In March, the company updated the prefeasibility study for its Metates gold-silver project in Mexico’s Durango State, which envisaged a 30,000 tonnes-per-day open-pit operation scaling up to 90,000 tonnes-per day after four years of mining, eventually becoming a 27-year mining operation, followed by 10 years of processing low-grade stockpiles. The study calculates an after-tax net present value of US$737.4 million at 5% discount and a 7.7% after-tax internal rate of return.

In September 2014, Gold Reserve negotiated a US$740-million settlement with the government for losses it incurred after the government rescinded permits and licenses for the company’s Brisas gold-copper project in southeastern Venezuela as part of a nationalization drive.
