Holmbush, Redmoor, Kelly Bray where usually worked in conjunction. The small mines of West Holmbush, East Holmsbush (Lady Beam), and South Kelly Bray were occasionally included.

The mine is quite old and was probably at work in the early 1600's, possibly mostly on the lead lode, and again in the late 1700's. From about the late 1830's the amalgamation of the mines may have started under various names to the final closure in 1892.
Holmbush mine developed five ENE-WSW copper-tin lodes of which only Holmbush and Flopjack was developed to any depth. A N-S lead lode was also worked. Where the lead lode intersects the E-W lodes it displaces them 15mts north on the east side. The lead lode was worked by levels driven north and south from the other two E-W lodes lodes between the 90 and 132 fathom levels. The two E-W lodes about 185mts apart where developed by a number of shafts to a depth of 390 mts.
The dumps were worked in 1919-21

There is a dump beside the Kelly Bray to Stoke Climsland road where the 2 engine houses have been partly restored and made safe. This dump has been partly cleared on the field side. Back a little towards Kelly Bray a small unmade track leads down into the valley. Beside this is another dump which has been almost completely cleared. Along the valley floor there is a very substantial dump which does not appear to have been touched by the reworking carried out in the early 1920s.
The grid reference marks the engine house ruin at Hitchins Shaft.
