HC Deb 11 May 1953 vol 515 c61W
61. Sir L. Plummer

asked the Minister of Materials what results have been obtained from the attempts begun in 1949 to mine potash on the North-East Coast.

Sir A. Salter

Exploratory work has now been completed and the firms concerned are considering the mining engineers' reports. I have had some discussion with these firms, but it is clear that the economic and technical problems involved require considerable study.
