Tim, <<don't have a traditional placer deposit>> They have to start with some model and it does seem to serve them. Maxam's Peoria does have some placer content, I think it was you that said a friend of yours saw free metal? We may see the connections of sample size with the paper on desert dirt assays, I hope. At least people can now begin to understand why they just can't take a small sample from the surface and do an assay for their due dilly. Runyon told me that he constantly gets requests from stock brokers and others for a small sample so they can assay it. Next time you talk to Coggins, see if that's what he did. <<They were applied to low grade open pit copper>> I understand that Hewlett did most of the copper resource determination for the Southwest. Older doesn't mean dead, I promise you. <VBG>

Tim, I also want to relate something I recall that Runyon told me about doing a fire assay on desert dirt. I don't recall the exact details, but the technique consists of milling the ore to different screen size and then fire assaying each fraction (one of Hewlett's attachments shows an example?). There seems to be minerals (or elements) at different screen size that can kill a fire assay result. Anyone that just tries to fire assay the raw ore at 200 mesh wouldn't get a good result, little or nil. Recovery however always does extract more metals than fire assay shows because it's not sensitive to the inhibiting conditions those minerals have on the fire assay. That may be the explanation why recovery produces better results than fire assay for desert dirt. Does this make any sense? I hope we learn more about those details.
