<B><P ALIGN="JUSTIFY">Las Vegas, Nevada, May 13, 2004 - Aberdene Mines Limited</B> (OTCBB: ABRM) is pleased to announce that it has entered into a letter of intent with Consolidated Global Minerals Ltd. (&quot;Global&quot;) regarding granting Aberdene an option to acquire a 100% interest in Global's interest (subject to a possible 5% NSR) in the Slide Mine and Horsefal projects.  The signing of a formal option agreement is subject to completion by Aberdene of satisfactory due diligence in respect of the projects.  The exercise terms of the option would include: Aberdene paying to Global $100,000 cash on the first anniversary date of the option agreement; issuing an aggregate 300,000 shares of common stock to Global prior to the first anniversary date; and incurring expenditures of at least an aggregate $1,500,000 over a period of two years.</P>

<P ALIGN="JUSTIFY">The Slide Mine and Horsefal projects are located approximately 8 miles west of the city of Boulder, Colorado.  The district is reported to have produced 412,000 ounces of gold, and 5 million ounces of silver from 1872 until 1959.  The Slide-Horsefal projects include several past producing mines with known historical production from previously producing gold and silver veins, known as the Klondike, Slide, Prussian, Twin, Iowa and Horsefal.  The gold deposits occur in telluride and pyrite veins that occupy fissures, most of which strike northeast and dip to the northwest.  The veins contain primarily high-grade gold/silver hosted in a glassy quartz matrix.  The veins range in size from less than a foot to over 5 feet in places.  Where two veins intersect the veins &quot;blow out&quot; at the intersection resulting in very wide and very rich mineralization.  The Slide vein has been known to attain widths of up to 50 feet and grades as high as 60 ounces Au/ton in one instance under these circumstances.  All the claims have been consolidated under controlled ownership; therefore, making it possible to mine multiple veins to benefit from economies of scale - an opportunity that has not been historically available.  At one time this was the largest producer in the district, and the largest employer in Boulder County.</P>

<P ALIGN="JUSTIFY">Upon completion of satisfactory due diligence, it would be Aberdene's intention to focus on re-opening the Corning Tunnel (Slide Mine) and Horsefal Shaft, confirm the historical resource estimates, and continue exploration on the developed veins, as well as explore all other known but undeveloped veins.  It is Aberdene's intention to put the Slide and Horsefal projects into production utilizing the facilities of the on-site, permitted, and fully licensed mill.</P>
