B2Gold unveils new PEA for ‘medium-scale’ Gramalote project
Vancouver-headquartered B2Gold has unveiled a new preliminary economic assessment (PEA) for the Gramalote project, in Colombia, outlining a medium-scale operation that marks a shift from previous plans.
The new PEA envisons an openpit mine producing an average of 185 000 oz/y of gold over a 12.5-year lifespan. In the initial five years, the mine is expected to yield 234 000 oz/y at an all-in sustaining cost of $822/oz.
