VANCOUVER, May 3 /CNW/ - Westminster Resources Ltd. ("Westminster" or "the Company") is pleased to announce the discovery of a significant new silver prospect now known as "San Bartolo" at the El Cobre property in Sonora, Mexico. The new discovery, made during the continuing prospecting program underway at the 17,000 hectare property, is located approximately 13 kilometers south east of the Company's Anita Copper Mine project. Initial rock sample results obtained by Westminster staff from samples collected at historic workings and prospecting over a strike length of one kilometer at San Bartolo returned numerous assays exceeding 100 grams/tonne silver (the upper limit for detection by the assay technique utilized).
During the period November to March the Company established a follow-up survey grid centered over the old artisanal pits and two shafts, for which no historical records exist. The San Bartolo survey grid consists of 1.5 kilometer long east-west cross lines turned off at 100 to 250 meter intervals from a 2.0 kilometer long north-south base line. At a sample spacing of 25 meters, a total of 801 soil samples were collected, and geochemical analysis has outlined a series of 5 sub-parallel anomalous zones extending the length of the grid, and beyond. Silver content in the soil anomalies for 64 samples ranges from 1000 ppb (1 g/t) to 5200 ppb (5.2 g/t), for 144 samples ranges from 500 ppb (0.5 g/t) to 1000 ppb (1 g/t) and for 191 samples ranges from 300 ppb to 500 ppb. Significant silver content in the anomalous soil zones occurs over widths that "pinch and swell" from 100 to 500 meters along the strike of the 5 trends.

Geological mapping of the San Bartolo target suggests the area is underlain by structurally-controlled quartz carbonate vein systems that are related to granitic dykes intruding an older altered diorite host unit. Ground geophysical surveys will commence immediately over the grid to assist the Company in prioritizing drill targets to test the silver anomalies in the next exploration phase planned.
In addition regional prospecting, several kilometers north of San Bartolo by the Company has discovered an extensive north striking trend of magnetite-sericite altered granite with associated oxide copper mineralization on fractures in subcrop. This discovery, named Cumbral, has a strike length of 2 kilometers and has scattered copper and magnetite float in strongly iron oxide coloured soils over widths up to 500 meters ending in a bleached quartz sericite altered zone with an historic mining pit, presumed to be precious metal related. Results from prospecting rock sampling are pending.
The Company has recently completed a regional stream sediment silt sampling and regional prospecting and mapping program over the complete El Cobre Property. Samples have been shipped for preparation and analyses.
"Preliminary interpretation of the Company's geological work at the Anita Copper Mine, San Bartolo and the new Cumbral copper -sericite- magnetite zone is continuing to reinforce our interpretation that the El Cobre Property has potential to host precious metal-copper porphyry systems," said Glen Indra , President of Westminster Resources Ltd.
All soil samples and rock samples were collected from the company secure storage facility in Obregon by Sonora Sample Preparation (SSP) Laboratory where they delivered them for sample preparation to their facility in Hermosilo. Sample pulps were sent by SSP to ACME Laboratories in Vancouver B.C.for geochemical analyses (method code ICP-MS 1 F). A duplicate set of San Bartolo soil grid samples has been sent to Activation Lab, Ancaster, ONT for Soil Gas Hydrocarbon (SGH) determinations, results pending.
The foregoing disclosure has been reviewed and verified by director Glen C. Macdonald, P.Geo., a qualified person for the purpose of National Instrument 43-101, Standard of Disclosure for Mineral Projects.
