NEW BRUNSWICK – Exploration drilling done by Vancouver-based Trevali Mining at the Caribou zinc project in the Bathurst Mining Camp has intersected 50.9 metres of massive sulphide mineralization outside the current resource limits.
Hole BR-1014A intersected the new mineralization at a vertical depth of roughly 550 metres below the surface. The 50.9-metre intersection graded 5.08% Zn, 1.76% Pb, 0.37% Cu, 59.66 g/t Ag, and 1.63 g/t Au. Several higher grade intervals within the 50.9 metres including 5 metres of 7.28% Zn, 2.41% Pb, 0.38% Cu, 82 g/t Ag and 2.09 g/t Au. Immediately underlying this interval was a thin copper-rich lens grading 1.4% Cu, 0.8% Zn, 24.65 g/t Ag and 0.2 g/t Au over 2.3 metres that may represent a local “feeder” source, according to Trevali. The intervals are estimated at 65 to 70% of true thickness.
At the end of 2014, the Caribou resource (5% Zn cut-off) comprised 7.23 million measured and indicated tonnes averaging 6.99% Zn, 2.93% Pb, 0.43% Cu, 94.43 g/t Ag, and0.89 g/t Au. There were also 3.66 million inferred tonnes grading 6.95% Zn, 2.81% Pb, 0.32% Cu, 78.31 g/t Ag1, and.23 g/t Au.
