Approach

In the vicinity of the Aurelia - Esperanza mine adits

Entrance

1m high by 2m high adit

Description

straight adit with side passage almost immediately on right that is closed with deads straight ahead but slopes back underneath the entrance adit, potentially dropping into mined vein. Not explored and rope advised.

Straight on continues for around 50+m to a T junction. Left ends after around another 50m, whilst right gains a timbered floor section with a drop down. This can be crossed on the right side, and the passage continues following a mined vein to end in a tight natural rift. There may have been a potential lead on right side but blocked with mine spoil.

Returning to the hole, the pitch descends past a series of platforms, the bottom sections of which still have wooden access ladders in place (very rotten ladders that is!). Right direction (mirroring passages above) very quickly leads to another drop, and mined passage also continues, but floor is very clearly mud-covered timbers, and this was not explored any further. (This most likely continues to connection with T125)

Left continues in typical mine fashion for about 20m to reach intersect a natural shaft. This can be crossed on a ledge but soon ends. Shaft is around 8m drop, followed by another 6m drop, to miners spoil and no way on.
