Effective Reserving Solution

Modelling using Maptek Vulcan™ gives El Peñón confidence in thein situ reserves generated for long-term mine planning.

Yamana Gold owns a high grade underground gold-silver mine in northern Chile, 160 km from Antofagasta. El Peñón is a low-sulphide epithermal deposit with mineralisation hosted in veins and hydrothermal breccias.

The mining method is split blasting by benching and filling, where an excavation allows ore to be extracted between two previously developed sublevels (drifts).

An updated representative solid resource model is fundamental to determination of reserves and the subsequent development of long-term mining plans.

• Saving of approximately 400 effective work-hours
• Major time-saving in measuring depletion of the deposit
• High precision results provide an accurate resource evaluation
