Concentrates are from my Colorado placer mining project.

Note they still contain some amounts of gold – these should run ¼ ounce a ton according to fire assay from Hazen Research. In addition, according to xrf analysis these concentrates do contain the suite of platinum group metals. If you can extract them – let me know!!Approximate Composition
