Ahh that explains why my numbers are different. I made two assumption different than yours. I assumed:

A) Production ramps up to 150,000 tpd in the 5th year. I assumed this because the 2011 AIR states that production may be this high.

B) Proven and Probable grades would be higher than the Measured & Indicated grades. This was the case for the PFS so I just assumed it will hold true for the FS. The Port Agreement terms also indicate that production should be higher than the PFS.

Thanks for the info! It's always helpful to compare notes with others.
