The Cisneros project is a high-grade gold mine located in Antioquia, Colombia, by Antioquia Gold. It comprises nine deposits with initial gold produced from the Guaico and Guayabito deposits.

Construction of the Cisneros mine started immediately after obtaining the environmental licence for the Guaico deposit in October 2015. The final permit for construction and mining was received in November 2016, following the grant of environmental licence for the Guayabito deposit.

First gold production at Cisneros was achieved in March 2019.

Antioquia Gold is expected to produce between 30,000oz and 40,000oz of gold a year during its initial mine life of six years.
