Ann: Bramaderos - High grade gold in drilling at new Alba target, page-202

had to remind myself why this would give me a notification.

I think your math is off cus you've entered intervals within intervals within the big interval, thus double counting. That particular calculator needs to have only two levels of measurement - the 'big interval' and discrete intervals within it that don't overlap. So when a company does a Matryoshka doll of intervals you need to select one single inner doll to compare to the biggest doll, so to speak. What I did earlier here is choose a grade that I thought marginally economic, say 1 g/t, then use that as a cutoff across the data set, then figure out the extent of low grade smear. However you need the data to do that with any accuracy, which is why I started whinging about it, haha.
