Lomitas Negras, Arizona
The Lomitas Negras property is ringed by Laramide-age intrusive rocks and porphyry copper/skarn deposits that include San Manuel-Kalamazoo (~20 kilometers north), Copper Creek (~25 kilometers northeast), and Oracle Ridge (~10 kilometers southwest). Nearby outcrops exhibit alteration and anomalous base metal mineralization that characteristically occurs on the margins of porphyry copper systems. EMX’s recognition of the altered outcrops, combined with a new interpretation of the extensional structural setting of the area, led to the identification of concealed porphyry copper targets beneath the post-mineralization pediment cover at Lomitas Negras.
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.
