[QUOTE="user 4386, post: 646302, member: 4386"] I realise this is old but XLOOX has it right. We came across this problem when trying to estimate the gold production of each goldfield in a State. We found that the "declared" boundaries often had no clear relationship to the geological distribution of gold. Named goldfields could have recorded tens of million ounces of gold production or a few hundred ounces - you could fit half a dozen of some goldfields into the boundaries of another. Sometimes the entire production was within a single sq km, other times many tens of sq km. I mention this because if you are trying to work out where best to detect, you need to realize that the old "political" boundaries like this are not very helpful. You can do better by simply overlaying old shafts and leads using the states' digital database, overlaying geology and working out which leads are buried under basalt lows fetc - then overlaying "no go" areas for prospecting. And deciding whether you are going to cover everything or just old mine dumps- in the latter case you can extend further over buried leads (placers). Then talk to farmers because in places like Victoria most will be on private land (certainly not all). [/QUOTE]
