There's also gold to be found on the Barron if you can find a good spot. I like to play on Google Earth and look for good looking bends where there is plenty of exposed bedrock and of course a spot that's accessible without too much leg work. It can take some time/test pans to find where the "gold line" runs at any given section on the Barron as it's a big river especially during flood but you'll learn to look for the right signs to get you on the gold quicker. Not all sections will win you gold though, so be prepared to come home empty handed some days which is perfectly normal. Cross that spot off the map and look for the next. Just be thorough in testing each spot before disregarding it completely as often it'll be there, just not exactly where you might expect (large catchment rivers can be quite difficult to read compared to small-mid sized creeks). Helps to use a detector, doesn't need to be particularly good at finding gold, but to find where bits of iron, lead, etc, are accumulating. Good chance where you find numerous bits of trashy metal dropping, you'll also find some gold under it all -- just make sure to take a pan though as most the gold will be undetectable.
