EXP Experion Holdings Ltd

Canadian Shield Resources Ltd. (TSX VENTURE: EXP) ("Canadian Shield" or the "Company") has contracted SRK Consulting (U.S.) to prepare a Technical Report, consistent with the standards of NI 43-101 on the Company's Estrella gold & silver property located in the Central Peru polymetallic belt. The property contains 1,200 hectares and is located 130 km south of Huancayo in the Department of Juancavalica. Canadian Shield holds a 100% interest in the property.

The Estrella property contains a volcanic-hosted epithermal gold-silver system with associated base-metal mineralization hosted within a north-south trending graben. The property has a total of 615 surface rock samples and 33 drill holes totalling 5,800 meters of drilling. Gold assays from outcrops and drill holes range from 0.2 - 54.0 g/t and average 0.44 g/t gold. Silver mineralization assays range from 15.0 - 1,400 g/t and average 21.15 g/t silver. Three different styles of mineralization are present within a 1,200 meter north-south by 200 meter east-west zone, which remains open for expansion. The largest area of mineralization occurs as a north-south trending, west dipping, irregular, stratabound zone measuring 50 - 150 meters in thickness. This stratabound zone contains variable grade gold and silver mineralization with disseminated and vein hosted pyrite, tetrahedrite, galena and sphalerite. The zone has been intersected along strike for 600 meters, and remains open to the north and south. It also remains open up and down-dip. The second type of mineralization consists of a flat-lying tabular zone 10 - 25 meters thick that is located at or near surface. This flat lying zone occurs above the stratabound zone. It measures approximately 200 meters east-west and 130 meters north-south. The third type of gold and silver mineralization cross-cuts both the stratabound zone and the flat-lying mineralization. It occurs in north and northeast trending, sub-vertical fault zones, which outcrop at surface. It has also been intersected in drill holes, which extend north of the stratabound zone for 600 meters. The sub-vertical zone locally contains some of the highest grade mineralization on the property, including drill intersections of up to 11 meters @ 311.2 g/t silver and 0.59 g/t gold (RC-E10 from 43 - 54 m). It also remains open along trend to the north and south and at depth.
