Barker Undertakes Diamond Indicator Sampling Program on its Tasse Diamond Project
Prince George, B.C., August 5, 2010 -- Barker Minerals Ltd. ("BML" on TSX/V) (the "Company") reports that a heavy mineral stream sediment program is underway on its Tasse Diamond project. The project is located 180 km south of Prince George and 84 km northeast of Williams Lake, in the Cariboo region of British Columbia. (Tasse Property Map) The project has excellent access and infrastructure nearby. (Excellent Access and Infrastucture)
A hill covering 15 sq km's is believed to be a part of a volcanic vent complex. Vesicular breccia associated with the vent (hill) contains abundant large clasts and xenoliths of coarse granular olivine, pyroxene and garnet, and is considered to be mantle peridotite. The hill is believed to be associated with a lamproite diatreme and the xenoliths of mantle rock in the breccia could possibly contain diamonds. It is located off the western edge of the North American Craton in a Mobile Terrane which is associated with deep faulting. (Tasse Diatreme 1, Tasse Diatreme 2)
Indicator Mineral Study
Stream sediment samples will be collected from the drainages near a number of bedrock pipes and the nearby Diatreme complex. The samples will be sieved down and analyzed for potential diamond indicator grains which would show up after the heavy mineral separation phase. A number of grains from each sample will then be chosen for identification and follow up microprobe studies to determine the geochemistry. Caustic fusion will also be used to determine if micro diamonds are present in the concentrates. (2010 Sediment Sample Locations)
Most of the current samples collected for analysis have heavy mineral concentrates which are very similar in nature and include a variety of different color garnets and associated heavy minerals. (Examples of selected grains collected in the current program -- Grains 01, Grains 02, Grains 03, Grains 04)
On April 20, 2009 Barker announced that eclogitic garnets were identified on the Tasse project which are formed at similar depths in the mantle as diamonds. The identification of eclogitic garnets indicates that the Tasse mantle rock has been sampled deep enough in the mantle to tap the diamond stability field, and thus could contain diamonds.

Airborne Magnetic Targets
On November 27, 2009 Barker announced that the Geological Survey of Canada completed an Electromagnetic (EM) and Magnetic Airborne Survey (The Cariboo Lake EM/Mag Survey) over the Tasse Project area. (Nov 27, 2009 NR)
One of the most prominent magnetic features over the survey area is a cluster of fifteen moderate to high strength circular anomalies which appear to be a cluster of mantle pipes. The heavy mineral concentrate samples will be collected from areas in and around this cluster of anomalies in order to identify any areas for follow up to determine if economic diamond potential exists on the property.
