By reviving domestic production at South Crofty, we're not only creating over 300 direct jobs but also supporting many more across local supply chains and regional businesses.

Rachel Reeves, Chancellor of the Exchequer, commented: "Like in every part of the UK, I am determined to unlock growth that creates jobs and puts more money in Cornish people's pockets. Our investment to revive Cornwall's proud tin mining industry and the thousands of jobs it will create for years to come is one way we are renewing the county."
