Colorado Goldfields Inc. Announces Accelerated Exploration Plan for Brooklyn Mine; Historic Resource Grows to $21.8 Million in Value Gold Stocks

LAKEWOOD, CO -- (Marketwire) -- 05/10/11 -- Colorado Goldfields Inc. (OTCQB: CGFIA) (PINKSHEETS: CGFIA) announces an accelerated exploration plan for its Brooklyn Mine property.

Colorado Goldfields entered into a lease with an option to purchase the property in September 2009. At that time, the historic resource was valued at $13.8 million based on a gold pricing of $950 per ounce. With gold prices at approximately $1,500 per ounce as of May 6, 2011, the current value of just the historic resource is estimated to be $21.8 million.

Colorado Goldfields' personnel have completed an extensive review of all available information concerning the exploration, past production, and the existing historic resource estimate (14,535 oz. gold at $1,400/oz., $20.4 million) of the project area, and have developed a specific and dynamic strategy for exploration -- beginning with the Rainbow Trench.

The Rainbow Trench is the intersection of the Rainbow and Gloucester Veins. Past samples from the Rainbow Trench returned elevated gold and silver values. The trench will be cleaned to expose a fresh rock surface, systemically sampled to verify the reported anomalous gold and silver values and geologically mapped to define the surface expression of the vein systems. 'We are targeting grades of 0.30 to 0.90 ounces per ton of gold, however the Brooklyn Vein has produced ore with grades as high as 30.0 ounces of gold per ton,' stated Jonathan Moore, Project Geologist.

Company management has determined an approach for the 2011 season that will be directed toward verifying previous sampling work and defining specific core drilling targets for the next phase of the exploration program. Since these activities represent minor surface disturbances and do not require re-opening existing underground portals, a formal prospecting permit and approval cycle will not be required and the work may commence immediately.

The site also contains 'wash tailings.' Wash tailings are the result of previous operations that screened and washed ore on site. Gold and silver was then recovered by gravity leaving some wash plant tailings piles. The wash tailings will be sampled to determine if they contain commercial gold and silver values that would warrant immediate processing.

Using state-of-the-art software, the Company is developing a three-dimensional model of the Brooklyn Mine. In addition to the usually expected geological results from the work described above, the surveying and geological mapping provides the necessary data to build the three-dimensional model.

'This development strategy was developed to respond specifically to the increase in metals prices. By identifying activities that hold both the highest gold potential and require the least disruption, the Company will be able to move forward far more quickly than originally contemplated,' stated C. Stephen Guyer, Chief Financial Officer for Colorado Goldfields.
