Which of the two mines, Discovery Mine or Big Dan Mine, produced more gold?
Discovery Mine
Title: Colomac Mine
Passage: 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.
Title: USS Saranac (1899)
Passage: The third USS "Saranac was the Old Dominion Steamship Company Hamilton" temporarily converted for planting the World War I North Sea Mine Barrage.  John Roach & Sons launched "Hamilton" at Chester, Pennsylvania in 1899.  "Hamilton" steamed between Norfolk, Virginia and New York City until The United States Shipping Board took control of the ship from Old Dominion Steamship Company in 1917.  She was fitted out for United States Navy service by James Shewan & Sons at Brooklyn, New York.  The minelaying conversion enabled her to carry mines on two decks, and included four Otis elevators individually capable of transferring two mines every 20 seconds from the storage deck to the launching deck.  USS "Saranac" was commissioned on 9 April 1918 with Captain Sinclair Gannon, USN, in command.  While operating as part of Mine Squadron 1 out of Inverness, Scotland, from 14 July until the close of the war on 11 November 1918, "Saranac" laid a total of 4,782 mines:
Title: Agnew Gold Mine
Passage: The Agnew Gold Mine, formerly the Emu Mine, is a gold mine located 3 km west of Agnew, Western Australia.  It is owned by the South African mining company Gold Fields.  It is one of two mines the company operates in Australia, the other being the St Ives Gold Mine.
Title: Big Dan Mine
Passage: Big Dan Mine is an abandoned underground mine in Northeastern Ontario, Canada.  It is located about 1 km 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.
Title: Calhoun Mine
Passage: The Calhoun Mine is perhaps the oldest and best-known mine in Lumpkin County, Georgia.  When gold was discovered in Lumpkin County in 1828, which led to the Georgia Gold Rush in 1829, it was discovered on 239 acre owned by Robert Obar.  After at least two intermediary sales, the land was purchased by Senator John C. Calhoun of South Carolina, who was also the 7th Vice President of the United States.  Calhoun started a mining company to mine the land and later allowed his son-in-law Thomas Green Clemson, the founder of Clemson University, to manage it.  The ore deposit was a very rich deposit and, according to an 1856 letter from Clemson to his brother-in-law, was still producing significant quantities of gold nearly 30 years after its initial discovery on the land.  This mine - along with the Consolidated Mine and the Loud Mine - were some of the most productive mines in the Georgia Gold Belt.
Title: Crisson Mine
Passage: Crisson Mine was a gold mine in Lumpkin County, Georgia, USA, located just east of Dahlonega.  Like many mines in the area, the property probably started as a placer mine during the Georgia Gold Rush.  Once the placer deposits had been exhausted, an open pit gold mine was established in 1847 and commercial operations continued until the early 1980s.  A small stamp mill was also established here.  Much of the gold used for the gold leaf dome of the Georgia State Capitol was mined at this mine, which was among the most productive mine in the Georgia Gold Belt.  The mine is located just north of the site of the Consolidated Mine, which is itself north of and the Calhoun Mine.
Title: Pinacate Mining District
Passage: The Pinacate Mining District is a five to eight miles southwest of Perris, California.  It included the Good Hope Mine, Steele's Mine, Santa Rosa (Rosalia) Mine, Virginia or Shay Mine, Santa Fe Mine and many other smaller works like the Little Maggie Mine.  It produced a total of about 104,000 ounces of gold through 1959, all from the lodes of various mines.  Although the district declined until the mid-1930s when attempts were made to rehabilitate the Good Hope and several other mines.  These efforts were largely unsuccessful, the Good Hope mine closed when it was flooded with underground water.  Only 3 ounces of gold were produced in the district between 1943-59.
Title: Leckie Mine
Passage: Leckie Mine, also known as Penrose Mine and Little Dan Mine, is an abandoned gold producing underground mine in Northeastern Ontario, Canada, located on the eastern shore of Arsenic Lake 4 km north of the town of Temagami.  It is entirely owned by Temagami Gold Inc.  An estimated 483,500 tonnes of ore remain in the mine, which could contain 102,720 ounces of gold.
Title: P3 Mk2 mine
Passage: The P2 Mk2 and P3 Mk2 are Pakistani plastic cased minimum metal anti-tank blast mines.  The P2 Mk2 has a square case with a central circular ribbed pressure plate, the P3 is circular with a central circular pressure plate.  Both mines use anti-personnel mines as the fuse, typically the either the P4 Mk1 or P2 Mk2 anti-personnel mines.  The anti-personnel mine sits in a cavity below the pressure plate, when enough pressure is place on the pressure plate of the mine, it collapses onto the anti-personnel mine triggering it and the main charge which sits below it.  A yellow canvas carrying strap is normally fitted to the side of the mine.  The mines have a secondary fuse well on the bottom which can be used with anti-handling devices.  A GLM-2 electronic booby trap can be fitted to the cavity under the pressure plate.  The mine is supplied with a steel disc which makes the mine more easily detectable, although this is seldom used.  Since 1997 only a detectable version of the mine has been produced, and to comply with the Convention on Conventional Weapons amended protocol II, Pakistani stocks of the mine are being retrofitted with steel detection discs.  The mines are found in Afghanistan, Angola, Eritrea, Ethiopia, Pakistan, Somalia, and Tajikistan.
Title: Discovery Mine
Passage: The Discovery Mine was a gold mine 81 kilometers northeast (approx bearing of 15 degrees) of Yellowknife, Northwest Territories that operated between 1950 and 1969.  Gold was discovered here by Alfred Giauque in 1944.  A complete townsite, on Giauque Lake, was established by the company to house workers and their families.  The mine produced one million troy ounces (31,000 kg) of gold from one million tons of ore.  The abandoned townsite, not accessible by road, was demolished in 2005.
