If I were to send in placer gold to a lab to get the gold and other metals (mostly silver) purity levels assayed what would the best most accurate type of assay to do?
I have sold placer gold to a company that smelts it then does and XRF on the bar then pays based on that but I am not happy with this company for a couple different reasons so would like to have my gold pre assayed by another lab before selling next time.
There is another gold buying company that sends the gold to a lab that does fire assay then pays based on that. But I would like to get an independent assay from a lab or labs that aren't buying the gold so that they have no vested interest in the gold.
When I phoned around to some local labs (I'm in BC Canada) the couple of them that said they could do it said they needed about 10 grams of it and would fire assay it and would give my gold back afterwards.
I thought 10 grams was quite a bit to do a fire assay on but both labs said the same thing. Is this typical for assaying placer gold by fire assay?
