Which of the following abandoned mines still have ore in them, Leckie Mine or Temagami-Lorrain Mine?
Leckie Mine
Title: Abandoned Mines Information System
Passage: The Abandoned Mines Information System (AMIS) is a database created by the Ministry of Northern Development and Mines of Ontario, Canada.  It includes over 5,600 abandoned and inactive mines throughout Ontario, as well as associated hazards.  Basic information about every known abandoned and inactive mine in Ontario is in the database, including name, location and period when it was in operation.
Title: Mine exploration
Passage: Mine exploration is a hobby in which people visit abandoned mines, quarries, and sometimes operational mines.  Enthusiasts usually engage in such activities for the purpose of exploration and documentation, sometimes through the use of surveying and photography.  In this respect, mine exploration might be considered a type of amateur industrial archaeology.  In many ways, however, it is closer to caving, with many participants actively interested in exploring both mines and caves. Mine exploration typically requires equipment such as helmets, head lamps, Wellington boots, and climbing gear.
Title: Copperfields Mine
Passage: 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.
Title: Temagami-Lorrain Mine
Passage: Temagami-Lorrain Mine is an abandoned surface and underground mine in Northeastern Ontario, Canada.  It is located about 10 km northeast of the town of Temagami near Sauvé Lake in central Cassels Township.  It is named after the Temagami-Lorrain Mining Company, which carried out work on the property in the early 1900s.
Title: Malmberget mine
Passage: 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.
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: Jackson Mine
Passage: The Jackson Mine is an open pit iron mine in Negaunee, Michigan, extracting resources from the Marquette Iron Range.  The first iron mine in the Lake Superior region, Jackson Mine was designated as a Michigan State Historic Site in 1956 and listed on the National Register of Historic Places in 1971.  The Lake Superior Mining Institute said, the mine "is attractive in the iron ore region of Michigan and the entire Lake Superior region, because of the fact it was here that the first discovery of iron ore was made, here the first mining was done, and from its ore the first iron was manufactured."  Multiple other mines soon followed the Jackson's lead, establishing the foundation of the economy of the entire region.  The mine is located northwest of intersection of Business M-28 and Cornish Town Road.
Title: Emmer Green (Hanover) Chalk Mine
Passage: The Emmer Green (Hanover) Chalk Mine is an extensive abandoned subterranean chalk mine at Emmer Green, north of Reading in Berkshire, located just north of the junction of Peppard Road & Kiln Lane (OS Grid Ref: SU722769).  The mine is so named because the land is now owned by the Hanover Housing Association who have a development adjacent at Wordsworth Court.  The mine is one of a number of known mines in the Emmer Green and Reading area where chalk mining was often done in conjunction with brick making as chalk and clay are found together in the area and chalk was use in the making of bricks.  It is likely other abandoned mines remain undiscovered.  The area was once known as Rose Hill and contained brickfield and chalk mining works.
Title: Cerro Gordo Mines
Passage: The Cerro Gordo Mines are a collection of abandoned mines located in the Inyo Mountains, in Inyo County, California.  Mining operations were undertaken from 1866 until 1957, producing high grade silver, lead, and zinc ore.  Some ore was smelted on site, but larger capacity smelters were eventually constructed along the shore of nearby Owens Lake.  These smelting operations were the beginnings of the towns of Swansea and Keeler.  Most of the metal ingots produced here were transported to Los Angeles, but transportation difficulties hindered the success of the mines.  Mining of silver and lead peaked in the early 1880s, with a second mining boom producing zinc in the 1910s.
Title: National Mine Map Repository
Passage: 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.
