Adding an assumed grade for PGMs (and silver) to the measly assumed grade of 5g/t gold only seems fair now that we have an assay method for rhodium.
Seems very reasonable.
3.42g/t Rhodium! RHODIUM @ $21,750 USD/Oz
3.42g/t Rh = 39.2g/t Au Equivalent. About 1.3 ounces AuEq / tonne.
Pretty simple maths. An assumed grade of 5g/t gold gives a 26Moz Exploration Target.
If we use an assumed grade of 10g/t AuEq (Au + PGMs) gives a 52Moz Exploration Target
Actually they are drilling much deeper now and that 26Moz was based on drilling to just 50m deep at Tres Estados, so we could add 20% for the much deeper drilling, so let's say 10.2Moz at TE becomes 12Moz which gives us 28Moz. Double it for the 5g/t AuEq PGMs gives 56Moz.
I can't wait to factor in the pilot plant grades when they come. Pretty safe bet that they'll be waaaay north of a measly 10g/t AuEq.
