TV-T Trevali Reports Additional Drill Results From New Oyon Zone at Santander Zinc Mine
VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 2, 2016) - Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) announces results from four new drill holes of its ongoing 2016 underground exploration drill program at the Santander zinc mine in Peru. The aim of the current drilling is to test recently discovered mineralization in the hanging wall of the Magistral North deposit. Drill holes continue to intersect multiple stacked mineralized massive sulphide replacement zones, or mantos, both within the main Magistral North body as well as in the newly discovered Oyon mantos (Table 1). The intercepts are near existing mine infrastructure and will be quickly incorporated into the near-term (2016-2017) mine plan. Mineralization in both the Magistral North deposit and the new Oyon mantos remains open for expansion and further underground drilling is in progress (Figure 1).

MAGISTRAL NORTH AND OYON ZONES
This latest follow-up expansion-definition drilling program continues to define additional mineralization in the Oyon mantos, located in the hanging wall to the main Magistral North deposit (Figure 1).
As presently defined the Oyon zone contains multiple stacked lenses (or mantos) of replacement semi-massive to massive sulphide mineralization and associated veining that varies from 1 to plus-10-metres thick, a modeled strike length of approximately 100 metres and a currently defined dip length of approximately 180 metres.
In general, average grades for all key metals (Zn, Pb and Ag) are significantly higher than current Santander mill feed grades (Table 1). Zinc to lead/silver metal ratios remain high, in the 1:1 to 2:1 range, which is suggestive of the upper to mid-portions of the mineral system and is interpreted to suggest significant additional depth potential remains. Initial targeting suggests that similar style (Pb-Ag rich) mineralization may exist in the hanging wall of the Magistral Central deposit. The Company cautions that additional drilling is required to further test this hypothesis.
The mantos are proximal-to-immediately-adjacent to the main Magistral North deposit and close to existing and future planned mine development. Consequently minimal additional work will be required to begin adding value (feed) to the Santander mill. Both the Magistral North Zone and emergent Oyon Mantos remain open and expansion/definition drilling 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.
