Hello guys, just wondering if anyone could direct me to an article or post about the copper-bearing tourmaline mining operations in mozambique. Just need a little info on their methods, as I am struggling to find anything with much info. Thx

It also has a lot of links to other relevant articles in at the bottom of page.
Interestingly, Cuprian Tourmalines were being mined in situ and sold between 1969-75 but the mines were lost after the owners were forced to leave when the country gained independence in 1975. At that time the Tourmalines had not been identified as cuprian, this is not documented until 2004 and the identification of their copper content in alluvial stones can be loosely attributed to Moses Konate of Mozambique Gems.
I have some of the original crystals found in situ and a client/friend of mine who was there at the time has a neon green-blue crystal that is over 600ct and about 90% eye-clean.
