Upgrading my resource estimate20 Oct 2018 18:13
I'm upgrading my estimate of contained copper at Kabala. I think we are now probably in the region of 600kt to 700kt of contained copper equivalent (up from 400kt to 500kt). If the strike length is now 750m vs. 500m as we are now finding mineralisation going West, then this is a major extension and resource upgrade.
600m x 750m x 70m (avg. depth), density 2.5t / cubic metre (SP Angel's estimate), so 31.5m cubic metres x 2.5 = 78mt. Assuming an average grade of 0.8% Cu eq. (a rough guess as we have higher grade zones), so we have 52.5mt x 0.8% = 630,000 Cu eq. (contained).
Still waiting to see if we go extend the strike down dip to "several km" as previously alluded to by NvS...
