Red Top, Arizona

Red Top is a porphyry copper project in the Superior District of central Arizona. EMX has recognized an extensive zone of intense alteration, ferricretes, and gossan developed eight kilometers north-northwest of the Resolution deposit. 

Porphyry alteration is exposed across a broad area, with locally intense alteration associated with anomalous base metal and molybdenum mineralization. Nearby, post-mineral units are tilted ~30-45º east, indicating an underlying porphyry system is also likely tilted, with the mineralized portion of the system concealed beneath less-altered rocks on the surface. The target is a plunging porphyry copper system concealed beneath weakly altered wall rock on EMX’s property.

The project is available for partnership.

Note: The nearby mines and deposits in the region provide context for EMX’s Project, which occurs in a similar geologic setting, but this is not necessarily indicative that the project hosts similar mineralization.

Sericitically altered schist cross cut by oxidized quartz-sulfide veins. Oxidized vein surfaces contain anomalous Cu, Mo, Pb, Zn. Commonly, vein densities are 1-5 vol% and locally > 10vol%. Click to Enlarge
