Discovery of massive sulfides at Caribou Zinc mine

Published by , Assistant Editor
Global Mining Review,

Trevali Mining Corp. has announced the latest results from its 2017 exploration campaign at the Caribou Zinc mine in the Bathurst Mining Camp of New Brunswick, Canada. Directional exploration drilling has defined a major body of massive sulfide mineralisation containing significant zinc-rich polymetallic intervals. As presently defined, the zone is centred approximately 350 m from the currently defined deposit and remains open for expansion.

In 2015, the first hole into the north limb extension was reported, BR-1014A - intersected 50.9 m grading 5.08% Zn, 1.76% Pb, 0.37% Cu, 59.66 g/t Ag and 1.63 g/t Au. The intercept was interpreted to highlight the excellent continuity of mineralisation along the prospective "Caribou Horizon" and was a significant step out beyond the 2014 resource base.

The 2017 exploration programme was designed to follow-up and better define and expand this zone of mineralisation: Drilling to date has defined two lenses of massive sulphide mineralisation which vary from 5-to-plus-30 m thick and have a currently modelled strike length of approximately 450 m and a dip length of approximately 700 m, within which higher-grade ‘Run-Of-Mine’ mineralisation occurs.

Mineralisation as presently defined, is adjacent to mine infrastructure, effectively doubles the strike length of the North Limb of the Caribou deposit and remains open for expansion. The current 2017 inferred resource drilling programme is scheduled to be completed by mid-December, with additional drill results and resource estimates to be announced in the first quarter of 2018. Potential extensions to the East Limb remain to be tested in 2018.
