Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Description: Exploration By Dmea Revealed That The Mafic Intrusive Where The Sulfide Mineralization Occurs Is Pipelike In Form, Consisting Of Gabbro And Norite. The Pipe Plunges Approximately 30 Degrees E. Along A Contact Between Quartz-Sericite Schists And Overlying Graphitic Pyhillite. It Has A Maximum Diameter Of 60-200 Feet And Has Been Explored For 900 Feet Downdip.
