Silver ores kept the district alive until around 1880. About 1883, gold-bearing ores were found, but the gold could not be separated from the rock. Disappointed, prospectors again left the district. Then, in 1889, these ores were rediscovered and the gold successfully recovered using the newly developed cyanide leaching process.

Welcome to the Maine Geological Survey. Gold in Maine. Gold occurs in several geologic environments in Maine: in bedrock, in sediments that were eroded from bedrock by glaciers, and in stream deposits derived from either of these sources.
Late 15th and early 16th century mining techniques, De re metallica Bronze age gold objects are plentiful, especially in Ireland and Spain, and there are several well known possible sources. Romans used hydraulic mining methods, such as hushing and ground sluicing on a large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas.
