What rock is silver ore found in?
Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver).
How do I know if my rock is valuable?
The Hardness Test The harder a mineral is, the more likely it is to be valuable. If you can scratch the mineral with your fingernail, it has a hardness of 2.5 Mohs, which is very soft. If you can scratch it with a penny, its hardness is 3 Mohs, and if it takes a piece of glass to scratch it, the hardness is 5.5 Mohs.

Look for crystals in igneous rocks. Examples of igneous rocks are gabbro, granite, pumice and obsidian. Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands.
