PARTICLE DRILLING TECHNOLOGIES, INC. ANNOUNCES $5.2 MILLION RIGHTS OFFERING

Houston - March 10, 2008 – Particle Drilling Technologies, Inc. (NASDAQ: PDRT) (the "Company") today announced that it is planning to conduct a rights offering to raise approximately $5.2 million for working capital and for general corporate purposes. In the proposed rights offering, all common shareholders will receive one non-transferable right to purchase 0.11025 shares of the Company's common stock for each share that they hold of record as of 5:00 p.m., central time, on March 17, 2008. As fractional shares of the Company's common stock will not be issued, in order to acquire one share of common stock in the rights offering, a rights holder will need to hold at least nine rights. Shareholders will be able to exercise their rights to purchase shares until 5:00 p.m., central time, on April 16, 2008. The subscription price will be $1.50 per share for each share purchased. Shareholders who exercise their basic subscription right will also be able to exercise an oversubscription right.

In conjunction with the rights offering, two existing shareholders (the "Standby Purchasers") have agreed to backstop the rights offering by agreeing to purchase any shares not purchased pursuant to the exercise of rights. To guarantee a minimum participation of the Standby Purchasers, the Company will grant the Standby Purchasers in the aggregate options to purchase up to 700,000 shares of common stock at the same price per share as in the rights offering. These options will expire on the same date as the rights offering.
