Trevali Expands Magistral Central, Fatima Zones at Santander Mine

Trevali Mining Corp. (TSX:TV,OTCQX:TREVF,FWB:4TI) reported that all 5 drill holes from its 2015 exploration program at its Santander Zinc Mine in Peru intersected significant lead-silver-zinc mineralization and remain open for expansion. Highlights include: 42.1 metres* of 8.3% Zn, 1.9% Pb & 3.5 oz/ton Ag at Fatima-Central and 14.8 metres* of 9% Zn, 0.5% Pb, 2.0 oz/ton Ag at Fatima.
As quoted in the press release:

FATIMA ZONES
Discovered in 2014, the Fatima North and South zones trend sub-perpendicular (approximately 80-85°) to the main Magistral Central deposit. Fatima North is currently better defined and has dimensions of approximately 60 metres (east-west), ranges from 5-to-15-metres wide and extends at least 150-metres down-dip where it remains open. Fatima South is the smaller sibling (from 2-to-3-metres wide) but is higher grade and appears to converge towards Fatima North at depth. For example, drillhole FA-118-15 was designed to test the down-dip extension of the Fatima zone where it was interpreted to intersect the main Magistral Central deposit and resulted in the intersection of a particularly broad zone of massive sulphide mineralization (Table 1 & Figure 2).
Analogous to the Rosa zone at Magistral North, the Fatima zones are interpreted to represent a later-stage overprinting phase of lead-silver rich replacement mineralization along a set of roughly east-west trending feeder structures/veins that trend towards the Company’s nearby Puajanca prospect. The results suggest that Fatima North and South may merge at depth to potentially form a single large mineralized area however the Company cautions that additional drilling is required to test this hypothesis (Figures 1 & 2).
Located in the footwall and subjacent to the existing underground development, the Fatima zones are readily accessible for incorporation into the current Santander mine plan. Initial mining from Fatima commenced in Q2 of this year with modest production from this new zone to date.
MAGISTRAL CENTRAL
These most recent drill hole intercepts from the down-dip extension of Magistral Central suggests that mineralization width and grade is increasing at depth with multiple replacement zones intersected in several of the drill holes (Table 1). Prior to this, the Magistral Central zone returned relatively modest Pb and Ag values however silver-bearing galena was intersected in drill holes SAN 205 and 207 with values of up to 5.8% Pb and 9.85 oz/ton Ag returned. These may represent the (offset) down-dip extension of the Fatima zones and/or the upper portions of an as yet undiscovered new “feeder” zone.
Drill holes SAN-206 and SAN-208 (assays pending) are interpreted to indicate that the Magistral Central and Magistral South zones may merge into a single zone at depth. The area sits above and is spatially associated with a very large, strong geophysical anomaly (Down-Hole Electromagnetic anomaly approximately 300-by-300 metre modelled conductive plate) that extends at least an additional 150-200 metres deeper than current drilling and remains open to the north, south, east and at depth.
Drilling from both surface and underground is ongoing.

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

“Bigger picture, we believe we have barely scratched the surface at Santander, which geologically is already one of the larger-end members of the Carbonate Replacement Deposit type. All of the currently known zones, including the former-producing Santander Pipe, remain open for expansion and we have multiple earlier-stage priority targets on our large property package that require future drill testing.”
