[QUOTE="Colb20173, post: 646971, member: 22592"] Hi Folks. OK, so it's not the biggest haul you'll ever see but with the magic of microscopy and some shaky photos (cell phone camera held over the microscope eye piece) they at least look a bit more impressive. About 50 micro pieces found in total from about the same number of pans. Nothing larger than 1mm.No point in weighing this 'haul' (I'd guess it'd be about 0.01g in total) but it is the first gold I've ever found and I guess you've got to start somewhere! :) In this instance it was close to the surface at the head of a gravel deposit on an inside bend. Removing the top 20cm of gravel revealed a thin layer of silt that had formed on top of the main gravel deposit (which is at least 2m+ deep at least so no hope of finding the bed rock). Looks like a recent flood had deposited the fine gold on top of the silt layer. Washed out of the bank at that spot perhaps? No gold found below the silt layer. [/QUOTE]
