Standard Uranium Inc. Completes Claim Staking Program in the Kaycee Uranium District, Powder River Basin, Wyoming

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 25, 2005) - Standard Uranium Inc. (the "Company") (TSX VENTURE:URN) is pleased to announce that it has staked 129 claims covering 2,280 acres on the western margin of Wyoming's Powder River Basin. This recent acquisition includes minor historic uranium resources in two main areas within the Kaycee Uranium District: the Geronimo block to the south and the Red Cloud/ Tall Bull claim group to the north. A map of the area can be found on the Company website at:

The Kaycee District encompasses a 40-mile long series of roll front deposits hosted by sandstone units within the Eocene-aged Fort Union and Wasatch Formations. These formations host major deposits further to the east and to the south within the Powder River Basin. Although the Kaycee area itself has no historic uranium production it lies on the western edge of the Powder River Basin, a broad basin known for both historic and current uranium production via in-situ leach (ISL). According to a 1982 report by Fruchey and Eichorn, the Kaycee properties acquired by the Company contain open-ended resources in several roll front systems of 652,805 lbs from material grading 0.085% U3O8. These mineralized bodies vary in depth from less than 250 feet to as much as 475 feet. A 1980 study by Hunkin Engineers Inc., including hydrology testing and bench-scale leach testing, concluded the deposits were amenable to ISL recovery. The Company expects that additional drilling could add significantly to these historical resources. The nature and extent of future work in the region will be determined in due course as additional information is obtained for the recently acquired Pumpkin Buttes and Turnercrest properties to the east (Company news release 5/5/05).

Corporate Update

Mr. A. Murray Sinclair, a director of the Company, has resigned from the board in order, however he will remain available for technical assistance on an informal basis. The Company is also pleased to announce the addition of William D. Collins as Chief Geologist, John R. Hardin as Landman and the promotion of the Company's consulting geologist Frank Ludeman, to Manager of Acquisitions.

Mr. Collins started work in the uranium industry in 1955 for Hidden Splendor Mining, Atlas Minerals' predecessor, and worked primarily in Utah, Colorado, and New Mexico in and around uranium mines. In 1972, Mr. Collins left Atlas to join Wyoming Minerals Corp. (Westinghouse) where he progressed from Senior Scientist to Regional Manager in Wyoming and Manager of Exploration at their headquarters in Denver, CO. From there, he worked in most of the uranium producing districts in the U.S., with foreign experience in countries such as Canada and Australia.

Mr. Ludeman's uranium career started in 1960 at Kerr-McGee's underground mines in the Ambrosia Lake District of New Mexico. In 1967 he was named Chief Geologist of the Wyoming Uranium Operations Group with primary responsibility for development of the South Powder River Basin deposits and finally Mine Superintendent of the Shirley Basin operations. He joined Wyoming Minerals Corp. in 1975 as Manager of ISL development and operations with mines in Texas, Utah and Wyoming.

John R. Hardin, owner of Hardin & Associates, Castle Rock, CO, has over 30 years of land experience in the natural resources industry as Manager of Domestic Lands for Anaconda Minerals and Arco Coal Co. with a primary focus on acquisition of hard rock minerals, lease minerals, coal resources, uranium, phosphate and oil shale. For the past ten years he has provided consulting land services and property management for various mining projects.
