The Kiruna mine is the largest and most modern underground iron ore mine in the world.
 The mine is located in Kiruna in Norrbotten County, Lapland.
 The mine which is owned by Luossavaara-Kiirunavaara AB, a large Swedish mining company, has an annual production capacity of over 26 million tonnes of iron ore.
 In 2008 the mine produced 27.5 million tonnes of iron ore.
 The Kiruna mine has an ore body which is 4 km long, 80 m to 120 m thick and reaching a depth of up to 2 km .
 Since mining began at the site in 1898, the mine has produced over 950 million tonnes of ore.
The Tundra Mines was a gold producer in the Northwest Territories, Canada between 1964 and 1968, producing 104,476 troy ounces (3250 kg) of gold from 187,714 tons of ore.
 A detailed history is provided in the link below.
 Indian and Northern Affairs Canada has a project to remediate the Tundra Mine site under their Northern Contaminants Program, funded by the Canadian Federal Contaminated Sites Action Plan.
Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada.
 The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body.
 Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold.
 It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada.
 A mill was not initially needed because the ore was 28% copper.
 The mine closed in 1972 and is now flooded by water.
 Ruins of the Copperfields mill are present as foundations.
 It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others.
 The Lake Temagami Access Road was created to ship ore from the mine site.
The Salmita Mine was a gold producer in the Northwest Territories, Canada during 1983 to 1987.
 The deposit was first discovered in 1945 and underground exploration was carried out in 1951-1952.
 It was reactivated for exploration by Giant Yellowknife Mines Limited in 1975 and entered production in 1983.
 They used the old camp and milling plant of the abandoned Tundra Mine, located a few kilometres to the south.
 The mine produced 179,906 troy ounces (5596 kg) of gold from the milling of 238,177 tons of ore.
Kivimaa mine was gold and copper mine active during the years 1969-1970 in Tervola at Sivakkajoki.
 During this time 18 587 tonnes of ore were extracted which contained 2.0 grams of gold per tonne.
 The concentration of copper in the ore was 1,20%.
 Outokumpu Ltd.
, which owned the mine, mined the quartz-carbonate veins with highest concentration of gold and copper.
 The ore from the mine was transported to the mine of Vihanti to be enriched.
 The mining ended on the 12th of December 1969.
 The buildings at the mine were taken down in the summer of 1974.
The Ferris-Haggerty Mine Site was one of the richest components of the Grand Encampment Mining District in Carbon County, Wyoming.
 The site was first exploited by Ed Haggerty, a prospector from Whitehaven, England, in 1897 when he established the Rudefeha Mine on a rich deposit of copper ore.
 Haggerty was backed by George Ferris and other investors, of whom all but Ferris dropped out.
 The partners sold an interest to Willis George Emerson, who raised investment funding for improvements to the mine.
 These facilities included a 16 mi aerial tramway from Grand Encampment over the Continental Divide to the in Encampment.
 The mine's assets were eventually acquired by the North American Copper Company for $1 million.
 By 1904 the mine had produced $1.4 million in copper ore, and was sold to the Penn-Wyoming Copper Company.
 However, even with copper prices peaking in 1907, the company had difficulty making a profit from the remote mine site.
 The company was over-capitalized and under-insured and was suffered devastating fires at the mine site in March 1906 and May 1907 which halted production.
 Business disputes and a fall in copper prices prevented re-opening of the mine even after it was rebuilt.
 Machinery was salvaged after a foreclosure in 1913.
 A total of $2 million in copper ore was extracted from the mine during its life.
The Outpost Island Mine was a gold and tungsten producer 94 kilometres southeast of Yellowknife, Northwest Territories on an island of Great Slave Lake.
 Gold was discovered here in 1935 by prospectors, and some development was undertaken in 1936-1938.
 Tungsten ores became valuable during World War II, so the owners (Slave Lake Gold Mines Limited) investigated the tungsten possibilities of the mine.
 It produced small amounts of gold, copper, and tungsten during 1941-1942, and then again in 1951-1952 during the Korean War.
 It was a small deposit and was not considered economic because of unpredictable tungsten market prices in the 1950s.
The Malmberget mine (Swedish: "Malmbergsgruvan") is one of the largest iron ore mines in Sweden.
 The mine is located in Malmberget in Norrbotten County, Lapland.
 The mine which is owned by Luossavaara-Kiirunavaara AB (LKAB) has an annual production capacity of over 5 million tonnes of iron ore.
 The mine has reserves amounting to 350 million tonnes of ore grading 43.8% iron thus resulting 153.3 million tonnes of iron.
 In 2009 the mine produced 4.3 million tonnes of iron.
 It is one of the largest underground mines for iron ore in the world.
Tundra Mine/Salamita Mine Aerodrome (TC LID: CTM7) is a registered aerodrome that served the Tundra and Salamita Mines in the Northwest Territories, Canada.
The Gag Island mine is a large mine in the east of Indonesia in Sulawesi.
 Gag Island represents one of the largest nickel reserve in Indonesia having estimated reserves of 240 million tonnes of ore grading 1.35% nickel.
 The 240 million tonnes of ore contains 3.24 million tonnes of nickel metal.

Question: Which produced more types of ore, Outpost Island Mine or Tundra Mine?
Answer: Outpost Island Mine
