[QUOTE="Westaus, post: 290034, member: 2598"] Yes it scratches with the fingernail, it forms into minute little glitter pieces. It does break away if too much pressure it is very soft. It has similar consistency to fish scales average about the size of the 5c piece there were others that were much larger. I cannot say for certain, however it was spread across an area of approx .5km with 1 large open cut mine approx 100mt long. The second was cut into the side of a rise and was about more circular. I think was more old timers (early 1900's), it was not as clean? The newer open cut would have been machinery for sure I think around 1970's-80's? In this cut I could see older greenstone flows, plus some extremely hard granite like rock. I believe the limonite could have been in this area. What we don't know is what they actually mined? As this material is not there! This material seemed to be waste and not wanted as there was too much of it left behind. Less than 3km as the crow flies is a known gold mine and gold deposits. I will look over the geo in the area to see if I can get more info as well. Is there a burn/flame test? Thanks for the help so far. [/QUOTE]
