Anyone has an idea what's the best way to estimate (ballpark) the FS/PEA (2021) total production when assuming the recoveries (%) they had in 2008?
| PFS (2008) | FS (2013) | FS/PEA (2021) | |
| Total production (LOM) | |||
| Copper (M lbs) | 4,762 | 4,875 | 6,120 |
| Gold (T oz.) | 4,493 | 4,213 | 4,936 |
| Silver (M oz.) | 32.5 | 25.1 | 31.1 |
| Moly (M lbs) | 255.2 | 214.9 | 282.2 |
For my numbers, I used the 2008 numbers, adjusted based on mine life (e.g. 22.6 years vs. 21 years), added 33% for the increase in tonnage (from 100k tpd to 133k tpd) and adjusted that total with a grade ratio (e.g. 0.25%/0.26%). Does that make sense?
Or else, should I possibly use the 2013 numbers, do a rule of three for the recovery (%) and then add 2.3% for the increase in tonnage + adjust with a grade ratio?
I might be comparing apple with oranges here, not sure. How were they able to obtain so much production with only 100k tpd in 2008?
Any help would be appreciated.
