Residual Placers: An Often Overlooked Gold Source

Successful Detecting Requires Attention to Detail—Part I

Prospecting Underground: Use Caution


In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
