 Trevali Mining Corporation (TSX:TV,OTCQX:TREVF,FWB:4TI) reported that due to recent positive development at the Rosa Zone in the Santander Mine in Peru, it has been developed on four sub-levels in preparation for mining.

As quoted in the press release:

Due to the highly-encouraging drilling results (see News Release TV-NR-13-23, October 8, 2013) and given its proximity to the main Magistral North underground ramp, the Rosa Zone has been developed on four sub-levels in preparation for mining. All drifts have encountered massive-sulphide base metal replacement mineralization (Figure 1). Based on underground drift cuts and drill hole intercepts, the dimensions of Rosa Zone is currently estimated to be approximately 70 metres in length (along strike), 3-to-15 metres in width and extends at least 100 metres from surface along plunge. The results suggest that there is a trend of increasing grades and thickness of mineralization with depth. It remains open for expansion and underground drilling targeting the deeper portion (below the 4510 level) of Rosa Zone is in progress.

Trevali Mining President and CEO, Dr. Mark Cruise, said:

The style, intensity, persistence and high silver-lead grades encountered in both drilling and underground development to date suggest that the Rosa Zone has the potential for significant expansion potential at depth. Given the characteristics of the overall Santander mineral system, similar high-grade structural-replacement zones may be anticipated to be present in the Magistral Central and South deposits.
