Question: Discovery Mine and Northland Pyrite Mine, are both mines in which country?

 It was operated by the Northland Mining Company during the early 1900s with the construction of a 91 m shaft and many open-cuts north of the shaft. 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.  Minerals present at the mine include chalcopyrite, pyrite and pyrrhotite, deposited in Precambrian volcanic rock of the Canadian Shield. <SEP>  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 Discovery Mine was a gold mine 81 kilometers northeast (approx bearing of 15 degrees) of Yellowknife, Northwest Territories that operated between 1950 and 1969.  The abandoned townsite, not accessible by road, was demolished in 2005. <SEP> 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. <SEP> 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.
