HC Deb 24 January 1957 vol 563 c67W
60. Mr. Russell

asked the President of the Board of Trade the extent of deposits of tin, tungsten, lead, zinc, and other nonferrous metallic ores in Britain; and how far are they being worked.

Sir D. Eccles

The extent of these deposits is not precisely known. There are at present two tin mines and about a dozen lead and zinc workings in operation in this country. They produce about 1,000 tons of tin, 6,000 tons of lead and 3,000 tons of zinc a year.
