only thing I can tink of is to use volume of rock sluiced and recovery rates. But i'm not that smart. I've emailed the ministry of mines to see if there is a database of gold recoveries from placer operations. Specifically Joel white.

how often do they run a cleanup on an operation this size? The gold recovered from the bench was fine and had a purity of 820. The creek gold was more coarse with a purity of 800. In 1998 to 2002, fineness ranged from 770 to 810. Gold was generally coarse, with smooth rounded nuggets. In an average cleanup of 340 ounces, 67.05 raw ounces were -30 mesh; 122.50 oz were -20 mesh, 67.30 ounces were -10 mesh, 46.15 ounces were +10 mesh and 36.50 ounces were +20 mesh.
