Kodiak Reports Positive Results From Metallurgical Testwork on the MPD Project

Key Takeaways

• Rougher flotation recoveries reached 91% Cu, 81% Au at 150 µm grind
• First locked‑cycle test confirmed stable 78.7% Cu recovery
• Gold partly free‑milling; gravity recovery could boost Au recovery
• Coarser grind reduces energy use, lowering capital and operating costs

Pulse Analysis

Metallurgical testing is the linchpin that turns mineralized rock into a viable mine plan, and Kodiak’s latest results provide a clear signal that the MPD porphyry deposit is amenable to a traditional sulphide flotation circuit. By achieving rougher recoveries above 90% for copper and over 80% for gold at a P80 of 150 µm, the company demonstrates that the ore can be liberated with a grind size common to industry practice, eliminating the need for ultra‑fine grinding that drives up power consumption and equipment costs.

The shift to a coarser grind size is more than a technical tweak; it translates directly into economic upside. A larger P80 reduces comminution energy by an estimated 20‑30%, which can shave millions of dollars from both capital expenditures and ongoing operating budgets. For a project in the infrastructure‑rich Quesnel Terrane, these savings improve the projected net‑present value and make the project more attractive to equity partners and lenders seeking lower risk profiles.

Equally important is the discovery that a portion of the gold occurs as free‑milling particles, opening the door for gravity‑based recovery methods to complement flotation. Integrating gravity circuits could lift overall gold recovery beyond the 60% achieved in the locked‑cycle test, enhancing concentrate grade and revenue potential. As Kodiak moves toward a maiden resource estimate and further variability testing, these metallurgical insights position MPD as a strong candidate for a world‑class copper‑gold mine, aligning with broader industry trends toward cost‑efficient, high‑recovery processing designs.
