It is a pleasure to serve under your chairship, Mrs Barker. It is also a pleasure to respond to my hon. Friend the Member for Camborne and Redruth (Perran Moon) and to congratulate him on securing this debate. It is a further pleasure to be taken back, at least momentarily, to my summer holiday in the constituency of my hon. Friend the Member for St Austell and Newquay (Noah Law). I will not say where I would rather be at this particular moment. Scientists have said that the shortest scientifically measurable period of time is 247 zeptoseconds, but I can confirm that my own research has found an even shorter measurable time than that, which is the period between someone being appointed the Minister for critical minerals and all the Labour MPs from Cornwall contacting them to ask for meetings and conversations about the potential for critical minerals in that part of the world. Perhaps appropriately for a debate on mining, they are Stakhanovian in their work effort on this issue. This debate on global tin availability is timely, as has been said. It is not always the mineral that attracts the big headlines, but to respond to the first request of my hon. Friend the Member for Camborne and Redruth, I confirm that the Government absolutely recognise that tin is central and fundamental to modern economic life. It is the solder that connects circuit boards, semiconductors, data infrastructure, automotive electrics and of course defence technologies. When global tin supply is tight, the impact can be felt far beyond mining markets, in manufacturing costs, supply chain resilience, investment decisions and, ultimately, the UK’s ability to deliver growth, energy security and national security. My hon. Friend’s constituency is absolutely central to that discussion and to meeting those challenges. It is home to significant tin deposits, including the South Crofty tin mine, which has a high-grade tin resource and the potential to re-establish meaningful primary tin production in the UK. That matters not only for Cornwall’s proud mining heritage, which I was going to say goes back to the bronze age, but given that tin is one of the constituent parts of bronze, perhaps it predates the bronze age. Cornwall is the tin isles mentioned by Herodotus. As has been said, however, the future of tin mining is of much more immediate importance, and a source of excitement. The question before us is not simply whether we can mine more tin again, but how a secure, responsible and diverse tin supply can support jobs, industrial competitiveness, clean energy deployment and economic resilience.
