It comes down to their JORC report and the average grade. There has been a discovery of a vein that has an 11 g/t. Their average is roughly 5-6. There is also the new horizon of copper leaching and the discovery of coal. They have been able to strike up a deal with Swan Energy to develop the Phillipino islands that they operate in. These islands are short of electricity and the coal will be much needed to develop the Phillipines in order to sustain a community.
In laymans terms their mine life is about 50 years easy. They have good grades. And their AISC of 900 is expected to lower with the strengthening of the US dollar. That 900 earns them 3rd place on the AISC podium.
