| Deposit | LITTLE IS KNOWN OF THE CHARACTER OF THE PEGMATITE. BOTH THE COUNTRY ROCK AND PEGMATITE ARE WEATHERED TO A DEPTH OF AT LEAST 12 M (40 FT). AT THE BERRY NO. 2 MINE. IN NO. 3 PROSPECT A 1 FT WIDE QUARTZ VEIN WAS EXPOSED, WITH SHEETS OF MICA OBSERVED ON BOTH SIDES OF THIS VEIN. IN NO. 2 MINE SOFT MICA-BEARING PEGMATITE FORMED THE FLOOR OF THE SHAFT AND MASSIVE QUARTZ BORDERED THE NORTH WALL. FROM THE LITERATURE IT IS UNCLEAR FROM WHICH DEPOSIT THE TANTALITE-COLUMBITE WAS FOUND, BUT IT APPEARS TO BE NO. 1 OR NO. 2 MINE. |
