Trevali Expands High-Grade Zinc-Lead-Silver Mineralization at Santander Zinc Mine and Discovers New Central-Oyon Zone

VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 21, 2016) – Trevali Mining Corporation (TSX:TV) announces results from twelve new drill holes of the ongoing 2016 underground exploration drill program at its Santander Zinc Mine in Peru. The aim of this current phase of drilling is to further extend the down-depth expression of the Magistral Central deposit and associated Fatima vein zones, in addition to test for the potential presence of hanging-wall hosted “Oyon” mineralization similar to that discovered at Magistral North early this year (see TV-NR-16-09 for details). The program has been hugely successful on all counts with the drill holes intersecting and extending both the Magistral Central and Fatima zones in addition to discovering new massive sulphide replacement mineralization in the hanging-wall to the Magistral Central deposit.
In excess of 90% of the holes returned zinc grades, over mineable intervals, materially higher than those in current mining operations where run-of-mine head grades typically range from approximately 4-4.5% Zn (Table 1). All mineralization remains open for expansion and further underground drilling is in progress.
“These latest results from our successful ongoing 2016 exploration drill program remain highly encouraging and continue to add very tangible, near-term value to the Santander Zinc Mine where our experienced operations team has a proven track record of translating exploration successes into mill feed in a timely manner,” stated Dr. Mark Cruise, President and CEO of Trevali.
