An AIM quoted miner will set out its stall today as the lowest cost producer of uranium needed to feed the world’s growing number of nuclear reactors. Berkeley Energia, which aims to begin construction of its Salamanca mine in northwestern Spain next year, will announce the results of additional work on its Zona 7 deposit, which it says will enable it to bring down operating costs by 40 per cent, making it a lower cost producer than the Toronto listed Uranium One. The mine also would give Europe’s 160 reactors, which rely almost entirely on imports, chiefly from Kazakhstan, Russia and Niger, a source of uranium on their doorstep.
