The revised after-tax Net Present Value \(NPV\) at a 10% discount rate is now US$370 million, with an Internal Rate of Return \(IRR\) of 315% and a payback period of 0.5 years. These positive changes stem from adjustments to tax calculations and a clarification of the silver recovery assumption, leading to a 38% reduction in Cash Cost and a 36% reduction in All-In Sustaining Cost. Reasoning: The company corrected cost metrics and economic results for the Calcatreu PEA, leading to substantial improvements in NPV, IRR, and operating costs, making the project more attractive. - Positive factor: Increased after-tax NPV by US$36 million - Positive factor: Increased after-tax IRR by 33 percentage points - Positive factor: Reduced after-tax payback period by 0.1 years - Positive factor: Significantly reduced Cash Cost by 38% and AISC by 36% - Positive factor: Clarification of silver recovery assumption to 45% \(already used in model\) - Negative factor: Initial reporting errors in previous news release Facts used in scoring: 9 ## Classification and evidence **Initial Reporting Error** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The news release corrects several previously reported economic metrics and a recovery assumption.

Why it applies: Corrections to tax calculations and silver recovery assumption significantly improved NPV, IRR, and reduced costs. Evidence · text > The correction to the regional development tax calculation reduces the projected Cash Cost and AISC, shortens the projected after-tax payback period and increases the projected after-tax NPV and IRR through its effect on the underlying cash flows. ## Extracted facts Stored fact records: 1.
