Gold prospecting in Connecticut has a small amount of placer gold, and To finding gold in connecticut can be done in river stream. As is the case in many other New England states, Connecticut does have gold from Alluvial placers, those formed in river or stream sediments.
Alluvial Gold: This is the gold that is deposited through the movement of water. Generally speaking, large deposits of gold are part of the Earth and were put in place many millions of years ago. Over time, these gold deposits were exposed to erosion that led to them being broken up and washed downstream in rivers, creeks and the like. Because gold is far heavier than typical rocks or gravel, it settled in small amounts spread out down the water flow.
