journey by ferry that we used to get there, we've looked at one of the toughest hikes I've ever taken for a bird's eye view of the sound, and a look at some of the engineering required to live in a vertical place.
The mine was certainly productive, however. During the 70 years the mines operated, ore totals included 650,000 tons of copper, 137,000 tons of zinc, 17,000 tons of lead, 500 tons of cadmium, 188 tons of silver, and 15.6 tons of gold. The gold alone would be worth $750 million at current prices. My rough calculation of the price of the copper the mine produced is $3.4 billion.
They also demonstrated the carbide lamps that were used for lighting in the mines for many decades (above). Better than candles, certainly, but I would want some bright flashlights, and a bunch of them. Being lost in a totally dark mine (or cavern) is one of my serious phobias.
They allowed us to wander a little bit around the ground floor of the mill, and I was able to pick out something sort of unique. In the wet environment, copper carbonate stalactites have formed on some of the girders!
All in all, a great experience. If you are ever in Howe Sound, consider the tour at the Britannia Mine. Information can be found at https://www.britanniaminemuseum.ca/.
