Strategic Insights

— 2 min read

Diablo Resources Ltd, an Australian mining company, is making significant progress at its Phoenix Copper Project in Utah, USA. The project is located in a proven copper-producing district, with sediment-hosted copper mineralisation along strike from the currently producing Lisbon Valley Copper Mine. The company's CEO, Lyle Thorne, emphasized the national priority of securing domestic supplies of critical minerals, including copper, and the project's strategic location in a similar geological setting.

Key Takeaways:

  • Diablo Resources Ltd has completed a first-pass regional stream sediment sampling program within the Stateline Claim Block, covering 42 drainage points and identifying four priority targets areas.
  • Reconnaissance work completed at Stateline in Q1 2025 along the projected trend of the FDF located a copper mineralised outcrop (Fair Dinkum Prospect) of Dakota and Burro Canyon conglomerates and sandstones.
  • A total of 13 rock grab samples were collected along the outcrop, with significant Cu and Ag results, including peak results to 2.76% Cu and 92 g/t Ag.
  • The company has submitted a drill permit to the Bureau of Land Management covering the Fair Dinkum Prospect and is ongoing drilling at the Trenton and Philadelphia Prospects.
  • Assay drilling results are expected in 3-6 weeks.
  • The Phoenix Copper Project is included as a FAST-41 Transparency Project on the Federal Permitting Dashboard, which will streamline approvals and facilitate a more efficient permitting process.
  • The project proposes to expand open pit mining and beneficiation operations and initiate the extraction of copper through a method of in-situ recovery.
