Platinum Energy Resources, Inc. Provides Operations Update for Tandem Energy Holdings

Platinum Energy Resources, (OTCBB: PGRIU) (OTCBB: PGRI) (OTCBB: PGRIW) ("Platinum") a special purpose acquisition corporation focused on the energy industry, today announced an operations update for the first five months of 2006 for Tandem Energy Holdings, Inc. Platinum Energy had previously announced that it entered into a definitive merger agreement to acquire Tandem. In connection with the acquisition, Tandem has provided to Platinum Energy detailed information regarding its production, operations and prospects, from which the information described in this operations release is derived.

Operations Overview

During the first quarter of 2006, Tandem, as operator, drilled, reworked or recompleted 12 wells in four of its nine operated properties. As of May 31st, total proved reserves for Tandem were estimated to be 9,460 MBOE. This includes 3,300 MBOE proved developed producing reserves, 6,027 MBOE proved undeveloped reserves, and 133 MBOE proved developed non-producing reserves. This is an increase of over 120 MBOE in PDP reserves from the Dec 31, 2005 reserve report.

Mr. Jim Dorman, Executive Vice President of Platinum stated, "Given Tandem's two drilling rigs, four pulling units and other field equipment, as well as the talent and experience of Tandem's management team, Platinum will be well placed to make substantial additions to the 9.5 MM BOE of proved reserves of Tandem, once the acquisition is complete. Furthermore, using Tandem's base of operations, a stepped up development program calls for the additional drilling, reworking, and recompletion of approximately 100 new completions per year."

"There are many opportunities by which we can expand proved reserves. We believe that the proved reserves are underbooked, as there are typically two to four proved undeveloped locations booked for each proved developed producing well, whereas Tandem has less than one per well," continued Dorman. "Most of Tandem's proved undeveloped oil wells are currently booked at half of the expected production, based on what was recovered from historical analogs. Also, minimal behind pipe reserves have been booked, although we have identified many recompletion opportunities."

Ball Lease

During the first quarter of 2006, on the Ball Lease in Palo Pinto County, Texas, five new wells were drilled and two wells were recompleted with initial production adding approximately 100 BOE per day net to Tandem. This lease is sparsely drilled, has over 200 feet of Barnett shale below existing producing reservoirs and has shallow sand development that has never been tested on the lease. This potential significant upside has been identified by Platinum's geologic staff and Tandem's engineering group, and will be evaluated immediately after closing of the acquisition of Tandem.

Ira Unit

On the Ira Unit, located in Scurry County, Texas four new wells were drilled during the first quarter of 2006. This new drilling resulted in at least an additional 50 BOE per day net to Tandem. One of the new wells was drilled horizontally at a true vertical depth of 1,800 feet with a 1,100 foot horizontal displacement. The well has been fracture stimulated and is currently being evaluated.

According to Toben Scott, drilling engineer for Tandem, "This is our first use of horizontal drilling techniques, and it was accomplished using our existing equipment and infrastructure. We believe that horizontal drilling has the potential to double or triple the increase in production per well over a typical vertical well with less than a 25 percent increase in drilling cost."

Ballard Unit

Activity on the Ballard Unit, located in Eddy County, New Mexico has resulted in one new well during the first quarter of 2006. This well, the Ballard Grayburg San Andres Unit #26-6, has stabilized production of approximately 28 barrels of oil per day from the San Andres interval. Tandem is currently drilling another well in this unit and completion operations are ongoing on two other newly drilled wells. This unit is a prime candidate for downspace drilling and enhanced water flood expansion. During June and July, 2006, it is anticipated that an additional four wells will be drilled on the Ballard Unit.

Tomball Wilcox Drilling and Shallow Gas Reserves

During September 2006, it is anticipated that deeper drilling equipment will be available to drill a 9,000 foot Wilcox test on the Tomball property located in Harris County, Texas. Along with this new well, Tandem is planning a re-entry well in the same fault block to exploit the potentially significant Wilcox reserves.

Tandem recently completed a gas well at approximately 650 feet with initial net production of 130 MCF per day of dry gas. Reserves for this well have not been booked as yet, however it is anticipated that this shallow gas opportunity will be expanded in the future. Additionally, over 20 plugged and abandoned wells originally drilled by Exxon have been identified on the Tandem lease as potential re-entry candidates. These wells have been drilled to depths exceeding 5,000 ft and may have multiple productive pay zones that have not been included in the company's proved reserve report.
