According to the Government of Canada report, Mount Pleasant is "North America's largest tin deposit and the world's largest reserve of indium."Wright, Phillip. "Mineral and Metal Commodity Review: Tin." Natural Resources Canada, 1996. The company's stock trades on the [TSX Venture Exchange](/source/TSX_Venture_Exchange) under the symbol ADE. Adex holds 102 mineral claims at Mount Pleasant covering approximately 1,600 hectares (4,000 acres), as well as 405 hectares (1,000 acres) of surface rights.[http://www.adexmining.com/corporate.php Adex Mining Inc. - Company Profile {{pipe}} Natural Resources & Emerging Mining Company] {{webarchive |url=https://web.archive.org/web/20110707083739/http://www.adexmining.com/corporate.php |date=July 7, 2011 }} Mount Pleasant's Fire Tower Zone contains [tungsten](/source/tungsten)-[molybdenum](/source/molybdenum) mineralization, and is the site of a past-producing tungsten mine operated by [Billiton](/source/BHP) from 1983 to 1985.Truscott, Brian. "Adex in Redux Mode." Dow Jones Newswires, reprinted in the National Post, November 21, 2007. The property's North Zone is the focus of [tin](/source/tin), [indium](/source/indium) and [zinc](/source/zinc) exploration. == Tin-Indium-Zinc at North Zone == Successive historical exploration drilling programs by previous owners of Mount Pleasant began the process of defining the property's tin and indium mineralization centred on the North and Deep Tin zones. Adex acquired Mount Pleasant in 1995 and began conducting exploration and metallurgical tests on the tin-indium areas.Gowan, Derwin. "Mining company clears regulatory hurdle: Adex Mining moves ahead with Mount Pleasant mine. [Telegraph-Journal](/source/Telegraph-Journal) (New Brunswick), December 4th, 2007. In 1997, the property was placed in care and maintenance due to poor economic conditions in the mining industry. The tin-indium-zinc North Zone contains a [National Instrument 43-101](/source/National_Instrument_43-101)-compliant resource estimate of 10,882,000 tonnes in the "indicated" category at 0.43% tin, 67.8 grams per tonne indium, and 0.67% zinc, as well as 7,603,000 tonnes in the "inferred" category at 0.22% tin, 74.6 grams per tonne indium and 0.99% zinc.Dunbar, Paul, et al. "An Updated Technical Review of the Mount Pleasant Property, Including a Mineral Resource Estimate on the North Zone Southwestern New Brunswick for Adex Mining Inc." Watt, Griffis and McOuat Ltd., April 13, 2012. == Tungsten-Molybdenum at Fire Tower Zone == In the early 1980s, [Billiton](/source/BHP) invested approximately $150 million for the construction of a tungsten mine and mill at Mount Pleasant's Fire Tower Zone. The facility was active from 1983 to 1985, milling 990,200 tonnes of tungsten ore at a grade of 0.35%. Challenging economic conditions and a downturn in the price of tungsten led to the mine's closure in 1985. Surface facilities from the mine (including storage areas, conveyor galleries, warehouse space and office space) remain intact on the property. The Fire Tower Zone contains a [National Instrument 43-101](/source/National_Instrument_43-101)-compliant resource of 13,489,000 tonnes in the "indicated" category at 0.33% tungsten and 0.21% molybdenum, as well as 841,700 tonnes in the "inferred" category at 0.26% tungsten and 0.20% molybdenum.{{cite web |url=http://www.adexmining.com/overview.php. |title= Adex Mining Inc.- Property Overview {{pipe}} Tin-Indium Exploration at Mount Pleasant|website=www.adexmining.com |archive-url=https://web.archive.org/web/20101223221641/http://www.adexmining.com/overview.php |archive-date=December 23, 2010}} == Recent activities == In the summer of 2007, Adex reactivated the Mount Pleasant project. Subsequently, the company launched a number of programs designed to move the project towards the definitive [feasibility study](/source/feasibility_study) and mine activation phases. Work to date has focused on both the tin-indium-zinc and tungsten-molybdenum zones on the property and has included exploration drilling, a 43-101 resource estimate on the North Zone and the Fire Tower Zone, upgrading of tailings impoundment structures and other activities.Hill, Liezel. "Canadian junior on the fast track to reopen former Billiton mine." Creamer Media's Mining Weekly, May 22, 2008. == Geology == The Mount Pleasant deposits are located in southern New Brunswick within the [Appalachian Orogen](/source/Appalachian_Orogen). These deposits occur within gently dipping Late Devonian age volcanic and sedimentary rocks that are the remnants of a large epicontinental [caldera](/source/caldera) complex. The regional geology in the mine area is dominated by the [Mount Pleasant Caldera](/source/Mount_Pleasant_Caldera), the exposed part of which measures approximately 13 by 17 kilometres. Multiple layered granitic intrusive rocks and associated mineralization at Mount Pleasant were emplaced along the southwestern margin of the caldera complex. This structure occurs within the northern extension of the Appalachian geosynclinals belt and is situated on the southeast flank of New Brunswick's Central Basin.Dunbar, Paul, et al.
