0.00%



(otcqx:TREVF)(bvlac:TV) is pleased to announce that its common
shares have been approved for trading on the Main Board of the Bolsa
de Valores de Lima (“BVL”) in Peru and has commenced under the ticker
symbol “TV”. Kallpa Securities S.A.B. in Lima, Peru acted as
Trevali’s advisor for the listing.

“Trevali’s Main Board listing on the Lima Stock Exchange provides
greatly increased investor exposure as the Company is rapidly
advancing both its Halfmile Zinc Mine Project in New Brunswick,
Canada and the Santander Zinc Mine Project in Peru towards
production,” stated Dr. Mark Cruise, Trevali’s President and CEO.
“With the planned purchase of Breakwater Resources Ltd. by Nyrstar NV
announced today for approximately $663 million, Trevali is uniquely
positioned as one of the few remaining near-term zinc-lead-silver
development companies in the Americas. We are pleased to provide
Peruvian and other South American funds, institutions and retail
investors with the opportunity to participate in exciting growth
potential in Trevali’s zinc-lead-silver mine development programs
currently underway and look forward to increasing the shareholder
base throughout Latin America.”

The BVL, along with the Stock Exchanges of Chile and Colombia,
recently launched the Mercado Integrado Latinoamericano (MILA), an
integrated stock exchange of the three countries. The initiative has
created the largest market in Latin America in terms of number of
companies listed and the second largest based on market
capitalization.

Peru is among the world’s top producers of silver, zinc, copper and
gold, copper, silver and zinc and it has an extensive history of
mining and investment in mining. The BVL is one of Latin America’s
most important stock exchanges and mining companies constitute a
significant component of its market. Additional information (in
Spanish) about the BVL may be found at

ABOUT TREVALI MINING CORPORATION

Trevali is advancing two polymetallic deposits to production in
Canada and Peru – the Halfmile and Santander projects respectively.
In Canada, Trevali has the Halfmile and Stratmat polymetallic
deposits near Bathurst, New Brunswick, and the Ruttan copper-zinc
deposit in northern Manitoba. Mine development is underway at
Halfmile with a proposed production at a rate of 2,000-tonnes-per-day
anticipated to commence in 2011. In Peru, the Company has the
Santander zinc-lead-silver mine project and the Huampar silver mine
both located in the Central Peruvian Polymetallic Belt.

At Santander, in conjunction with Glencore International A.G., mine
commissioning and production is anticipated to commence at
2,000-tonne-per-day in late 2011 with full production to follow
immediately thereafter. Additionally through its subsidiary Trevali
Renewable Energy Inc., Trevali is undertaking a significant upgrade
of its wholly-owned Tingo run-of-river hydroelectric generating
facility along with transmission line upgrades and extensions to
allow, in addition to supplying power to the mining operation on the
property, the potential sale of surplus power into the Peruvian
National Energy Grid.

The common shares of Trevali are currently listed on the TSX (symbol
TV). For further details on Trevali, readers are referred to

Such forward-looking statements and information include, but are not
limited to statements as to: the accuracy of estimated mineral
reserves and resources, anticipated results of future exploration,
and forecast future metal prices, anticipated results of future
electrical sales and expectations that environmental, permitting,
legal, title, taxation, socio-economic, political, marketing or other
issues will not materially affect estimates of mineral reserves.

and estimates that, while considered reasonable by the Company, are
inherently subject to significant business, economic, competitive,
political and social uncertainties and contingencies.

These statements reflect the Company’s current views with respect to
future events and are necessarily based upon a number of assumptions
and estimates that, while considered reasonable by the company, are
inherently subject to significant business, economic, competitive,

both known and unknown, could cause actual results, performance or
achievements to be materially different from the results, performance
or achievements that are or may be expressed or implied by such

company has made assumptions and estimates based on or related to
many of these factors. Such factors include, without limitation:

mining,; diminishing quantities or grades of mineral reserves as
properties are mined; global financial conditions; business
opportunities that may be presented to, or pursued by, the Company;
