- El Cubo is a high-grade, epithermal-vein, underground precious metals mine that has been in operation for almost 200 years.
- From 2012-2019 Endeavour Silver produced 12M ounces of silver and 144,000 ounces of gold from El Cubo.
- Capacity: 45,000 tonnes per month.
The Centrepiece of a Hub & Spoke Mining Strategy.
- El Cubo Mill and Processing Complex.
- Major upgrades completed in 2012 and 2021 (~US$30M in total).
- Processing uses conventional crushing, grinding, flotation and silver-gold concentrate filtration.
Clean. Dry. Organized.

Notes: 1. Silver Equivalent calculated using 1 ounce of gold is equal to 80 ounces of silver. 2. Numbers have been rounded. 3. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves. |

Mineralization
- Classic high-grade, silver and gold epithermal vein system.
- Vein mineralization is normally 1-2 meters wide with mineralized breccia zones of up to 10 meters wide.
- Economic concentrations of silver and gold exist as shoots.
- Several high-grade transverse veins also exist at El Cubo, such as at the Santa Cecilia mine.
- GSilver will mine using a narrow 1.4 meter minimum vein cut-off; this will generate less dilution, less waste, less tailing and less cost per ounce produced.
- The mining method is primarily cut & fill with some resue mining, which allows for selective, non-dilutive mining that focuses on the vein itself.
