strip ratio is higher because they used a higher cut-off grade of 0.6g/t inlieu of 0.4g/t au.

the strip ratio without any context doesn't mean anything.

it's the option that generates the higher/better financial metrics that counts.

Some deposits, it's better to use a lower cut-off grade because the grade profile at a higher cutoff grade won't improve IRR/NPV that much & others different.

Matt Greentree, advised that economic cut-off is around 0.4 g/t au but what generated the best financial outcomes was to increased the cut-off grade at 0.6g/t au, mine the highergrade zones.

It is all on record here. If you don't agree or don't trust. all good. each to their own



If you look at their mineral resource table the resource at the lower cutoff grade is 2.73Moz. which is approximately a 35% uplift from the 2Moz.
