Looking closer at the definition of Inferred... I will be sticking closer to the number for Meas + Indicated metals. The last sentence below pretty much says: "don't put any value on inferred".
The reason I insist on the inferred Chappy is because Teck doesn't shy themselves on putting it their ''main projects'' Presentation
Notice for Antamina they put : 1.3 Bt (M+I+I) resource
On the presentation that mentions Schaft Creek they put 1 Billion tones, not adding teyh inferred...when they should also put 1.3 (M+I+I)
We all know we have alot mnore metal than indicated and measured resource...Teck knows it to:
Less than 1,500 acres of the 50,000 acre Schaft Creek property has been explored using modern exploration techniques. To identify/add value over and above that established by the feasibility study, Copper Fox is considering the merits of completing a high sensitivity airborne geophysical survey over the entire Schaft Creek property to identify other potential areas of porphyry style mineralization.
