São Martinho SMD-009 Hits 56.4m of Gold at 2.34 g/t from
Surface
W Resources Plc (AIM:WRES), the tungsten, copper and gold
mining, production, exploration and development company with assets
in Spain and Portugal, is pleased to announce some exceptional
results at its São Martinho Gold project in Portugal.
SMD-009 results have confirmed a very thick gold intersection of
56.4m at 2.34 grams per tonne (g/t) from the very shallow depth of
2.6m. The thickness of the intersection bodes well for an increase
in the size of the ore deposit and the potential to mine ore at low
cost given the shallow nature of the zone.
New results from Holes 5-9 and an upgrade from further sampling
of Hole 4 have yielded very positive results:
-- SMD-009 was the highlight with a wide zone of 55.6m at
2.34g/t from 2.5m with an additional deeper zone of 3.55m at
1.69g/t Au from 194.95m identified
-- Infill sampling of hole SMD-004 significantly improved the
results with thicker intersections
-- Hole SMD-007 reported two gold bearing zones with a shallow
zone at 18-20m and a deeper zone at 104m
In addition to these first assay results visual gold has been
picked up in holes SMD-010 and SMD-011.
Michael Masterman, Chairman of W Resources commented: "São
Martinho SMD-009 is a very positive result with a very thick
intersection of over 55m of gold at 2.34g/t. The result provides a
solid base to drive extension drilling with the potential for
materially larger resource. We are very pleased with the results
from this drilling programme."
Further results from this diamond core programme at São Martinho
will be progressively released as the assay results come
through.

About CAA / Portalegre
On 23 March 2012, W Resources' 100% owned subsidiary, Iberian
Resources Portugal, was awarded a licence for the exploration of
the "Crato-Assumar-Arronches area", adjacent to the original São
Martinho gold prospect area. Both areas are located near the town
of Portalegre (Northern Alentejo) and around 200km East of Lisbon.
The CAA area covers an area of 188.05km(2) and the São Martinho
area has an area of 101.7km(2). The expanded licence is valid until
September 2018.
Technical information in this report and on the W website has
been prepared in accordance with the JORC Code or defined by
National Instrument 43-101 and approved for inclusion by Mr José
Mario Castelo Branco, EuroGeol, who is a "qualified person" in
respect of the AIM Rules for Companies with over 32 years'
experience in the Exploration and Mining Geology industry. Mr
Castelo Branco holds a B.Sc. in Geology from the University of
Porto in Portugal. He is also a member of the Portuguese
