MCTC Mine


A titanium mine in carbonate-feldspar veins in syenites and phonolite porphyry. Started 1934 and closed 1944. Workings feature 2 open pits. West pit is now Beaver Lake.
Also known as Magnet Cove Titanium Corp. mine.
Deposit: HARD COPY FILE LOCATED AT USBM Eastern Field Operations Center (closed in 1980's). PRIOR STUDY COMPLETED IN 1976 BY K.F. STEELE, UNIV. OF ARKANSAS GRANT G0155021.

Geology: Magnet cove basin is an eroded late cretaceous caldera in which concentric ring dikes were created As a result of repeated cauldron subsidence. The magnet cove deposit is situated on the north side of the middle ring dike.
