This small manganese prospect is located between Richford and Berkshire. Follow the gravel road north for one mile from the road intersection three miles east of Berkshire or 2 1/2 miles west of Richford. Just to the east of the road is a small pit and dump. The pit has been filled in with tree stumps.

The minerals found here include hematite (specular), rhodonite, pyrolusite, and calcite.

The surrounding country rock is the Tibbit Hill volcanics and greenstone. This rock is composed mainly of chlorite, albite, and epidote and is a metamorphosed basic volcanic rock. The rhodonite may have originated in a sedimentary or volcanic rock originally rich in manganese and iron which has been metamorphosed to form the rhodonite and hematite. The pyrolusite is the result of recent weathering.
