Annual production targets of approximately 170,000 tonnes of zinc and 30,000 tonnes of lead metal equivalent establish the project's scale within global base metals supply chains.

Underground Mining Methodology and Equipment Selection

Modern VMS mining operations typically employ mechanised extraction methods optimised for high-grade, compact ore bodies. The underground mining engineering approach minimises surface disturbance while maximising metal recovery from concentrated geological zones. Equipment selection focuses on automation capabilities and operational efficiency in confined underground environments.

Processing infrastructure requirements for VMS deposits centre on differential flotation circuits designed to separate zinc and lead minerals effectively. The metallurgical approach targets:

• Zinc concentrate production: High-grade specifications meeting international smelter requirements
• Lead concentrate optimisation: Co-product recovery enhancing overall project economics
• Recovery rate maximisation: Advanced flotation chemistry and circuit design
