Phase 1: Residual to Eluvial to Alluvial Deposits As soon as the gold has eroded from the main lode, we refer to it as residual gold. As long as it doesn't move too long from the original source ( a couple of feet or so), it goes under this name. However, as soon as the gold starts to move from the original source, it's called eluvial gold.
