The Company's Preliminary Economic Assessment (PEA), full document issued February 4th, 2013, indicated that the proposed mine was cash flow positive for both the open-pit and underground scenarios independent of one another.
The PEA has served as the starting point for the determination of extraction process optimization with the goals of reducing cash cost per ounce and related capital expenditures. Also in this first PEA, as part of this optimization process, the Company included scenarios that increased the grade of the open pit resource from 1g/t Au to 2 g/t Au. Going forward, the Company will conduct a thorough review to evaluate whether the increase in grade will in fact lower cash costs per ounce as well as associated capital expenditures.
