Mining Weekly reported that Curis Resources has completed a prefeasibility study (PFS) on its Florence Copper project, which assigned a NPV of $748-million to the project.
As quoted in the market report:
The base-case economics indicated an internal rate of return (IRR) of 38% and a pretax 2.4-year payback of the $129-million capital costs. This represented an 18% decrease from the initial capital cost estimate in the 2010 preliminary economic assessment. The commercial operating life of the project was also extended from 19 to 25 years.
