Copper Fox Metals Commences Drilling Operations at Mineral Mountain Project in Arizona

Strategic Insights

— 2 min read

Copper Fox Metals Inc., a Canadian resource company, has commenced drilling operations at its 100% owned Mineral Mountain porphyry copper project in Arizona. The project is located on a prolific northeast trending porphyry copper belt, approximately 25 kilometers southwest of Rio Tinto and BHP's giant Resolution porphyry copper-molybdenum deposit. The diamond drilling program aims to test at depth the large area of copper-molybdenum mineralization and alteration exposed at surface and the equally large, open-ended positive chargeability body at depth.

Key Takeaways:

  • The Mineral Mountain project covers an area of approximately 4,500 meters long and 2,000 meters wide, with copper mineralization hosted in Laramide age, potassic, propylitic, and phyllic altered porphyritic and non-porphyritic quartz monzonites and biotite granodiorites.
  • The copper mineralization contains enhanced gold concentrations, a characteristic observed in several Laramide age porphyry copper deposits in Arizona.
  • The project exhibits a significant amount of chalcocite, a copper sulfide mineral resulting from weathering/oxidization/supergene cycles.
  • The drilling program is designed to drill test the depth extent of the porphyry style copper-molybdenum mineralization and alteration exposed on surface and determine the cause of the underlying, equally large open-ended chargeability anomaly.
  • The project is located on a northeast trending porphyry copper belt that hosts some of the largest porphyry copper deposits in Arizona, indicating the porphyry potential of the Mineral Mountain project.
  • The drilling program will involve up to 2,000 meters of drilling in four locations, with a flexible design to consider the possibility of extending the length of a drillhole depending on observations in drill core.
  • Elmer B. Stewart, President and CEO of Copper Fox, emphasizes the company's excitement to test this large, high-quality porphyry copper target that exhibits the mineralization, alteration, host rocks, and geophysical signatures typically observed at other porphyry copper deposits in Arizona.

Statistics:

  • The diamond drilling program will test at depth the large area of copper-molybdenum mineralization and alteration exposed at surface and the equally large, open-ended positive chargeability body at depth.
  • The porphyry copper target measures approximately 3,200 meters by 1,200 meters, with a chargeability anomaly of 14mrad.
  • The drilling program aims to drill test the depth extent of the porphyry style copper-molybdenum mineralization and alteration exposed on surface and determine the cause of the underlying, equally large open-ended chargeability anomaly.
  • Copper Fox has designed a flexible drilling program to consider the possibility of extending the length of a drillhole depending on observations in drill core.
  • The project is located on a northeast trending porphyry copper belt that hosts some of the largest porphyry copper deposits in Arizona.
