Trevali Achieves Commercial Production at Santander
Trevali announced production guidance for Santander during 2014 at 42 million to 45 million lb of zinc, 15 million to 17 million lb of lead, and 700,000 to 720,000 oz of silver in zinc and lead-silver concentrates. Mill throughput for 2014 is estimated at 670,000 to 690,000 mt, with average head grades estimated at 4.0% to 4.2% zinc, 1.5% to 1.7% lead, and 1.4 oz/mt to 1.6 oz/mt silver.
The underground Santander mine is located about 200 km by road northwest of Lima. The project is being developed under an agreement between Trevali and Glencore International, whereby Trevali retains 100% ownership, while Glencore has built and is operating the processing plant to produce zinc and lead-silver concentrates. Glencore is also responsible for supervision of the contract mining operations and has entered into a long-term concentrate offtake agreement for 100% of Santander’s concentrate production.
With Santander now in commercial production, Trevali has shifted its development focus to its New Brunswick operations in Canada, where it is preparing the Caribou mine and mill complex for startup.
