Apologies, this was a Reserve Upgrade of 1.5Mt. Based on 325ktpa output, the 1.5Mt upgrade equates to a 4.6 year mine life extension! or almost double the original 5.25 year mine life. Based on the max output of 650ktpa this equates to an additional 2.3 years.
Bottom line, based on existing drilling and some new exploration success it SHOULD be expected that the LOM should be AT LEAST 10 years @ 650ktpa (6.5Mt in total) versus the start up case of 5.25 years @ 325ktpa (1.7Mt in total), nearly 4 times the original study!!
