Trevali Further Expands High-Grade Zinc-Lead-Copper Mineralization at Stratmat Deposit, New Brunswick
January 19, 2015
5.7 metres grading 15.89% Zn, 6.97% Pb, 0.54% Cu, 98 g/t Ag, 0.23 g/t Au;
and 35 metres grading 2.36% Cu from newly discovered S5 lens
Vancouver, British Columbia…Trevali Mining Corporation (“Trevali” or the “Company”) (TSX: TV; BVL: TV; OTCQX: TREVF; Frankfurt: 4TI) provides a drilling update for its Stratmat Zinc-Lead-Silver-Copper-Gold deposit in the Bathurst Mining Camp of New Brunswick, Canada where exploration drilling continues to intersect high-grade sulphide mineralization that remains open for expansion.
The Stratmat deposit currently hosts a National Instrument 43-101 compliant Inferred Resource of 5.5 million tonnes grading 6.1% zinc, 2.6% lead, 0.4% copper, 54 g/t silver and 0.6 g/t gold. The most recent drilling within the S-1 Zone and the S-5 Lens has intersected multiple zones of semi-massive to massive sulphide mineralization (Figure 1 and Table 1). These intercepts continue to validate Trevali’s updated and ongoing geologic modeling, the result of the integration of new exploration tools and detailed review of historic data.
ST-786 followed up on a high-grade polymetallic intercept from drill hole ST-752 that was collared earlier in 2014, returning 26.75 metres of 7.42% Zn, 1.37% Pb, 1.26% Cu, 94.2 g/t Ag & 2.45 g/t Au (see TV-NR-14-04, February 26, 2014 for details). Borehole ST-786 intercepted two approximately plus-35-metre thick sulphide horizons within which higher-grade intervals occur (Table 1) including:
- 11.23 metres of 5.14% Zn, 2.19% Pb, 0.62% Cu, 65.4 g/t Ag and 0.89 g/t Au
- 8.70 metres of 5.04% Zn, 2.04% Pb, 0.13% Cu, 45.5 g/t Ag and 0.43 g/t Au
Elsewhere in the S-1 Zone, holes ST-769 and ST-771 targeted and intercepted multiple high-grade intervals in the upper S-1 Zone (Table 1).
Results from drill hole ST-793 continue to expand the size of the S-5 Lens. In addition to 35 metres of massive sulphide grading at 2.4% copper, the hole intercepted multiple high-grade zinc-lead-silver sulphide lenses in the hanging wall to the S-5 body (Table 1 & Figure 2). These hanging wall intercepts are continuous, for example previously released borehole ST-785 returned 4.26 metres grading 10.19% Zn, 4.36% Pb, 0.65% Cu, and 61.36 g/t Ag, and have the potential to define important high-grade massive sulphide zones. The S5 Lens is currently approximately 80 metres in strike length, 160 metres in depth and 15 metres in thickness, and remains open for expansion down-dip to the east.
