DRA Global to Deliver Mt Lindsay Scoping Study for Critica

Why It Matters

The study could unlock a major domestic source of critical minerals, reducing reliance on overseas suppliers and supporting Tasmania’s push for sustainable mining. A positive outcome would likely attract investment and accelerate project financing.

Key Takeaways

• DRA Global appointed to conduct Mt Lindsay scoping study
• Project contains >80,000 t of tin and 3.2 Mt of tungsten
• Study will assess low‑impact underground mining versus open‑pit
• Potential to boost Tasmania’s critical minerals supply chain

Pulse Analysis

Tin and tungsten are classified as critical minerals for electronics, renewable energy and defense applications. Global demand for tin, driven by solder and battery technologies, is projected to grow at a steady pace, while tungsten’s high‑temperature strength makes it indispensable for aerospace and tooling. Tasmania’s Mt Lindsay deposit, with more than 80,000 tonnes of tin and 3.2 million tonnes of tungsten trioxide, represents one of the few large, high‑grade sources in the Southern Hemisphere. Securing a reliable supply from such a deposit can help diversify the market away from traditional Asian producers.

DRA Global, a specialist engineering and consulting firm, has been engaged by Critica to produce a scoping study that evaluates a low‑impact underground mining approach. The study will model ore body geometry, ventilation, waste handling and cost structures, comparing them against the original open‑pit concept. By focusing on underground extraction, the project aims to reduce surface disturbance, preserve the region’s sensitive ecosystems, and meet increasingly stringent Australian environmental standards. DRA’s previous work on similar high‑grade, deep‑ore projects provides a strong technical foundation for accurate feasibility assessments.

If the scoping study confirms economic viability, Critica could fast‑track development, positioning itself as a key supplier of tin and tungsten to North American and European manufacturers seeking non‑Chinese sources. The project also promises job creation and infrastructure investment in northwest Tasmania, while aligning with government initiatives to expand domestic critical‑minerals production. Investors will be watching the study’s outcomes closely, as a positive result could unlock significant capital for project financing and boost the company’s market valuation.
