Maverick Energy Group Updates Drilling Forecast and Production Numbers for Big Foot Field (Press Release)

Tulsa, OK, May 4, 2007 (Pink Sheets News Service) — Maverick Energy Group Updates Drilling Forecast and Production Numbers for Big Foot Field

TULSA, OK - May 4, 2007 - Maverick Energy Group, LTD (Other OTC: MKGP) a member of Z2, LLC (Z2) is pleased to announce that production has steadily increased in the Big Foot Field in Frio County, Texas, where Maverick serves as the operator and is a member of Z2. Oil production in the Big Foot Field has increased from approximately 7,500 barrels of oil per month in August 2006 to in excess of 10,000 barrels of oil per month in March 2007.

Drilling operations in the Big Foot Field have also increased and are expected to continue increasing for the foreseeable future. Maverick's goal is to start drilling three (3) new puds (wells) in May and then keep up this pace by drilling three new wells per month in the Big Foot Field from here out.

"Each new well we bring online produces 18-25 barrels of oil per day on average as well as varying amounts of natural gas. Since we are usually able to get each new pud drilled and online (producing) within a one month timeframe, we could see as many as 36 new wells operating within a year. That could increase our overall production by as much as 18,000 to 20,000 barrels of oil per month. At current prices, that should translate into an additional $1,000,000 to $1,250,000 in revenue per month for Maverick and its Z2 partners. Revenue from a predicted 10-15 million additional cubic feet of natural gas per month could really make for a significant jump in revenues in the coming year," says Jim McCabe, CEO of Maverick Energy Group, LTD.

Drilling operations in the Big Foot Field are being funded through a $40,000,000 Advancing Credit Facility which Z2, LLC closed with Gasrock Capital, LLC in August of 2006

Maverick Energy Group Announces Initial Production Figures for 4th and 5th New Big Foot Wells and Latest Workover Well (Press Release)

Tulsa, OK, Apr 30, 2007 (Pink Sheets News Service) — Maverick Energy Group Announces Initial Production Figures for 4th and 5th New Big Foot Wells and Latest Workover Well

TULSA, OK - April 30, 2007 - Maverick Energy Group, LTD (Other OTC: MKGP) a member of Z2, LLC (Z2) is pleased to announce that production has begun on the fourth and fifth Big Foot wells, which are part of the operations planned by Maverick, as a member of Z2, with funding from the $40,000,000 Advancing Credit Facility which Z2 closed with Gasrock Capital, LLC in August of 2006. Each of these two wells is showing initial daily production in the range of 20 Barrels of Equivalent Oil (combined oil and gas production).

In addition, a well was re-entered nearby which has been completed in the "D" Zone and fraced at approximately 3,600-3,700 feet in depth. This well is also showing an initial average production rate of approximately 100 Barrels of Equivalent Oil per day.

"The results of the first five new wells Maverick has drilled in the Big Foot Field as part of the Z2 drilling program have exceeded our initial expectations. The three abovementioned wells alone should generate approximately $1,800,000 annually for Maverick and its partners in Z2. These production numbers are very significant and indicate that the data is correct in predicting large reserves still lying beneath the Z2 lease. This is extremely encouraging for the Z2 partners as well as for our financing partner, Gasrock Capital. When combined with the successes we are showing in our other drilling programs, this should be very good news for Maverick's shareholders. We look forward to continuing to expand production within the Big Foot Field while also evaluating other independent drilling opportunities as they arise," says Jim McCabe, CEO of Maverick Energy Group, LTD.
