Recovery Grade Improvements

[eebler]

If you assume that 100% of the current estimate is mineable (rarely the case, but assume it for now) then the improvement in recovery grades announced today based on the current resource size translates roughly as follows:

- avg increase of 5% copper recovery produces an additional 435M lbs of copper
- avg increase of 17% moly recovery produces an additional 57M lbs of moly
- avg increase of 23% gold recovery produces an additional 683K ozs of gold

Base case values from recent PEAs values seem to run around:

- $2.25 / lb copper
- $15 / lb moly
- $1015 / oz gold

Which means economics of Taca Taca just improved by:

- 2.25 x 435,000,000 = $978 M
- 15 x 57,000,000 = $855 M
- 1015 x 683,000 = $693 M

Total Revenue Increase = $2.5B

Figure a very conservative cash cost of 50% of the metal vaue, and that should mean an additional $1.25B in operating margin.  And to again be conservative, figure half of that disappears for taxes, royalties, admin, etc., so it still produces an extra $600M or so of net income. 

Math right?
