@nsgov announced new rebates for electric vehicles yesterday. Mining makes #greentech like electric cars possible because they are mostly made of minerals and metals.

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...

We love getting questions about mining, minerals and geology! We were asked if we know what these intriguing circles are in #Walton, #HantsCounty.

#nspoli #cbpoli #novascotia @MLAChuckPorter @EastHantsNS #easthants ImageImage
The person who asked isn’t the only one who has noticed the circles. With satellite images so easy to access on the Internet, others have also noticed them, including the excellent staff @NS_Energy_Mines.
#nspoli #cbpoli @MLAChuckPorter @EastHantsNS Image
They investigated them in the early 2000s, thinking they could be sand/mud volcanoes.
A sand volcano is a cone-shaped landform created by liquefied sand being expelled from underground onto the surface.

We love getting questions about mining, minerals and geology! We were asked about the historical #Londonderry #iron mines. Here's the story...

#nspoli #novascotia #cbpoli @ZannLenore @MunColchester #colchester #nshistory ImageImageImage
Iron mining and smelting began in #NovaScotia in 1825 when iron mines opened at Nictaux Falls, #AnnapolisCounty, and the Annapolis Iron Mining Company built a blast furnace at Clementsport between #AnnapolisRoyal and #Digby.
#nspoli #cbpoli #colchester Image
Iron has also been mined in numerous other locations in #NovaScotia, including East River, Bridgeville and Stellarton (#PictouCounty), Brookfield and Economy Mountain (#ColchesterCounty), Erinville and other places in #GuysboroughCounty...

We love getting questions about mining, minerals and geology! We were asked about mining in Victoria Mines, #CapeBreton.
We are going to discuss #VictoriaMines + #NewVictoria since their mining histories are closely linked.
#nspoli #cbpoli #novascotia @KCoombesMLA @JaimeBattiste ImageImage
The first land grants in #VictoriaMines were given to Irish settlers in 1794 and in New Victoria in 1808.
#Coal mining in the area began in 1865 with what we now call the Old Victoria Mine, which was likely the 1st mine in North America planned to be completely...

...under the sea floor. It was based on the shore just north of the intersection of the New Waterford Highway (#28) and Lake Road (circled in red on the map below). The #coal from this mine was conveyed by a railway 5.5 kms long to the Victoria Pier at South Bar for shipment. Image

Lots of places in #NovaScotia were named for their connections to mining – but #GoldRiver is NOT one of them!
#Gold was discovered in Gold River, #LunenburgCounty, in September 1861 by Daniel Dimmock of nearby #Chester.
#nspoli #cbpoli @Pier12Hugh @BernJordanMP ImageImageImage
However, #GoldRiver is believed to have been named after a Mr. Gould, an early settler, and it’s original name was Gould River. The name was changed to Gold River before #gold was discovered there.
#nspoli #cbpoli @Pier12Hugh @BernJordanMP #NovaScotia Image
The area produced 7610 ounces of #gold between 1881-1940 and today it is beautiful natural space and a bunch of homes on Lacey Mines Road.

Mining built #NovaScotia!
The old #BankofMontreal building in Sydney was built 1900-01 of sandstone from Wallace, the area that provided stone for so many historic buildings like our legislature and parts of Ottawa's parliament buildings.
#nspoli #cbpoli @HomeMattersCB @OldSydney ImageImage
The bank was built because of the economic boom that occurred in #Sydney in that era. Large steel plants located in Sydney, fed by nearby #coal mines, made Sydney a hub of commercial and industrial activity.
#nspoli #cbpoli @HomeMattersCB @OldSydney Image
The building was designed by renowned architect Sir Andrew Taylor of Taylor and Gordon. Its Palladian windows, copper dome, columns, and pediments combine to make a striking building. It’s one of the best examples of commercial Neo-classic architecture in NS.

The Point Aconi coal mine, before and after!
A surface mine operated at #PointAconi, #CapeBreton, from 2006-2013 and today the site is greenspace with ponds and ocean views.
#nspoli #cbpoli #novascotia @JaimeBattiste @CBRMGov ImageImageImageImage
It’s a great example of reclamation mining – cleaning up historical mines by completing extraction and returning them to nature or preparing them for other uses.
#nspoli #cbpoli #novascotia @JaimeBattiste @CBRMGov Image
The mine was on the site of the old Prince Mine, which opened in 1975 and closed in 2001. It produced about 1 million tons of coal per year and sold it to #NovaScotia Power to generate electricity at the #PointAconi power plant, immediately next to the mine.

Today’s mining/quarrying industry is a sophisticated, science-based business that provides essential materials we all use every day – and a very different industry than in the past.
#nspoli #cbpoli #novascotia #capebreton @TimHoustonNS @ChenderMLA @HomeMattersCB @AllanMacMaster Image
Mining/quarrying is #NovaScotia’s highest-paying resource industry. Its average total compensation (wages+benefits) is $87,000 per year. An entry-level job like haul truck driver pays an average $25/hour.
#nspoli #cbpoli @TimHoustonNS @ChenderMLA @HomeMattersCB @AllanMacMaster Image
97% of jobs at #NovaScotia mines and quarries are filled by Nova Scotians. The industry is committed to hiring locally.

We love getting questions about mining, minerals and geology! We were asked about Nova Scotia’s version of the San Andreas Fault - the Cobequid-Chedabucto Fault System!
Nova Scotia has two halves geologically...
#nspoli #cbpoli #NovaScotia #CapeBreton ImageImage
#NovaScotia has 2 halves geologically: The northern half came from Europe and the southern half from Africa. The Cobequid-Chedabucto Fault System is where they collided 400 million years ago. This caused earthquakes, melted rocks+concentration of minerals like #gold+zinc.
#nspoli Image
People sometimes think of it as a single fault that cuts the province in half. In fact, it's a fault zone or system, not a single fault. There are several large parallel, or nearly parallel, faults that collectively make up the system.

#SydneyMines played a key role in #NovaScotia’s coal mining and industrial history.
Here's the story...
#nspoli #cbpoli #CapeBreton #nshistory @HomeMattersCB @JaimeBattiste @CBRMGov @AllanMacMaster @KCoombesMLA #coal ImageImageImage
#SydneyMines was named after Thomas Townshend (1733-1800), First Viscount Sydney, who was British Home Secretary in the Pitt Government in the 1780s. He was an important player in negotiating the Canada-US border.
#nspoli #cbpoli #CapeBreton #novascotia #nshistory Image
He felt the British needed to keep Canada so loyalists – Americans who supported the British side in the US War of Independence - would have a safe haven to go to after the war.

We love getting questions about mining, minerals and geology! We were asked about the historical #gypsum quarry which today is the beautiful Kempt Quarry Recreation Site in #WestHants.
Here's the story:
#nspoli #cbpoli #novascotia @MLAChuckPorter @RegMunWWH #nshistory ImageImage
Gypsum quarrying began in #HantsCounty in the 1700s when farmers exported it as fertilizer. #Gypsum fixes alkaline (high pH) soil. US inventor Ben Franklin learned this from the French and brought the idea to the US in 1785.
#nspoli #cbpoli #novascotia @MLAChuckPorter @RegMunWWH Image
There have been many #gypsum quarries in #Hants over the years, including several in the #KemptShore/Cheverie area.
There were two quarries near #Cheverie that operated in the 1900s, the Cove and Upper Head quarries. The Cove Quarry was close to the shipping pier.

One of #NovaScotia's oldest mines was the Sibley Mountain Slate Quarry in #ColchesterCounty. From the 1770s to 1860s it provided shingles and flagstones for buildings in #Halifax and England.
Here's the story...
#nspoli #nshistory @LarryHarrisonPC @ZannLenore @MunColchester ImageImage
Only the early Acadian mines at Joggins, which provided coal for Fort Beausejour and Port Royal, and the French mine at Port Morien, which provided coal for Louisbourg, are known to be older.
#nspoli #nshistory @LarryHarrisonPC @ZannLenore Image
The Sibley Mountain quarry was built on land owned by John Olemixon and was commissioned by his close friend, John Wentworth, who became Lieutenant Government of #NovaScotia in 1792.

Why is amethyst purple?
Most #amethyst forms when lava with gas bubbles in it hardens and creates rock with cavities (i.e. the lave crusts over before gasses in the lava can escape, leaving a hollow area inside the rock).
#nspoli #cbpoli #novascotia Image
The cavities fill with silica-rich liquid that contains trace amounts of iron. Over time, this liquid forms crystals that line the cavity walls. After crystallization, gamma rays, emitted by radioactive materials in the host rock, irradiate the iron to produce the purple color. Image
The word #amethyst comes from the ancient Greeks who thought it looked like wine and figured the gem prevented its wearer from getting drunk. “Amethystos” is Greek for "not intoxicated."

The East Gore Slate Quarry in #EastHants likely started operating in the mid-1800s and operated into the early 1900s.
Here's the story of the quarry and how it's connected to Courthouse Hill and the Rawdon #gold mines!
#nspoli #novascotia @EastHantsNS #hants ImageImage
The historical quarry is on turn-of-the-century geological maps but there are no official records of its production, so precise dates aren’t available.
A mill was built nearby to turns its slate into roof shingles.
#nspoli #novascotia #easthants #hants Image
Today there is a modern slate quarry directly across Slate Quarry Road from the historical quarry.
One of the many old buildings that used East Gore slate for its roof was the courthouse on what we now call Courthouse Hill, but which was once known as Judgement Hill.

McKeens Quarry in #Pictou County is one of the oldest quarries in #NovaScotia. It began producing sandstone in the mid-1800s under the name Fogo Quarry and was worked continuously until the 1940s.
#nspoli @TimHoustonNS @karla_macf_pc @SeanFraserMP @TOWNofPICTOU @PictouCounty_NS ImageImageImage
It was later quarried to produce rock fill and armour stone.
McKeens stone was used in many heritage buildings, including the Charlottetown legislature and @NewGlasgowNS Town Hall which was built 1884-1887…at a cost of $43,285.61!
#nspoli @TimHoustonNS @karla_macf_pc ImageImage
It was commissioned by Prime Minister Sir John A. MacDonald, one of 78 Post Offices/Custom Houses he built across Canada. It was also briefly the town's courthouse. The Town of #NewGlasgow bought the building after the old Town Hall was severely damaged by fire in 1957.

Happy Vulcanalia!
Yesterday was the ancient festival to celebrate Vulcan, the Roman god of fire who was renowned for his metalworking skills.
#nspoli #cbpoli #capebreton #novascotia ImageImage
As a son of Jupiter, Vulcan was the creator of his father's lightning bolts. He also made armor, weapons and jewelry for the gods and heroes of Rome.
#nspoli #cbpoli #capebreton #novascotia Image
Volcanoes are named after him. It’s said that every time his wife, Venus, was unfaithful – which was apparently quite a lot – he got angry and hammered red-hot metal at his forge with such ferocity that it created volcanic eruptions.
