Photos of Natural Silver Ore Silver minerals Crystal

In many deposits located in desert regions, silver sulfide minerals like acanthite argentite, stephanite, and polybasite or oxidized by exposure to air and water into a silver chloride, also known as cerargyrite. as a result, this type of silver ore is only found near the surface. Once miners get down below the water table, this type of mineral and ore will disappear and only sulfides will be found in its place.
