Because the gold is both free-milling
and coarse, no leaching is required.
The majority of resource at Akoko North comprises shallow, free-milling
oxide ore with high metallurgical recoveries, Goldcrest said.
Blackham's plan is to optimize existing plant components and upgrade the free-milling
oxide carbon-in-pulp circuit to process current resources.
The Aurora ore is free-milling
, allowing a flowsheet using conventional gold processing techniques.
Feed for the expanded plant will be supplied initially from near-mine resources at Paulsens and after about three years from free-milling
ore at Ashburton.
