Ann: Strong Mineralisation in Manto & Callancocha Structure, page-55

At the risk of being corrected by those better qualified than myself

If we focus just on the mineralised mantos intersected by RDDH-004 the company said

Let's ignore the high grades, imo the average grades are more important when you're looking at a potential resource over such a large area. We think this mantos is approx 2000m x 800m x 15m. So that's about 8 million m³ Assuming a specific gravity of about 4 tonnes per cubic metre that's about 32 million tonnes of ore.

If you enter the above average grades of the zinc, lead & silver into the ***** Casey calculator ( http://www.*****.com/pop_windows/*****rockcalc.html ) you get $US89.61 per tonne - that's about $AUD 113.43 per tonne.

$113.43 x 32 million = $AUD 3.63 Billion. That's without factoring in the veins or the disseminated mineralisation. It also doesn't allow for any Cu or Au that may get thrown into the pot later.

Happy for someone to point out the error in my calculations (I know it assumes that the average grades will be consistent throughout the mantos and it also assumes the mantos is actually as big as we think it is, but even if you were to halve the figures it's still pretty good imo). So @jkb1420 I think you're allowed to get a little bit excited again.
