With gold production ramping up at Segovia following the commissioning of the second mill and construction advancing at the Marmato Bulk Mining Zone, we remain focused on doubling our annual gold production to more than 500,000 ounces while advancing the Soto Norte and Toroparu projects – catalysts that support our longer-term growth and our vision to create a leading gold mining company in Latin America,” Woodyer said.
