Sierra Target Discovery
Seventeen Samples Average 4.8% Cu, 101 g/t Ag and 4.4 g/t Au
VANCOUVER, Oct. 18, 2013 /CNW/ - The Company reports that its field crews have made a discovery (the "Sierra Target") on its 100% owned El Cobre property Sonora, Mexico. The new Sierra Target consists of hydrothermal breccias, with diatreme characteristics and occurs in Miocene volcanic units at an elevation of some 700 meters above, and further to the West of Westminster's Montoso porphyry system currently being explored under option by Capstone Mining Corp. Seventeen hand samples were collected and assayed using various ore grade methods which determined an average grade of 4.8% copper, 101 g/t silver (400 g/t cutoff) and 4.4 g/t gold. The slabbed rock samples contained no obvious sulphides but were rich in barium and iron (hematite ranging from about 3% to 12% Fe). The accompanying table shows the highest contents of silver assayed 1,479 g/t (47.4 oz/t), gold 21.79 g/t (0.69 oz/t) and copper 10.2% with these values reported from 3 different samples. These breccias also appear to be rich in bismuth, mercury and tungsten and represent a new deposit type for the Company's Sonora properties.

The steeply dipping breccias appear to be in a fluidized zone where crackle, jigsaw and rock flour cemented matrix textures are present. The variable nature of the clasts is very evident as some are green colored with malachite or chrysocolla while other samples without significant copper oxides also contain high percentage grades of copper. Two separate exposures about 150 meters apart were likely explored in the 1950s by hand mining for the high-grade silver in brecciated material.
The company plans to further map and systematically sample the target area. The previously flown VTEM and MAGNETIC Surveys have identified conductive and high-low magnetic patterns which may indicate hydrothermal activity in the area associated with the breccia hosted mineralization.
Preparation and Analyses
Representative hand samples collected from the Sierra target breccia were shipped to Canada where they were sawn and slabbed. The offcut rock portions were numbered and sent for sample preparation at Acme Laboratories Vancouver. The numbered slabs were kept for reference and mineralogical investigation. Acme Labs used the prepared pulps to determine elemental and metal contents by assay and check analysis including methods 1F06, G814, G613, 7TX, 7TD, G6Gr, 4AB1, 2X and G1E.
This assay and geochemical characterization of the high grade Sierra breccias mineralization now has provided the Company with the best assay methodology to use during its systematic sampling of the Sierra target area.

ON BEHALF OF THE BOARD OF DIRECTORS
WESTMINSTER RESOURCES LTD.
Managed by an experienced exploration team the Company is focused on exploring and developing prospects on a land package of approximately 51,767 hectares of contiguous mineral concessions in Sonora, Mexico. These concessions constitute a mineral district scale property serviced by roads, power and water. Approximately 10,109 hectares comprise the Cumbral-San Bartolo option project with Capstone Mining Corp. Capstone has secured a 49% interest in the project having spent $3.3 million to date; Capstone Mining Corp. has the exclusive right under a formal Joint Venture Agreement to earn a further 11% interest by expending an additional $3 million by December 31, 2014 and can earn a further 10% interest by expending an additional $3 million before December 31, 2015, bringing their total expenditures to $9.3 million to earn a 70% interest.
