PARTICLE DRILLING TECHNOLOGIES RECEIVES RIG ASSIGNMENT FOR NEXT FIELD TRIAL

Houston - June 2, 2008 – Particle Drilling Technologies, Inc. (NASDAQ: PDRT) (the "Company") announced today that it has now been informed by its customer that the next field trial utilizing the patented particle impact drilling ("PID") system will be conducted in the Travis Peak formation on the same drilling rig as the previous test conducted in 2007. This particular drilling rig is currently drilling another well which should be completed in June. The rig will move to the new location and begin drilling the well on which PID operations will be conducted. The Company estimates that PID operations will begin on or around July 15, 2008.

Jim Terry, the Company's President and Chief Executive Officer, stated, "We have worked hard to prepare our system for field use and are very excited to have scheduled the next field trial. We would like to have returned to the field sooner, but as I have made clear in all of my prior communications, our schedule is completely dictated by our customer's drilling schedule. We and our customer wish to minimize the variables associated with this next test and the decision to utilize the same drilling rig for the upcoming test will accomplish that objective."

Terry went on to say, "In the meantime, we are ordering sufficient long-lead items and maintenance parts such that we will be prepared to drill back-to-back wells. The experience we have gained on the four previous field tests coupled with the confidence we now have in the new injection system should allow us to deliver a solid performance on the next well. Once the results of the next field trial are tabulated, we will announce the results as soon thereafter as possible.
