General comments

Subject category Comment text
Deposit 3 RATHER POORLY DEFINED VEINS OR ZONES OF MINERALIZATION 40 TO 50 FT APART ROUGHLY FOLLOWING THE STRIKE AND DIP OF THE CHERT. VEINS ARE OF BRECCIATED CHERT CEMENTED BY SMALL VEINLETS OF DRUSY AND FINE-GRAINED QUARTZ, SOME LAMELLAR. THERE ARE ALSO SMALL SEAMS CROSSING THE CHERT AT RIGHT ANGLES TO STRIKE, CARRYING MOST OF THE PROPERTY'S FREE GOLD
