It was worked out a good few years ago . They then worked at Triton not far away . We used to do test work on samples , in Sydney .Those specimens were at work , all closed down now .
I never went to the mine but I have been passed on the main road a number of times .
My boss , now retired , like me , might have got them . He is not far away , so I will ask him . We are in contact , just had to fix his lawn mower ....
