RE:Taguas SART Plant would reduce costs by $120 USD/oz Au

RE:Taguas SART Plant would reduce costs by $120 USD/oz AuGanndolph, thanks for an interesting review of the possible processing at Taguas. As I read your summary of an added SART, with copper recovery, a 10% added silver recovery as well as possible cyanide recovery we are looking at a total of about 0.5 + 1.0 + 0.5 MUSD in additional revs/cost savings and a 1 MUSD operating cost on a quarterly basis. That would generate a surplus of 4 MUSD per year, investment of 20 MUSD gives 5 years pay-off (undiscounted). With the current LOM of about 10 years a decision to invest in a SART could go either way. Or did you include the depreciation of the SART in the operating costs? If not, the level of added silver recovery would be crucial, or if they could add more resources in the coming exploration program extending LOM/annual processing rates.
