Vein quartz deposit.

A short tunnel, presumably developed on a large quartz vein. An examination of the mine workings and dumps found only quartz and country rock - no sulfides or other minerals worth reporting. The mine was probably a gold swindle site.

Coordinates are for Bean Mountain summit as nothing obvious could be seen on the USGS National Map lidar hillshade layers.
