Mammoth Energy Group, Inc. Reports That Oil Prices Return Above $83 per Barrel

WINSTON-SALEM, NC--(Marketwire - September 28, 2007) - Mammoth Energy Group, Inc. (PINKSHEETS: MMTE) reports that oil prices rose above $83 a barrel today as the weak dollar drove investors to the market and concerns remained about a decline in crude inventories at a key Oklahoma terminal.

Oil prices have risen to all-time highs in recent weeks, in part because the standoff between the West and Iran over its nuclear program has raised fears of a disruption in supplies from the Middle East.

''This is fueling speculation that a supply shortage could be seen mid-continent in the United States," said PVM Oil Association in Vienna.

"In my opinion, this is a prime example of why the United States should curb its dependency on foreign oil. There are plenty of domestic resources that can be tapped to provide necessary buildups of crude inventories," said Joe V. Overcash, CEO of Mammoth Energy Group, Inc.

Mammoth Energy Group, Inc. announced Wednesday that it has completed the acquisition of a fifteen percent working interest in 17 producing wells in Oklahoma.

Mammoth, through its newly created wholly owned subsidiary, United Gas OK, Inc. has acquired the working interest for shares of restricted stock valued at $225,000.00 based on partially completed engineering of the production. "This acquisition gives us needed immediate cash flow to fund our exploration and development strategies in Oklahoma," stated Joe Overcash, CEO.

The working interests are in gas wells in a field of approximately 1,045 acres. Mammoth expects more wells to be drilled on the acreage, possibly up to a total of 25 wells. The wells are currently cash flowing positive and a full accounting of the production and engineering of the wells is anticipated by the end of October.
