First Hole at São Martinho Intersects Gold on 6 Levels
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 initial results of
the first hole from the 1,500 metre diamond core drilling campaign
that commenced in mid-September at the São Martinho Gold Deposit in
Portugal.
A total of nine of holes have been drilled so far and the first
assay results concluded, from the first hole SMD-04, that this
intersected significant gold mineralisation in 6 levels including
2m at 4.2g/t and 2m at 7.6g/t.
Highlights from Hole SMD-04 include:
-- 2.40m grading 4.2 g/t Au from 32.90m
-- 2.00m grading 1.1 g/t Au from 90.00m
-- 7.00m grading 1.7 g/t Au from 95.70m
-- 8.00m grading 1.8 g/t Au from 157.00m* (including 1.00m grading 9.6 g/t Au from 157.00m);
-- 3.00m grading 3.0 g/t Au from 177.00m (including 1.00m grading 8.0 g/t Au from 177.00m);
-- 2.00m grading 7.6 g/t Au from 187.60m (including 1.00m grading 14.2 g/t Au from 187.6m).
* This zone extends over 12m at least, probably down to 169.00m,
however the additional infill sampling results are not yet
available.
Further information on Hole SMD-04 is included below.
This hole was planned to confirm the upper mineralised section
from a previous high-grade intercept drilled in the early nineties
by Portuglobal, and to investigate the deeper parts of the gold
system which were not drilled previously. Both objectives have been
fully achieved. The shallow section although narrower correlates
well with that in hole POR-96-2 and a new high-grade deeper zone
that may potentially increase the resource basis with additional
drilling.
In addition to these first assay results, visual gold has been
picked up in holes SMD-10 and SMD-11.
These assay results will form part of the update to upgrade the
JORC compliant mineral resource estimate, completed by Golder
Associates in June 2016, which currently reports a total of 3Mt at
1.04g/t gold, which equates to 111,987oz in contained gold.
Michael Masterman, Chairman of W Resources commented: "The
results from the first hole at São Martinho are a great start with
good grades at multiple levels from the relatively shallow 4.2 g/t
Au at a downhole depth of around 33m to the deeper results. The
pick-up of visual gold in subsequent holes 10 and 11 together with
these first results bodes well for a very successful program. Our
objective is to step out and significantly expand the size of the
JORC gold resource which currently sits at over 110,000 oz."
Further results from this diamond core program at São Martinho
will be progressively released to the market as the assay results
come through.
The information contained within this announcement is considered
to be inside information prior to its release.

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.
