Monticello, Utah
In 1942, the U.S. government, through the Defense Plant Corporation (DPC), provided funding for a mill to be constructed at a uranium and vanadium ore-buying station that was built in 1940. The mill, created to produce vanadium and uranium for military purposes, was operated for DPC by the Vanadium Corporation of America (VCA) from 1942 into early 1944. VCA reopened the mill from 1945 to 1946 under lease from DPC. The U.S. Atomic Energy Commission (AEC), predecessor of the U.S. Department of Energy (DOE), obtained the mill in 1948, but it continued to be operated by private entities until ore milling was terminated in January 1960.
Approximately 900,000 tons of ore were processed at the mill. Mill tailings— predominantly sandy residue that contains low levels of radionuclides and metals that remain after ore is processed— were impounded at four locations adjacent to the
nearby Montezuma Creek.
Properties in Monticello and near the mill site were contaminated by windblown tailings, tailings carried by water in Montezuma Creek, and tailings that were used for construction-related purposes such as:
- fill for open lands, backfill around water, sewer, and electrical lines
- base for driveways, sidewalks, and concrete slabs, backfill against basement foundations
- sand mix in concrete, plaster, and mortar.
Photographed at the Battery Hill Mine Museum. Tennant Creek has a rich history as a gold mining centre. Here was found one of the richest gold bearing seams ever mined in the world. Very remotely located in central Australian desert country, life was harsh for the people who lived here.
Cornwall - St Agnes.
Mining.
Cornwall, along with its neighbouring county of Devon, was an important source of tin for Europe and the Mediterranean throughout ancient times, but began dominating the market during late Roman times in the 3rd century AD with the exhaustion of many Spanish tin mines. Cornwall maintained its importance as a source of tin throughout medieval times and into the modern period.
At their height about 100 mines employed 1000 miners. Mining came to an end in the 1920s and many of these mines are still on view for tourists. United Hills mine produced 86,500 tons of copper ore, 1826–1906; and Wheal Towan 54,610 tons, 1800-31. Lesser quantities of black tin were produced from these mines: West Wheal Kitty 10,070 tons (1881–1915); Wheal Kitty 9,510 tons (1853–1918); Polberro 4,300 tons (1837–95); Penhalls 3,610 tons (1834–96); and Blue Hills 2,120 tons (1858–97). Much of the Cornwall and West Devon Mining Landscape, a World Heritage Site, is in the parish. Tin production is still worked at the Blue Hills Tin Streams.
Wheal Coates was the site of medieval mining between 1066 and 1540, and it was a modern mining producer from 1802 and into the 20th century. The visible remains of Wheal Coates are the engine houses built in the 1870s to crush ore, run a Calciner, or pump water. The sites, owned by the National Trust, include the Whim Engine House, Towanroath Pumping Engine House and the Calciner. Before that the Jericho valley, where Blue Hills Tin Streams operated, had supported mining operations for centuries. At Chapel Coombe a set of old Cornish stamps has been re-erected by the Trevithick Society.

Granite Ghost Town in Summer, Granite County, Montana
Silver was first discovered in the area around Granite in 1865. The Granite mine, "Ruby Shaft," was discovered in 1872. During the course of silver mining at Granite, $40 million dollars worth of silver was removed, making it the "richest silver mine on earth." The mine was closed after the silver panic of 1893.
The site pictured is the east end of what remains of two massive buildings that covered the face of these rock walls and contained 70 stamp mills that crushed ore from the Ruby shaft. After crushing, the ore was sent down the hill for the silver to be separated from the base metal by amalgamation with mercury. The stamp mills worked six days a week at the height of production.These ruins and the ruins of the mining operation are located
Granite was a company town, built by the Granite Mountain Mining Company. It is located approximately four miles due north of present day Philipsburg, MT.
