What Is the Average Grade of Producing Gold Mines,

Hi Dai Uy, because at $1781.30 per oz. of Gold @ 2.33 ozs. per Lb. of ore concentrate & approx. $636 per oz. of Pd per Lb. of ore concentrate spells $8,300,860 per ton of this type of ore for gold; approx. $839,520 per ton of this type of ore for Pd, plus the Pt 1/5 to 1/4 oz per Lb.Making the grade: understanding exploration results,,GOLD: It is usually reported in grams per tonne (or g/t), although sometimes, in the US, it is in oz/ton. A gram of gold is worth about $25, so 2 grams or better would be viewed as high-grade for,How to Evaluate a Gold Deposit - Comparing Two Deposits,,Oct 11, 2011· This mining and processing cost of roughly $20 per tonne of ore now has to be subtracted from the value of the ore. Applying a 75% recovery to the average grade of 2 grams per tonne gold leaves us with a recovered grade of 1.5 grams per tonne gold. Assuming a $1,500 gold price we get an average per tonne value of ~$72.
