| Deposit | MONZONITE ENGULFS SEVERAL PENDANTS OF METAMORPHIC ROCKS (SLATE, SCHIST, TACTITE) WHICH STRIKE N70W, DIP 60-75 NE. EXPOSURES ARE POOR DUE TO SURFACE COVER. 3 SMALL PENDANTS ARE KNOWN. THE NORTHERN ONE IS ABOUT 13 FT WIDE AND CONSISTS OF BIOTITE SCHIST AND A BED OF TACTITE 4.5 FT WIDE CONTAINING SOME SCHEELITE. A SECOND PENDANT ABOUT 450 FT TO THE SOUTH IS 18 FT WIDE AND CONSISTS OF TACTITE INTERBEDDED WITH SCHIST. IT IS EXPOSED FOR A STRIKE LENGTH OF 50 FT BUT IS CUT BY GRANITE AT 2 PLACES. A THIRD PENDANT IS 13 FT WIDE AND IS APPROXIMATELY ON STRIKE WITH THE SECOND PENDANT BUT IS SEPARATED FROM IT BY 200 FT OF GRANITE. THE ORE EXPOSED IN THESE PENDANTS CONTAINS 0.5 TO 0.75 % WO3. |
