  1. Colorado Mining A report by john B.

  2. History in short. • Gold found by Cherokees in the South Platte, 1850’s • Gold rush began in 1859. • largest gold rush in history • Denver area initial source. Produced very little gold. • Major discoveries in Clear Creek and Cripple Creek.

  3. History cont. • Silver boom in 1879. • Boom ended in 1893. • Gold production peaked in 1900. • Unevenly declined. • Gold spiked in 1935. • Ended in 1941. • Carnotite boom in 1950’s. • Molybdenum fist mined in 1918.

  4. Mineral Deposits. • Mineral belt contains most of mineral deposits in the state. • Most uranium deposits in the Uravan mineral belt. • The green river formation which includes the Pinceance basin holds over 60% of all the world’s oil shale reserves, and the only known source of natural sodium bicarbonate.

  5. Molybdenum facts. • Molybdenum is an element used in stainless steel and high temperature applications.( light bulbs nuclear reactors ect.) • Molybdenum is the most important mineral mined in Colorado today. • The Climax mine recently reopened.

  6. Colorado coal mining. • Coal has been mined since the first settlers arrived. • Colorado is 7th in coal production in the U.S (6th according to the CGS.) • Coal from western states is cleaner than that of the east.

  7. Coal Issues • Coal produces CO2 which is a greenhouse gas. (No real scientific proof behind man made global warming.) • Produces pollutants such as carbon monoxide and sulfur dioxide. • Non renewable.

  8. Oil Shale Energy. • Oil shale is accentually oil that never matured. It holds kerogen. • Oil shale is technically organic marlstone. • Originally referred to as rubber rock, this rock will actually burn. (some found this out the hard way) • There is an estimated 1.5 trillion bbl. under the western states.

  9. Problems With Oil Shale. • Oil shale has an energy density comparable to that of baked potatoes. • Traditional refining methods for oil shale requires a lot of energy. • In collecting significant shale to refine and produce oil the land would be full of 2,000 ft holes in the ground.

  10. Colorado Natural Gas issues. • Rigs scar the landscape. • Rigs produce noise and threaten to put some animals such as the greater sage grouse on the endangered species list. • A process called hydraulic fracturing pumps water sand and many non disclosed chemicals into the ground and has been blamed for contaminated wells.

  11. N.G. issues cont. • Trucks that transport these chemicals may leak or spill. • Waste water is stored in open pits which may leak chemicals. • N.G also reduces other industries such as tourism. Waterfall comprised of spilled drilling fluids.
