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.

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 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...
#nspoli #cbpoli Image
...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

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.

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.

Misconceptions about modern #gold mining stem from historical mining practices that we agree were not good enough. No industry took proper care of the environment 100-150 years ago. However, historical sites like these have nothing to do with modern mining.
#nspoli #cbpoli ImageImage
Modern mining is a sophisticated, science-based activity that takes proper care of the environment. Nova Scotia mines are stringently regulated by the provincial and federal governments.
#nspoli #cbpoli #novascotia #capebreton ImageImage
Some people have questions about how we manage the environment, so below is information on some of the questions commonly raised.

The #Walton #barite mine, before and after!
One of the biggest barite deposits in the world is in #HantsCounty. It was mined from 1941-78. Today it's a lovely lake and greenspace.

#nspoli #cbpoli #novascotia #capebreton #nshistory @MLAChuckPorter ImageImageImage
A small, 1 metre-square outcrop of barite was discovered in 1894 but its location was lost to time until 1940 when prospector Roscoe Hiltz rediscovered it. Subsequent exploration confirmed the existence of a major deposit at the site and a surface mine started the following year. Image
In 1955 exploration drilling underneath the barite deposit discovered several metals: lead, zinc, copper and silver. Underground mining started in 1961 and made the site a significant producer of these metals along with its lucrative barite production.

Mining built #NovaScotia!
Sandstone was quarried from a local beach to build Judique’s St. Andrews Church (#InvernessCounty).

#nspoli #cbpoli #capebreton @AllanMacMaster @mikekelloway @BAMacQuarrie ImageImage
Two previous churches, both wooden, burned down due to lightning strikes. Residents decided after the second time, in 1918, that the next church would be made of stone to prevent fires.
#nspoli #cbpoli #capebreton #novascotia @AllanMacMaster @mikekelloway @BAMacQuarrie ImageImage
In 1924, sandstone was extracted from an outcrop on the shore at McKays Point for the building. It was the only stone ever quarried from that site. Residents hauled the stone over frozen ground on sleds to the church.

Environmental science wasn't very sophisticated till the 1990s. That's when #NovaScotia started doing enviro assessments and better-regulating industrial projects. Prior to that, there wasn't much understanding of enviro impacts.
#nspoli @GordonWilsonLNS @TimHoustonNS @ChenderMLA ImageImageImageImage
Mining and its regulation are totally different today. A mine's environmental assessment often takes 3-5 years and costs over a million dollars. It generates dozens of scientific studies.
#nspoli #cbpoli #capebreton @GordonWilsonLNS @TimHoustonNS @ChenderMLA ImageImageImageImage
Governments often ask for even more studies and data. This is proof of how stringently mining is regulated to protect the enviro.
Below are pics of the reclaimed Evans, Coalburn + Drummond mines.

We all love #PeggysCove for how beautiful it is but how it formed also offers a great geology lesson about the three types of rock:
#nspoli #cbpoli #novascotia #capebreton @TourismNS @BernJordanMP @Pier12Hugh @MattWhitman2020 ImageImage
IGNEOUS ROCK: Rocks formed by molten magma are called igneous rocks and can be fine-grained or coarse-grained depending on how closely to the earth’s surface the cooling occurred.
#nspoli #cbpoli #novascotia #capebreton @TourismNS Image
Granite is an example of a coarse-grained igneous rock which cooled relatively slowly beneath the earth’s surface. Granite is often exposed at the surface as overlying rocks are eroded.
SEDIMENTARY ROCK: Sedimentary rocks can be formed by 2 processes.

We love getting questions about mining, minerals and geology!
We were asked about these unusual-looking rocks at Roy Island, just west of #MelmerbyBeach in #Pictou County.

#nspoli #cbpoli #novascotia #capebreton
@TimHoustonNS @karla_macf_pc @SeanFraserMP ImageImage
Coincidentally, Ron van Dommellen, who has a great web site about #NovaScotia minerals (nsminerals.atspace.com), visited the same site recently and reports that the rocks at Roy Island have many plant fossils in them, including sections of branches and trunks.
#nspoli #cbpoli ImageImage
The darker rocks in the centre are a plant fossil that has become a mixture of stone and coal.
The Geological Survey of Canada suggests the yellow material in the picture is likely jarosite, a mineral that contains iron, sulfate and potassium.

Gold was discovered in Voglers Cove, #Lunenburg County, in 1885 when John Mann found gold in a boulder. Augustus Reinhardt also found #gold there the following year.
Four small mines eventually operated along...
#nspoli #cbpoli #novascotia #capebreton
@MarkFurey1 @BernJordanMP ImageImage
...Voglers Brook in the late 1890s to early 1900s in the Voglers Cove #Gold District. Records of their production are incomplete but based on what is known, output was modest.
#nspoli #cbpoli #novascotia #capebreton
@MarkFurey1 @BernJordanMP ImageImage
44 ounces of #gold are known to have been produced from two shafts at the Voglers Cove Mine which had a 5-stamp mill for separating the gold from its host rock. There is an aggregate quarry at the site now.

Mining built #NovaScotia!
Government House – the residence and workplace of Nova Scotia’s Lieutenant Governor – features stone quarried from across #NS.
Here's the story of that beautiful building!

#nspoli #cbpoli #capebreton #Halifax @LtGovNS
@CPMcCreery @HistoricNS @TourismNS ImageImage
When he arrived in #Halifax in 1792, Sir John Wentworth (1737-1820) objected to the dank, less-than-luxurious Governor’s residence. In letters he wrote back to England, he described it as being of “green wood and rotten timbers” and “in danger of falling into the cellar.”
#nspoli Image
So he set about arranging to build a proper country manor for the lieutenant governor’s residence. The site he chose, just off what is now the corner of Spring Garden Road and Barrington St. in #Halifax, had actually been purchased by the government to be...

Gold has many uses, including in all electronics and in medicine (i.e. treating cancer, pacemakers, surgical equipment...).
But how did #NovaScotia's #gold deposits form?
#nspoli #cbpoli #capebreton @ChenderMLA @AllanMacMaster @HomeMattersCB @TimHoustonNS @LarryHarrisonPC ImageImageImage
All #gold on Earth formed billions of years ago in stars that over-heated and blew up. Gold formed in the heat of the explosions and then floated around space. As rock, dust and other materials came together to form Earth, gold was distributed around the planet.
#nspoli #cbpoli Image
400 million years ago North Africa and North America started colliding. Sub-sea sediments were squished between the tectonic plates, upthrusted and folded as they turned into rock.

We love getting questions about mining, minerals and geology! We were asked why volcanoes often form along tectonic plate boundaries:
The Earth’s surface is made up of a dozen large tectonic plates and a number of smaller ones.
#nspoli #cbpoli #novascotia #capebreton Image
These plates move imperceptibly - a few centimetres per year - and over the course of millions of years continents and oceans move and change shape. The plates pulling apart cause fractures or deep rifts in the Earth’s crust, both on land and under the sea...
#nspoli #cbpoli Image
...and plates colliding with each other form mountain ranges and new islands as the rock is forced upwards. It’s this powerful tectonic activity that results in so many volcanoes at plate boundaries.

The #IrishCove limestone quarry, before and after!
This reclaimed #CapeBreton quarry, on the eastern shore of Bras d’Or Lake, started providing metallurgical limestone in the 1960s that was used as flux in SYSCO’s steel mill in Sydney.
#nspoli #cbpoli #novascotia @mikekelloway ImageImage
Flux is used in the smelting process to promote fluidity and remove impurities in the form of slag.
#nspoli #cbpoli #novascotia #capebreton Image
The site was reclaimed in 2003-04. Soil and over 100,000 tons of leftover crushed limestone were used to contour the quarry’s slopes for safety and to re-vegetate it. Today it’s a beautiful greenspace.

We love our coasts - especially in this heat! - but don't often think about how they came to be. Here's how #Halifax's #NorthwestArm formed:

#nspoli #cbpoli #novascotia #CapeBreton
@vote4labi @GaryBurrill @bmaguirens @AndyFillmoreHFX @TourismNS Image
Much of peninsular #Halifax’s bedrock is slate. Sediments deposited as deep-sea muds 500 million years ago were compacted into shale 450 million years ago. When North America and North Africa collided 400 million years ago as a result of tectonic plate movement...
#nspoli #cbpoli Image
...the heat and pressure generated by the collision turned the shale into slate. That’s how slate is formed – it’s metamorphosed (transformed) shale.
The #NorthwestArm was formed by glaciers eroding the slate and carving a trough in the bedrock.

#nspoli #cbpoli #capebreton @NS_Museum @ns_moi @HistoricNS @TourismNS ImageImage
Henry How was responsible for two mineral discoveries in #NovaScotia. How was born in London, England in 1828 and moved to #NS in 1854 to work at King’s College in #Windsor as a professor of natural history and chemistry. He became the university’s vice-president in 1877.
#nspoli Image
How discovered the mineral mordenite, named for Morden (Kings County) where he discovered it in 1864. Mordenite is used to clean up chemical spills, in animal feed and for water treatment.
