Mesa Well, Arizona

Mesa Well is a porphyry copper project located on the western flank of the Pinaleño Mountains in southeastern Arizona and is available for partnership. Exposed in the basement outcrops adjacent to the property is a Laramide-aged dike swarm with associated porphyry-style alteration and mineralization. Post-mineral faults identified throughout the project area have dismembered and extended the dike swarm, tilted post-mineral sedimentary rocks to steep angles, and offset the deeper portion of the porphyry system beneath the EMX property along a low-angle fault.

Drilling by EMX intersected porphyry-style alteration and quartz (Cu-Mo) veins beneath the post-mineral cover. The vein density suggests the system is zoning to the north, indicating the focus of the previous drilling was south of the main system. EMX has permitted 20 additional drill sites covering the new target area to provide for a flexible test of the area.
