Sionix Corporation Announces Recent Developments Related to the Williston Basin Project

LOS ANGELES, CA--(Marketwire - May 30, 2012) - Sionix Corporation (OTCBB: SINX) ("Sionix" or the "Company") is pleased to announce an expansion of our multi-year project to treat drilling fluids in the Williston Basin. In consultation with McFall, Incorporated, and upon the request of our Williston Basin E&P client, Sionix has agreed to a revision to the original parameters for the treatment conditions under which the current MWTS was configured. These new parameters increase the treatment level to produce an effluent significantly cleaner than required under the original treatment conditions.

Jim Currier, CEO of Sionix, commented, "Sionix has re-designed our MWTS in accordance with the requested treatment conditions and will deploy a modified solution that will meet these revised treatment parameters consistently. In fact, these new parameters reflect the trend in the Oil & Gas industry toward improved recycling and reuse efforts and are good for all parties. We believe the opportunity to provide an advanced level of treatment allows us to showcase our technical capacities to cover a wide range of fluids management and treatment needs."

The expansion of the Sionix treatment system targets the recovery of chemical compounds commonly used as a drilling lubricant. Recovery and reuse constitutes a significant economic benefit to operators/drillers in the Williston Basin as well as in other drilling operations in all of the shale formations in the continental United States.

Mr. Currier concluded, "The additional components will not involve significantly greater cost and are immediately available from multiple OEM and distribution sources. The modified MWTS will be reconfigured in the Williston area during the next two to six weeks by senior Sionix scientists, engineers, and technicians."

About the Bakken Shale Formation of the Williston Basin

The Bakken Shale Formation can be found in the Williston Basin, which stretches across North Dakota, Montana, South Dakota, Manitoba and Saskatchewan. In total, the basin covers roughly 300,000 square miles. The basin will become the second largest oil producing area as a direct result of hydraulic fracking, horizontal drilling, and artificial permeability practices. These technologies, using an average of 5 million gallons of water per well has created opportunities for water treatment and recycling that would ordinarily be disposed of in deep injection wells. Many industry experts believe these processes will liberate energy resources in 30 + shale formations across the United States and make the country substantially more energy efficient. Remediation of the large amounts of water necessary to support the energy harvesting activities are mission critical to the industry's sustainability, future expansion, and success. Sionix believes it is poised to be a key player in this water remediation process.
