Jones prospect; Jones Jones and Dodge prospect
A Cu-Pb-Zn-Ag occurrence/mine located 10.1 km (6.3 miles) NNW of Brooksville, along the south shore of Bagaduce Narrows. The USGS MRDS database stated accuracy for this locality is 1,000 meters.
This locality was opened during the Maine Silver Rush of 1880. As was typical of Maine metal mines opened in the time period, the companies were failures and often had fraudulently or mistakenly identified minerals. Many of these mines were supposedly silver mines, but the only "silver" source was low-grade galena. Native silver was never found.
Mineralization is a sulfide deposit (Mineral occurrence model information: Model code: 184; USGS model code: 28a; deposit model name: massive sulfide, kuroko; Mark3 model number: 93). Regional rocks include tuff and tuff agglomerate (rocks of the Castine Formation).
Workings include surface and underground openings comprised of approximately 9 pits or trenches and one shaft, mostly along the shore. A few pits are located approximately 1000 feet S of the shore.
