Marketwired Canada
Trevali Mining Corporation ("Trevali" or the "Company")
(TSX:TV)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) announces that two new zones of
high-grade polymetallic mineralization have been discovered adjacent to the
Magistral Central deposit at its Santander Mine in Peru. The new zones, Fatima
North and Fatima South, occur in the footwall of (or behind) the principal
Magistral Central deposit and remain open for expansion to the East and at
depth.
The Fatima Zones trend sub-perpendicular (approx. 80-85 degrees ) to the main
Magistral Central deposit, and similar to the Rosa Zone are thought to represent
a later phase of high-grade replacement mineralization along a set of roughly
East-West trending feeder structures/veins (Figures 1 & 2).

Located in the footwall and within / subjacent to the existing underground
development, the Fatima zone is readily accessible for incorporation into the
Santander mine plan. The Company has mobilized an underground drill rig to site
and it is about to commence a 4-5,000 metre drill campaign to further explore
and define the newly discovered Fatima and Rosa zones (Figure 3). In addition
the drilling will provide deeper, in-fill definition information on the deposits
in order to facilitate long range mine-planning.

and therefore reported intervals represent the true width of base metal
mineralization exposed in the drift.

EXPLORATION MODEL
The successful discovery of the Rosa and Fatima zones coupled with their
interpretation to represent a later phase of high-grade feeder mineralization is
indicative of a large-to-very-large, long-lived Carbonate Replacement Deposit
("CRD") system at Santander.
Of note is the fact that the Rosa and Fatima zones trend towards the Company's
Puajanca South deposit and Puajanca North prospect where sampling has returned
bonanza grade silver mineralization of up to 1.2 metres wide grading 39.9 oz/ton
(1,369 g/t) Ag, 83% Pb and 18.4% Zn within an aggregate of 1.45 km of North East
to East-West trending veining that averages 1 metre wide and returned 5.3 oz/ton
silver (182.7 g/t), 14.3% lead and 2.0% zinc (Figure 4). Metal ratios (lead
values significantly higher than zinc), mineral system analysis and alteration
assemblages in the area are interpreted to indicate that structures in the
Puajanca zone are located in the uppermost portions of a 'fertile' and well
preserved polymetallic mineralizing system (see January 5, 2011 news release
TRC-NR11-01 for details).
All mineralization to date is spatially associated with a significant
geophysical anomaly interpreted to represent a large magmatic system which
drives the high-level CRD mineralization discovered to date on the property
(Figure 4). These most recent discoveries of Rosa and Fatima further highlight
the overall exploration potential of the Santander property and of the Magistral
- Puajanca corridor in particular (Figure 4).

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

(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

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.
