Sigma-Lamaque is a past producing mine. Integra Mining plans to restart mining operations at the Lamaque deposit, with plans to process ore at the Sigma mill. A Preliminary Economic Assessment (PEA) on the project was published in April 2017. Mine life is estimated at 10 years with two years pre-production. Most of the necessary infrastructure is already in place and hence, pre-production capex of C$175 million is required.
