    OK, since several people have questioned my math, here it is. 

    12.94 OZT gross - 1.35 OZT tare = 11.59 OZT net
    divide by 20 for 14/20 gf = 0.58 OZT 15 Kt. Gold
    divide by 0.582 for 14 Kt. = 0.34 OZT gold
    yield reported by refiner - 0.13 OZT gold
    actual recovery = 38%

Cheers.
