2,700 mtu of wolframite from ROM of 6,000 tonnes from the underground mine per month. With the decline shaft, this increases to 15,000 tonnes and assuming the grade is sustainable at 7.11 kg/t will produce 6,700 mtu of wolframite per month.
Gravity processing plant capacity is 40,000 tonnes per month. Mixing ore from the open pit and tailings with ore from the underground mine will be needed to extend the life of the mine to 15 years so these will come into play in the future.
Current ATP price is $277/mtu.
When RHA reaches steady production, I calculate sales from anticipated monthly output from the underground mine only:
With 4 month stope development
2,700 mtu x $277/mtu = $747,900 per month
With construction of decline shaft
6,700 mtu x $277/mtu = $1,855,900 per month
Zero capital cost due to govt funding of $6m.
Without KME, operating cost is $300,000 per month. (based on 15 months cashflow from the RHA Technical Report and Development Plan RNS 3/10/18)
Not sure what the operating cost is with KME on board and when the decline shaft is constructed but there is a big saving to cost of mining operations and labour.
