[QUOTE="Digginholes, post: 434204, member: 2490"] The thing with Vulcan is there are multiple was layers, I have dug complete virgin ground there on the other side of the Forrest and found good sapphire wash but in layers that dont resemble what you see in that hole, my digs went down deep through the brown/black top layer of soil into a grey clay, at th bottom of this clay it turns to gravel with a lot of quarts and other rounded river gravels sitting on an orange layer of decomposing granit, this hole was on an old river channel and produced a lot of colour over 100cts total from a 1x1mtr section the best wash sat in and around some big rounded granite boulders. At sapphire bend there was extensive testing done by Fraser mining co its hard to find a good spot there thats virgin, the big hole appears to be virgin but Im not sure on its quality I think there are much better and easier dig sites there. In some spots you will notice the gravels all similar sized these spots are most likely tailings re deposited after the testing as they used a washplant and jig after wards pushing the material back in, taking only what was larger then 3/8 the big size sieves [/QUOTE]
