LAKEWOOD, CO -- (Marketwire) -- 07/10/12 -- Colorado Goldfields Inc. (OTCQB: CGFIA) (PINKSHEETS: CGFIA) announces that it has retained Knight Piésold, the preeminent international engineering firm in the area of dry stack tailings management, to join the team constructing the final details of the reclamation permit amendment application. Furthermore the Company has authorized Bryan Ulrich, Senior Vice President for Knight Piésold, to speak directly with the State of Colorado Division of Reclamation, Mining, and Safety.

"There simply is no better engineering firm that could be chosen to complement the current engineering staff. We are pleased that Knight Piésold, who visited the Pride of the West Mill in the fall of 2011, took such an active interest in the project," stated C. Stephen Guyer, CFO for Colorado Goldfields.

Knight Piésold has been involved in the design of tailings management facilities for over 400 mining projects throughout the world. They have extensive experience with all types of tailings management systems, and have pioneered the development of alternative tailings management technologies such as drained sub-aerial systems, thickened/ultra-thickened/paste tailings disposal, and dewatered 'dry stack' tailings systems. Knight Piésold has established strong working relationships with specialist groups that provide support for the design of tailings thickeners, slurry pipelines, filtering plants, and paste tailings plants in order to provide complete and comprehensive design and operational expertise for tailings management.

Notable recent Knight clients with designs comparable to the design constructed by Colorado Goldfields include: Fairbanks Gold Mining Inc. (FGMI), The Canatuan Sulphide Tailings Storage Facility in Zamboanga del Norte, Philippines, Quadra FNX Mining Ltd., located in Atacama Desert in Northern Chile, and most importantly Kinsevere Copper Mine, where Knight designed and is implementing their dewatering system at the Kinsevere Mine as well as providing ongoing monitoring, review and management of the dewatering system and other groundwater related activities.

Colorado Goldfields has received over $9 million in preliminary purchase orders for toll gold/silver ore milling in advance of the permit process completion from gold/silver ore mines in the area.
