Go in via the upper entrance if you know the padlock code, enter down the slope, turn first right up some old steps and it is on the right wall. If you drop the shaft you can exit from the bottom.
Or, go in the lower entrance (was secure as of 8.30 pm last night ), follow the main, obvious passage uphill, past a large isolated boulder at the base of a shaft high in the roof, follow the steps up the left wall to a platform (where the upper entrance comes in), follow the next set of steps and go right to find the tall slot leading to the pitch. You can see the hangers from the main path.
