Plaque Text

Cobalt played a decisive role in the evolution of hard-rock mining in Canada. Between 1903 and the 1920's, the district's rich veins triggered a mining boom which attracted international attention and led to Cobalt's emergence as the silver capital of the world. The history of the industry is written in the surrounding landscape. Open-cuts carved from the rock by hand reflect the earliest surface mining operations. Mining shafts, sunk as operations expanded, are marked by the presence of headframes. Concrete foundations, massive rockpiles and remnants of tailings indicate the location of milling facilities for processing ore on site. Cobalt's former prosperity is still visible in the substantial commercial and financial buildings dominating the town centre. Ultimately, the operations at Cobalt established a cadre of mining professionals and a pool of capital, which sparked further mining exploration and proved invaluable in the development of large-scale gold and copper mining in Ontario and Quebec.
