The Company participated in the construction of Denison Mines Quintette Mine in Tumbler Ridge, BC. We constructed the roads, bridges all the major infrastructure for the mine in one of the most isolated locations in the province. The Company installed the process facilities, storage facilities and the electric rail lines that delivered the coal to the port city of Prince Rupert. We stripped the over burden and performed the mining of the site until Denison Mines brought in their own forces to excavate the coal for export.
The Company has developed several mines and performed contract mining in the Powder River Basin for close to 50 years. The mines straddle northern Wyoming and southern Montana. The company has delivered turn key projects for the coal companies as well as performing the striping, reclamation and the installation of load out facilities for Union Pacific and BNSF railroads. The Company has built several coal bed methane extraction facilities in the Basin along with the pipelines. The mines supply 40% of the country’s annual coal production.
MK became a savior of sorts when it employed over 10,000 locals during its work on the Cerrejon coal mine.
It’s located in the basin of the Rancheria River, southeast of La Guajira Department in Colombia. It is an open-pit mine, and is one of the largest mines in the world. The coal mine was divided into three main corresponding areas Cerrejon North Zone, Cerrejon Central Zone and Cerrejon South Zone. The mine extends over 170,000 acres where the company moved 80,000,000 cubic yards of rock and dirt annually.
The company showed its true grit and might going full tilt on the Rio Blanco Copper mine in Chile, hewn out of solid rock in the forbidding landscape of the Andes Mountains. We truly earned our stripes in one of the most isolated ranges on the planet.
The Bingham Canyon Mine, also known as the Kennecott Copper Mine, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. Bingham Canyon Mine is the largest man-made excavation in the world, and is visible with the naked eye from space. The Company performed all the infrastructure and continues to perform contract mining at the site.
The Kayenta mine is a surface coal mine on the Navajo Indian Reservation in northern Arizona. About 400 acres are mined and reclaimed each year, providing about 8 million tons of coal annually to the Navajo Generating Station. The Company began operations in 1973 supplying the Navajo Generating Station near Page, Arizona and the majority of our employees at the site are Navajo Indians.
The North Antelope Rochelle Mine is the second largest coal mine in the U.S. Located in Campbell County, Wyoming, about 65 miles south of Gillette, it produces 107,700,000 tons annually. The company started work on the site in 1983 and the mine was opened in 1984. We used draglines and trucks and shovels to remove the overburden. Trucks then haul the coal from the three pits to trains for shipment to customers. In 2012 the Morrison Knudsen won an award from the Department of the Interior for its reclamation efforts over the life of the mine.
The Black Thunder Coal Mine is a surface coal mine in Wyoming, located in the Powder River Basin which contains one of the largest deposits of coal in the world. Black Thunder is the second most productive mine in the United States, providing the U.S. with eight percent of its coal supply. In 2011, the America Revealed “Electric Nation” episode aired on PBS and features Morrison Knudsen’s contribution to the development of Thunder Basin’s Black Thunder coal mine.
The Fort Knox Gold Mine is an open pit gold mine in the Fairbanks mining district of Alaska. It is was built by the Company in some of the planet’s harshest environments. In spite of 55 below zero cold the company completed the project three months ahead of schedule. The Company has just started another mining project in the same gold belt not far from Fort Knox.
