Trevali Significantly Expands Rosa Lead-Silver-Zinc Zone at the
Santander Mine in Peru
Highlights include - 9.7 metres at 4.8 oz/ton (163.1 g/t) Ag,
7.89% Pb, 8.29% Zn and 30.69 metres at 2.3 oz/ton (78.1 g/t) Ag,
3.86% Pb and 4.01% Zn
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 10, 2013) -
Trevali Mining Corporation
(TSX:TV)(OTCQX:TREVF)(LMA:TV)(FRANKFURT:4TI) ("Trevali" or the
"Company") announces results of three additional holes drilled on
the deeper levels of the newly discovered Rosa Zone at its
Santander Mine in Peru. All three diamond drill holes have
intersected significant high-grade lead-silver-zinc mineralization
at depth, further expanding the size of the Rosa Zone. Drilling
also intersected a sub-parallel replacement or Manto zone that also
returned high lead and zinc values over potentially mineable
intervals. All mineralization remains open for expansion at
depth.
Drill holes assays are listed in Table 1. A 3-D view section
showing the location of the drill holes and mineralized zones is
shown in Figure 1.
Multi-phase lead-silver rich polymetallic mineralization
cross-cuts and overprints the Magistral North deposit and thins to
the East towards the relatively impervious or 'tight' Pariatambo
Formation. Based on detailed underground geological and structural
mapping, channel sampling and drill hole intercepts, the Rosa Zone
is a wedge shaped body in three-dimensions, thickening at depth and
to the West. It is currently up to 100 metres in length (along
strike), 3-to-15 metres in width and extends for more than 200
metres in depth. Additionally, newly discovered replacement or
manto mineralization over potentially mineable intervals was
intersected sub-parallel to and approximately 30 metres due north
of the Rosa Zone - its significance is currently not fully
understood and more drilling is required.
Mineral system analysis and interpretation suggests very
considerable depth potential given the very high lead-silver to
zinc and pathfinder element ratios. Globally such complex
polymetallic relationships are typically indicative of larger,
robust, and well developed carbonate replacement systems.

Qualified Person and Quality Control/Quality Assurance
EurGeol Dr. Mark D. Cruise, Trevali's President and CEO and M.
Dayle Rusk, P.Geo., Trevali's Director, Geology, are qualified
persons as defined by NI 43-101, have supervised the preparation of
the scientific and technical information that forms the basis for
this news release and are responsible for all aspects of the work,
including the quality control/quality assurance programs. Dr.
Cruise is not independent of the Company, as he is an officer,
director and shareholder. Ms. Rusk is not independent of the
Company as she is an officer and shareholder. On-site personnel at
the project rigorously collect and track samples which are then
security sealed and shipped to ALS Laboratories (ALS), Lima, for
assay. ALS's quality system complies with the requirements for the
International Standards ISO 9001:2000 and ISO 17025: 1999.
Analytical accuracy and precision are monitored by the analysis of
reagent blanks, reference material and replicate samples. Quality
control is further assured by the use of international and in-house
standards. Blind certified reference material is inserted at
regular intervals into the sample sequence by Trevali personnel in
order to independently assess analytical accuracy. Finally,
representative blind duplicate samples are routinely forwarded to
ALS and an ISO compliant third party laboratory for additional
quality control.

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

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,

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.
We advise US investors that while the terms "measured
resources", "indicated resources" and "inferred resources" are
recognized and required by Canadian regulations, the US Securities
and Exchange Commission does not recognize these terms. US
investors are cautioned not to assume that any part or all of the
material in these categories will ever be converted into
reserves.
This news release does not constitute an offer to sell or a
solicitation of an offer to buy any of the securities in the United
