El Cubo is Endeavour’s third and potentially largest mine, located six kilometres southeast of the city of Guanajuato in the state of Guanajuato. Access is by municipal road and infrastructure includes the state power grid, and local labour, supplies and services in the city of Guanajuato. The property covers approximately 8,150 hectares in this second largest historic silver mining district in Mexico.

The El Cubo sub-district is characterized by low- sulphidation epithermal veins typically thousands of metres long, up to 400 metres deep, and ranging up to 15 metres thick. Today El Cubo comprises four underground mining operations feeding a central, 1,550 tonne-per-day plant to produce high-grade silver- gold concentrates, providing employment for 600 employees and 150 contractors.

In 2016, El Cubo produced 2.0 million ounces of silver and 21,327 ounces of gold, totaling 3.6 million ounces of silver equivalent. Silver and gold production exceeded guidance due to higher throughput, partially offset by lower gold recoveries.
