(PresseBox) - Silver Corp. (MAG: TSX / NYSE A) (?MAG? or the ?Company?) reports the discovery of the northeast (?NE?) oriented ?Venadas Vein? within the Minera Juanicipio Joint Venture Property (Fresnillo plc 56% / MAG 44%).


New Venadas Vein discovery is the first ever mineralized vein in the Fresnillo district oriented at a high angle (NE) to the historically mined northwest (?NW?) oriented veins.

Venadas intercepts lie at a very high-level in the vein zoning model, suggesting considerable depth potential.

Larger NE structures with intense surface alteration are known within the Juanicipio property and are now high priority exploration targets. None have ever been directly drilled.

The NE-oriented Venadas Vein was inferred from the alignment of fifteen previously unconnected intercepts (See Table 1, Figures 1 & 2) before being cut in an underground development working as a 1.1 metre (?m?) wide vein, reporting 116 grams per tonne (?g/t?) (3.4 ounces per ton (?opt?)) silver, 3.16 g/t gold.

Venadas is the first ever mineralized vein in the overall Fresnillo District oriented at a high angle to the historically mined NW oriented veins. Notably, other much larger NE structures with intense surface alteration are known farther afield within the Juanicipio property and are now priority exploration targets. None have ever been directly drilled.

?This is an entirely new and previously unrecognized vein trend that runs opposite to the expected NW-orientations shown by veins mined for nearly 500 years throughout the known parts of the Fresnillo District. The JV exploration team deserves great credit for puzzling it out? said Dr. Peter Megaw, MAG Silver?s Chief Exploration Officer. ?We think these may be very important controls on the overall mineralization system because the Valdeca

Possible Significances

The recognition of NE-oriented veins different from the well-known NW-orientated veins of the Fresnillo District opens many exploration possibilities within the Juanicipio claim and the district as a whole. Similar NE structures with very strong alteration are known elsewhere within the Juanicipio claim and have seen only reconnaissance mapping: All now become priority exploration targets.

Most Venadas Vein intercepts to date lie above 1,850 m elevation. This is the depth of the top of the Valdeca metres.

The Venadas Vein projects directly towards the overlap zone between the Valdeca

Two suspected similarly NE-oriented structures lie a few hundred metres on either side of the Venadas Vein and are also indicated by unconnected intercepts and extensive surface alteration. The structure to the southeast projects into a distinct vertical bulge in the Valdeca

Venadas Vein History

The Venadas Vein was originally intersected in 2011 in Hole 43P, which cut 4.15 m (drilling width) grading 491 g/t silver (14.3 opt) and 2.69 g/t gold Including 1.65 metres grading 965 g/t silver (28.1 opt) and 6.39 g/t gold (See Press Release of September 1, 2011). Several attempts were made to offset this intercept based on the premise that the vein was NW-oriented like all other known veins in the Fresnillo District.) grading 392 g/t (11.5 opt) silver, 5.56 g/t gold, with no Lead, Zinc or Copper at 1,905 m elevation. VEN-1 was completed about the same time the Conveyor Ramp exposed the Venadas Vein underground, where cross-cuts now follow it for roughly 20m in both directions. Channel sampling there shows a 1.1 m width, reporting 116 g/t (3.4 opt) silver, 3.16 g/t gold with no base metals.
