Well, per Dayne Chastain's assay report, looks like Lucky Linda No.1's placers are rich with precious metals. "I must add that as an experienced refiner for over 20 years, I was amazed at the amount of precious metals produced from this ore."
Re: As mentioned before, the richest placers are not necessarily those occurring close to the source.Much depends on how the placer materials were reworked by natural forces.
