Hi Tractor,
It's mostly hard rock mining around Bundy, grams to the tonne..you might find some colour panning in creeks.
You will need to get private permissions if you want to look around, the nearest GPA is Deep Ck in Gympie.
Don't get caught fence jumping as you may find yourself getting chased off by an angry farmer with a shottie.
The nearest nuggety ground is around Gladstone, private permissions required also...
