Magnum Discovers Significant Radon Anomaly at 35-75 Uranium Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 26, 2007) - Magnum Uranium Corp. ("Magnum" or the "Company") (TSX VENTURE:MM) is pleased to announce the discovery of a large and statistically significant radon anomaly at its 35-75 Uranium Property (the "35-75 Property") in Converse County, Wyoming. The property is located within the Powder River Basin, immediately adjacent to Cameco Corporation's Smith Ranch uranium operation (the "Smith Ranch"), the largest producing ISL uranium deposit in the United States hosting reported proven and probable uranium resources of 13.3 million pounds. The same Tertiary sandstone horizons which host the Smith Ranch deposits are thought to be the host of the mineralization at the 35-75 Property.

Magnum recently completed an alpha track radon survey of the 35-75 Property that discovered an anomaly which is approximately 2,500-feet long (760 m) in a north-south direction, 2,000-feet wide (610 m) in an east-west direction and covers an area of 87 acres. The anomaly has a peak value which is at least 30 times background readings. The anomaly significantly expands a north-south trending zone of mineralization, nearly 1-mile-long, located immediately to the south of the radon anomaly that was detected by historic drilling conducted on the property by Cordero Mining Co. ("Cordero") and Teton Exploration, Inc. ("Teton"). Magnum owns a database consisting of maps detailing at least 265 historic drill-hole locations and 116 historic summary drill-hole logs completed by Teton and Cordero around 1970. Additional deposits are speculated to be present based on close-spaced drill patterns on other parts of the property.

Magnum's alpha track radon survey was conducted during October 2007 by Stratamodel Inc. covering one square mile of Magnum's property position. The objective of the survey was to identify radon anomalies emanating from subsurface uranium mineralization. A total of 147 detectors where used as a primary measure of soil radon including QA/QC of five duplicates to quantify sampling error, three detectors to quantify analytical error, and three detectors used as blanks. The survey grid consisted of 136 nodes with an average spacing of 100 m in the northwest-southeast direction and 200 meters in the northeast-southwest direction. The grid was oriented parallel to the main trend of mineralization blocked out by historic drilling. Sample points were randomly selected within 100 by 200 meter grid cells. Grid cell dimensions were selected by dividing the dimensions of the known extent of mineralization by three. Field locations were determined by DGPS control.

Magnum plans to conduct an aggressive drilling program in the spring of 2008 to test the anomaly down-dip, and test for the presence of multiple stacked roll deposits in the Eocene Wasatch and underlying Paleocene Fort Union Formations.
