London-based Strategic Minerals PLC (SML) has announced a technological breakthrough at its flagship Redmoor project. A massive spike in tungsten recovery rates promises to redraw the mining economics of the historic Tamar Valley and catapults the company into the premier league of critical mineral suppliers.
Efficiency as a Capitalization Driver
In the mining sector, the difference between a "prospective project" and a "cash cow" is measured in recovery percentages. Fresh metallurgical study results from subsidiary Cornwall Resources Ltd show that the recovery rate for tungsten trioxide (WO3) has surged to 85.8%.
For context: in the 2020 scoping study, this figure stood at 72.0%. A relative uplift of 19.2% means that for the same extraction costs, the company will produce nearly a fifth more saleable product. In an era of volatile commodity markets, this kind of margin provides a powerful "safety cushion" for investors.
The Silver Surprise: A New Multimetal Dimension
The report’s major revelation was the official confirmation of silver recovery. The study proved that silver can be effectively recovered within the copper circuit at a rate of 58.7%, with grades of 270 g/t in the copper concentrate.
The inclusion of a precious metal transforms Redmoor into a high-value polymetallic hub. Silver acts as a "smelter credit," directly offsetting operational costs and boosting the project's overall Net Present Value (NPV).
Andrievskii Verdict: A Stake in British Sovereignty
Strategic Minerals PLC is transforming Cornwall’s historic mines into a high-tech asset of global strategic importance. The technological upgrade to 85.8% tungsten recovery, coupled with confirmed silver reserves, creates a massive financial lever.
Technological Supremacy: While the average recovery rate at profitable tungsten mines worldwide typically fluctuates between 65–70%, Redmoor has achieved 85.8%. This means Strategic Minerals extracts 22–32% more saleable metal from the same volume of ore than the average global competitor. Effectively, the company has slashed unproductive metal loss by nearly half, placing the project among the most efficient tungsten deposits on the planet.
AISC & EBITDA Economics: This ultra-efficiency radically lowers the All-In Sustaining Cost (AISC). While competitors struggle with cost inflation, Redmoor expands its margins through technological leverage and "silver credits" that subsidize tungsten production. Preliminary estimates suggest that a 20% recovery boost, combined with current tungsten prices, could increase the project’s projected EBITDA by 25–30% compared to 2020 models.
For investors, this is a clear signal: the project has reached a new level of profitability, becoming one of the most resilient and high-margin tungsten assets in the West. Market attention is now locked on the updated Mineral Resource Estimate (MRE) due in early 2026—the milestone that will reveal the true scale of the company’s valuation explosion.
