CCU is good comparison

For example CCU indicated and inferred resource (Ag only) as at resource upgrade

Indicated
16MT @ 58g/t for 928Mg or 30M Oz
Inferred
14MT @ 46g/t for 644Mg or 20M Oz

Total resource = 50M Oz

(using Troy Oz - approx 31.1g)

Now if we substitute in a higher grade that we would reasonably expect from IVR with the same tonnage of resource for an theoretical JORC

16MT @ 125g/t for 2000Mg or 64.3M Oz
and
14MT @ 95g/t for 1330Mg or 42.8M Oz

Total resource = 107.1 M Oz
not including lead, copper & gold if any

assuming 1. that IVR have the tonnage and 2. that IVR will have a much higher grade resource..

of course this is a broad comparison and does not suggest that this is what IVR jorc will be.. but i think that it paints a picture
