History

The Klondike Gold Rush was a turning event in the Yukon’s history. A party led by Skookum Jim Mason discovered gold in Bonanza Creek, a tributary of the Klondike River, in August 1896. An estimated 30,000 to 40,000 people braved numerous hardships to reach the Klondike gold fields in the winter and spring of 1897-1898 after the discovery became known in 1897.

The Keno Hill Camp was one of the great mining camps of Canada; it was not only Canada’s second largest primary silver producer and one of the richest Ag-Pb-Zn vein deposits ever mined in the world, it was also one of the mainstays of the Yukon economy from the 1920s, after the rapid decline of the Klondike Goldfield, until the early 1960s. At its peak in the 1950s and early 1960s, it supported about 15% of the territorial population. It also produced more wealth than the Klondike. Following a small amount of hand mining between 1913 and 1917, larger scale production was almost continuous from 1919 to 1989, except during the war from 1942 to 1945. Two companies produced most of the ore, Treadwell Yukon Corp. Ltd. from 1925 to 1941, and United Keno Hill Mines Ltd. between 1947 and 1989. Both companies went bankrupt when silver prices failed to increase as quickly as mining costs. About three years of uneconomic ‘reserves’ remained at closure.

Total Ag production from the Keno Hill Camp was 214.04 million oz. from 4847 million tonnes of ore from 38 mines.

The Faro mine was opened in 1969. From the late 1960s until 1982 the mine became one of the largest lead-zinc mines in the world. At one time it was the largest open-pit mine in the world. During its history, 320 million tonnes of waste rock was removed to access the ore. The mine remained in more-or-less constant production until 1982.

An 18-month waste-rock stripping program was operated at the Faro mine in 1983 and 1984. Curragh Resources purchased the property in 1985 and production resumed in 1986. This operation ended in 1993. A third operation, by the Anvil Range Mining Corporation, opened in 1995 and ceased production in January 1998.

Total production from the Faro mine was 3.97 billion pounds of lead, 5.89 billion pounds of zinc and 52 million ounces of silver.

Mining declined in the Yukon during the 1980s and 1990s except for two mines.

The Whitehorse Copper mine produced 51 million pounds of copper, 3 million ounces of silver and 250,000 ounces of gold between 1967 and 1982.

The Brewery Creek mine produced 277,000 ounces of gold over its short mine life from 1996 to 2000.

The Yukon continues to attract significant exploration and development dollars with several projects at an advanced development stage.

Geology

Yukon is located in the northern part of the North American Cordillera, the mountainous backbone of the western part of the continent. Like most of the Cordillera, Yukon is composed of rocks that record more than a billion years of Earth history. These document the evolution of the western margin of Ancestral North America (Laurentia) and of the various displaced terranes that were accreted to it since late Paleozoic.

The northwest-striking Tintina fault is one of the most prominent physiographic and geologic features in the Yukon. It is a dextral strike-slip fault with about 430 km of Paleogene displacement. It generally separates rocks of Ancestral North American affinity to the northeast from those of the allochthonous Intermontane terranes to the southwest; except in southeast Yukon, where the Tintina fault has shuffled this order and the allochthonous Yukon-Tanana and Slide Mountain terranes lie northeast of the fault, and parautochthonous rocks of Cassiar terrane underlie the Pelly Mountains to the southwest.

The Intermontane terranes are mainly comprised of magmatic arc rocks and related sedimentary deposits that fringed western Laurentia between mid-Paleozoic and early Mesozoic. They envelop more exotic oceanic rocks of Cache Creek terrane in south-central Yukon, which includes elements of Tethyan affinity. The Intermontane terranes are bounded to the southwest by the northwest-striking Denali fault, an active dextral strike-slip fault with more than 400 km of displacement, that separates them from the Insular terranes. The Insular terranes consist of continental fragments and volcanic arc rocks that contain exotic elements of Baltican and Siberian affinities.

In northern Yukon, structures along the northeast-striking Porcupine lineament juxtapose rocks of the Ancestral North American margin with those of the Arctic-Alaska terrane to the northwest. Arctic Alaska is a composite terrane which includes Neoproterozoic and Paleozoic elements of Baltican-Siberian affinities, as well as less exotic northern Laurentian rocks.

Cretaceous and younger, mainly post-accretionary plutonic suites intrude part of the Laurentian margin strata and the Intermontane and Insular terranes in southern Yukon. These represent a succession of continental magmatic arcs and related back-arc environments that record the Cretaceous-Paleogene convergence of the various terranes.

The various terranes and plutonic suites that make up Yukon geology are host to a wide range of base and precious metal deposits. Successor basins that developed during Jurassic to Paleogene terrane convergence in the northern Cordillera have hydrocarbon potential.
