Hello. Currently we been testing dirt/sand/rocks by using AR as a qualitative test in different areas of a property we own in San Diego California local mountains. It took us some time to figure out that we are dealing with microscopic gold that will not stick to any sluice even after trying different mats, panning is out of the question because the microscopic gold in the dirt/sand a good portion of the gold travels with the clay and it's lost by panning. We experienced same results running concentrates on blue bowl and miller table we just lose it. Since we are finding that testing qualitative with AR is promising we would like to find our options to test larger samples like a ton per day or half a ton or even a couple thousand pounds will be satisfactory. Hope there's something out there that is reliable and validated to capture microscopic gold.
Thank you
