RE:Economic Copper GradesSpeaking of economic grades, as per today's video from Crescat Capitol and Quinton Hennigh, our recently released hole 11 and 21 carry a copper equivalent grade of 0.53 and 0 55 % (equivalent grade takes into account the other metals that were found in the core). In the video Quinton explains how there is a big porphyry in Bingham Canyon Utah that has an overall copper equivalent grade of 0.56 % that was economical and made money.
To be sure, there are many other factors that need to be taken into account whether a deposit is economical or not.
