It would be a whole lot better all the way around if you would just post a file of the assay/report from the "refiner". By the way the implication that you are the teacher here is beyond comprehension. Your throwing numbers at us that none of us has ever seen processing the same type of material and you expect us to just take you at your word? Never heard of not even a hobbyist processing the types of material you mention and mixing them together, why would you mix these kind of metals together unless you were making dore bars. I would look for a different refiner. This is not meant to offend you in any way, but if you are, you should move past it and show us the facts. If you can't provide the facts then it's safe to assume we will all move past this thing.
Be the person your pet thinks you are.
