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.
Pitt Lake's Lost Gold Mine is a legendary lost mine said to be near Pitt Lake, British Columbia, Canada, the supposed wealth of which has held the imagination of people worldwide for more than a century.

One of the most famous lost mines in California is known as the Lost Dutch Oven mine.
 There are several versions of the story, as is the case with most lost mine legends, perhaps the best known is the one with Tom Schofield, a railroad worker, decided to do some prospecting in his time off.
 According to this version, while prospecting in the Clipper Mountains, northwest of Essex (in San Bernardino county), he found an old stone house.
 As the house appeared to be long abandoned, he continued on.
 Several miles further in his travels he found a spring.
 Near the spring he spotted an old trail.
 Following the trail, it led him up over a hill where he spotted a huge boulder that was split in two.
 The path went through this split boulder, and into what he believed was an ancient Spanish camp.
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 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.
Jolly Creek is a creek located in the Boundary Country region of British Columbia.
 The creek is south of Conkle Lake.

The National Mine Map Repository (NMMR) is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM).
 The NMMR resides in the Pittsburgh suburb of Green Tree, Pennsylvania, and collects and maintains mine map information and images for the entire country, including data and maps of coal mines in the anthracite coal region of northeastern Pennsylvania.
 The Green Tree facility provides and stores, digitally and in microfilm (aperture cards), over 182,000 maps of abandoned mines.
 This repository contains maps of mine workings from the 1790s to the present day.
 It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the United States.
 It also serves as a location to retrieve mine maps in an emergency.
 The NMMR provides services ranging from retrieving mine related data for economic analysis to assessing the potential risk associated with underground mining.
 Through analysis of mine maps and related information, the repository assists private and public sectors in industrial and commercial development, highway construction, and the preservation of public health, safety, and welfare.
 In addition, they collect, reproduce, and maintain a national inventory of mine maps and supporting documentation for private and public interests.
