What are Alluvial Deposits?

Alluvial deposits are the natural concentration of heavy minerals caused by the effect of gravity on moving particles. Nature various actions known as weathering can and did dislodge gold from its hard rock containment. Once the gold is liberated it migrates by gravity and water flow into larger or subsidiary streams. The net effect of this show migration into streams is concentration of the gold into sometimes valuable gold ore bodies.

The presences of gold nuggets suggest that the occurrence is close to the primary source. The finer the gold the further the occurrence might be from the source. The more rounded the gold particles the stronger the suggestion that the gold has travelled further.

Manica has a distribution of particles size with high frequency of nuggets which is a good sign for primary hard rock exploration.
