Hydrogeochemical prospecting for gold: Groundwater collected from wells, springs, and drill holes may provide clues to the presence of subsurface gold deposits. As groundwater flows through the deposit, minute amounts of gold are leached from the rocks. These can sometimes be detected in groundwater samples collected from wells located down gradient from the deposit.
Gold isn’t being mined commercially in Connecticut to our knowledge, but there are still some small placer deposits that will produce gold for a recreational prospector. Leadmine Brook near Thomaston is one area known for gold. Spruce Brook is another. Both are tributaries to the Naugatuck River.
Prospecting for lode deposits of gold is not the relatively simple task it once was because most outcrops or exposures of mineralized rock have been examined and sampled. Today's prospector must examine not only these exposures, but also broken rock on mine dumps and exposures of mineralized rock in accessible mine workings. Gold, if present, may not be visible in the rock, and detection will

This gold may be still embedded in rock, known as "lode gold", or it may have been deposited in a placer (a natural concentration of gold particles in sand or gravel bars) after weathering from the host rock -- or it may be found in plant tissues, or seawater, or even present in minute quantities in beach sand. (Gold is found in copious amounts on Alaska beaches and even in Oregon.) If your

The gold that these rocks contained has been washed down into creeks to form alluvial (placer) gold deposits. Here, the gold is further concentrated by the action of water. Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be
Gold can be found in very small quantities throughout New Jersey, although not in quantities to attract commercial mining. Recreational gold prospectors can find gold in New Jersey, mostly by panning creeks and rivers that have fine glacial deposits. Gold panning and prospecting in New Jersey.
Gold is also found in conglomerates that are lithified placer deposits. Gold has been reported from a number of places in Wisconsin, but the known deposits are all small and not economically viable.
