Is there likely to be ongoing expansion of the resource or have the limits of the deposit been reached ? Also has anyone seen an NPV of the project? Stock looks attractive, significantly derisked, good margins, low capex etc Looks but mine life currently around seven years only looks a little short ? I'm guessing NPV around $700m using 5% WACC (but that's a real guess).
