A interesting slate working in the coppermines valley. It consists of three main levels, with Low Blue being underground, the access level to which is blocked. Middle blue consists of run-in levels, a pit quarry, which has two links to low blue including a shaft at the base. At the top of the quarry there are some chambers reached by another incline. High Blue consists of a pit quarry and a blocked level.
