They gave a few examples where drilled grade and mill grade differed materially. The first was with Agnico-Eagle that has a deposit (sorry forget the name of the deposit) that is located between 500 and 800 m of depth. When they drilled it, they got a 43-101 report indicating about 2t/g-and proceeded to mine it!! They are mining it now and have a mill grade that is over 4 g/t.

Hi Frank,

you are probably referring to Agnico-Eagle´s Goldex mine (PRB has a NSR on parts of that one, btw):

people interested have a look at my earlier post on this hub and do some DD, very interesting:

Agnico Eagle´s Goldex Mine - Steady State Mine Continues Strong Performance

The 100% owned Goldex mine in northwestern Quebec began operation in 2008. Proven and probable gold reserves total 1.6 million ounces from 24.7 million tonnes grading 2.0 g/t.

The Goldex mill processed an average of 7,410 tpd in the first quarter of 2010, continuing to exceed the design capacity for the plant of approximately 6,900 tpd. During the first quarter of 2009, the plant processed 6,770 tpd.
