The 'new' Kimberley Mine was started from the Road End Level, with a substantial long internal electrically powered incline. Work also began to complete a proposal (that had first been made in the mid-1890s) to drive a level through to the Dubbs Quarries. About of level was completed before the project was shelved in favour of further developing the more significant workings under Honister Crag. In 1932, Dubbs Quarry ceased production largely due to the difficulties and slowness of transporting finished slate.
