Ott's Assay Office Ott's Assay Office is a historic assay office located at 130 Main Street in Nevada City, California. The building was constructed in 1851 as a drug store; James J. Ott opened his assay office in the back of the store in 1857. In 1859, Ott assayed a sample of silver ore discovered in the Washoe Country; this ore marked the discovery of the Comstock Lode, and the resulting silver rush eventually led to Nevada's statehood and several advancements in mining technology. The silver rush also gave Ott a reputation as a quality assayer; he ran his office until his death in 1907, and his son continued the business until 1955.

Cannington Mine The Cannington Silver and Lead Mine is an Australian underground mine located in north-west Queensland, in the Shire of McKinlay, about 200 km southeast of Mount Isa. The deposit was discovered by Broken Hill Proprietary Company (BHP) in 1990. Although sitework and underground mining began in 1997, full production was not achieved until early 1999, with 1.5 million tons of ore processed in 1999. Production since has reached 3 million tons of ore per year. s of 2010 it was the largest and lowest cost silver and lead mine in the world. The expected life of the Cannington mine is 25 years. On August 19, 2014, the mine's owner BHP Billiton announced it was splitting the company in two. A newly formed entity called South32 is to house BHP Billiton's non-core businesses including the Cannington Mine. South32 is listed on the Australian Securities Exchange (under the code S32), with a secondary listing in Johannesburg.

International Smelting and Refining Company The International Smelting and Refining Company was a subsidiary of Anaconda Copper which operated primarily out of the International Smelter near Tooele, Utah. The International Smelter began operation in 1910 as a copper producer handling ores from Bingham Canyon and was expanded into a lead smelting operation in 1912. Copper smelting finished at International in 1946, and the lead smelter shut down in January 1972. The closure of the smelter would lead to the associated Tooele Valley Railway (which had their primary railyards at the smelter) to be shut down ten years later in 1982. The company also handled several other Anaconda owned interests. After the shut down of the International Smelter, environmental reclamation was performed by Anaconda Copper's successor company ARCO and the EPA Superfund program.

Adel Mountains Volcanic Field The Adel Mountains Volcanic Field (also known as the Adel Mountains, Adel Volcanics, and Adel Mountain Volcanics) is an ancient volcanic field of heavily eroded 75-million-year-old igneous rocks about 40 miles long and 20 miles wide (800 square miles, or 2,071 square kilometers) in west-central Montana about 30 miles southwest of the city of Great Falls. The area was named by geologist John Bartholomew Lyons, who first described the general geology of the region in 1944. The Adel Mountains Volcanic Field is a significant and abundant source of shonkinite, a very uncommon type of intrusive igneous rock found primarily in Montana, Ontario, and Timor. Because of its geologic structure, the Adel Mountains Volcanic Field has drawn the attention of geologists for more than 100 years.

Bathurst Mining Camp The Bathurst Mining Camp is a mining district in northeast New Brunswick, Canada, centred in the Nepisiguit River valley, and near to Bathurst. The camp hosts 45 known volcanogenic massive sulfide (VMS) deposits typical of the Appalachian Mountains. Some of the ore is smelted at the Belledune facility of Xstrata. Although the primary commodity is zinc, the massive-sulphide ore body produces lead, zinc, copper, silver, gold, bismuth, antimony and cadmium.

Silver King Camp Silver King Camp is a ghost town located in the West Kootenay region of British Columbia. The town is located on Toad Mountain near Nelson and was founded in the 1880s. In 1887 silver ore was discovered on Toad Mountain, and a mine was created called the Silver King which was owned by the Hall family of Nelson. A town grew around the workings of the mine. By 1898 Silver King Camp had a population of 190. The Silver King mine was the greatest shipper of silver ore to the Nelson Smelter for two decades. A forest fire destroyed Silver King Camp and today little remains of the town.

Cerro Rico Cerro Rico (Spanish for "rich mountain"), Cerro Potosí ("Potosí mountain") or Sumaq Urqu (Quechua "sumaq" beautiful, good, pleasant, "urqu" mountain, "beautiful (good or pleasant) mountain") is a mountain in the Andes near the Bolivian city of Potosí. Cerro Rico was famous for providing vast quantities of silver for Spain during the period of the New World Spanish Empire. The mountain, which is popularly conceived of as being "made of" silver ore, caused the city of Potosí to become one of the largest cities in the New World. After 1800, the silver mines were depleted, making tin the main product. This eventually led to a slow economic decline. Nevertheless, the mountain continues to be mined for silver to this day. Due to poor worker conditions, such as a lack of protective equipment against the constant inhalation of dust, many of the miners contract silicosis and have a life expectancy of around 40 years. The mountain is still a significant contributor to the city's economy, employing some 15,000 miners.

Hilton Mine The Hilton Mine is a zinc, lead and silver mine in northwestern Queensland, Australia, approximately 22 km north of the Mount Isa Mines. The mineralization is in the same grey dolomitic Urquhart Shale as the Mount Isa Mines deposit and a similar diagenesis is posited. It is one of five "supergiant" zinc, lead and silver mineralized deposits that have been found in the Mount Isa Inlier, six if one counts the high silver deposit at Cannington.

Mount Prindle Mount Prindle is a granitic mountain in the Yukon-Tanana Uplands, and is located approximately 45 mi north-northeast of Fairbanks, Alaska. The plutons that form the core of the Mount Prindle massif are Late Cretaceous or early Tertiary age. These plutons intruded older (Precambrian to Paleozoic) metamorphic rocks. Mount Prindle exhibits classic glacial landforms, unlike most of the surrounding Yukon-Tanana Uplands. It is in the Circle Mining District and many of the surrounding creeks have been or are being mined for placer gold. The area has also been prospected for tin and rare earth minerals. Mine roads and hiking trails provide access to the mountain. A 900 ft granite wall on an eastern spur of the massif is an attraction for rock climbers.

Cariboo The Cariboo is an intermontane region of British Columbia along a plateau stretching from the Fraser Canyon to the Cariboo Mountains. The name is a reference to the caribou that were once abundant in the region. The Cariboo was the first region of the Interior north of the lower Fraser and its canyon to be settled by non-indigenous people, and played an important part in the early history of the colony and province. The boundaries of the Cariboo proper in its historical sense are debatable, but its original meaning was the region north of the forks of the Quesnel River and the low mountainous basins between the mouth of that river on the Fraser at the city of Quesnel and the northward end of the Cariboo Mountains - an area that is mostly in the Quesnel Highland and focused on several now-famous gold-bearing creeks near the head of the Willow River, the richest of them all, Williams Creek, the location of Barkerville, which was the capital of the Cariboo Gold Rush and also of government officialdom for decades afterwards (it is now a museum town). This area, the Cariboo goldfields, is underpopulated today but was once the most settled and most powerful of the regions of the province's Interior. As settlement spread southwards of this area, flanking the route of the Cariboo Road and spreading out through the rolling plateaus and benchlands of the Cariboo Plateau and lands adjoining it along the Fraser and Thompson, the meaning changed to include a wider area than the goldfields.
