Mining Stock Daily Arizona Sonoran's George Ogilvie Breaks Down today's PFS for the Cactus Project
Oct 20, 2025
George Ogilvie, CEO of Arizona Sonoran Copper, dives deep into the Cactus Project's preliminary feasibility study. He highlights the project’s ambitious goal of producing 103,000 tonnes of copper cathodes annually, which could position it as the third-largest producer in the U.S. Ogilvie discusses the project's impressive economics and necessary adjustments from earlier studies. He also explores innovative processing technologies, the effects of inflation on capital costs, and potential future developments in sulfide production.

Episode notes
Simplified Focus On Leachable Material
- The PFS focuses solely on oxide and transitional material and removes primary sulfides to simplify recoveries and improve clarity.
- Cactus will be a heap-leach/SX-EW open-pit producing most value from Park Salier in the first 16 years.
Newton Tests Could Add Major Upside
- Newton Technology column tests are underway and could produce integrated PFS results by mid-next year if recoveries are positive.
- If Newton's process lifts NPV by ≥20%, they may earn up to 40% of the asset under agreed economics.
Staged Plant Build To Match Ore Profile
- The plant will start at 70,000 tpa cathode and expand to 140,000 tpa after year three to optimize production and tank-house sizing.
- Variable yearly tonnage allows production to drop in high-grade years to better utilize the SX-EW plant.
