Interested to hear thoughts on the ore reserve for T3 that will underpin the investment case. As reference we had 21mt @ 1.02% Cu in the PFS - which using $3/lb, 76c AUD, 8% dr, and 2.5mtpa throughput yielded an NPV pre-tax of A$370m.
The 21mt was based off the JORC from August 2017.. and a 0.34% Cu cut-off. It was basically 85% of the measured resource and 89% of the indicated. The lastest jorc in July 2018 showed indicated resource of 37mt @ 1.14% Cu at 0.4% cutoff and they’ve since done further infill drilling. Grade is king in these deposits. I’d love to see the reserve up to say 32mt @ 1.1% Cu (DFS modelled as 11 -12 year, 3mtpa operation) but a lot of that high grade stuff probably sits outside the pit shell and more in the veins that will go into the UG mining study. Thoughts??
