Analytical data

Result ASSAYED $14/TON IN GOLD BETWEEN 39 AND 52 FT. DEPTH. 32 IN. THICK QTZ. VEINS ASSAYED $4/TON AT 5 FT. INTERVALS DOWN TO 1150 FT.
Result 16 IN. THICK VEINS AT 1200 FT. ASSAYED $30/TON IN GOLD
Result 12 IN. THICK VEINS ASSAYED $9/TON IN GOLD AT 1250 FT. SOME GOLD REPORTED IN ALL BUT A FEW ASSAYS FROM 500 SAMPLES. STUDIES OF DIAMOND DRILL CORE SUGGEST THERE MAY BE WIDE ZONES OF LOW-GRADE ORE IN GREENSTONE. SOME CONC. ASSAYED AT $40-$80/TON.
