Future drilling needs to be upslope and above the blanket in order to determine the full thickness and size of the blanket, which currently grades 0.4-0.6% Copper and 0.15g/t Gold; Primary copper grades are in the 0.3-0.35%+ Cu.
The better grade, potassically altered rocks have not been penetrated by historical drilling. Total tonnage target ranges from 250-500 million tonnes of 0.3-0.5% Cu.
Forte ranks this investment in the same class as Constancia and Zafranal except Don Gregorio contains significant gold mineralization ~ 0.15 g/t Au. Shallow historical drilling <100m ended in copper mineralization and suggest potential for a larger hypogene mineralization at depth.
