Colorado Goldfields Inc. Merger Roll-Up Continues to Grow Shareholder Base and Value -- Roll-Up Growth Strategy Doubles Shareholder Base -- Part 2 Gold Stocks

LAKEWOOD, CO -- (Marketwire) -- 11/02/11 -- Colorado Goldfields Inc. (OTCQB: CGFIA) (PINKSHEETS: CGFIA) announced yesterday that the Company has entered into a Memorandum of Understanding ('MOU'), with American Sierra Gold Corp ('American Sierra'). The MOU, which provides for customary due diligence, intends to make American Sierra a wholly owned subsidiary of Colorado Goldfields Inc.

After successfully adding the Brooklyn, King Solomon, and the Pay Day and Rage uranium claim group to its asset base, the Company now continues its strategy to increase shareholder value by acquisition and merger.

'This 4th acquisition is a significant step not only in total growth, but represents a new level of attractiveness to many other mining companies. I believe this transaction will propel our roll-up strategy to a higher level. As our discussions with American Sierra continue, it becomes clear that the strategic expansion of our shareholder base opens up new growth prospects for our company and creates further potential for accessing external capital funding and new and valuable acquisitions aligned with our gold mining and milling rights roll-up model,' stated Lee R. Rice, President and CEO of Colorado Goldfields.

'The fact that American Sierra on behalf of the Company's over seven thousand shareholders showed this commitment to Colorado Goldfields strongly supports our business model and the course our company is taking. After four years of total and consistent dedication and perseverance in the face of a very challenging world-wide economic climate, the strategic expansion of our shareholder base and the strengthening of our capital base opens up new growth prospects for us and creates further potential for acquisitions,' said Stephen Guyer, CFO of Colorado Goldfields.
