FACTS ABOUT GOLD AND THE ENVIRONMENT
#Gold #mining is bringing 100s of millions of $ in investment to #NovaScotia and creating 100s of jobs for #NovaScotians.
Modern mining is a sophisticated science-based activity that takes proper care of the enviro.

@Guysboro #Reclamation - Before getting operating permits, #NovaScotia #mining companies must get government approval of reclamation plans and post reclamation bonds that ensure funds are available to properly take care of sites.

@Guysboro Water Management: Mine operators are required to treat, strictly monitor and test water, and report to @nsgov. Water is usually recycled on-site. Water released back into a river or lake is usually cleaner after it has been used in a mine or quarry than it was beforehand.

@Guysboro @nsgov Uranium and arsenic occur in all #NovaScotia rock. They are unstable and often leach naturally into groundwater. It's important to test wells for them. #Mining does not release #uranium and #arsenic or create a problem that did not already exist.
#nspoli #NS #minerals #geology Image
@Guysboro @nsgov Mercury: Modern #gold #mines do not use #mercury. It’s an obsolete method of processing that is harmful to the #environment. Mercury has not been used in #NovaScotia since the early 1900s.
#nspoli #mining #minerals #geology Image
@Guysboro @nsgov Historical Mines - We agree historical #gold mines were not properly managed, just like most human activities 100-150 years ago. Mines like #Montague and #Goldenville started in the 1860s. However, historical sites like these have nothing to do with modern #mining.
#nspoli #NS Image
@Guysboro @nsgov Modern mines can sometimes fix issues with historical sites by cleaning up tailings or stabilizing land that was left unusable by the pick and shovel mining of the distant past. For example, the #Touquoy gold mine has cleaned up historical tailings in #MooseRiver.
#nspoli #NS Image
@Guysboro @nsgov Most industries have legacy issues. Governments paid to clean up sites like the #Sydney tar ponds, #Amherst Aerospace and #Trenton's Tibbetts Paints. #Mining also has legacy issues but they date from another era and the industry takes proper care of the environment today.
#nspoli Image
@Guysboro @nsgov #Mining employs 5,500 #NovaScotians, mainly in rural areas. We are #NovaScotia's highest-paying #resource industry with average wages of over $55,000 per year. An entry-level job, such as haul truck driver, pays an average of $25 per hour.

@nsgov announced new rebates for electric vehicles yesterday. Mining makes #greentech like electric cars possible because they are mostly made of minerals and metals.
#nspoli @KeithIrvingNS @IainTRankin @NS_Energy_Mines @ns_environment @ChenderMLA @AllanMacMaster @MLAChuckPorter Image
For example, an e-car has 183 pounds of copper wiring in it because copper is used in every major component from the motor to the inverter and the electrical wiring. There is about four times more copper in an e-car than in a car with an internal combustion engine.
There are about 400 electric cars on Nova Scotia roads - a total of over 73,000 pounds of copper!
An electric car uses 25-50 grams of silver, so Nova Scotia’s 400 e-cars contain about 15,000 grams of it.

The Morris Street Engine House has been declared a municipal heritage property!
#Halifax’s Fire Station #2, as it is also called, was built 1907-08 of reinforced concrete.
Here's the story!
#nspoli @HFXFireHistory @HRMFireNews @hfxfire @HFXFirefighters @hfxgov @MikeSavageHFX
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. (The terms cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete...
#nspoli
...Cement is the glue that holds concrete together.)
Reinforced concrete means the concrete is poured over a frame, usually steel bars, that give the structure greater strength.

We love getting questions about mining, minerals and geology! We were asked about sinkholes and whether they are a risk when walking in the woods.
#nspoli #cbpoli #novascotia #capebreton @oxfordsinkhole ImageImage
The short answer is yes, sinkholes are real but no, they are not a major risk and should not prevent you from enjoying outdoor activities.
Most natural sinkholes are caused by groundwater naturally eroding rocks like gypsum, salt and limestone which are water-soluble.
#nspoli Image
The water erodes the rock, leaving an underground cavern. Eventually, the weight of the rock and earth above the cavern causes the sinkhole to form. Sinkholes can form either gradually (i.e. a small depression appears and perhaps grows larger over time) or by sudden collapse. Image

We love getting questions about mining, minerals and geology! We were asked about the historic #NewCampbellton coal mine in #VictoriaCounty.
#nspoli #cbpoli #novascotia #capebreton #nshistory
@JaimeBattiste ImageImage
The New Campbellton coal mine was opened in 1862 by Charles J. Campbell, a former Member of Parliament, Member of the Legislative Assembly and executive council member. The community had been named Kelly’s Cove but was changed to New Campbellton in 1862 in honour of Mr. Campbell. Image
A sample of New Campbellton’s coal was sent to the 1865 Dublin Exhibition and “was very favorably noticed by the Judges,” according to a report.

Mining built #NovaScotia!
#Halifax was founded in 1749 and its first court house is reported to have been built by 1754 on the northeastern corner of Buckingham + Argyle streets. After the building burned in 1789, the courts were temporarily housed in various buildings.
#nspoli ImageImage
In April 1851 a bill to provide Halifax with a county court house was passed. Mr. H.G. Hill, a prominent #Halifax architect, prepared a plan for a wooden building.
However, since the records of the county, wills, deeds and other papers of public office were...
#nspoli #novascotia Image
...to be stored in the court house, it was important that the building be fire-proof. Also, a number of serious fires in #Halifax in 1857 led to the passage of a bylaw that required large buildings be made of stone or brick, so Hill's plans for a wooden building were abandoned. Image

The Sullivan Creek #coal mine, before and after!
It's one of several mines reclaimed around #AlderPoint #CapeBreton in the late 1900s/early 2000s - examples of how mining makes temporary use of land and then land can be used other ways.
#nspoli #cbpoli #novascotia @JaimeBattiste ImageImage
The first mine in the area was the Scotia Mine, or #NovaScotia Steel & Coal Company No. 4 Colliery, on Toronto Road, which operated on the Sydney Main (Harbour) Seam from 1915 to 1921.
#nspoli #cbpoli #novascotia @JaimeBattiste ImageImage
Coal quality and structural issues (including water inflow) plague the Harbour Seam west of Florence so upon closure of the colliery, production on the Harbour Seam was limited to the Company’s No. 3 Colliery in Florence, which had opened in 1902...
