Westminster Resources Ltd. (TSX VENTURE: WMR) -
The Company is pleased to report additional analytical results
for core hole MWN 09-05 drilled at the Yori porphyry target. This
hole encountered drill problems but when abandoned had ended in
sulphide mineralization with the final 0.35 meters initially
reported (#WMR 09-11) as grading 0.76% copper and "over limit"
silver (greater than 10g/t). Check "over limit" assaying by ACME
Labs has now determined that the final interval grades 720 gm/mt
silver (23.15 ounces per mt) using fire assay for Ag by gravimetric
methods. This result further supports the interpretation that
drilling completed to date has intersected the outer halo portion
of a precious metal bearing copper porphyry system (#WMR 09-09 and
11). The initial drilling tested near surface an 800 meter portion
of the 3,500 meter long IP geophysical anomaly identified
earlier.
The nearby La Kala porphyry target has been identified by two
impressive topographic mineralized skarn features. The North La
Kala skarn has an outcrop strike length of 1.5 km and 2.5 km
further south, the South La Kala skarn is exposed. Rock chip and
hand specimen sampling has been limited to two small hand "pick and
shovel" Mexican prospector workings at these skarns and the
Company's initial results are presented as Table 1.

The La Kala skarns exhibit typical gold-copper bearing massive
skarn mineralization consisting of variable mixtures of garnet,
magnetite (see "MAG N" in Table 1), epidote (see "Epi-Qtz" in Table
1), chlorite, quartz, and tremolite. Massive sulphide veins, and
seams on fractures crosscut the skarn mineralogy in leached
outcrops. These are now classic boxwork textured limonites after a
variety of primary sulphides and range in colour from black to
brown to "bulls blood" red iron (see "LIM" in Table 1). The South
La Kala skarn app ears to be especially enriched in bismuth and
tellurium with an epidote and quartz-rich skarn sample containing
little suphides assaying 320 ppm Tellurium and over 2000 ppm
Bismuth (see sample "Epi-Qtz" in Table 1).
In Table One, analytical results for the weathered limonite
samples (LIM) show an almost total leaching of S% with strong
depletion of Cu considering the high Fe% values, rich silver
contents (about 1 opt to 9.4 opt) and gold ranging to 0.45opt.
These limonite vein samples are cross-cutting features but the
skarn horizons in themselves show gold enrichment. This is shown by
results from massive magnetite (see "MAGN" in Table 1) in a skarn
layer at 51 to 59% Fe enriched in gold (110 to 180 ppb) and the
epidote+quartz sample from a skarn horizon reporting 1.6 g/t gold
(Table 1, Epi-Qtz).
The high gold and silver grades reported from assays confirm
that the skarns are gold and silver-rich and are interpreted as
part of the peripheral mineralized halos of the La Kala precious
metal-copper porphyry system.
At the La Kala porphyry system, first-time mapping, geophysical
surveying and drilling are planned as gold-silver-copper skarns
such as those identified at the La Kala target may be economically
significant in their own right.
Planning for is Phase Two exploration at the Fafy-Yori and La
Kala targets at the Navojoa Project is underway with expected
mobilization in November.
Samples were analyzed for the Company by the Acme Analytical Lab
(an accredited analytical facility) located in Vancouver B.C. The
"over limit" silver result initially reported for the Yori MWN
09-05 core sulphides was subsequently analyzed by Acme method G613
Fire Assay Ag with gravimetric finish with a sample of 30g. Gold
results for the La Kala limonite and magnetite-rich samples ("LIM"
and "MAGN" in Table 1 ) were determined by Acme method G6 Fire
Assay fusion ICP-ES with a sample of 30g. All other elements were
analyzed by Acme method 7AX ICP-ES/ICP-MS.
