Trevali discovers New High-grade zinc-lead-silver Mineralization at the Santander Zinc Mine

Trevali Mining Corporation (TSX:TV) announces results from three diamond drill holes that are part of the ongoing 2016 underground exploration drill program at its Santander Zinc Mine in Peru. The aim of the current phase of drilling is to extend the down-dip expression of the Magistral Central (MC) zone, to test between Magistral North (MN) and MC zones in addition to test for the potential presence of hanging-wall hosted “Oyon” mineralization.

Drill hole MC-181 targeted the area between MC and MN at the 4370 level where geological modeling indicted the presence of a high priority target. The sub-horizontal drill hole intersected 3.15 metres of high-grade Pb-Ag-Zn mineralization followed by 3.8 metres of high-grade Zn-Ag mineralization at approximately 94 metres downhole for an aggregate true thickness of 6.95 metres (Table 1). This exceptionally high-grade replacement mineralization remains open for expansion and step-out drilling is in progress (Figure 1 & 2).

In detail, the mineralization is proximal to existing mine workings (just 95 metres from the main 4370 level) and readily accessible. Approximately 200 metres below MC-181, two drill holes (MC-179 and MC-180) intercepted new, narrow polymetallic mineralization which effectively links the Magistral bodies at these levels, and co-insides with the upper portion of the 2011 downhole geophysical anomaly that extends to depth (Figure 1 and see News Release dated October 24, 2011 for details).

(i)True widths of the mineralized intervals are estimated between 75-100% of core length.
