Context paragraphs:
Sustut Peak: Sustut Peak, 2481 m (8140 ft), prominence: 1231 m, is the highest summit in the drainage of the Sustut River in British Columbia, Canada.  Located in the Hogem Ranges west of Sustut Lake, which is at the Sustut River's headwaters, it is 8 km southwest of the road to the Kemess Mine

Lost Lemon Mine: The Lost Lemon Mine is a legendary lost mine said to be located in the Canadian Province of Alberta.  The story has been retold in countless books with the authoritative version being "The Lost Lemon Mine" by Tom Primrose.The story first appeared in the 1946 edition of the "Alberta Folklore Quarterly" and later in magazines such as "Canada West".  The Lost Lemon Mine has also been featured in television documentary series "Northern Mysteries", and worked into the plot of "The Final Sacrifice".  Countless people have searched for the mine.  A number of searchers have never returned.

Ptarmigan and Tom Mine: The Ptarmigan and Tom Mine were gold producers located in the Northwest Territories, Canada at Yellowknife.  The property was staked by prospectors in 1936 and acquired by Cominco in 1938.  The mine first produced between 1941 and 1942 but closed due to wartime restrictions.  The old property was demolished in 1969–1970.  A new company, Treminco Resources Limited, reopened the workings in 1985 and production from the Tom ( ) portal began in 1986 with material being trucked to Giant Mine.  The old Ptarmigan ( ) mine shaft was dewatered and production began in 1987.  A new mill was built at the property and was operational in July 1989.  Low gold prices forced the company to close the mines in 1997.  Total gold production has been approximately 120,000 troy ounces (3700 kg).

Cascadero Falls: Cascadero Falls is a waterfall on the Finlay River in the Northern Interior of British Columbia, Canada, located just below that river's head at the outlet of Thutade Lake.  The height of the falls is 180 ft and below it there are numerous cascades or rapids in a twisting course prior to the river's general northeastward trend from this area.  The falls are slated for hydroelectric development in connection with the area's mines, the largest of which is the Kemess Mine owned by Northgate Minerals Inc., located just east of the foot of Thutade Lake in the valley of Kemess Creek.

Kemess Mine: The Kemess Mine was an open-pit copper and gold mine, located just northeast of the foot of Thutade Lake, at the head of the Finlay River, in the Omineca Mountains of the Northern Interior of British Columbia, Canada.  It was operated by Royal Oak Mines from 1998 to 1999, when it was bought by Northgate Minerals.  Northgate operated the mine until its closure in 2011; that year Northgate was taken over by AuRico Gold.  In 2014 AuRico Gold partitioned off its portion of kemess Mine ownership creating a new company called AuRico Metals.  AuRico Metals is actively implementing permits for a block caving mine.

Victor Diamond Mine: The Victor Diamond Mine is the first Canadian diamond mine located in Ontario, and De Beers' second diamond mine in Canada (after the Snap Lake Diamond Mine).  It is located in the Northern Ontario Ring of Fire, in the James Bay Lowlands 90 km west of Attawapiskat in the remote northern part of the province.  In June 2005, the Attawapiskat First Nation voted in favour (85.5%) of ratifying the Impact Benefit Agreement (IBA).  Construction of the mine began in February 2006 which created 3200 positions; mining and operations will create around 400 permanent positions.  The Victor Mine is an open-pit mine, with a processing plant, workshops, and an airstrip located on site.  By 2013-2014 royalties collected from De Beers Victor Diamond Mine amounted to $226.  At that time De Beers was continuing to pay off its "$1 billion investment to build the mine and from now until it closes, the company expects to pay tens of millions of dollars in royalties."

Thutade Lake: Thutade Lake is located in the Omineca Mountains of the Northern Interior of British Columbia, Canada.  About 40 km in length, and no more than about 2 km wide, the lake is primarily significant as the ultimate source of the Mackenzie River.  The lake is at the head of the Finlay River, which joins the Peace River via Williston Lake.  The area is very remote, being located about 260 km north of Smithers, although several mining operations for ores containing copper, lead, zinc and silver have occurred around the lake.  The largest of these is the Kemess Mine, an iron and copper property originally owned by Royal Oak Mines and now by Northgate Minerals, located in the valley of Kemess Creek, which is off the northeast end of Thutade Lake.  The mine is accessed by the Omineca Resource Road and other resource routes, and is 400 km by road from Prince George.  Just downstream from the outlet of Thutade Lake, the Finlay plunges over 180 ft Cascadero Falls, and then through a series of cataracts in a twisting course until it begins its main northeastward trend.  Cascadero Falls is slated for hydroelectric development in connection with the power needs of the area's mines.

Kemess Creek Airport: Kemess Creek Airport, (TC LID: CBQ7) , is located near Kemess Mine, British Columbia, Canada.

Colomac Mine: The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada .  The Colomac mine operated between 1990–1992, and 1994–1997.  It was operated by Neptune Resources Limited that had little success in making a profit during its operation.  In 1994, the mine had reopened under Royal Oak Mines Inc.  Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte.  Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy.  The Federal Government of Canada became owners of the mine, along with the related environmental issues.  A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage.  This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority.

Husab Mine: The Husab Mine, also known as the Husab Uranium Project, is a uranium mine under development near the town of Swakopmund in the Erongo region of western-central Namibia.  The mine is located approximately 60 km from Walvis Bay.  The Husab Mine is expected to be the second largest uranium mine in the world after the McArthur River uranium mine in northern Saskatchewan, Canada and the largest open-pit mine on the African continent.  The Husab Mine is to start production in early December 2015 after completion of the sulfuric acid leaching plant.
