Connecticut holds gold and many other minerals in its fields, forests, rivers, streams and lakes. Connecticut has over 600 abandoned mines and prospects.
Finding Gold in Connecticut isn’t really that hard except you have to look. A lot of the areas holding gold in Connecticut are now off limits for gold prospectors, either because they are on state property although sometimes you can get group permits from DEP to explor in state forests, or they are on private property.
There may be some exceptions to this when it comes to rivers and streams because they are considered to be part of the Waters of the United States as well as Connecticut, so as long as you are not on the bank of the stream you are in the Waters of the United States.
Connecticut has a very rich history as a mining state, 150 years ago my name was a very active industry in Connecticut that could make a well entitled to bear the name the birthplace of the modern mining industry. Something that is now lost to most people as they that wasn't 150 years ago is what mineral deposit lay in their town. If you asked this question today there would be very few people except some Rockhounds would have the foggiest idea what minerals lie under their feet.
Just about any river or stream in the state of Connecticut does have some gold bearing gravel in its bed. Because gold is heavier than any of the other materials that are found in the stream it will migrate down through the gravel to either a layer of clay or bedrock. For the same reason gold is not migrate very far from the banks of the stream so it is rather rare to find much Gold in the middle of the stream.
The best places to look for gold in a stream are along the inside curves, a place where the velocity of the water suddenly slows down such as behind a rock or in the plunge pool beneath a waterfall. Gold is also found where the stream flows over exposed bedrock in cracks that act as a natural riffle. Gold can be extracted from these cracks in the bedrock by using anything that will get the contents of the crack.
There are any number of tools you can use to get gold out of streams; the simplest is gold pan that is nothing other than a shallow pan with wide swooping edges making it look almost like a pie pan. This basic tool will allow a man to process about 1 yd.³ of gravel per day. Man's ingenuity is allowed to devise several different devices for the recovery of gold including rocker boxes, sluice boxes in what are called High Bankers that if designed properly can be used by more than one man processing more than 15 yd.³ of gravel per day.
Although to the author's knowledge there have been very few hard rock gold mines in Connecticut what comes immediately to mind is in the village of Sandy Hook in Newtown.
Even though hard rock gold are pretty scarce in Connecticut there were several other minds that have operated in hard rock probably the most famous one is Ore Hill in Salisbury. This might operated for almost 200 years S. lifetime produced over 7 million tons of iron ore. It was this mine that produced the cast iron for Canon used by George Washington to win the Revolutionary War giving Connecticut the nickname of the Arsenal of the Revolution.
There are several different rock formations in the state a Connecticut that are considered to be metal bearing that could well produce gold. They are scattered all across the state but one of the most likely is just to the west of New Haven called the Maltby Lake Volcanics. This is a Greenstone Belt similar to that found in the Abitibi Gold Province of Canada in Ontario and Quebec.
You can find the Maltby Lake Volcanics and other rock formations on the Internet by
Goggling, “The Bedrock Geological Map of Connecticut.” This map was produced by the Geological and Natural History Survey of Connecticut in 1984. The DEP Store at 79 Elm St. in Hartford also has several other maps and publications that you will find useful in the search for gold or other minerals. One of the handiest maps aside from the bedrock map is the Bedrock Mines of Connecticut by Robert Altamura. Other publications you will find useful are the Aero-Magnetic Maps of Connecticut that are laid out in one large sheet that covers the whole state, or as smaller sheets that only cover one quadrangle each.
As with any hard rock mining ore mineral deposit the easiest ones to find it already been found, but there are still plenty to be found. The other thing you have to remember is less than one mine is developed out of every 300 prospects. An old book on evaluating mineral deposits was titled “Gambler's Ruin,” for very good reasons.
