VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 25, 2015) - Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) announces results of five drill holes from its 2015 exploration program designed to test the deeper levels of the Fatima and Magistral Central zones at its Santander Zinc Mine in Peru. All five drill holes intersected significant lead-silver-zinc mineralization and remain open for expansion:

"The Company continues to be pleased with the exploration results from our Santander mine. The exploration success rate to date is extremely high, but more importantly given current market conditions, the Santander team has been able to successfully convert exploration success into value by adding mill feed in highly-compressed timeframes," stated Dr. Mark Cruise, President and CEO of Trevali. "Bigger picture, we believe we have barely scratched the surface at Santander, which geologically is already one of the larger-end members of the Carbonate Replacement Deposit type. All of the currently known zones, including the former-producing Santander Pipe, remain open for expansion and we have multiple earlier-stage priority targets on our large property package that require future drill testing."

FATIMA ZONES

Discovered in 2014, the Fatima North and South zones trend sub-perpendicular (approximately 80-85°) to the main Magistral Central deposit. Fatima North is currently better defined and has dimensions of approximately 60 metres (east-west), ranges from 5-to-15-metres wide and extends at least 150-metres down-dip where it remains open. Fatima South is the smaller sibling (from 2-to-3-metres wide) but is higher grade and appears to converge towards Fatima North at depth. For example, drillhole FA-118-15 was designed to test the down-dip extension of the Fatima zone where it was interpreted to intersect the main Magistral Central deposit and resulted in the intersection of a particularly broad zone of massive sulphide mineralization (Table 1 & Figure 2).

Analogous to the Rosa zone at Magistral North, the Fatima zones are interpreted to represent a later-stage overprinting phase of lead-silver rich replacement mineralization along a set of roughly east-west trending feeder structures/veins that trend towards the Company's nearby Puajanca prospect. The results suggest that Fatima North and South may merge at depth to potentially form a single large mineralized area however the Company cautions that additional drilling is required to test this hypothesis (Figures 1 & 2).

Located in the footwall and subjacent to the existing underground development, the Fatima zones are readily accessible for incorporation into the current Santander mine plan. Initial mining from Fatima commenced in Q2 of this year with modest production from this new zone to date.

MAGISTRAL CENTRAL

These most recent drill hole intercepts from the down-dip extension of Magistral Central suggests that mineralization width and grade is increasing at depth with multiple replacement zones intersected in several of the drill holes (Table 1). Prior to this, the Magistral Central zone returned relatively modest Pb and Ag values however silver-bearing galena was intersected in drill holes SAN 205 and 207 with values of up to 5.8% Pb and 9.85 oz/ton Ag returned. These may represent the (offset) down-dip extension of the Fatima zones and/or the upper portions of an as yet undiscovered new "feeder" zone.

Drill holes SAN-206 and SAN-208 (assays pending) are interpreted to indicate that the Magistral Central and Magistral South zones may merge into a single zone at depth. The area sits above and is spatially associated with a very large, strong geophysical anomaly (Down-Hole Electromagnetic anomaly approximately 300-by-300 metre modelled conductive plate) that extends at least an additional 150-200 metres deeper than current drilling and remains open to the north, south, east and at depth.

Drilling from both surface and underground is ongoing.

Drill core samples were processed and assayed in the Santander mine onsite laboratory. Zinc, lead and silver, assays were obtained by Aqua-Regia dissolution followed by Atomic Absorption measurement. Values of lead and zinc over 15% are assayed by volumetric method. 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. The onsite laboratory is outsourced and managed by SGS-Peru personnel. SGS-Peru's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Finally, representative blind duplicate samples are routinely forwarded to an ISO compliant third party laboratory for external quality control.

Trevali's production plan at the Caribou Mine is based only on measured, indicated and inferred resources, and not mineral reserves, and does not have demonstrated economic viability. Trevali's production plan at the Santander Mine is based only on indicated and inferred mineral resources, and not mineral reserves, and does 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.
