There are many types of minerals which are mined in Canada. Four of them are iron, salt, gold, and sulphur.
Virtually all the gold, silver and copper was mined in Salt Lake County, Utah in the U.S.
It's hard to believe, but if all the gold ever mined was weighed, it would amount to between 140,000 and 160,000 tons. That would be a cube of approximately 62 feet on a side. A cubic inch of gold weighs 11.06 oz.

I heard on NPR last year that the total amount of all the gold ever mined would fill two Olympic swimming pools. But I bet this answer will be much harder to find for diamonds. Diamonds are most likely not as rare as they are purported to be. They are used industrially on a much wider scale than industrial uses of gold.
There's really no way of knowing, because we don't know exactly how much gold that is still underneath the ground (or exactly where it is, or we'd go get it)!
Yes there would, if there is gold in the ground now there would have been gold in the ground then (the middle ages weren't that long ago!) Because gold reacts slowly, if at all, the gold that is on the earths surface now would have been there then. BUT not all the gold was mined, so in answer to your question, yes there were mines but different to the ones of today.
Five minerals mined from the Earth are gold, silver, copper, iron ore, and coal.
Since 2007, China has led the world in gold production, overtaking South Africa, whose mines have produced as much as 50% of all gold ever mined in the world.
Gold is scarce. It is durable. More than 95 percent of all the gold ever mined during the past 5,000 years is still in circulation. It is inherently valuable because of its beauty and its usefulness in industrial and decorative applications.
It is rare, all mined gold in the world can fit into two olympic size swimming pools.
In British Columbia, mining activities primarily focus on minerals such as copper, gold, silver, zinc, coal, and molybdenum. The province is also known for its significant production of industrial minerals like limestone, granite, and aggregate materials.
