ALERT: Gold Discovery Breakthrough With State-of-the-Art NITON XRF Testing at Gold King Mine Affirms Colorado Goldfields' Drilling Program

LAKEWOOD, CO--(Marketwire - November 11, 2008) - Colorado Goldfields Inc. (OTCBB: CGFIA) announces the results of NITON XRF analyses of select interval core samples from the Company's Gold King Mine property. The results of the NITON XRF analysis confirm that mineralization from Gold King B Vein contains gold grades ranging from .28 - 3.39 oz/ton, and silver grades of 1.46 - 30.97 oz/ton.

As part of the 2008 drill program, the Company completed 3,459' (1,054m) of core drilling in three drill holes. These particular diamond drill holes were positioned to test for NE-SW trending veins continuing from the property's Gold King-Davis vein system. As anticipated, these drill holes successfully intercepted multiple parallel veins throughout the length of the drilling. While several veins are interpreted as being continuous mineralized structures with potential, the 'B' Vein Zone demonstrated significant mineralization with an estimated true width of 12-13 feet and continuity.

"The 'B' Vein Zone was encountered in hole CG08-01 at a depth of 635 feet, expressing two strong quartz sulfide veins that are approximately 30 feet apart. Step-out holes to the northeast and to the southwest intercepted the 'B' Vein at 615 ft. and 680 ft., respectively. All three intercepts indicated that this is a strong, well-mineralized, and continuous structure, and as we anticipated and now demonstrated via the NITON XRF Analyzer, we have indeed established the presence of gold and silver in the Gold King Mine Extension -- that's very exciting," said Project Geologist Jonathan Moore.

While awaiting the completion of the entirety of assay results, being provided by Skyline Laboratories in Tucson, Arizona, Company management requested XRF analysis in order to obtain early indicative analyses of precious metal content. Management chose the Thermo Scientific NITON® XL3t handheld Analyzer because of its superior capabilities. While attending the testing at the Company's location in Silverton, Colorado, Stephen Guyer, the Company's Chief Financial Officer, declared, "We are most gratified to confirm there is gold in the Gold King property."

"The use of handheld XRF units, such as the NITON XL3t Analyzer within the mining industry has been demonstrated worldwide as a statistically reliable technology for field geologists and other technical personnel to acquire accurate results, instantly and efficiently. Personally observing the NITON XL3t Analyzer doing its job was inspiring and will greatly accelerate our ability to create measureable and confirmable results," said Guyer.

Results from the NITON XL3t Analyzer testing performed on the Gold King Mine Extension mineralized segments of the 'B' Vein over a 2.4 ft. drill width are set forth below:
