THE PROBLEM

TO FIND A COST EFFICTIVE, RELIABLE, PRECISE AND ACCURATE WAY OF PINPOINTING “PODS” OF HIGH GRADE GOLD AND SULFIDE ORE

SLIDE 4

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.
