Previously unrecorded coal mine located in Bilston Wood close to the footpath from the former Path-head Farm (now Bilston Industrial Estate) on the north of the Bilston Burn, to Langhill Farm near Dryden Tower (a 19th century folly), on the south side of the burn.

Examined in August 2010 by Mark Stanford and Jim Salvona. They went in a few metres but retreated due to instability. Mark dug a further 2 m into the mine in September 2010. Derek Pettiglio dug his way into a roomier passage in February 2012 to reach about 25 m into the tunnel on a bearing of 235 degrees to where it was blocked with breakdown. A week later Derek passed this blockage and entered about 40 m of spacious passage with some calcite on the walls. Returning a week later he went 10 m further to where the passage made a sharp left turn on a bearing of 175 degrees. 2 m later the passage closed down to a low arch filled with sand, silt and stones. There was a strong sound of running water beyond. 2 m further was dug out reaching a point where the solid roof ended possibly at the foot of a shaft. The sound of water was ahead and below.
