Cost is the issue, whatever the solution. The question is how to increase processing of the fines, which will eventually cease to be a problem.

The problem is that the CIL circuit doesn't have enough capacity for the volume of fines they need to process:

...the operation of the CIL circuit has been hampered by the excess quantity of fine material (smaller than 150 microns) in the material fed to the plant....

The process plant was designed by MDM Engineering as a hybrid gravity/CIL and heap leach operation, where coarser material would be delivered to the heap and a significantly smaller quantity of finer material would undergo the gravity and CIL processes following scrubbing....

Over the next few years, it is expected that the plant must handle a higher fines content than originally tested. Fines are expected to decrease later in the mine life.

So, the problem is how to increase capacity of the gravity/CIL circuit over the next few years (through 2017?). Alternatively, they could expand the heap leach operation, while stockpiling the excess fines. Or a combination of both.
