Monument record MDR5081 - Brimstone Dyke Mine, Gin Lane, Ashover

SK 344624. Brimstone Dyke Lead Mine, started circa 1756. (1) Lead mine shaft covered by four large slabs of roughly dressed gritstone. Sunk through shale cover into limestone. The shaft was sunk in about 1756 and is one of the few remaining in the parish. The top 15-20ft are ginged (dry-walled) until the shaft enters the limestone, when it becomes square in section (having been round at the top). It is in good condition (in 1973) and its top is covered. There were surface workings as well as a sough driven from the mine to the River Amber which is still traceable. (2) This mine was opened in the early 1750s by Robert Banks Hodgkinson and Isaac Browne, but was a finacial failure and probably did not last the decade, but appears to have been reopened in the early 19th century.
