Traditionally, since the middle of the 19th century, one of the main sectors of the economy of Colorado has been the mining industry.
Gold, silver, coal and even diamonds were mined here. In the seventies of the XX century, the rapid growth of the economy of the state of Colorado led to oil production.
Today, the mining industry is not so important for the economy of Colorado, most of the mines have been developed and abandoned, but, nevertheless, new large deposits of oil and natural gas have been explored in the state and are being produced. The development of molybdenum and oil shale mining in Colorado is promising, and gold mining continues.
Agriculture in Colorado is characterized by growing grains (mainly wheat and corn) and raising cattle. In recent years, winemaking has been actively developing in the state.
