Gold was discovered in Renfrew, originally known as Nine Mile River, in 1861 by William Thompson who found a boulder that contained #gold on the banks of the brook near his saw mill. Later that year, John McPhee discovered additional quartz veins near Thompson's mill.
#nspoli #NS ImageImage
These discoveries led to a swirl of activity by many small companies and prospectors staking claims.
Production began in 1862 but didn't boom until 1863 when #gold recovery more than doubled from 308 ounces in 1862 to 785 ounces in 1863.
#nspoli #novascotia #nshistory #mining Image
In 1864 mining increased significantly but no crushing of ore was done during the last three months of the year due to a drought, water being essential to the process.
#nspoli #novascotia #nshistory #mining #gold Image
1864 was still a good year though - production increased to 874 ounces, but it would have been higher had there been more rain.
During the next few years many companies were attracted to the area and numerous shafts and test pits were sunk.
#nspoli #novascotia #nshistory #mining Image
1867 was the banner year for the district - production of 9401 ounces made Renfrew the leading #gold district in the province that year.
#nspoli #novascotia #nshistory #mining Image
After that production began to lag, hitting a low of only three ounces of #gold in 1874. Mining in the Renfrew area continued but was small-scale for many years.
#nspoli #novascotia #nshistory #mining Image
In 1900, following the finding of some very rich ore, 4,450 ounces were recovered and 3584 ounces were produced in 1901. But after that, interest in the area was intermittent in the following decades, with modest production.
#nspoli #novascotia #nshistory #mining #gold Image
Some exploration took place in 1983-84 and 109 grams of gold were produced in 1992. Some additional small-scale mining in 1993 produced gold mostly for local #Halifax-area jewelers.
#nspoli #novascotia #nshistory #mining #gold Image
In total, Renfrew produced 51,985.9 ounces of gold, 49,000 ounces of it in the historical period from 1862-1927.
#nspoli #novascotia #nshistory #mining #gold Image
The Renfrew #Gold District has the distinction of having what was probably one of the richest leads known to the province during the years 1862-1913. The Preeper Lead produced 180 ounces of gold from 83 tons of quartz, an average of over two ounces of gold per ton of ore.
#nspoli Image
To put that in perspective, output at successful modern gold mines is measured in grams per ton, not ounces, so two ounces per ton is spectacular by today’s standards.
#nspoli #novascotia #nshistory #mining #gold Image
During Renfrew’s gold rush in the 1800s, it had 700 resident miners, a post office, a school, two bars, two hotels, a bakery, numerous stores, blacksmith shops, stables for 50 horses, and two miles of wooden boardwalk.
#nspoli #novascotia #nshistory #mining #gold Image
When mining started in 1862, a Renfrew miner earned, on average, $176 for the year. By 1866 he took home $1,050.90 or $3.21 for every working day - at a time when a daily wage for unskilled labour was less than one dollar.
#nspoli #novascotia #nshistory #mining #gold Image
The average wage at the #MooseRiver mine, currently Nova Scotia’s only producing gold mine, is $85,000 per year so gold mining continues to be a highly-paid job.
#nspoli #novascotia #nshistory #mining #gold Image
Famous #NovaScotian prospector Edmund Horne began his career in Renfrew and nearby Oldham.
#nspoli #novascotia #nshistory #mining #gold Image
After years of struggle, in 1920 he scrounged together a group of investors and, with a whopping $225 in backing that took him 2 years to raise, he and a fellow prospector staked a claim of 70 acres at Osisko Lake in Quebec that became Canada’s largest copper-gold-silver deposit. Image
Horne also founded mining company, #Noranda, which eventually had 32,000 employees.
With his fortune made, Horne lived out his days in Nova Scotia on a 1,000-acre estate, Monte Vista, along the shores of Grand Lake at Enfield.
#nspoli #novascotia #nshistory #mining #gold Image
He raised cattle, drove fancy cars, smoked cigars and sported his well-recognized raccoon coat. But he never got over his gold fever - he spent an estimated $500,000 unsuccessfully searching for gold in Renfrew before he passed away in 1953.

@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...
