   A 5m pitch drops onto rubble. The second pitch in a rift can be laddered between boulders or through a tight slot and is a 14m drop into a small chamber. (The boulders above the climber should be removed as the ladder might be removing the support).
At the base, the exit is through a small hole in the left hand wall. This emits a draught through a short series of 1m diameter tubes ending at a sloping 8m pitch into a chamber which is directly under 460. The base of the slope has a possible dig, while up the slope leads to a tight 12m pitch (dropped to a calcite choke) and a well decorated rift about 3m wide, choked both up and down a climb at the end. The draught is lost.

   In 2010, the cave was extended by 74m through a dig at the base of the p8. This leads into the decorated Tolentino Chamber and, after another dig, to Satre's Garden where a loose climb up an aven enters another chamber with a possible dig through to a shaft. A possible dig was also noted below the first 5m pitch: a rift that apparently heads away from the cave.

   There is a probability that sites 999 and 1000 are 460 and 459 respectively (see 2018 summer logbook). This was proved in October 2020 so sites 999 and 1000 had been removed for re-assignment.
