new copper discovery at serra verde project, page-51

My bet on the current section is that we are on to some sort of en echelon vein system within an east-dipping fault zone, and we also seem to be in the primary ore, not secondary chalcocite, judging by all the sulphide mineral in those pictures. So, we should not be talking about a higher grade cap at this stage, since we don't have evidence for it. En echelon vein systems are a bit different to a typical bit of continuous vein ore. That is, to determine where it extends, you need to join up the tips of each intersection and extend those bottom and top lines to make an envelope.....if you do that, it says that more ore might be found west of ASVD-03 (might even subcrop?), and their ASVD-21 hole should indeed be a good test for more ore. It also allows us not to be disappointed in there being no ore below the ASVD-05 intercept.
