Cheers fellas.Hey Silver,ive been doing a fair amount of research on this creek and ive found that the top end of it is empty when it comes to sapphire or spinel for that matter.So ive checked old geology surveys and I think I may have found something.The erosion of sapphire bearing excarpments seem to be halfway down the creek where it just so happens people have been finding gems for years.Now these escarpments don't feed into the creek itself but after a little more map researching ive discovered a little known creek that runs parallel to the creek I'm in and actually runs into it at a pretty crucial point.So ill finish my hole I started this afternoon which has given me 10 good blue topaz and a half dozen sapphires in my first five sieves.I actually couldn't believe the colour coming out of it and nearly stayed there digging as I had the one last sieve fever.So ill finish that tomorrow and then move up into this little old creekbed and give it heaps.If its all I hope it is then there will be another river added to Tasmanias list by the time ive finished.Ill just have to have my wits about me as it looks like it could be a tiger snake a hotbed.
