A village in northern Portugal is fighting to prevent what could be the first large scale battery grade lithium mine in Europe from going into operation on its doorstep. For Assignment, Caroline Bayley travels to Covas do Barroso - the remote farming community with World Agricultural Heritage status and a tiny population - where villagers have formed a protest group which has gained international support. Portugal has one of the largest deposits of lithium in Europe and the Government is in favour of exploiting these resources as part of the green transition as lithium is used in electric vehicle batteries. The mining company needs to lease common land jointly owned by the villagers to access the lithium but the residents are holding out against this, in spite of the compensation on offer. They fear that the four open pit mines would destroy their agricultural way of life. The Barroso mine has been given the green light by Portugal’s environment agency subject to certain strict criteria being met. Owned by Savannah Resources, a London listed company, the mine aims to produce enough lithium for 500,000 electric car batteries a year.
