Buckhorn Creek is a porphyry copper project located in north-central Arizona’s Castle Creek Mining District, approximately 70 kilometers north of Phoenix. The Project is located within a highly extended belt of rocks that includes the Sheep Mountain porphyry copper-molybdenum deposit located ~9.5 kilometers to the northeast. The target at Buckhorn Creek is an untested porphyry copper system concealed beneath post-mineral cover. Deeper and peripheral structural levels of the system are exposed in basement windows between post-mineral extensional faults. Porphyry-style alteration and mineralization expressed in the basement windows vectors toward the area of post-mineral cover on the property. The Buckhorn Creek project is available for partnership.
The presence of leached-cap and mineralized and altered porphyry clasts with local copper oxide in basal post-mineral conglomerates suggests a proximal source concealed beneath volcanic cover rocks on the property. Felsic porphyry dikes containing quartz-chalcopyrite veins cut the basement rocks adjacent to the post-mineral cover. During a previous partnership on the project, an IP survey yielded a 600m long chargeability anomaly concealed beneath the post-mineral cover rocks, at a depth of approximately 200m. Drill sites have been permitted to test the chargeability anomaly, and project is ready for exploration follow-up.
Note: Deposits of the Castle Creek District provide geologic context for EMX’s Buckhorn Creek project, but this is not necessarily indicative that the project hosts similar mineralization.
