Yes thats correct.
I was invited into the project just after the discovery of the horse gin.
I did do a solo dig on one fall, that is the one completely cleared but I think that something was put in eventually for safety to prevent stuff coming down on explorers. All the others are mainly done by the Lawsons.
The awkward drum was put in cut as it would not go in as a whole, it was not a good job and always presented difficulties.
