To quote Darkstone:

"...the upgrade as a percent of the current reserve ...represents a 50% upgrade ...the operating result is outstanding - 30% margin, nil debt, $59M cash on 7 or 8 months trading, higher prices for the next 12, falling costs trend, unvalued reserves which post BD events imply will have a value and output presold at higher prices for next year is good by anyone's standards."

I hope that helps.
