Hi Stoops
Commonsense tells me that it is more likely the .03% ore upgrades to 8% after the wet plant and the .05% ore upgrades to 12%
Still leaves me in doubt how 12-18Mt of ore at
ROM =0.05%-0.03% Treo could ever be contained in
~120,000 tpa
CHARLEY CREEK jorc is Treo at 292 ppm (.0292%)
They must be cherry picking the resource to have a
ROM =0.05%-0.03% Treo
If you have an average ROM of .04% and a 80% recovery
12Mt x .04% = 4800 t Treo x 80% recovery = 3840 t Treo
18Mt x .04% = 7200 t Treo x 80% recovery = 5760 t Treo
The maximum Treo contained in 120,000 wet plant output
is between 3.2% and 4.8%
