| Mine | Coordinates | Town | Owner | Dates | Comments |
| Springhill coalfield | 45°40′N 64°4′W | Springhill, Nova Scotia | A.V. Roe Canada Company Ltd. | ????-1958 | Coal was so prevalent in the town that "there was a time when men got coal out of their backyards; shallow pits were found everywhere. In recent years, there have been instances when a homeowner would step out of his door only to find a big gaping hole where his driveway had been. Another part of an old mine had caved in." [1] |
| Westray Mine | 45°33′14″N 062°38′44″W | Plymouth, Pictou County, Nova Scotia | Curragh Resources | 1991-1992 | It was the site of an underground methane explosion on May 9, 1992. The explosion resulted in the deaths of all 26 miners who were working underground at the time. [2] |

| Catcha Lake | 44°44′09″N63°11′40″W / 44.73583°N 63.19444°W | Halifax Regional Municipality | Acadian Gold Corporation | 1882–Present | The report indicated that 20,734 tons of ore had been crushed to date, resulting in the recovery of 22,757 ounces of gold valued at that time at $19.00 per ton WJW. Today the Acadian Gold Corporation controls approximately 6.4 kilometres of strike length on this structure and is planning to drill for samples in the future . |
| Moose River Gold Mine | 44°59′03″N 62°56′34″W | Moose River | Acadian Gold Corporation | 2017–present | The Moose River operation currently provides full-time employment to over 300 Nova Scotians, plus indirect and contractor positions. In its first year alone, the mine produced over 90,000 ounces of gold. [5] As of March 25, 2019, the Moose River operation had a combined estimate of 1.9 million ounces of gold in reserve at a grade of 1.12 grams per tonne. [6] |
The Nova Scotia Department of Natural Resources created the Abandoned Mine Openings Database, which is an inventory of abandoned mine workings from both underground operations and advanced exploration in the province. In the database, over 600 mining areas have been identified, consisting of over 7,000 shafts, adits, slopes, trenches, and associated underground workings which are or once were open to the surface. The database is updated regularly whenever locations are visited, or new mine openings are identified. The inventory can be filtered by mine opening name, mine opening type, location, claim, reference map, landowner type, commodity mined, county, name of vein or seam, hazard degree and by mine opening original depth. [7]
The Nova Scotia Department of Natural Resources created the Abandoned Mine Openings Remediation Program in 2001 which has a budget of $50,000 a year to remediate openings that are located mainly on crown land, of which there are 2000. The Geoscience and Mines Branch of the Department of Natural Resources carries out regular inspections of the openings. This is managed on a three-year cycle in which almost every abandoned mine opening on crown land is inspected and assigned a degree of hazard. The hazard ratings range from Type I (inescapable) to Type IV (no significant hazard) and the openings are remediated in order of safety hazard. Closing all of the Type I abandoned mine openings on Crown land was the top priority of the Abandoned Mine Openings Remediation Program and was accomplished by the end of 2011. Remediation is completed by means of back-filling, fencing or placement of concrete caps over the mine opening. [8] As deforestation and urban development increase, abandoned mines have become an important source of habitat for a number of bat species. Thus, the closure of abandoned mine openings presents a potential threat to bat populations. In response, habitat surveys have become an essential part of abandoned mine assessments. Should the area be deemed important for habitat preservation, the method of closure will be designed to suit the resident species. [9]
From 2001 to 2015, approximately $810,000 was spent remediating hazardous openings on crown land. As of 2015, all 40 Type I abandoned mine openings and approximately 40% of Type II openings on crown land have now been remediated. [10]
In 2019, the Auditor General of Nova Scotia identified a significant control weakness relating to the Department of Lands and Forestry’s financial reporting of abandoned mine sites. The Department of Lands and Forestry had not completed adequate investigations at all abandoned mine sites which were identified to have possible areas of contamination. Unidentified potential contaminants may result in ecological or human health concerns. Further investigation is ongoing. [11]

Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process has resulted in its damage. Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry.
The Westray Mine was a Canadian coal mine in Plymouth, Nova Scotia. Westray was owned and operated by Curragh Resources Incorporated, which obtained both provincial and federal government money to open the mine, and supply the local electric power utility with coal.

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
The Devco Railway was a Canadian railway. Devco Railway operated as an unincorporated department within the Coal Division of the Cape Breton Development Corporation, also known as DEVCO; as such there is no formally incorporated entity named "Devco Railway".

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.
The Cumberland Railway and Coal Company is a defunct Canadian industrial company with interests in coal mines in Springhill, Nova Scotia, and a railway that operated from Springhill Junction to Parrsboro.
Point Aconi is a rural community in Nova Scotia at the northeastern tip of Boularderie Island. It derives its name from the headland of the same name, Point Aconi.
An abandoned mine refers to a former mining or quarrying operation that is no longer in use and has no responsible entity to finance the cost of remediation and/or restoration of the mine feature or site. Such mines are typically left unattended and may pose safety hazards or cause environmental damage without proper maintenance. The term incorporates all types of old mines, including underground shaft mines and drift mines, and surface mines, including quarries and placer mining. Typically, the cost of addressing the mine's hazards is borne by the public/taxpayers/the government.
The Springhill Institution is a Canadian federal corrections facility located in the town of Springhill, Nova Scotia.
The Halifax Convention Centre is the main conference centre in Halifax, Nova Scotia, Canada. It opened on December 15, 2017 in Downtown Halifax, replacing the older World Trade and Convention Centre.
The environmental impact of Iron ore mining in all its phases from excavation to beneficiation to transportation may have detrimental effects on air quality, water quality, and biological species. This is as a result of the release of the large scale of iron ore tailings into the environment which are harmful to both animals and humans.
Springhill Coal Mining is a National Historic Site of Canada located on the corner of Industrial Park Drive and Memorial Crescent in Springhill, Nova Scotia. The Historic Site, designated in 1998, consists of a museum and the land that once contained the Springhill Coal Mines. Springhill was once one of the most important coalfields in Canada, along with those in Pictou and Cape Breton. Springhill coal was shipped and marketed throughout the Maritimes and Quebec. The surviving mining features in Springhill are among the most complete in Canada. The Springhill Mines were made infamous by a number of disasters that occurred underground, including the 1891 explosion, the 1956 explosion and the 1958 bump.
