Trevali Mining to Implement Sandvik Underground Mining Fleet at Caribou Zinc Mine

Trevali Mining Corporation announces it has received initial delivery of part of its new Sandvik underground mining fleet for the Caribou Zinc Mine in the Bathurst Mining Camp of northeastern New Brunswick.

Components of the new fleet, specifically new haul trucks and loaders, have arrived as scheduled and are currently being transitioned into operations where they are expected to deliver higher availability and production performance upon integration (Figure 1).

As part of a site-wide optimization initiative, the new underground mining fleet for the Caribou Zinc Mine is an approximately Cdn$20-million investment through a partnership with Sandvik Mining that will supply and maintain a full fleet of mining equipment for Caribou operations. This initiative and transition to owner-operated status is expected to deliver safer and more productive operational capabilities and significant savings in overall Caribou operating costs.

Currently there are three loaders and four TH540 trucks onsite at Caribou as part of this initial equipment delivery. Additional components of the new Sandvik underground mining fleet are scheduled to be delivered over the next several weeks. The project is currently approximately a Quarter ahead of schedule for full transition of mining activities by the end of Q2-2017.

Caribou Underground Resource Conversion and Expansion Drill Program Commences

Trevali also announces commencement of its 2017 underground diamond drilling program. Boart Longyear Canada have been awarded the 14,400-metre contract for underground diamond drilling services. The program is a follow up to the 14,000-metre 2016 drill program that targeted inferred and indicated resources on both the North and East limbs of the deposit.

The 2017 program will continue this effort below the current workings on both the North Limb and East Limb, with a concerted emphasis on the down-plunge area of the North Limb that shows the greatest potential for addition of inferred resources (Figures 2 & 3). The goal for the 2017 program is to upgrade a significant portion of inferred resources (approximately 2-2.5 million tonnes) to the indicated category. A portion of the 2017 program is also slated to further delineate and upgrade indicated resources into the measured category. The proposed Caribou underground drilling for 2017 is shown in the longitudinal section views below (Figures 2 & 3).

In addition to the Caribou underground drill program, a surface drill campaign is currently underway to test near-mine targets.
