<<If the most recent results were done on a sand and gravel segment then it was definitionally not refactory ore but most likley alluvial.>>

All depends on the material making up the S&G layer. Is it material from Franklin Lake itself - zeolite type. In addition, results show the J/L process effective for increasing the grades in that interval, suggesting there is a refractory component.

The Franklin Lake is unique in that its compositional materail, zeolite, has acted as a sponge trapping metals that have been leached by the river over millions of years. A big concentrating depo. Metals in the river water will exchange with other elements in the zeolite, clay etcs. This process is not simple and the metals are in some sort of chemosorbed state, thus difficult to extract. The S&G layer probably has some level of capacity to chemosorb these metals, albiet lower than clay, thereby producing a component of refractory ore.

<<If this is the case, conventional wisdom would suggest that platinum and gold would not be comingled as in a refactory clay. This could indeed explain why no platinum was detected as it would indicate a different type of ore.>>

Could also do with the collector used in the assay procedure. Lead is less effective than Cu or Ni. I'm assuming Pb was used in this case. You should also see a small increase in the Au values with a Cu collector.
