The "DIRT" went 11.8 grams per tonne, page-79

Thanks for your post Esh ... may i ask what your personal thoughts are in consideration to

the conclusion is that the gold in the conglomerate at WWR was basically formed by water containing chemically dissolved gold (and/or gold as minute inclusions in various minerals)
flowing in creeks/rivers into a big basin during the Archean period when there was not much oxygen or possibly no oxygen at all in the earths atmosphere. The theory those authors favour if I understand it correctly is that bacteria (carbon based life) living in the creeks/rivers somehow caused the dissolved gold to form into micro/macro gold grains and then further process of water movement could have caused the gold associated with carbon to become freed from the carbon later.

It is an interesting prospect and occurrence to consider , be interested in your hunch on Purdy's Reward and Beatons . You certainly have deep thought and experience to benefit us all .
