MINERAL RESOURCES 81 Associated with the quartz lenses are bodies of mineralizedschist, carrying pay values in gold, and lying between or near thelenses have been found schist ores of very high grade, but with theusual intervals of lower grade material in the same ore. Until recently the development of these ores has been carriedon on the high grade lenses only and the low grade ores practicallyignored, owing to lack of facilities for treating them profitably, but(luring the past year a cross-cut has been run west from the loweror 400 level and the occurrence condition of these low grade oresdetermined. This cross-cut is 180 feet long and cut through aseries of quartz lenses and schist leads, which were found to varyin value from a trace to $50 per ton gold, but the free conditionremained unchanged as in the other parts of the mine. Tests onthis work showed an average mill value of $6 per ton the wholelength o
