A 10m entrance shaft leads to a further descent in boulders for 20m to reach the top of a 20 to 30m shaft. There are dangerous boulders at the top and the rift walls have been opened out to allow access. During this work, one of the drill batteries was dropped down the pitch. A smoke connection to the Orillón system meant it was not pushed, given the unsafe nature of the pitch - "the chances of getting crushed are quite high."
