As a Business Analyst for a large multinational mining company, I think I can safely relate some of my experience in creating a large processing plant that exceeds reasonable mining capacity. At the moment, on a 50 ktpa milling capacity, you have a five year mine life. That gives you five years to explore and keeps costs low for maintenance, etc. If mining and processing capacity were to double, the mine would need to develop fast enough to keep up with production or risk becoming a bottleneck early in the process. Terribly risky. I've seen it happen where they refuse to ramp down production to save costs due to pride. I'd love them to ramp up though if they could guarantee five years of mine life at 100 Ktpa ;)..
