/ Source: GlobeNewswire

PHOENIX, Dec. 15, 2010 (GLOBE NEWSWIRE) -- American Energy Fields, Inc. (OTCBB:AEFI) (the "Company") is pleased to announce that it has entered into an option agreement for the purchase of Prospect Uranium, Inc., a private Nevada corporation and a subsidiary of Tonogold Resources, Inc. (Pink Sheets:TNGL). The agreement gives AEFI a six-month exclusive option to purchase all of the issued and outstanding common shares of Prospect Uranium in exchange for an aggregate of 4 million common shares of AEFI, pending satisfactory completion of due diligence reviews by AEFI and Prospect and other customary conditions to closing. AEFI paid $15,000 for the option. The Board of Directors of Prospect Uranium and shareholders holding a majority of the outstanding shares of Prospect Uranium voting securities have already approved the transaction.

Prospect Uranium explores for and develops uranium mining properties primarily in North Dakota. Prospect Uranium's assets include uranium leases on approximately 1,026 acres of private property in southwestern North Dakota.  Historical estimates indicate approximately 8 million pounds of U3O8 in a four square-mile area including and surrounding the uranium leases. Drill logs show uranium mineralized roll fronts in sandstone, with uranium mineralization occurring within 350 feet of the surface. Additional layers of sandstone exist at deeper intervals but have not been cored or logged. Based upon historical data, the Company has identified the potential for development using either open pit or ISR mining methods.

AEFI would also gain the exclusive control of Prospect Uranium's historical exploration database. The database includes over 400 drill logs on and in the immediate vicinity of Prospect Uranium's North Dakota uranium leases. These exploration holes were drilled in the late 1970s.  Prospect Uranium's exploration database also includes data from various mining companies on mineral properties in Colorado, Wyoming, Nevada, and New Mexico.

Company President and CEO, Joshua Bleak, stated, "Our goal at American Energy Fields is to find, acquire, and develop natural energy resources in the United States. Prospect Uranium gives us a foothold in North Dakota, one of the most promising and under-explored areas for large uranium deposits in North America. Prospect Uranium's database of historical uranium exploration prospects should give us an inexpensive way to add quality properties to our portfolio. We look forward to updating you on the progress of this project as it moves forward."
