ABOUT TREVALI RESOURCES CORP.

The Company in conjunction with its prospective partner, Glencore International A.G., is continuing to work through the terms of a definitive development agreement for the Santander silver-lead-zinc project in west-central Peru that will, if concluded, see Glencore provide and operate on the property, a 2,000-tonne-per-day concentrate plant, undertake mining operations on a 'contractor/toll basis' and enter into a long-term concentrate offtake agreement with the Company for 100% of the Santander project's production at benchmark terms.
