An adit or stulm is a horizontal or nearly horizontal passage to an underground mine. Miners can use adits for access, drainage, ventilation, and extracting minerals at the lowest convenient level. Adits are also used to explore for mineral veins. Although most strongly associated with mining, the term adit is sometimes also used in the context of underground excavation for non-mining purposes; for example, to refer to smaller underground passageways excavated for underground metro systems, to provide pedestrian access to stations, and for access required during construction.

The Purcell Mountains are a mountain range in southeastern British Columbia, Canada. They are a subrange of the Columbia Mountains, which includes the Selkirk, Monashee, and Cariboo Mountains. They are located on the west side of the Rocky Mountain Trench in the area of the Columbia Valley, and on the east side of the valley of Kootenay Lake and the Duncan River. The only large settlements in the mountains are the Panorama Ski Resort and Kicking Horse Resort, adjacent to the Columbia Valley towns of Invermere and Golden, though there are small settlements, such as Yahk and Moyie along the Crowsnest Highway, and residential rural areas dependent on the cities of Creston, Kimberley and Cranbrook, which are located adjacent to the range..
There are several classification systems for the economic evaluation of mineral deposits worldwide. The most commonly used schemes base on the International Reporting Template, developed by the CRIRSCO - Committee for Mineral Reserves International Reporting Standards, like the Australian Joint Ore Reserves Committee - JORC Code 2012, the Pan-European Reserves & Resources Reporting Committee' – PERC Reporting Standard from 2021, the Canadian Institute of Mining, Metallurgy and Petroleum - CIM classification and the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC). A more detailed description of the historical development concerning reporting about mineral deposits can be found on the PERC web site.
Hoodoo Mountain, sometimes referred to as Hoodoo Volcano, is a potentially active stratovolcano in the Northern Interior of British Columbia, Canada. It is located 25 kilometres northeast of the Alaska–British Columbia border on the north side of the Iskut River opposite of the mouth of the Craig River. With a summit elevation of 1,850 metres and a topographic prominence of 900 metres, Hoodoo Mountain is one of many prominent peaks within the Boundary Ranges of the Coast Mountains. Its flat-topped summit is covered by an ice cap more than 100 metres thick and at least 3 kilometres in diameter. Two valley glaciers surrounding the northwestern and northeastern sides of the mountain have retreated significantly over the last hundred years. They both originate from a large icefield to the north and are the sources of two meltwater streams. These streams flow along the western and eastern sides of the volcano before draining into the Iskut River.

Crystal Mountain Resort was a day-use ski area near West Kelowna, British Columbia, Canada. It operated two chairlifts and one surface lift: a GMD Mueller double chair, a Poma triple chair, and a Doppelmayr T-bar. The ski area had 30 designated groomed runs and the resort also featured many different tree trails and some glades. Despite the smaller size of the resort, which was considerably smaller than neighbouring resorts such as Big White Ski Resort and Silver Star Mountain Resort, the mountain was a good size and a popular destination for both experienced and first-time skiers, snowboarders and snowshoers. Despite the lower elevation, the area receives heavy snowfall each year with many powder days throughout the winter season. It was long known as Last Mountain Ski Resort but changed its name to Crystal Mountain Resort in 1992. Crystal Mountain Resort offered lessons for skiing and snowboarding and also offered rentals for snowshoeing. It has not been in operation since 2014 due to a lift malfunction of the red double chair.
The Sacred Headwaters is a large subalpine drainage basin centred around Klappan Mountain of the Klappan Range in northern British Columbia. It is the source of three wild salmon rivers: the Skeena River, Nass River, and Stikine River. It is also referred to as the Klappan Valley, although the Klappan—a tributary of the Stikine River—is only one of the area's watersheds. Local Tahltan people call the area Klabona, which is loosely translated as "headwaters".
The Mount Edziza Recreation Area was a recreation area in Cassiar Land District of northwestern British Columbia, Canada, located southeast of the community of Telegraph Creek. It was established on 27 February 1972 along with Mount Edziza Provincial Park. Initially, the 101,171-hectare (249,999-acre) recreation area formed a 1-to-10-kilometre-wide (0.62-to-6.21-mile) buffer zone around much of the provincial park.

Peggy-Kay Hamilton (1922–1959) was born in Illinois in 1922 and was an American Research Associate in Mineralogy in the Department of Geology at Columbia University. One of Hamilton's first research breakthroughs was developing Research Project 49, otherwise known as the study of clay minerals. In her later research years, her focus shifted and led to her becoming involved full time in the study of uranium.
Uranium mining around Bancroft, Ontario, was conducted at four sites, beginning in the early 1950s and concluding by 1982. Bancroft was one of two major uranium-producing areas in Ontario, and one of seven in Canada, all located along the edge of the Canadian Shield. In the context of mining, the "Bancroft area" includes Haliburton, Hastings, and Renfrew counties, and all areas between Minden and Lake Clear. Activity in the mid-1950s was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world".
