Surveying Suggests Significant Potential Breccia Pipes & Buried Porphyry Copper System At Sombrero Butte

Surveying Suggests Significant Potential Breccia Pipes & Buried Porphyry Copper System At Sombrero Butte

CALGARY – Copper Fox Metals Inc. and its subsidiary, Desert Fox Copper Inc. reported on the activities including results of the hyperspectral survey for its 100% owned Sombrero Butte copper project. The Sombrero Butte project is located approximately 3 kilometers south of the Copper Creek porphyry copper deposit in the historic Bunker Hill Mining District in Arizona.

The Full Spectrum Hyperspectral Survey covered the entire Sombrero Butte project and collected continuous Visual and Near Infrared (VNIR), Shorth Wave Infrared (SWIR) and Long Wave Infrared (LWIR) data. The survey was completed to map the distribution of alteration patterns exposed in outcrop across the project.

The SWIR anomalies exhibit a strong correlation to known breccias and has identified numerous other anomalous signatures interpreted to represent breccia pipes. Three areas have been identified that exhibit a crude circular pattern of illite-sericite that correlates with previously identified magnetic and radiometric anomalies suggestive of a porphyry system.

The LWIR data identified one zone interpreted to represent argillic alteration, one zone interpreted to represent silica alteration. The anomalous areas outlined by the hyperspectral survey exhibit a strong correlation to the late stage intrusives identified by the 2022 airborne magnetic survey.

The survey identified alteration in the Copper Creek granodiorite, the host rock to target #2 located in the center of the property. Target #2 is characterized by a chargeability/resistivity signature, alteration, porphyry style mineralization and mineralized breccia pipes suggestive of a porphyry copper system. Detailed relogging of drill core from two historical drillholes has been completed, along with sampling for petrographic study and whole rock geochemical analyses.

Elmer B. Stewart, President & CEO, said, “The hyperspectral survey suggests that the phyllic and argillic alteration signatures at Sombrero Butte are more widespread than previously known. These recently identified anomalous areas correlate with airborne magnetic and radiometric anomalies indicative of a porphyry copper system and suggest the presence of a significant number of potential breccia pipes, an indicator of a potential buried porphyry copper system. The relogging program was undertaken to map the intensity and mineralogical changes in these holes as a guide to the possible location of the porphyry center.”
