Yale Continues to Encounter Encouraging Results at Urique

News Release #12-06

Yale Resources Ltd. (TSX-V -- YLL, OTCBB -- YRLLF, and FSE -- YAB) is pleased to report additional gold and silver results from its ongoing comprehensive work program at the 290 square kilometre Urique Project, located in Chihuahua State, Mexico, immediately north of Goldcorp's El Sauzal gold mine and immediately south of Kimber Resources' Monterde Property. Work at Urique is being performed on behalf of optionee Mammoth Resources Ltd.

A majority of the work in the southern portion of the Urique Project has been concentrated on the approximately four kilometre by four kilometre area immediately surrounding the town of Urique. The most important target identified, to date, is the El Rosario Target, which is defined by an approximately 175 by 450 metre silica alteration zone on surface with multiple widely spaced workings that tested the system over a vertical extent of approximately 200 metres. Previous sampling by Yale encountered bonanza grades of silver (+1,000 g/t) over narrow widths (see news releases dated Feb. 6, 2008) whereas recent sampling has been successful in identifying wider widths of mineralization such as the highlights below:

1.5 metre chip sample grading 4.77 g/t gold and 49.5 g/t silver;
4.2 metre chip sample grading 1.21 g/t gold and 12.6 g/t silver; and
1.4 metre chip sample grading 2.03 g/t gold and 14.4 g/t silver.

The El Rosario Target area is centred on the El Rosario working, which is made up of at least 600 metres of underground development that tested five veins -- the longest of which was developed along at least 300 metres of strike length.

New mapping at El Rosario has re-interpreted a key geological unit that hosts the veining (and historic mining) at the El Rosario level to be a volcano-sedimentary unit that is much more extensive than previously thought. The orientation and size of this altered volcano-sedimentary unit may have significant implications on the controls on the emplacement of the high grade gold-silver mineralization and, as a result, on the potential to identify either feeder zones and or larger targets at depth.

Ongoing surface mapping and sampling continue to define the mineralization and alteration on surface as infill sampling has been successful in identifying additional zones of interest. A summary of the widespread sampling (defined by the nearest working) is provided below -- to see a map of the El Rosario Target Area locating samples mentioned in this news release please click the following link: http://www.yaleresources.com/s/Urique.asp

About Yale Resources:

Yale Resources utilizes the project generator business model to maximize its exposure to discovery while minimizing shareholder risk. Yale currently has eight projects in its portfolio of which four are optioned out with commitments totalling approximately $1.0 M in expenditures during the next 12 months.

Ian Foreman, P.Geo., is Yale's Qualified Person, according to National Instrument 43-101, for the Urique property and is responsible for any technical data mentioned in this news release.

Samples from Urique were prepared and analyzed by IPL Inspectorate in their facilities in Mexico and Vancouver, respectively. Samples generally consisted of 1-3 kg of material. Gold analyses were performed by 30 gram fire assay with an AA finish. Silver, copper, lead and zinc were analyzed as part of a multi-element ICP package using an aqua regia digestion. Over limit samples with greater than 1% Cu, Pb and Zn were re-analyzed using ore grade detection limits.
