National Wealth Fund to Invest Up to $97M in Tungsten West's Hemerdon Mine to Secure Domestic Critical Mineral Supply
The UK government plans to invest up to $97 million (£71 million) in Tungsten West's (AIM: TUN) Hemerdon tungsten and tin mine in Devon, the company announced. The equity and debt investment comes from the National Wealth Fund (NWF) and is aimed at restarting full production at Hemerdon and developing a secure domestic source of tungsten, a critical mineral essential to high-technology supply chains, aerospace, energy and defence. Hemerdon is one of the largest tungsten deposits in the world, and the investment underscores its strategic importance at a time when the UK and other Western nations seek to reduce dependence on imported critical metals.
Why this matters
State-backed equity and debt investment into a listed AIM company is an unusual capital markets event, signalling the UK government's willingness to deploy National Wealth Fund capital directly into critical minerals plays as a supply-chain security measure. The Hemerdon transaction reflects growing Western anxiety about tungsten import dependency at a moment of heightened geopolitical tension. For AIM-listed mining companies, a government co-investment at this scale could reset market expectations about sovereign risk appetite for domestic extraction assets.
On the Ground
The deal activates capital markets work around the NWF's equity and debt structuring, AIM disclosure obligations, and any shareholder approvals Tungsten West may require. Resources and mining lawyers will be needed for the underlying mine financing, while corporate counsel will manage the listed-company regulatory angles. A trainee would assist with due diligence document review, drafting regulatory announcement checklists, and tracking AIM Rule compliance requirements for a significant transaction.
