Alta Vvista Ventures Ltd. Announces that Geophysics Confirms Depth Potential for Drill Targets at Urique North by 24hgold

	Thursday, March 27, 2008 YALE ANNOUNCES THAT GEOPHYSICS CONFIRMS DEPTH POTENTIAL FOR DRILL TARGETS AT URIQUE NORTH
	News Release #08-12 Yale Resources Ltd. (TSX-V - YLL and Frankfurt - YAB) is pleased to announce that a recently completed 13.35 km IP geophysical survey within the Cerro Colorado and San Pedro targets of the Urique Project indicates that the mineralization and alteration identified on surface may extend to depths greater than 100 metres. The Cerro Colorado and San Pedro target areas are now ready for drilling. The geophysics program included 5.4 line km within the Cerro Colorado target and 4.75 line km within the San Pedro target area. In each area geophysical anomalies coincide with mineralized structures and veins and in many cases even the dip of the anomalies are similar with those measured on surface. The Urique Project is 290 square kilometres in size. It is located within the prolific Sierra Madre gold belt and adjoins Goldcorp's El Sauzal gold mine to the south and Kimber Resources' Monterde Property to the north. Yale has the right to earn a 75% interest in the Urique Project from EXMIN Resources Inc. (EXM - TSX.V). Cerro Colorado: The Cerro Colorado target consists of a 2 to 9 metre wide structurally controlled breccia more then 2.5 km in length with two sets of historic workings (El Vergel and Mina Guadalupe) that occur in river drainages located approximately 1.5 km apart. Grades of 2.23 g/t gold and 150.0 g/t silver over 3.0 m from the El Vergel zone and 5.46 g/t gold and 36.0 g/t silver over 9.1 m from the Mina Guadalupe zone have been encountered (see news release dated February 15, 2007). Figures showing the geophysical profiles from the Cerro Colorado target area are available on the Company's website at: http://www.yaleresources.com/s/UriqueGeophysics.asp San Pedro: The San Pedro target area surrounds the historic Sangre de Cristo gold-silver mine (owned by a third party) where field work has identified several small mines and prospects developed on quartz veins. Assays from these showings range from 6.6 to 35.0 g/t gold and 61.0 to 401.0 g/t silver over 0.3 to 1.1 metre vein widths (see news release dated May 17, 2006). In addition three principal sets of gold-silver veins have been discovered with several of the narrow vein systems having yielded high-grade precious metals assays with highlights of 137.5 g/t gold and 133.0 g/t silver over 0.25 metres. Sampling of widespread alteration coincident with the intersections of north-south and northeast vein sets suggests that there may be potential for bulk mineable mineralization in the target area as trenching has uncovered mineralization grading 0.33 g/t gold and 7.6 g/t silver over 21.65 metres.
