Approximately 3-years of underground development is currently in place: In detail, ramp and level rehabilitation and access to two of the first four production areas are approximately 90% and 75% complete respectively. The third and fourth production zones are 40 to 50% complete and continue to progress to schedule and plan. There are currently approximately 600,000 tonnes of mineralized material available for production.

Surface crusher installation is in progress to a newly designed radial stacking pad. Based on the Company's successful Santander commissioning, Trevali is currently planning to stockpile approximately 60-80,000 tonnes of UG material prior to commencing Q2-2015 Mill commissioning.

The main dewatering pumps are fully installed and site is currently dewatering at full 600 gallon-per-minute capacity. The Mine is currently dewatered to approximately 250-metres subsurface.

The UG Paste Backfill study is advancing and results are expected in early Q1-2015.

Geotechnical drilling has been completed in order to access long-term tailings management planning.
The Mill site has been contoured to improve surface water management.
Fire suppression system is refurbished and fully operational.

GEOLOGY

Exploration targeting and drill testing of potential extensions of both the East and North Mine Limbs has resulted in the intersection of significant intervals of massive sulphide mineralization ranging from 7 metres to plus-45 metres downhole thicknesses and remain open for extension. Assay results are pending and will be released upon receipt.
