Despite a lively interest in the topic, technical documents on evaluation and exploration techniques for placer deposits have been in short supply. This book describes the characteristics of all placer deposit types and their source lode deposits. The first few chapters cover interpretation of geology, previous mining methods and associated mining costs and minimum deposit grades. A definitive method and tools for determining proper sample size are covered in Chapter IV. Subsequent chapters provide processing methods and techniques for avoiding errors and evading scams.
