[QUOTE="wbvs58, post: 1630893, member: 16453"] Red they were mining in my place from the 1870's up until early 1990's, mostly alluvial tin. A lot of small scale pick and shovel but also some bigger companies with dredges. We back onto the NSW border so on the watershed (rain on our place drains into the Murray Darling system, NSW side drains to the coast via the Clarence river). The alluvial tin would have originated from the rock along the border so there has also been a bit of deep mining done looking for the lode of tin. We have one hole up the back 6'x6'x 65' deep dug by hand at the rate of 1' per week through the rock in 1874. We have another shaft that has a bit of underground work that I believe they got a bit of wolfram (tungstun) out of but I think that was post war when modern alloy metals were being developed. With the drilling they found Tin, molybdenin, tungstun and a 4th one I can never remember. They were looking for gold but did not find anything significant. I spoke to a geologist who was consulting for a big mining company that was interested in buying the mining rights from the exploration company but in his opinion the minerals were in too narrow veins to be a viable proposition to extract. He said that is not to say that in the future it may be viable if the metal prices continued to go up. I am sure that the type of mining that has been done here did not use any chemicals for extraction. It has been left in a bit of a mess, open cut areas from the most recent just left. Areas that look like a WW1 battlefield from the pick and shovel miners plus old dredge holes. [/QUOTE]
