Deposit TWO MAIN VEINS CALLED THE DAVIS AND THE DUNKIRK. AT MOUTH OF TUNNEL ON THE NEW ERA CLAIM (DAVIS MINE), ONLY ONE VEIN IS PRESENT. THIS VEIN PERSISTS FOR 1400 FT TO THE NE, WHERE IT SPLITS INTO THE NORTHWESTERN SEGMENT, THE DAVIS VEIN, AND THE SOUTHEASTERN SEGMENT, THE DUNKIRK VEIN. DEPOSIT IS VEIN WHICH CUTS PRECAMBRIAN METAVOLCANIC AND METASEDIMENTARY ROCKS.
