* Glencore to provide their world-class project management and operational expertise on a contractor-basis to design, develop and operate the future mine using an anticipated combination of open-pit and underground mining techniques thereby enabling the Santander project to reach and maintain optimum concentrate product levels in an efficient manner.

* Trevali will acquire the plant and associated infrastructure over a 4-year period following commercial concentrate production thereby securing full ownership of the new mill and processing complex. Trevali has the right, at any time, to pre-pay the outstanding cost of the plant subject to payment plus 10%.

* Trevali will provide their proven exploration, permitting and community relations expertise on behalf of the partnership in order to fast-track development of the project and expand the known resources that remain open.

* Trevali has secured a Life-Of-Mine concentrate off-take agreement whereby Glencore will buy 100% of the Santander mine production at Benchmark terms.


Debenture Facility

Glencore has also provided a US$2-million credit debenture facility to Trevali of which US$500,000 was previously advanced to help fund the recently completed resource expansion programme. Upon closing the definitive legal agreement as documented above, Trevali elected to draw down the remaining funds that will be utilized to advance exploration and development of the Santander project in addition to fulfilling the Company\'s 18-month budgetary requirements for its Toronto Stock Exchange (TSX) listing application.

The terms of the debenture facility are as follows: Interest payable on an annual basis at LIBOR plus 2.5%; following the second anniversary of the fund draw down, Glencore has the right to convert any outstanding indebtedness into common shares of the Company priced using a trailing 30-day volume weighted average and with a minimum conversion price of Cdn$0.64 per share.

The Company recently received the conditional approval of the Toronto Stock Exchange to list its common shares on the TSX. Listing of its common shares is subject to compliance with all of the TSX requirements, including receipt by the TSX of all required documentation by October 26th, 2010. The Company will notify its shareholders as soon as the date for trading on the TSX has been confirmed. Once listed, the Company\'s common shares will continue to trade under the symbol TV and will be delisted from the Canadian National Stock Exchange (CNSX).
