Economic Copper Grades

[CaptainM]

These are economic copper grades as long as the  higher grade core is found.   BiG is now on the hunt for the higher grade copper center, while every hole they drilled in the periphery of the system ended in copper mineralization.

As another Cu-Mo copper deposit analog to BIG, if we look at the Chuquicamata copper deposit in Chile (one of world's greatest copper orebody), its average copper grade was around 0.76 %.    Primary sulfides (almost half deposit) were around 0.48 % copper, and lower grade sulfides were 0.3 % copper.  

The most recent Hercules holes returned grades of 0.32%, 0.3%, and 0 45% of copper across hole 8, 11, and 21.  Our first discovery hole 5 returned 0.84% copper grade.

If you take into account that the Hercules holes are from the peripheral lower copper grade Phyllic zone, as per company's NR, this would equal or exceed the copper grades found at Chuquicamata in the primary and lower grade sulfides.  

Anyone that tells you these grades are not economical is being disingenuous and simply doesn't provide with the whole picture.

During the townhall meeting one of the Chrises suggested that the mine would be an underground mine.  I take issue with that comment but some people are running with it.  By underground standards nothing found to date makes the cut. Apparently, some of the smaller porphyry deposits in the USA have been exploited by underground means.  Perhaps Chris was keeping his expectations

Agree with your statement Retiredgeo and would add that hole 5 has the closer to surface supergene (still debatable whether we should call it that until further info comes in) that would be economical to mine underground.

Speaking 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
