The Santander project is being developed under an agreement between Trevali and Glencore International, whereby Trevali retains 100% ownership of the project, while Glencore is constructing and will operate a modern 2,000-mt/d mill and flotation plant to produce zinc and lead-silver concentrates. Glencore is also providing project management and operational expertise on a contractor basis to design, develop and operate the future mine using a combination of open-pit and underground mining techniques. Trevali is providing exploration, permitting and community relations for the partnership.

Construction of infrastructure to support underground mining operations at Santander began in July 2011 and was on track to be finished by mid-November. Progress included preparation of the main mine adit, construction of mine offices and trackless equipment maintenance facilities, installation of mine electrical and ventilation systems, and construction of a mine-water treatment facility, a dry and lamp house, a training center, and other ancillary facilities.

The former Santander plant structures and equipment have been rehabilitated and earth-moving and foundation preparation is in ongoing. Construction of a 65.5-km power line to provide power for the project was approximately 60% complete, and construction is under way for the Santander 50-kW main electric substation. The power line and sub-station will connect the Santander project to Peru's national grid.
