Results Of Airborne Geophysical Survey On Sombrero Butte Copper Project


CALGARY - Copper Fox Metals Inc. reported on the results of the high resolution airborne magnetic and radiometric survey on the Sombrero Butte copper project. Sombrero Butte is a Laramide age, exploration stage, porphyry copper project located in the historic Bunker Hill Mining District, approximately three kilometers ("kms") south of the Copper Creek porphyry copper deposit. Historical production from the project is reported to have occurred between 1903 and 1920 from mineralized breccia pipes at the north end of the property with reports of "low-grade ore assaying 3-5% copper and higher-grade mineralization from along open cuts and tunnels assaying 20-33% copper."

The airborne survey mapped the geophysical characteristics related to the distribution and concentrations of magnetic minerals and radioactive elements to provide a geophysical/geochemical framework to compliment the lithology, structure, and alteration data for the project. The principal task of the 3D susceptibility modeling of the magnetics data was to identify new areas of potential copper and gold mineralization.

Highlights: Two K/Th anomalies associated with a positive magnetic susceptibility body located in the footwall of an interpreted west dipping normal fault system have been identified; These K/Th anomalies exhibit coincident: a) N30W trending zones of copper (>500 parts per million ("ppm") and molybdenum (>20ppm) mineralization. b) Mineralized breccia pipes. c) Previously identified chargeability anomalies; The K/Th anomaly at the north end of the property crosses the property boundary to the north; On a regional scale, the geological features of the property hosting the Copper Creek porphyry copper deposit are interpreted to extend to the southeast onto the Sombrero Butte project; and The survey identified several interpreted west dipping interpreted normal faults underlying the central and eastern portion of the property. The centrally located normal fault appears to be the main control on the location of the interpreted porphyry system.

Elmer B. Stewart, President, and CEO, said, "The spatial correlation of the copper-molybdenum mineralization, chargeability and K/Th anomalies, alteration zoning, mineralized breccia pipes to the magnetic susceptibility body suggests a buried porphyry system located to the east of a N30W trending, west dipping normal fault. The 2022 airborne survey increases our geological understanding and confidence in the porphyry potential of the property. Compilation of all exploration data from the project is underway; the results of which will be used to determine next steps to advance the project.”
