Trevali Discovers New High-Grade Mineralized Zones at Santander
Mine
6.7 metres of 12.95% Zn, 0.74% Pb, 2.47 oz/t Ag and 4.47 metres
of 7.45% Zn, 2.85% Pb, 6.30 oz/t Ag
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jun 4, 2014) -
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°) 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.

Note: Channel samples are cut perpendicular to the strike of
mineralized zone 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).

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

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.
