| In a few rare spots of the world, gold is literally just in the dirt and rocks. There's certainly some gold in the UK; there's still probably thousands of extractable tonnes of gold in the UK. Whether a deposit is economic to extract is a different question. Very few sites in the world can compete with the gold mines of Canada, China and Australia with their very rich deposits. > Was it all relatively surface level and rapidly mined out, and now all gone? To some degree this is a factor. Copper and tin are other resources you'll find are already heavily extracted in Europe: > The main mining district of the Kupferschiefer in Germany was Mansfeld Land, which operated from at least 1199 AD, and has provided 2,009,800 tonnes of copper and 11,111 tonnes of silver. The Mansfeld mining district was exhausted in 1990. It's not so much that they literally ran out - there's still plenty of copper there. But it was only viable to run in the East German (Communist) economy. Now that most is extracted, there are diminishing returns. It takes more labour and processing and etc. than extracting from a deposit elsewhere would. When Europeans came to North America and reached regions that had never had a particularly high population density and had never had much mining - like in parts of the Rocky Mountains - they sometimes literally found gold dust lying at the bottom of riverbeds and chunks of gold ore sticking out of the side of cliff-faces. (Cue up a gold rush.) Europe's first large-scale miners probably had a similar experience of abundance once, many thousands of years ago. |
