The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith. These cherty iron ore deposits are Precambrian in the Vermilion Range and middle Precambrian in the Mesabi and Cuyuna ranges, all in Minnesota. The Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan have similar characteristics and are of similar age. Natural ores and concentrates were produced from 1848 until the mid-1950s, when taconites and jaspers were concentrated and pelletized, and started to become the major source of iron production.
Adams Mine is an abandoned open pit iron ore mine located in the Boston Township of the District of Timiskaming, 11 km (6.8 mi) south of Kirkland Lake in the Canadian province of Ontario. It is situated on the Canadian Shield.
Temagami, formerly spelled Timagami, is a municipality in northeastern Ontario, Canada, in the Nipissing District with Lake Temagami at its heart.
The Kanichee Mine, also less commonly known as the Ajax Mine, is an abandoned base metal and precious metal mine, located in the Temagami region of northeastern Ontario, Canada. It is near the small unincorporated community of Temagami North, accessed by the Kanichee Mine Road from Highway 11. The Kanichee Mine zone has been explored and mined discontinuously from as early as 1910. During the 20th century, it operated and closed down at least three times, with the most recent being from 1973 to 1976. To date, the discontinuous operation of Kanichee Mine has produced 4.2 million pounds of metal.
The Temagami Greenstone Belt (TGB) is a small 2.7 billion year old greenstone belt in the Temagami region of Northeastern Ontario, Canada. It represents a feature of the Superior craton, an ancient and stable part of the Earth's lithosphere that forms the core of the North American continent and Canadian Shield. The belt is composed of metamorphosed volcanic rocks that range in composition from basalt to rhyolite. These form the east-northeast trend of the belt and are overlain by metamorphosed sedimentary rocks. They were created during several volcanic episodes involving a variety of eruptive styles ranging from passive lava eruptions to viscous explosive eruptions.
The Gogebic Range is an elongated area of iron ore deposits located within a range of hills in northern Michigan and Wisconsin just south of Lake Superior. It extends from Lake Namakagon in Wisconsin eastward to Lake Gogebic in Michigan, or almost 80 miles. Though long, it is only about a half mile wide and forms a crescent concave to the southeast. The Gogebic Range includes the communities of Ironwood in Michigan, plus Mellen and Hurley in Wisconsin.
Beanland Mine, also known as Clenor Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 1 km (0.62 mi) west of Arsenic Lake and 4 km (2.5 mi) northwest of the town of Temagami in central Strathy Township. It is named after Sydney Beanland, who first claimed the mine site in the 1920s and was a director for the mine from 1937 to 1938.
The Northland Pyrite Mine, also known as James Lake Mine, Rib Lake Mine, Harris Mine or simply Northland Mine, is an abandoned underground mine in Northeastern Ontario, Canada, located on the southwestern shore of James Lake in Best Township of Temagami. It was operated by the Northland Mining Company during the early 1900s with the construction of a 91 m (299 ft) shaft and many open-cuts north of the shaft. Minerals present at the mine include chalcopyrite, pyrite and pyrrhotite, deposited in Precambrian volcanic rock of the Canadian Shield.
Barton Mine, also known as Net Lake Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 0.50 km (0.31 mi) north of the Temagami Arena in Temagami North and just east of the Ontario Northland Railway in northwestern Strathy Township. Dating back to the early 1900s, it is one of the oldest mines in Temagami. Barton was the site of a fire in the early 1900s, after which it never had active mining again.
The Milne Townsite, commonly referred to as Milnes, is an abandoned community in Strathy Township, municipality of Temagami, Nipissing District in northeastern Ontario, Canada, located on the north shore of Link Lake, just south of the Milne-Sherman Road, and about 2 km (1.2 mi) north of the town of Temagami. It covered about 3.5% of the town of Temagami and had 40 residents.
Big Dan Mine is an abandoned underground mine in Northeastern Ontario, Canada. It is located about 1 km (0.62 mi) southwest of Net Lake and just west of the Ontario Northland Railway in east-central Strathy Township. It is named after Dan O'Connor, who first claimed the site in the 1890s.
Tetapaga Lake, also known as Lake Tetapaga, is a narrow east–west trending lake in the Temagami region of Northeastern Ontario, Canada, located at the abandoned iron-bearing Sherman Mine. A gravel road crosses the central portion of the lake, splitting it into two small lakes. The eastern half of Tetapaga Lake is somewhat green in colour due to acid mine drainage water flowing into the lake. The acid mine drainage water results from water seeping through the abandoned iron ore of Sherman Mine along its eastern shore. Its western half is relatively uninfected where very little waste from Sherman Mine exists.
Coppersand Mine is an abandoned copper mine in Temagami, Northeastern Ontario, Canada. It is located near the eastern shore of Ferguson Bay of Lake Temagami. A winter road from Sandy Inlet through Coppersand Lake was created to the mine in 1957. Subsequently, a small road, known as Miner's Road, was constructed off Kokoko Sideroad in 1970 to access the mine. Mining from the late 1950s to 1970s resulted in the creation of a small open pit.
Steep Rock Lake is a body of water near the township of Atikokan, northern Ontario, Canada. It was originally fed by the Seine River.
O'Connor Mine, also known as Milestone Mine, is an abandoned surface mine in Northeastern Ontario, Canada. It is located about 1 km (0.62 mi) southwest of the town of Temagami near the Northeast Arm of Lake Temagami in northern Strathcona Township. It is named after John O'Connor who first developed the mine site.
Priest Mine is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 19 km (12 mi) northwest of the hamlet of Marten River on an island in north-central Cross Lake. Dating back to the early 1900s, it is one of the oldest mines in the municipality of Temagami.
The Northeast Arm Iron Range, also called the Temagami Iron Range, is an elongated area of iron ore in Nipissing District of Northeastern Ontario, Canada. It parallels the western side of Lake Temagami's Northeast Arm near the village of Temagami at its northern end. One of many small iron ranges in the Temagami area, the Northeast Arm Range consists of alternating bands of iron-rich and iron-poor sediments. It was discovered in the 1890s and has since seen sporadic mining and mineral exploration activities.
Vermilion Lake, sometimes incorrectly spelled Vermillion Lake, was a natural lake located 5 km (3.1 mi) northwest of the village of Temagami in Nipissing District, Ontario, Canada. It occupied the southwestern corner of geographic Strathy Township until it was dewatered in 1967 to provide initial tailings storage for the then developing Sherman Mine.
