Geizer Hill, the other side of hwy 102 from #BayersLake, was forested back then. An article in the Feb. 1898 edition of Canadian Mining Reviews even described it as being “about three miles from Halifax,” a reminder of how much #Halifax has grown over the past century. #nspoli
According to the article, “a trial run of one ton [of ore] gave six penny weights, eight grains." One penny weight is 1.5 grams so this test of the ore produced about 9 grams of #gold, or a 1/3 of an ounce. #nspoli#cbpoli#novascotia#capebreton#nshistory
According to a January 18, 1898 story in the Mail Star newspaper, Alexander Taylor claimed to have found #gold-bearing quartz all over his land on Geizer Hill and that he had hundreds of tons of quartz ready for the crusher. #nspoli#cbpoli#novascotia#capebreton#nshistory
A January 25, 1899 story in the Mail Star said there were many prospectors on Geizer Hill and some had found #gold. Some were excavating near a Mr. MacDonald’s house and they reportedly found gold-bearing quartz. #nspoli#cbpoli#novascotia#capebreton#nshistory
According to the Fairview historical Society, in the 1930s Hubert Smart said prospectors dug holes all over the Rufus Avenue vicinity in a search for #gold. He said he worked there himself, blasting and drilling. #nspoli#cbpoli#novascotia#capebreton#nshistory
In the modern era, #gold mining returned to #Halifax - well, Halifax Regional Municipality - when the #MooseRiver mine opened in 2017. It employs 300 people and is providing an essential material we all use every day (it's in the device you're using now!) #nspoli@SeanFraserMP
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
