描述
In this book, Dave McCracken thoroughly covers paystreaks-what they are, how they form, where in the river that you will find them, and how to dredge them up without leaving paying quantities of gold behind. This book, just like McCracken's other mining books, is completely packed with useful information for any gold dredger; but the technology concerning paystreaks, standard sampling procedure, and standard dredging procedure is absolutely vital to each and every gold dredger if he or she wants to get into paying quantities of gold continuously. If you don't do anything else this year to improve your gold dredging skill, buy this book and study it You will not be disappointed!
