The Silver Peak mining district in Esmerelda County, Nevada was very productive in the late 1800s, but work continued through the early 1900s, and is still a site for ongoing open pit gold mining to this day. This area produced many millions of dollars from silver ore which looked like this specimen. Quartz is considered the host rock for many silver deposits. Quartz is a crystalline structure that has a white to clear appearance. Bright white quartz with streaks of gray are a good indicator of the presence of silver ore. A rock containing silver will have a dark, almost sooty appearance or dark crystals within the rock. There are several different types of silver ore in the world depending on the geography. Some have gray spider-like veins running through the rocks, while others can be more gray or black in color.

Native Silver Found as wire silver, in thin sheets, in tree-like shapes, and as octahedral crystals. Colour and Streak—silver white. When found in veins is usually tarnished on the surface. Silver often plays second fiddle to another precious metal, gold, but this element has special properties that deserve a good look. For example, of all the metals, pure silver is the best Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration, Like copper, silver reacts with sulfur and its compounds; in their presence, silver tarnishes in air to form the black silver sulfide (copper forms the green sulfate instead, while gold does not react). Unlike copper, silver will not react with the halogens, with the exception of fluorine gas, with which it forms the difluoride. Generally, silver in its native form does not look like shiny silver-like in silverware. It looks more like a silver-colored rock which is uncommonly heavy. Sometimes, native silver is so tarnished that it cannot be distinguished by color at all. Most people think of nuggets and such, but the truth is that very little comes from nuggets - nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles. This webpage is created to show what some of those ores look like.
