Rocks gems and minerals you may find in the desert

It's very unlikely that you will find silver ore in the desert. You may look right at it and not know what your looking at. If it is exposed it will probably be almost black in color from oxidation. If you own any real silver (dinnerware or jewelry) you'll know this when you have to polish it.

Sedimentary exhalative deposits - Wikipedia

Sedimentary exhalative deposits (SedEx or SEDEX deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulphide minerals. SEDEX deposits are hosted largely by clastic rocks deposited in intracontinental rifts
