Hi LittleWing
if you focus on the conceptual mining study from 2021, what we know is that case 10 generated the following (all in AUD);
Revenue: 6,627
Capex: 1,454
Opex: 4,152
BTCF: 1,021
If we then apply some super simple assumptions to this, these are finger in the air to give an indication of impact
Revenue: Assume 90% (We lose some of the metals due to concentrator but gain a little in the recovery process which is my understanding of how this works)
Capex: Assume 85% (I am making this up, assuming everything is smaller but offset by cost of concentrator)
Opex: Assume 75% (I am assuming 50% of the opex relates to processing and this cost is cut in half)
This generates the following
Rev: 5,964
Capex: 1,236
Opex: 3,114
BTCF: 1,614
These numbers and assumptions will obviously be drastically wrong and don't consider any of the new material from drilling campaign but give an indication about the potential upside from this pre-concentrator. *** packet calcualtion on this increased BTCF would be that it adds 400-500m AUD to the NPV8.
I am a bit more optimistic about BR than I was last week and looking forward to the conceptual economics being released baking in the pre-concentrator and hoping for a breakeven price sub $4/lb
Cheers
