ADR RESULTS ATOMIC DIELECTRIC RESONANCE SPECTROSCOPY Mr Gordon Stove Dr Simon Richards THE PROBLEM TO FIND A COST EFFICTIVE, RELIABLE, PRECISE AND ACCURATE WAY OF PINPOINTING “PODS” OF HIGH GRADE GOLD AND SULFIDE ORE
CHARTERS TOWERS DEPOSIT STYLE Tonalite host rocks >1000m
THE PROBLEM GEOLOGY 150m
THE PROBLEM TECHNICAL LOCATED IN THE MIDDLE OF A CITY DRILLING (NOISE, CLEARING PADS, LOCATIONS UNAVAILABLE, DEEP DRILL HOLES, COST) TEM & SEM, MAGNETICS, GRAVITY and IP & DHIP (size & depth of gold-bearing pods) TIME AND COST ARE EXCESSIVE 15M/DAY, $130/M, average 500m deep holes, 20 drill holes for 6 positive returns = $1.3 million and over 2 years of drilling.
