Deposit Discovery Year: 1880'S
Deposit DEPOSITS CONSIST OF LARGE, IRREGULAR TO ROUGHLY TABULAR BODIES OF TACTITE COMPOSED CHIEFLY OF MAGNETITE, GARNET AND PYROXENE. TACTITE INCLUDES THREE DISTINCT VARIETIES, A DARK-COLORED MAGNETITE-FLUORITE-HELVITE RIBBON ROCK, A LIGHTER-COLORED SILICATE-RICH RIBBON ROCK, AND A FLUORITE-RICH MASSIVE TACTITE. THE PROPERTY CONSISTS OF ONE PATENTED CLAIM, 6 CLAIMS ON STATE LAND AND 27 UNPATENTED CLAIMS.
