No recorded repairs
Redburn mine, less than 1 km west of the village of Rookhope, is a relatively recent Fluorite mine begun in 1964 and eventually closed in 1981. Rich deposits of Fluorite were extracted for use mainly as a flux to supply the local steel industry and although most collectors of British minerals have the odd fluorite specimen from here, it is for its jackstraw Cerussite it is famous. This is a fine miniature of opaque, creamy straw to pale barley fawn crystals with areas of pale apricot staining. The acicular crystals attain up to almost 5 cm in length and form a tightly intergrown cluster of mainly sub-parallel jackstraw crystals.
