When it re-opens, South Crofty becomes the only functioning tin mine in Europe (excluding Russia). or North America. However, the revival will require more time and investment. Three hundred meters underground, the company has to overlook and drain hundreds of miles of tunnels.
In addition, hundreds of people have to be recruited to work in the underground, which could be a difficult task in an area where many people live have moved to office jobs and jobs in the service and tourism industries. However, Cornwall continues to educate mining engineers and geology experts at the Camborne School of Mines Penryn.
"There are many ex-graduates who came from Camborne who were actually trained in South Crofty and now practice their craft around the world," Williams said. "But many of them still live in Cornwall, and I'm sure many of them would like to return and work at South Crofty instead of traveling internationally."
"It would be great to see [a revival]," said Mark Camp, spokesman for Visit Cornwall and tour guide for historic mining in Cornwall. "Cornwall now relies on tourism for much of its income, so it would be great to see how mining returns."
Strongbow exploration, which also explores the potential for lithium mining in Cornwall, said the mine will provide 275 jobs in create the region. The decline in the British pound since the Brexit referendum in 2016 means that Cornish minerals can compete again on world markets .
"In our eyes, this is Brexit proof," Williams said. "One of the points that we make to the Cornwall Council, and especially the United Kingdom, is that you can not move a tin deposit."
Although tin mining is not returning to Cornwall on a large scale, tourism, inspired by the county's industrial past, is expected to further boost the economy. Approximately 4.5 million visitors flock to the peninsula every year, and the number of visitors to historic mines is increasing, thanks also to the BBC drama Poldark and the designation of the pewter coast as a UNESCO World Heritage Site in 2006.
Families that have operated for decades from the mining industry Can swung into tourism.
Mark Wills, owner of Blue Hills Tin, a mining and tin jewelry store visitor center, said his father was the last of four generations to work underground.
"When the [tin] price fell in the late 1980s, wholesale sales were no longer profitable, so we gradually renovated some old machines on site and started to sell them ourselves," he said ,
Today, Blue Hills Tin attracts visitors from around the world who are interested in the history of 4000-year-old tin production.
"It really stimulates the imagination," Wills said. "Whether people are only interested in the architecture of the buildings or in the physical processes that the mineral has to go through."
Strongbow's research suggests that South Crofty has some of the highest grade cinders in the world. Cornwall's imprisonment with tin could not just be a thing of the past.
