Dragon's Tail, Arizona

Dragon’s Tail is a porphyry copper project within the world-class Superior-Globe-Miami Mining District, Arizona.

Surface alteration indicates the presence of a porphyry system beneath post-mineral volcanic cover. Oxidized quartz-sulfide mineralization is observed over ~2.5km in the Apache Group quartzite, which extends along strike across the entire property.

The host rocks at Dragon’s Tail include Proterozoic Apache Group supra-crustal rocks, diabase sills, and Paleozoic carbonates, which are also host to the nearby Resolution Cu deposit. The area is underlain by a regional scale Laramide batholith, which is source to multiple porphyry centers across the district.

Tertiary, post-mineral, normal faulting has tilted Laramide porphyry systems and mineralization in the district ~40° to the east-northeast.

EMX recognizes and is targeting this untested porphyry copper system in a world-class district concealed beneath post-mineral cover.

*Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project.
