This book thoroughly covers pay-streaks -- what they are, how they form and how to dredge them up without leaving paying quantities of gold behind. Just like Dave McCracken's other books on gold prospecting, this one is fully packed with useful information that every gold dredger can use, but the technology concerning pay-streaks and standard sampling & dredging procedures is absolutely vital to each and every dredger if you want to locate and develop high-grade gold on a continuous basis.If you do not do anything else this year to improve your gold dredging skills, buy this book and study it well. You will not be disappointed!
