Employed at the Sons of Gwalia Gold Mine, the deceased was struck on the head by a drill dropped from higher up in the stope. A man named Martin Epis found the deceased in the stope apparently severely injured. He at once called for assistance and a miner named Andy Delia (who was working with him) and others carried the victim down the shoot to the level. Castellanelli was immediately taken to the hospital and Dr Cameron, who was in attendance, held out no hope of his recovery owing to the serious nature of the injuries to the skull, which was badly fractured. The deceased lingered on till about 9 o'clock in the evening and then passed away.
It was the verdict of the Coroner that Pietro Castellanelli died from a fractured skull from a drill accidentally dropped down the mine shaft by one Martin Epis. He left an estate valued at £329 3s. 5d to Guiseppi Fausto Castellanelli. It appeared the deceased had only one relative in the state but it is not known what relationship they had to each other.
