Colorado Goldfields Inc. Completes This Year's Brooklyn Mine Exploration Plan -- a $22 Million Estimated Resource Gold Stocks

LAKEWOOD, CO -- (Marketwire) -- 09/28/11 -- Colorado Goldfields Inc. (OTCQB: CGFIA) (PINKSHEETS: CGFIA) announces that it has completed the 2011 exploration plan on the Brooklyn Mine. The overall goal of this year's exploration project was to confirm historic data on two major targets, including the sampling of the intersection of two veins, the Rainbow and the Gloucester. Historic sampling data indicates a probable zone of high grade gold in the intersection area. Sampling of this area has been completed. The Company is awaiting assay results, which should be available in the near future.

The second major sampling project was geochemical sampling of the property. Soil and/or rock chip samples on a grid system with sample lines 125 meters apart and 50 meters between sample points have been collected. The samples will be analyzed for the presence of 48 elements. The concentration of the 48 elements within the grid enables the Company's geologists to determine the shape and course of known structures and to identify structures which are not visible from the surface.

In addition to gold and silver, previous studies in the area have identified a number of trace elements in the vicinity of orebodies. Colorado Goldfields will closely monitor the data for indications of economically important elements, which include the rare metals tellurium and indium and monazite, which are essential to many of today's green technologies. Tellurium is known to be present in Brooklyn Mine ores. Indium is known to be associated with zinc in the district.

Although very speculative, historic information has revealed enough to warrant study of a possible intrusive breccia pipe. The area surrounding the Brooklyn is known for high grade ores contained in these breccia pipes, which geologists call 'spectacular.' Previous investigations have shown that a number of veins radiate from the possible breccia zone. One short crosscut into the zone indicates that ore grade silver might extend to the perimeter of the zone. This prospective pipe is known as the Growler Pipe.

Lee Rice, President and CEO of Colorado Goldfields, has provided proprietary high resolution aerial photos enabling the Company to better correlate the geochemical and geologic data with the surveys and surface appearance.

Upon completion of the geotechnical sample analysis, the diamond drilling plan will be prepared and application for drilling permits will be submitted to the state.

The geologic investigation was conducted by Monadnock Mineral Services under the supervision of Robert Larson. Mr. Larson is a graduate of the Colorado School of Mines with a degree in Mining Engineering. He is also a Certified Professional Geologist. Mr. Larson has extensive experience in the region having worked for Newmont (Idarado Mining Co), Ranchers Exploration, and Hecla Mining Co. Larson has extensive specific experience with the geochemistry of the breccia pipes.

'We are extremely pleased that the sampling program has been completed before the first snow in the high country. Analysis of the samples, preparation of the drilling permits, along with the continuing design of the dry stack facility for the mill can now continue uninterrupted during the winter months,' stated Stephen Guyer, CFO of Colorado Goldfields.
