Metminco's underground-only Miraflores proves up

A scoping study into the Miraflores gold and silver project, in Colombia, has found that an initial capital spend of $81-million would be required to develop a four-million-tonne-a-year underground-only operation. Based on the expected mined grade of 3.51 g/t gold and 2.84 g/t silver, the project would produce around 50 000 oz/y of gold, over a mine life of nine years.
