Lake City is a Statutory Town that is the county seat, the most populous community, and the only incorporated municipality in Hinsdale County, Colorado, United States. It is located in the San Juan Mountains in a valley formed by the convergence of Henson Creek and the headwaters of the Lake Fork of the Gunnison River about seven miles (11 km) east of Uncompahgre Peak, a Colorado fourteener. Lake City is named after nearby Lake San Cristobal. This area lies at the southern end of the Colorado Mineral Belt and when rich mineral deposits were discovered the native population was pushed from their tribal lands and the town of Lake City was incorporated in 1873.
Silverton is a Statutory Town that is the county seat, the most populous community, and the only incorporated municipality in San Juan County, Colorado, United States. The town is located in a remote part of the western San Juan Mountains, a range of the Rocky Mountains. The first mining claims were made in mountains above the Silverton in 1860, near the end of the Colorado Gold Rush and when the land was still controlled by the Utes. Silverton was established shortly after the Utes ceded the region in the 1873 Brunot Agreement, and the town boomed from silver mining until the Panic of 1893 led to a collapse of the silver market, and boomed again from gold mining until the recession caused by the Panic of 1907. The entire town is included as a federally designated National Historic Landmark District, the Silverton Historic District.
The City of Victor is a Statutory City in Teller County, Colorado, United States. Gold was discovered in Victor in the late 19th century, an omen of the future of the town. With Cripple Creek, the mining district became the second largest gold mining district in the country and realized approximately $10 billion of mined gold in 2010 dollars. It reached its peak around the turn of the century when there were about 18,000 residents in the town. Depleted ore in mines, labor strife and the exodus of miners during World War I caused a steep decline in the city's economy, from which it has never recovered. The population was 397 at the 2010 census. There is a resumed mining effort on Battle Mountain.

The following is a list of Registered Historic Places in Iron County, Michigan. The list includes 79 structures and historic districts that are significant for their architectural, historical, or industrial/economic importance.
The Colorado Fuel and Iron Company (CF&I) was a large steel conglomerate founded by the merger of previous business interests in 1892. By 1903 it was mainly owned and controlled by John D. Rockefeller and Jay Gould's financial heirs. While it came to control many plants throughout the country, its main plant was a steel mill on the south side of Pueblo, Colorado and was the city's main industry for most of its history. From 1901 to 1912, Colorado Fuel and Iron was one of the Dow Jones Industrials. The steel-market crash of 1982 led to the decline of the company. After going through several bankruptcies, the company was acquired by Oregon Steel Mills in 1993, and changed its name to Rocky Mountain Steel Mills. In January 2007, Rocky Mountain Steel Mills, along with the rest of Oregon Steel's holdings, were acquired by EVRAZ Group, a Russian steel corporation, for $2.3 billion.
Tahawus was a village in the Town of Newcomb, Essex County, New York, United States. It is now a ghost town situated in the Adirondack Park. Tahawus is located in Essex County within the unpopulated northern area designated to the town of Newcomb. Tahawus was the site of major mining and iron smelting operations in the 19th century. Although standing as recently as 2005, the last mining facilities have since been demolished and removed.
The Cliffs Shaft Mine Museum is a former iron mine, now a heritage museum, located on Euclid Street between Lakeshore Drive and Spruce Street in Ishpeming, Michigan. The museum, operated by "Marquette Range Iron Mining Heritage Theme Park Inc.", celebrates the history of the Marquette Iron Range. The site was designated a state of Michigan historic site in 1973 and placed on the National Register of Historic Places in 1992.
The Hull–Rust–Mahoning Open Pit Iron Mine in Hibbing, Minnesota, United States, is the largest operating open-pit iron mine in Minnesota. The pit stretches more than three miles (5 km) long, two miles (3 km) wide, and 535 feet (163 m) deep. It was established in 1895 and was one of the world's first mechanized open-pit mines.
The Central City/Black Hawk Historic District is a National Historic Landmark District that encompasses the developed areas of Central City and Black Hawk, Colorado. They are adjacent former gold mining camps in the Front Range of the Rocky Mountains in Gilpin County, Colorado, United States. For a time, the area was known as the Richest Square Mile on Earth, and was the largest urban area of the Colorado Territory in the 1870s.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
Uranium mining in Wyoming was formerly a much larger industry than it is today. Wyoming once had many operating uranium mines, and still has the largest known uranium ore reserves of any state in the U.S. At the end of 2008, the state had estimated reserves dependent on price: 539 million pounds of uranium oxide at $50 per pound, and 1,227 million pounds at $100 per pound.
The Gogebic Range is an elongated area of iron ore deposits located within a range of hills in northern Michigan and Wisconsin just south of Lake Superior. It extends from Lake Namakagon in Wisconsin eastward to Lake Gogebic in Michigan, or almost 80 miles. Though long, it is only about a half mile wide and forms a crescent concave to the southeast. The Gogebic Range includes the communities of Ironwood in Michigan, plus Mellen and Hurley in Wisconsin.
The Sterling Hill Mine, now known as the Sterling Hill Mine Tour & Museum of Fluorescence, is a former iron and zinc mine in Ogdensburg, Sussex County, New Jersey, United States. It was the last working underground mine in New Jersey when it closed in 1986, and it became a museum in 1989. Along with the nearby Franklin Mine, it is known for its variety of minerals, especially the fluorescent varieties. It was added to the National Register of Historic Places in 1991.
The Jackson Mine is an open pit iron mine in Negaunee, Michigan, extracting resources from the Marquette Iron Range. The first iron mine in the Lake Superior region, Jackson Mine was designated as a Michigan State Historic Site in 1956 and listed on the National Register of Historic Places in 1971. The Lake Superior Mining Institute said, the mine "is attractive in the iron ore region of Michigan and the entire Lake Superior region, because of the fact it was here that the first discovery of iron ore was made, here the first mining was done, and from its ore the first iron was manufactured." Multiple other mines soon followed the Jackson's lead, establishing the foundation of the economy of the entire region. The mine is located northwest of intersection of Business M-28 and Cornish Town Road.
Wyoming Highway 318 (WYO 318) is a short east-west 1.09-mile-long (1.75 km) spur route off Wyoming Highway 270 in northeastern Platte County.
The Ferris-Haggerty Mine Site was one of the richest components of the Grand Encampment Mining District in Carbon County, Wyoming. The site was first exploited by Ed Haggerty, a prospector from Whitehaven, England, in 1897 when he established the Rudefeha Mine that would later be known as the Ferris-Haggerty Mine on a rich deposit of copper ore. Haggerty was backed by George Ferris and other investors, of whom all but Ferris dropped out. The partners sold an interest to Willis George Emerson, who raised investment funding for improvements to the mine. These facilities included an engineering feat of its day by developing a 16-mile (26 km) aerial tramway to carry high grade copper mined at the Ferris-Haggerty Mine (FHM) over the Continental Divide to the smelter in Encampment. The tramway was longest aerial tramway the world had ever seen. The mine was eventually acquired by the North American Copper Company for 123 billion. By 1904 the mine had produced $1.4 million in copper ore, and was sold to the Penn-Wyoming Copper Company. However, even with copper prices peaking in 1907, the company had difficulty making a profit from the remote mine site. The company was over-capitalized and under-insured and was suffered devastating fires at the mine site in March 1906 and May 1907 which halted production. Business disputes and a fall in copper prices prevented re-opening of the mine even after it was rebuilt. Machinery was salvaged after a foreclosure in 1913. A total of 23 million pounds of copper ore was extracted from the mine during its life.
The Boston Wyoming Smelter Site was the site of a copper smelter that processed ores from the nearby Grand Encampment Mining District in Carbon County, Wyoming in the early 20th century. The site includes the former town of Rudefeha and is near Encampment, Wyoming. The smelter was constructed in 1902 by Grand Encampment promoter Willis George Emerson, connected to the main Ferris-Haggerty Mine location by a 16-mile (26 km) aerial tram over the Continental Divide. The smelter initially produced matte, an intermediate product in copper refining. In 1903 it was upgraded to produce blister copper. Power for the blowers needed for the blister refining process came from a water turbine at the end of a 4-foot (1.2 m) diameter wood-stave pipe from the South Fork of the Encampment River, 4 miles (6.4 km) away. The smelter could process 300 to 400 tons of ore a day.
