Located South of US Highway 378 between Lincolnton and Washington.

Graves Mountain was first described in 1859 by Professor C. U. Shepard. In the early 1900s, George F. Kunz purchased the upper portion of Graves Mountain, where he allowed friends to work the area for specimens. Dr. Paul Bennett purchased the mountains in 1961 and began commercial kyanite mining in 1963. The operation was later purchased and expanded by Combustion Engineering Inc. in 1965. During Combustion’s ownership, the kyanite mined from Graves Mountain accounted for over half of the kyanite consumed annually in the United States. The property changed hands once more in 1984, when it was sold to the Pasco Mining Company, which continued operations until November 1st, 1986, when ownership reverted to Combustion Engineering Inc. After this change in ownership, mining never resumed.

Graves Mountain is currently accessible and open to mineral collecting, but only with the owner's permission. There are 2 pits accessible for collecting: the main (west) pit and the east pit. The main pit is where various minerals, such as rutile, kyanite, and lazulite can be found. The east pit is where specimens of iridescent goethite and pyrophyllite can be found.

The geology of the Graves Mountains consists of interbedded kyanite quartzite and sericite schist that has been intruded by hydrothermal solutions, introducing quartz veins.
