Guyana Goldfields owned and operated the Aurora Gold Mine in the Cuyuni-Mazaruni region, along the Cuyuni River, of Guyana. Guyana Goldfields oversaw its development in 2014–15. While they produced 35,901 ounces of gold in 2015, commercial production began in January 2016. The mine produced 151,600 ounces in 2016 as the company again transitioned to a company focused on mine operation. During 2017, 160,500 ounces were produced, 150,450 ounces were produced in 2018 and 124,200 in 2019. It is an open pit mine that uses a semi-autogenous mill and carbon in pulp processing. The company's March 2020 updated life of mine plan estimated 2.2 million ounces of proven and probable reserves where the gold is dispersed at an average 2.7 grams per tonnes of ore. The plan estimated a 14-year mine life assuming the transition to underground mining can be achieved.
