The lower level consists of several small chambers linked by adits and three of these seem to have been worked up to the higher level though it is obvious the slab was not worked out.
A second entrance was created on the lower level when it was re-worked.
Limited surface working and with underground levels between 1901 and 1919. It was briefly worked again in the late 1950’s /early 1960s.
