An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.

Stibnite is also the mineral name for antimony ore. Mining for gold and antimony began at Stibnite in 1931. Later a body of rich tungsten ore was found. During World War 11, Stibnite produced ninety-eight percent of America's antimony, and much of her tungsten. Both metals were vital for making machines and weapons for fighting the war.

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.
