The final stage of the tin mining industry in Cornwall is investigated, focusing on the market environment and the interactions between the Government and local mining interests. In particular, the tax system related to industrial subsidies is considered. Though under favourable market conditions minor recovery of Cornish mining was observed until 1985 by attracting internationally famed mining firms, the industry came to an end with the termination of public funding in the 1990s. In the Government's view this industry remained as a marginal industry until the end.
