Q

The operating cost for a gold mine is 55 $/ton. The recovery at the mill is 90%. At a gold price of $400/oz, what is the break-even cutoff grade in oz Au/ton?
0.15 oz Au /ton 0.12 oz Au /ton
6.55 oz Au /ton
0.2 oz Au /ton

A

0.15 oz Au /ton

solution
The cost per ton is given as $55/ton. The mill will recover 90% of the contained Au. Therefore, 1 ton of ore yields G*0.9 oz Au, where G is the ore grade in oz Au/ton. At a gold price of $400/oz, the revenue per ton is $400 * G * 0.9. The cutoff grade G can now be calculated from the equation:
Revenue/ton = cost/ton
$400/oz Au * G * 0.9 = $55/ton
G = 0.15 oz Au /ton
