At a Glance
Perran Moon raised concerns about global tin availability in Westminster Hall. A government minister responded.
Key Requests to Government:
Moon asks the Government to recognise the strategic importance of tin and to develop an investment case for a tin smelter based on UK economic security. He also inquires about the steps the Government will take to strengthen domestic critical minerals supply chains, the progress made in implementing the critical minerals strategy, and the consideration given to supporting domestic processing and refining capacity. The Member invited the Minister to visit the South Crofty tin mine and to focus closely on the tin sector across Cornwall, aligning with the devolution deal.
How the Debate Unfolded
MPs spoke in turn to share their views and ask questions. Here's what each person said:
Lead Contributor
Opened the debate
Perran Moon is concerned about the economic and geopolitical risks associated with the overconcentration of tin processing and supply among a small number of countries. He notes that tin is crucial for modern technologies, yet its supply is highly concentrated, with China alone refining more than half of global tin. He highlights that demand for tin is rapidly expanding, particularly in sectors like electric vehicles and renewable energy, but there is a significant risk of supply shortages by 2035 due to declining ore grades and environmental concerns in producing regions. He also mentions the closure of the South Crofty mine in Cornwall, which could reopen in 2028, potentially producing up to 4,700 tonnes annually. The Member for Falmouth and Camborne emphasised the importance of the Kernow industrial growth fund, which is supporting exploratory mining opportunities in Cornwall, including the work of Cornwall Resources. He highlighted the need for unblocking planning and permitting issues and the critical role of the skills agenda in maximising opportunities in the sector. The Member also stressed the urgent need for exploration of critical minerals beyond tin, tungsten, and lithium, including nickel, cobalt, uranium, and silver, to obtain necessary data.

Anna Gelderd highlighted Cornwall's mining heritage and the potential for the Cornwall Resources Redmoor tungsten and tin project to bring investment and opportunities to South East Cornwall. She emphasised the need for responsible development and environmental protection, noting the strategic importance of tin in the context of growing demand from electronics and clean energy sectors. She also mentioned the current gap in the tin supply chain and the potential for creating processing and manufacturing jobs in the UK. The Member for South East Cornwall highlighted the local benefits of Cornwall Resources' work in tungsten mining and the need to tie the skills agenda in with the devolution deal.

He congratulated the hon. Member for Camborne and Redruth on securing the debate and highlighted the importance of tin in the UK's economy. He noted the investment in the South Crofty mine and the UK Infrastructure Bank's previous investment in Cornish lithium. Davies pointed out the lack of mention of China in the Government's critical minerals strategy and questioned the Government's approach to rising energy costs and the security of supply routes for tin. He also raised concerns about the impact of national insurance rise and the Employment Rights Act 2025 on the industry. The Opposition spokesperson acknowledged the importance of Cornish tin mining and the potential for geothermal energy to drive industrial regeneration.
Jim Shannon

Strangford
Shannon commended the hon. Member for Camborne and Redruth for securing the debate and highlighted the significance of tin availability for businesses in Northern Ireland. He supported Cornish Metals' plans to establish production at the South Crofty mine in Cornwall, which could secure a supply for the west and ensure Northern Ireland has accessible tin at an affordable price, free from EU interference.

Camborne and Redruth
Tin is a critical material for soldering in devices and its global production is highly concentrated, making the market sensitive to disruptions. The UK lacks a comprehensive critical minerals map, and Cornish tin extraction could create jobs and provide a unique primary tin mine in Europe and North America. The speaker questioned the government on steps to meet production targets, strategic stockpiling from electronic waste recovery, due diligence in conflict regions, and partnerships for critical minerals.
Maidenhead
The Liberal Democrat spokesman emphasised the urgent need for exploration of critical minerals, including tin, tungsten, lithium, and others.
Noah Law

St Austell and Newquay
Noah Law thanked his constituency neighbour for securing the debate and focused on the midstream and downstream applications of tin in Cornwall, highlighting the importance of securing the supply chain and the need for Government intervention to address market failures. He mentioned the existence of the Kernow industrial growth fund and the need for Government support in developing supply chain projects, including overcoming challenges such as grid connections and planning barriers. He implored the Minister to bring colleagues from across the Government to secure a tin smelter and address the energy cost issue. The Member for St Austell and Newquay discussed the importance of processing supply chains and the support provided by the Kernow industrial growth fund for exploratory mining opportunities.
Government Response
Blair McDougall
Government Response
Confirmed the Government's recognition of tin's importance to modern economic life, including manufacturing, automotive production, aerospace, clean energy technologies, data centres, telecommunications, and defence. Mentioned the £20 million equity investment in the South Crofty tin project and a £71 million investment into Tungsten West. Highlighted the £25 million critical minerals accelerator to support viable projects, and the introduction of BICS to make energy costs for refining projects more affordable. Discussed the growth minerals list and the Critical Minerals Intelligence Centre's prospectivity report for understanding potential resources. Emphasised the importance of working with international partners to diversify supply and ensure reliable prices and high standards.

About Westminster Hall Debates
Westminster Hall debates are a chance for MPs to raise important issues affecting their constituents and get a response from a government minister. Unlike Prime Minister's Questions, these debates are more in-depth and collaborative. The MP who secured the debate speaks first, other MPs can contribute, and a minister responds with the government's position.
