Nevada is the most mineral-rich state in the union. Outside of the Las Vegas and Reno metropolitan areas, mining plays a major economic role in Nevada. By value, gold is by far the most important mineral in the state. In 2013 alone, the mining industry contributed approximately $8.1 billion dollars to Nevada's gross domestic product. This included over 169 metric tons of gold accounting for 74.5% of the U.S. total and helped make the U.S. the third leading gold producer in the world. Other minerals mined in Nevada include silver, copper, construction aggregates, gypsum, diatomite and lithium.
Most of the mines listed on this page are active, corporate operations. Some offer public tours, but most do not. The convention production team will try to arrange tours of the mines near Ely as part of our schedule of events. Please do not try to access these active mine sites without permission from the owners. You could be subject to arrest for trespassing.
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2S3. This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek stibi through the Latin stibium as the old name for the mineral and the element antimony.
Stibnite has a structure similar to that of arsenic trisulfide, As2S3. The Sb(III) centers, which are pyramidal and three-coordinate, are linked via bent two-coordinate sulfide ions. It is grey when fresh, but can turn superficially black due to oxidation in air.
Pastes of Sb2S3 powder have been used since ca. 3000 BC as eye cosmetics in the Middle East. It was used to darken the brows and lashes, or to draw a line around the perimeter of the eye. Antimony trisulfide finds use in pyrotechnic compositions, namely in the glitter and fountain mixtures.
Located only 50 miles northeast of Las Vegas, Valley of Fire State Park derives its name from red sandstone formations, formed from great shifting sand dunes during the age of dinosaurs. These features, which are the centerpiece of the park's attractions, often appear to be on fire when reflecting the sun's rays.
Complex uplifting and faulting of the region, followed by extensive erosion, have created the present landscape. The rough floor and jagged walls of the park contain brilliant formations of eroded sandstone and sand dunes more than 150 million years old.
