[QUOTE="Powerhammer, post: 428717, member: 13181"] [i]Hi all[/i] [i]I've cracked open this rock, put it under the microscope and found lots of metal threads some look like copper but others are a white yellow made up of very thin strands like rope. Im going to have it fire assayed but would like to know more about the thread formation and if Copper,gold, silver is deposited this way. The rock looks like an ironstone and is heavily mineralized. On the outside the rock it has a black splattering of dots which I believe is from the heat from its formation, when I use a probe and squashed the black splatter they are soft and smear silver without fracturing. Has anybody seen this formation before and if so what minerials were present.[/i] [i]Thanks[/i] [i]Powerhammer[/i] [i][img]https://www.prospectingaustralia.com/forum/img/member-images/13181/1532856777_img_6273.jpg[/img][/i] [i][img]https://www.prospectingaustralia.com/forum/img/member-images/13181/1532856779_img_6288.jpg[/img] [/i] [/QUOTE]
