Question: Which of these mines is more important to Canadian mining history, Hermiston-McCauley Mine or the McIntyre Mines?
Context: Karl Brooks Heisey (b.1895 Markham, Ontario d. 7 December 1937 Toronto, Ontario) was a well-known Canadian mining engineer and mining executive in the 1930s.  Heisey pioneered the exploration and development of the Sanshaw/Red Lake metal deposits located in northwest Ontario in the 1930s.  The Red Lake Mine is one of the richest gold mines in the world, still in production today with annual production of 600,000 ounces gold and over 11 million ounces produced to date. 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. 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. Hermiston-McCauley Mine is a large abandoned underground gold mine in Strathy Township of Temagami, Northeastern Ontario, Canada.  It is located between the southwestern arm of Net Lake and the south arm of Kanichee Lake. The Independence Mines, now Independence Mine State Historic Park, is the site of a former gold mining operation in the Talkeetna Mountains, across Hatcher Pass from Palmer, Alaska.  The area's mining history dates to at least 1897, when active claims were reported in the vicinity of Fishook Creek.  These early mining efforts were eventually joined to form the Wasilla Mining Company, which worked the mines from 1934 to 1943, and again from 1948 to 1950.  The mining operation at Independence was the second-largest hard-rock gold mining operation in the state, after a larger site near Juneau.  The company and the miners that preceded it built a substantial mining camp, with as many as sixteen wood frame buildings, which were originally connected to each other by sheltered wooden "tunnels".  When the company ended operations in 1950, it had expected to eventually resume operations, but never did; this resulted in a particularly well-preserved collection of mining equipment and buildings, although the weather has since taken a significant toll on the latter. Echo Bay Mines Limited is a Canadian company which was organized in 1964 by Northwest Explorers Limited to develop a silver deposit at Great Bear Lake, Northwest Territories, Canada, which had been staked in 1930 by The Canadian Mining and Smelting Company.  The company leased the old Port Radium settlement from Eldorado Mining and Refining Limited and used the old camp and mill to recover silver and copper values from what became known as the Echo Bay Mine.  Production in the Echo Bay workings ceased in 1975.  The company then reopened the old Eldorado Mine workings and produced more silver and copper until 1981 when low silver prices closed the mine for good. The McIntyre Community Building was constructed in Timmins, Ontario, Canada in 1938 by McIntyre Mines owner J. P. Bickell.  At the time, it was one of the finest recreational centres in Canada outside of a major centre. The McIntyre mine is an abandoned underground gold mine in Schumacher, Ontario, Canada, which has earned a place in Canadian mining history as one of the nation's most important mines.  Its iconic headframe, located near downtown Timmins, has come to represent the entire Porcupine Gold Rush.  The McIntyre also yielded a considerable amount of copper over its life. The Cross-border Mining Education Trail (German: "Grenzüberschreitender Bergbaulehrpfad" , ) from Krupka (German: Graupen) to Geising, Altenberg, Zinnwald and Cínovec (German:Böhmisch Zinnwald) to Dubí (German: Eichwald) is a 40 km long mining history educational trail in the upper Eastern Ore Mountains in Germany and the Czech Republic.  It links seventy sites (including museums, monuments, visitor mines, mining ponds and ditches, reclamations and tourist attractions) connected with the history of mining and settlement in this cross-border region of the Ore Mountains.  The educational trail describes the development of what was once the most important tin mining regions in Central Europe.  In order to hike the trail, a walking map is recommended that contains detailed maps and short descriptions of the waypoints en route and the opening times of the museums. TVI Pacific Inc. (TVI) is a Canadian mining company headquartered in Calgary.  TVI's Canatuan mines were the first foreign-invested mine in the Philippines after the passage of the Philippine Mining Act of 1995.  From 2004 to 2014, TVI produced 105,200 oz of gold, 1.8 e6oz of silver, 199,778 t of copper and 30,558 t of zinc concentrate Revenues over the 10-year period totalled US$478 million.
Answer: The McIntyre mine
