Posted By Gold Refinery of San Diego

Gold Refinery of San Diego now offers xrf gold assays at our buying office on Mission Gorge Rd.  Previously we only did assays at our refinery.  Now we can do assays on the spot at our buying office.


X-ray flourescence allows us to test gold in seconds.  We can do a 90 second test and detect the exact percentage of gold, silver, platinum, and/or paladium content in a sample with a margin of error as low as 0.01%.


XRF gold assays are free (as-needed basis) to people interested in selling gold to us.


If you are not interested in selling us gold, but you are interested in having a sample tested, we can help you for a small fee.  If you are interested in purchasing an assay, call us before coming by.  We will advise you when you can come by and how to prepare your samples.
