operations at the Caribou Mine/Mill Complex," stated Mark Cruise, Trevali's
President & CEO.


The Company will incur Canadian exploration and development expenses (as defined
in the Income Tax Act (Canada)) in an amount equal to the gross proceeds raised
from the Flow-through Shares no later than December 31, 2014 and will renounce
such expenses effective December 31, 2013 and such expenses will qualify as
"flow-through mining expenditures" within the meaning of the Income Tax Act
(Canada).The gross proceeds from the sale of the Flow-Through Shares will be
used to fund continued underground development and exploration infrastructure at
the Halfmile Mine and exploration expenditures at the Stratmat Deposit.

This news release contains "forward-looking statements" within the meaning of
the United States private securities litigation reform act of 1995 and
"forward-looking information" within the meaning of applicable Canadian
securities legislation. Statements containing forward-looking information
express, as at the date of this news release, the Company's plans, estimates,
forecasts, projections, expectations, or beliefs as to future events or results
and the company does not intend, and does not assume any obligation to, update
such statements containing the forward-looking information. 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. 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, 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, political and social uncertainties
and contingencies. Many factors, 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 forward-looking statements contained in this news release and the company
has made assumptions and estimates based on or related to many of these factors.


Such factors include, without limitation: fluctuations in spot and forward
markets for silver, zinc, base metals and certain other commodities (such as
natural gas, fuel oil and electricity); fluctuations in currency markets (such
as the Peruvian sol versus the U.S. dollar); risks related to the technological
and operational nature of the Company's business; changes in national and local
government, legislation, taxation, controls or regulations and political or
economic developments in Canada, the United States, Peru or other countries
where the Company may carry on business in the future; risks and hazards
associated with the business of mineral exploration, development and mining
(including environmental hazards, industrial accidents, unusual or unexpected
geological or structural formations, pressures, cave-ins and flooding); risks
relating to the credit worthiness or financial condition of suppliers, refiners
and other parties with whom the Company does business; inadequate insurance, or
inability to obtain insurance, to cover these risks and hazards; employee
relations; relationships with and claims by local communities and indigenous
populations; availability and increasing costs associated with mining inputs and
labour; the speculative nature of mineral exploration and development, including
the risks of obtaining necessary licenses and permits and the presence of laws
and regulations that may impose restrictions on 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; the Company's ability to complete and successfully integrate
acquisitions and to mitigate other business combination risks; challenges to, or
difficulty in maintaining, the Company's title to properties and continued
ownership thereof; the actual results of current exploration activities,
conclusions of economic evaluations, and changes in project parameters to deal
with unanticipated economic or other factors; increased competition in the
mining industry for properties, equipment, qualified personnel, and their costs.
Investors are cautioned against attributing undue certainty or reliance on
forward-looking statements. Although the Company has attempted to identify
important factors that could cause actual results to differ materially, there
may be other factors that cause results not to be as anticipated, estimated,
described or intended. The Company does not intend, and does not assume any
obligation, to update these forward-looking statements or information to reflect
changes in assumptions or changes in circumstances or any other events affecting
such statements or information, other than as required by applicable law.


Trevali's production plans at Caribou-Halfmile-Stratmat and Santander are based
only on Indicated and Inferred Mineral Resources and not Mineral Reserves and do
not have demonstrated economic viability. Inferred Mineral Resources are
considered too speculative geologically to have the economic considerations
applied to them that would enable them to be categorized as Mineral Reserves,
and there is therefore no certainty that the conclusions of the production plans
and Preliminary Economic Assessment (PEA) will be realized. Additionally where
Trevali discusses exploration/expansion potential, any potential quantity and
grade is conceptual in nature and there has been insufficient exploration to
define a mineral resource and it is uncertain if further exploration will result
in the target being delineated as a mineral resource.
