Core Resources recently completed metallurgical testwork as part of the latest study program for Havilah Resources’ (ASX: HAV) Mutooroo Project, delivering strong copper recoveries and highlighting the project’s robust processing potential.

Located southwest of Broken Hill, Mutooroo is a copper-cobalt-gold project with significant scale and strong smelter alignment. The recent ~$3 million study was sponsored by JX Advanced Metals (JXAM) and included drilling, metallurgical testwork and a mining study.

Key Metallurgical Highlights

Metallurgical testwork, conducted by Core Resources using composite samples from dedicated drillholes, confirmed:

✔ High copper recovery: >91% via conventional flotation
✔ High-grade concentrate: 28–30% Cu, with low deleterious elements
✔ Magnetic separation: Effective in cobalt recovery from pyrrhotite

The flowsheet is flexible, with potential to tailor concentrate products to smelter preferences, whether high-copper, high-sulphur, or high-cobalt.

The ore also proved amenable to low-cost, energy-efficient grinding, further supporting processing viability.

Core’s Role

Core worked closely with JXAM to develop a comprehensive test program that evaluated multiple concentrate streams. Our work confirmed that Mutooroo’s sulphide ore responds well to conventional processing and presents opportunities for product customisation based on market demands.

Looking Ahead

With strong technical results in hand, Havilah and JXAM are now in discussions to proceed with a comprehensive pre-feasibility study (PFS), with work expected to begin in July 2025. Expanding the resource through further drilling will also be a key focus moving forward.

Core Resources is proud to have supported this important milestone for Mutooroo and looks forward to seeing the project advance toward development.
