[QUOTE="user 4386, post: 663247, member: 4386"] Ha! No, I understand what you are doing - I did not realise that you are focusing on a specific area and thought you were doing it on a regional scale. But if you are focusing just on one or two goldfields it makes absolute sense. However don't forget to overlay no-go areas, private land etc (there is quite a bit around Wedderburn and Rheola). You will find that potential areas that you can go without permission are quite limited (but I find a lot of property owners are OK simply because you ask). Again, mine depth is a bit irrelevant, That is more a measure of tionnes than grade - most detectorists want coarse gold and nuggets and that is quite different to tonnage - workings on some reefs that have good nuggets in soil only go down a few metres. Yes, I use hard-rock mines on the min eral occurrence layer (an attribute) first but then register old maps and trace missing reefs (50% are missing in some areas but not a lot) - the Geovic data misses a lot of reefs. I have actually provided shaft info to Geovic myself - mining companies tend to map them as they explore and Geovic adds them as the data comes in - it is not all historical. Also shafts can be some distance from outcrop positions once you get down to detail ( usually not more than a couple of hundred meters) - you do not sink your deep shafts through the middle of your quartz reef or your mine becomes unstable once you remove the quartz reef. But for most purposes the shafts are quick and useful. Uh...no :rolleyes: Good luck. [/QUOTE]
