Cornish Tin: The Great Wheal Vor Project
Cornish Tin Limited is a Cornwall based mineral exploration company, advancing The Great Wheal Vor Project, near Breage, Cornwall. It has rights to explore for and extract all minerals and aggregates including tin, lithium, copper, tungsten, and geothermal energy.
This group of 26 former producing mines, last operated in the 1800s, were described in 1929 as
"the richest in tin of all the Cornish mines, probably the richest tin mine which has ever been worked in the world." Historic production grades were high, averaging approx 3.5% tin, and peaking at over 5.5% tin. Even assuming a current production grade of only 2% tin this would be one of the top 3 tin mines by grade in the world if being mined today.
