Howlett Research Corp. Publishes Research Report on Yale Resources Ltd.

Market Wire, April, 2008

Howlett Research Corp. ( www.howlett-research.com ), a boutique research firm led by Jeff Howlett, President, announced today that it has recently published a research report on Yale Resources Ltd. ("Yale") (TSX-V: YLL) (PINKSHEETS: YRLLF) (FRANKFURT: YAB) ( www.yaleresources.com ).

Over the past 1.5 years, Yale has assembled a portfolio of Mexican properties in world class mining districts. The large number of mineralized occurrences and small scale mining operations throughout their properties has dictated that a rigorous, systematic exploration program be followed. Over this time, literally thousands of samples have been collected and there have been several targets investigated by geophysics. This program has begun to bear fruit:

--  Drilling is now underway at two initial targets at Urique North,
--  Work at the past producer Verde Grande has resulted in a new geologic
    interpretation, a significantly greater strike, and potential for new
    processing methods (i.e., heap leach vs. traditional flotation),
--  The company continues at Urique South to prioritize the (now 7)
    targets for later drilling,
--  At the Carol property, sampling over wide areas in two skarn zones has
    yielded several high grade results -- further hand trenching indicates that
    copper oxides occur in each trench over 6 - 22 m widths.
