WINSTON-SALEM, NC, Aug 21, 2008 (MARKET WIRE via COMTEX) -- Mammoth Energy
Group, Inc. (PINKSHEETS: MMTE) is pleased to announce today that the company's
first Oklahoma well has been fully completed and has begun commercial
production. The well began pumping on August 20, 2008 with an initial production
rate of 2-3 barrels per hour fluid recovery. The well is still pulling both oil
and acid water out at a current ratio of 30-50 percent oil to water. As we are
still recovering acid water from the acidizing process, the ratio will improve
as the acid water recovery diminishes.

"The growth of the company is beginning to take off," commented Joe Overcash,
Chief Executive Officer of Mammoth Energy Group. Overcash continued, "Our first
producing well is a big step for the company. We are confident that our other
wells will produce at similar rates, which will significantly increase both
revenues and net asset value for our shareholders."
