles, and labeled with collar ID, depth to bedrock, and total depth. Click to Enlarge
