When buying your gold, we now offer on the spot XRF gold assays.  We have invested in the best technology available for assaying gold in San Diego.  If you have gold, silver, platinum, or palladium for sale, we have the most advanced x-ray technology to assay your precious metals.  This technology allows us to pay you our absolute highest payouts.

If you are NOT interested in selling us gold, but want to have a sample tested for gold with our XRF machine, we can help you for a $40 charge per sample.  Please contact us for directions on how to prepare your sample.  We do NOT take walk-ins for testing only.

NEW: For miners we offer fire assays.  Crushing, Drying, Pulverizing, and Grinding are all available for fire assays. Please call for a price quote.


HOW ACCURATE IS YOUR ASSAY TEST? The test has a margin of error as low as 0.01%

DO YOU ONLY OFFER XRF ASSAYS? No. We offer XRF Assays and Fire Assays. Fire assays are recommended for testing dirt and rocks for gold and other precious metal content.
