Vargas, they have between 50 to 70 MM tons on the first sq km, and most people assume that the concentration is closer to .25 oz/ton. At .05 oz ton, I doubt that any hot leaching (which of course cannot be a low cost heap leaching) with fine grinding would be cost effetive, but at .25 oz/ton, you have much more leeway, the breakeven would be around $75/ton, and possibly higher because of the potential recovery of Pt and other PGM.
