Halifax streets may not be paved with gold but some have gold under them!
In the 1800s prospecting on peninsular #Halifax found quartz veins containing small amounts of #gold:
• A 3-inch wide vein near the corner of Oxford Street and Quinpool Road. #nspoli#cbpoli#novascotia
• A 2-inch vein on Louisburg St. between Shirley and Linden. (The name Louisburg St. no longer exists but it’s shown on the 1890 map below near Camp Hill. It may have been an early name for Garden or Vernon but the area has changed so much that it’s hard to be sure.) #nspoli
• A vein between Pepperell and Shirley streets just east of Preston Street. #Gold was also found between Lockman and Upper Water streets, south of North street. (Barrington Street used to be made up of four sections... #nspoli#cbpoli#novascotia
...The portion south of #SpringGardenRoad was called Pleasant Street, the downtown portion was Barrington, the portion north of downtown was Lockman Street and the portion beyond North Street was Campbell Road.) #nspoli#cbpoli#novascotia
In 1897, A 16-inch vein was found while the foundation was being dug for a grandstand at the new Provincial Exhibition Grounds between Almon, Windsor, and Young Streets. #nspoli#cbpoli#novascotia
The exhibition grounds before 1897 were downtown at the corner of Morris Street and Cathedral Lane (formerly Tower Road), where All Saints Cathedral currently stands. The map below shows the original location. #nspoli#cbpoli#novascotia
The 1897 exhibition, at its new home, showcased industries from all over the province, including a 3-stamp #gold mill from the Windsor Foundry Company. #nspoli#cbpoli#novascotia
It was suggested, jokingly, that the vein by the grandstand should be mined so both mining and processing could be demonstrated at the exhibition.
The exhibition drew crowds of over 60,000 that year and a visit from Prime Minister Sir Wilfred Laurier. #nspoli#cbpoli#novascotia
On December 6, 1917, the exhibition building was destroyed by the #HalifaxExplosion. Temporary apartments were built on its grounds soon after, housing approximately 2,200 people.
In 1927 the #Halifax Forum was built on part of the former exhibition grounds. #nspoli#cbpoli

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.
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. #nspoli
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
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.
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.
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. #nspoli#cbpoli#novascotia#capebreton#nshistory
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
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
...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.
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
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
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... #nspoli#cbpoli#novascotia
