Contact Group

The Contact Group is a copper, tungsten, molybdenum, gold, and silver mine located in Wallowa county, Oregon.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Comment (Production): EARLY 1900'S

Comment (Development): ECON.COM: NO MATERIAL OF MINABLE GRADE WAS FOUND.

Comment (Workings): HAROLD AHALT OF LOSTINE IS NOW PROSPECTING. 225 FT ADIT 575 DEG E IN QUARTZ DIORITE & OPENINESS IN ADJACENT CRYSTALLINE LIMESTONE . A DRIFT NEAR THE CONTACT BETWEEN LIMESTONE AND APLITE HAS BEEN DRIVEN S75E FOR 75 FT.EARLY 1900'S

Comment (Geology): GEOL.DESC: AT CONTACT BETWEEN QUARTZ DIORITE AND A MARBLE BED IN THE HURWOL FM, N 55 DEG W, DIP 71 DEG E.

Comment (Deposit): IT IS MORE PROBABLE THAT THE MINERALIZATION IS DUE TO THE ACIDIC RATHER THAN THE BASIC INTRUSIONS.
