Trevali Mining Is On Track and On Schedule for Caribou Mine Restart

Trevali Mining Corporation (TSX:TV,OTCQX:TREVF,LMA:TV,FWB:4TI) reported that surface and underground development programs at Caribou mine and mill complex New Brunswick, Canada, remain on schedule and on budget for start-up commissioning in the first half of 2015.

As quoted in the press release:

SURFACE WORKS

• The fully refurbished Main Mine Office annex is now staffed by Trevali’s engineering and management team.
• Site communications are being significantly enhanced by installation of a new fibre-optic cable to the minesite, which is currently underway and scheduled to be commissioned later this year.
• The Mine Dry Facility and Change House, necessary for Underground (“UG”) activities, has been refurbished.
• Site power repairs are predominantly complete.
• Improved site water management requirements have been identified and tendering is underway.

MILL

• The new 3,000-tonne-per-day Semi-Autogenous-Grinding (SAG) Mill and componentry (Figure 2) is onsite. Removal of the old SAG mill is currently underway with installation of the new SAG scheduled to be completed by early 2015.
• Key mill component spare part purchasing continues and is progressing well. Miscellaneous replacement and spare pumps, and additional equipment have been acquired from the recently closed Brunswick 12 mine complex and is onsite.
• Water supply to the mill has now been fully restored and clean-up activities are ongoing.
• Detailed mechanical, civil and electrical design for the copper recovery circuit is in progress.

UNDERGROUND

• Approximately 3-years of underground development is currently in place.
• Underground refurbishment and development by Trevali’s contractors Alex Macintyre & Associates Ltd. continues to progress well and remains on schedule (Figure 3).
• Underground mining fleet delivery is underway.
• Underground ventilation fans are all operating well and underground heating units are scheduled to be operating over next 3-4 weeks.
• Dewatering is progressing well with electrical substations now installed on Level 2 and the larger main pumps in the process of being installed.
• The Paste Backfill Study continues to advance, which contingent on positive results has the potential to significantly increase the life-of-mine, in addition to decreasing mine dilution (boosts head-grade) and lower operating costs.
