Brazil to resume uranium exploration
Uranium has been mined in Brazil since 1982, but the only operating mine is INB's Lagoa Real/Caetité mine, with a capacity of 340 tU per year. The mine has known resources of 10,000 tU at 0.3%U. INB commenced developing the adjacent Engenho mine in January 2017, a 200-300 tU per year open pit operation.
