Here are the workings for the more ambitious schedules - still only for 19 years, which is obviously conservative given the size of the resource, but makes comparison and discounting easier.
1. 603kt LCE (17.5ktpa 4 years, 35ktpa 15 years)
2. 890kt LCE (20ktpa 2 years, 50ktpa 17 years)
3. 1,590kt LCE (20ktpa 2 years, 50ktpa 3 years, 100 ktpa 14 years)
4. 2,390kt LCE (20ktpa 2 years, 50ktpa 3 years, 100 ktpa 6 years, 200ktpa 8 years)
One simple method for estimating an NPV value is to pick a realised cash flow per kt of LCE and discount it for the mining plan schedule. I used $3,000/t (consider it after all costs and taxes if it seems too low!) and 50% previously, but other values are available. ;-)
1. Percentage of the 603kt LCE associated with the JV is 11.95% (page 138 of the feasibility study), which is 3.6% to KDNC, 21.7kt LCE. (KDNC 3.6%, BCN 48.2%, Ganfeng 48.2%). KDNC value 21.7kt * $3,000/t * 50% = $32.5m
2. Assume 50% of the 287kt of additional LCE in 1 above is from the JV area.
KDNC 21.7kt + (287kt * 50% * 30%) = 64.8kt LCE (KDNC 7.3%, BCN 46.35%, Ganfeng 46.35%) KDNC value: 64.8kt * $3,000/t * 50% = $97.2m
3. Assume 70% of the 700kt of additional LCE in 2 above is from the JV area.
KDNC 64.8kt + (700kt * 70% * 30%) = 211.8kt LCE (KDNC 13.3%, BCN 43.35%, Ganfeng 43.35%) KDNC value: 211.8kt * $3,000/t * 50% = $317.7m
4. Assume 90% of the 800kt of additional LCE in 3 above is from the JV area.
KDNC 211.8kt + (800kt * 90% * 30%) = 427.8kt LCE (KDNC 17.9%, BCN 41.05%, Ganfeng 41.05%) KDNC value: 427.8kt * $3,000/t * 50% = $641.7m
Better @mr.james? ;-)
Clearly my own estimates based on my own assumptions - please do let me know if anyone spots any mistakes in reasoning or calculations! DYOR. IMHO. LoL.
I'd personally be quite disappointed if we let Sonora go for anything less than $100m now the cat is poking its head out of the bag on their expansion plans!
Ob.
