My choice out of books would be "Fists full of Gold" by Chris Ralph, although based on US prospecting I've applied a lot of his ideas that have paid off, he covers everything from sluicing, detecting, dry blowing, and where to/ how to find gold.
Outside of that mate your on the right forum for top info from seasoned veterans like Loamer, Wal, Redfin, (no reference to age)just to name a few, chuck in Goldigga@, Puddler Bill, ect, ect, and don't forget the geology fellows with Metamorphic, and the list goes on.
It's like a book that answers your questions while your reading :lol:
