Gold was discovered at #LakeCatcha, #Halifax County, in 1865 but not much attention was payed to the discovery until 1881.
Check out this thread for the history of the Lake Catcha #gold district!

Most of the mining and development in this district was done by the Oxford #Gold Mining Company which was very active from 1881-1896. By 1882 Oxford had acquired a number of areas north of the lake, erected a 10-stamp mill and become a steady producer.
#nspoli #cbpoli #novascotia Image
Under J. M. Reid, the company’s mine manager, Lake Catcha became one of the most productive #gold districts in Nova Scotia.
Unfortunately, Reid had to quit work in late 1894 due to health issues after running the Oxford mine for 10 years.
#nspoli #cbpoli #novascotia Image
He passed away months later, in July 1895, and the company’s production plummeted from 1643 ounces in 1894, when Reid was running the mine, to 396 ounces in 1895 and 90 ounces in 1896.

While Oxford was the biggest producer in the area, a number of other companies also did smaller-scale mining and prospecting at Lake Catcha.
#nspoli #cbpoli #novascotia #capebreton #nshistory #gold Image
However, their production was measured in hundreds of ounces of #gold per year (or less), not thousands, as had been the case many of the years that Oxford was in operation.
#nspoli #cbpoli #novascotia #capebreton #nshistory Image
After 1915, little work was carried out at Lake Catcha until the mid-1930s when there was again some small-scale mining. Between 1940-41 there was production of 245 ounces of #gold, the last produced at #LakeCatcha.
#nspoli #cbpoli #novascotia #capebreton #nshistory Image
There has been sporadic exploration at #LakeCatcha since the 1970s and there is likely still significant potential in the area. Over 100 quartz veins were found in the district but historical mining was limited to only about six veins.
#nspoli #cbpoli #novascotia #nshistory #gold Image
Modern science also makes it possible to target disseminated #gold – tiny flecks of gold scattered throughout host rock – as is being done today at the hugely successful #MooseRiver mine.
#nspoli #cbpoli #novascotia #capebreton #nshistory Image
In total, 25,947 ounces of gold were produced in the #LakeCatcha District, most of it by the Oxford #Gold Mining Company which produced 17,166 ounces between 1882-1896.

@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...
