  • SERIES Tions Are Reflected on the Physiographic Map of the Area
    GEOSCIENCE CANADA Volume 46 2019 137 SERIES tions are reflected on the physiographic map of the area. Despite abundant glacial deposits, we now know that the camp comprises several groups of Ordovician predominantly vol- canic rocks, belonging to the Dunnage Zone, which overlie older sedimentary rocks belonging to the Gander Zone. The volcanic rocks formed during rifting of a submarine volcanic arc on the continental margin of Ganderia, ultimately leading to the formation of a Sea of Japan-style basin that is referred to as the Tetagouche-Exploits back-arc basin. The massive sul- phide deposits are mostly associated with early-stage, felsic volcanic rocks and formed during the Middle Ordovician upon or near the sea floor by precipitation from metalliferous fluids escaping from submarine hot springs. The history of mineral exploration in the Bathurst Mining Camp can be divided into six periods: a) pre-1952, b) 1952- 1958, c) 1959-1973, d) 1974-1988, and e) 1989-2000, over which time 45 massive sulphide deposits were discovered. Prior to 1952, only one deposit was known, but the efforts of three men, Patrick (Paddy) W. Meahan, Dr. William J. Wright, and Dr. Graham S. MacKenzie, focused attention on the min- eral potential of northern New Brunswick, which led to the Steven R. McCutcheon1 and James A. Walker2 discovery of the Brunswick No. 6 deposit in October 1952. In the 1950s, 29 deposits were discovered, largely resulting from 1McCutcheon Geo-Consulting, the application of airborne surveys, followed by ground geo- 1935 Palmer Drive, Bathurst, New Brunswick, E2A 4X7, Canada physical methods.

Bathurst Mining Camp Global comparison of massive sulfides GEODE Team: Steve McCutcheon (New Brunswick Geological Survey) David Lentz (University of New Brunswick) Garry Woods (Noranda Exploration) Jim Walker (New Brunswick Geological Survey) 5.1 Age and tectonic/structural setting 5.1.1 What is the age of your VMS district? Early to Middle Ordovician (480-457 Ma). • Extent, type and precision of geochronology? (belt scale and deposit scale). At belt scale there are about twenty high precision U-Pb radiometric ages (see Figure 1 attached); at deposit scale there are two. • Palaeontological control. Three graptolite localities from slates that cap the volcanic pile; one brachiopod and two conodont localities from within the pile. 5.1.2 What is the current interpretation of the tectonic setting of your VMS district? (include a time-sequence diagram if available). An ensialic back-arc basin that was incorporated in a subduction complex. See Figure 2 attached for cartoon model. 5.1.3 What is the tectonic interpretation based upon: • structural mapping and interpretation? (quality of mapping?). Good quality 1:20,000 scale mapping, lithogeochemistry and a preserved blueschist. • gravity and/or magnetic data (has it been used?). Regional gravity data are sparse. High resolution airborne magnetic and electromagnetic data exist for the entire camp, which to date have mainly been used as an aide to mapping; limited modelling of the digital data.

  • SERIES Had a Gossan Cap, from Which Gold Was Extracted
    GEOSCIENCE CANADA Volume 47 2020 143 SERIES had a gossan cap, from which gold was extracted. In 2012, the value of production from the Bathurst Mining Camp exceeded $670 million and accounted for 58 percent of total mineral production in New Brunswick. Base-metal production started in the BMC in 1957 from deposits at Heath Steele Mines, followed by Wedge in 1962, Brunswick No. 12 in 1964, Brunswick No. 6 in 1965, Caribou in 1970, Murray Brook, Stratmat Boundary and Stratmat N-5 in 1989, Captain North Extension in 1990, and lastly, Half Mile Lake in 2012. The only mine in continuous production for most of this time was Brunswick No. 12. During its 49- year lifetime (1964–2013), it produced 136,643,367 tonnes of ore grading 3.44% Pb, 8.74% Zn, 0.37% Cu, and 102.2 g/t Ag, making it one of the largest underground base-metal mines in the world.

The economic value of metals recov- Part 2: Mining History and Contributions to ered from Brunswick No. 12 alone, in today’s prices exceeds Society $46 billion. Adding to this figure is production from the other mines in the BMC, along with money injected into the local Steven R. McCutcheon1 and James A. Walker2 economy from annual exploration expenditures (100s of $1000s per year) over 60 years.

Le camp est né en octobre Aller au sommaire du numéro 1952 avec la découverte du gisement Brunswick n° 6 et a suscité une ruée au jalonnement sans précédent avec le plus d’hectares revendiqués dans la province qu’à présent. En 1952, on savait peu de choses sur la géologie du camp minier de Bathurst ou sur les conditions de déposition de ses gisements minéraux, car l’accès Éditeur(s) était très limité et la zone était en grande partie recouverte de forêt. Nous avons beaucoup appris depuis cette période. Le camp était recouvert de glace au cours de The Geological Association of Canada la dernière période glaciaire et diverses directions d’écoulements glaciaires sont révélées sur la carte physiographique de la région. Malgré des dépôts glaciaires ISSN abondants, nous savons maintenant que le camp comprend plusieurs groupes de roches ordoviciennes à prédominance volcanique, appartenant à la zone Dunnage, 0315-0941 (imprimé) qui recouvrent de plus vieilles roches sédimentaires de la zone Gander.
