Sherritt International Corporation announced that commercial production has been achieved at the Ambatovy nickel operations in Madagascar. Commercial production is defined as 70% of ore throughput of nameplate capacity in the Pressure Acid Leach (PAL) circuit on average over a thirty-day period and is the point at which all revenue and operating costs cease to be capitalized. The focus at Ambatovy remains on optimizing operating performance to achieve nameplate capacity (60,000 tpa finished nickel and 5,600 tpa finished cobalt, 100% basis).
