The analysis uses Q2 2013 US dollars, no gearing, a 30% income tax rate and a 100% equity post-tax model. Base-case prices are US$1,200/troy oz. gold, US$22/troy oz. silver and US$3/lb copper. The PEA is preliminary, includes Inferred Mineral Resources considered too speculative geologically to be categorized as mineral reserves, and has no certainty of realization. The incorporated December 16, 2012 Inferred resource totals at the 30 gpt AgEq reporting cutoff cover the combined MMT and Santo Nino deposits, not solely the MMT Starter Pit. The current issuer does not treat this earlier study and its underlying resource as current. Shown only as historical context.
