Why UK Tungsten Supply Matters: The Engineering Behind Britain’s £71m Critical Minerals Bet

A mine on the outskirts of Plymouth is becoming part of a much larger conversation about Britain’s industrial resilience. On 25 August 2026, the National Wealth Fund announced an investment of up to £71 million in Tungsten West. The funding is intended to support the restart of the Hemerdon tungsten and tin mine in South Devon and help establish a secure domestic source of a material used across several strategically important industries.

The intervention raises an obvious question: why is the UK tungsten supply important enough to justify Government backing on this scale?

The answer reaches far beyond the mine itself. Tungsten is associated with manufacturing, high-technology supply chains, aerospace, defence, electronics and next-generation energy. That means access to it is not merely a mining concern. It is also an engineering, procurement and industrial-capability issue.

Hemerdon will not make the UK self-sufficient in tungsten, nor will reopening a mine automatically create a complete domestic supply chain. However, the project illustrates why access to critical materials has moved much closer to the centre of manufacturing strategy.
