QMASTOR SECURES RECORD CONTRACT WITH RIO TINTO

May 30, 2007

The Directors of QMASTOR Limited announce the signing of a major contract with Rio Tinto Australia for the provision of its Pit to Port.net and SMS3D.net systems for installation throughout Rio Tinto’s coal operations in Australia. This is the largest contract secured to date by QMASTOR with a revenue value expected to be in excess of $2.6 million spread over three years.

QMASTOR will provide Rio Tinto with a complete end-to-end supply chain, quality management and logistic solution for their four large coal operations in Queensland and four operations in New South Wales. Rio Tinto’s selection of the QMASTOR systems is further endorsement of the internally developed technology of QMASTOR.

At each site QMASTOR will install Pit to Port.net to provide:

• Pit to vessel supply chain management

• Inventory tracking, blending and grade control

• Despatch planning, forecasting and reconciliation

• SMS3D.net will be implemented to provide advanced three-dimensional stockpile management and modelling on plant feed and product stockpiles.

Mr. Trent Bagnall, Managing Director of QMASTOR Limited stated:

“The contract with Rio Tinto is further confirmation of QMASTOR systems being best-of breed solutions for major global resource companies. This contract follows similar implementations in other large resource companies such as BHP Billiton, OneSteel and Anglo Coal and is an acknowledgement of the innovation and dedication of the QMASTOR team.

Installation of the Rio Tinto contract will commence in the current financial year and enhance the profit for the year ending June 2007. The major revenue stream from the contract will be in the 2008 financial year and coupled with other committed revenue will ensure QMASTOR profitability flows through to the next financial year.

The expected profit for the year to June, 2007 will provide the QMASTOR Board with the opportunity to recommence dividends. The Board appreciate the need to reward our stakeholders who have been patient during this period of refining our product and converting the world’s largest resource companies to be supporters of QMASTOR.

We would like to thank Rio Tinto for choosing the QMASTOR solution and we look to working closely with them for an extension of the QMASTOR system across further arms of the Rio Tinto Group. The implementation of this contract means QMASTOR will now manage over 270 million tonnes of global bulk commodity movements per annum in coal, iron ore, bauxite and nickel.

Again I would like to extend my personal thanks to the QMASTOR team in achieving this major endorsement of their efforts”.

QMASTOR’s business model allows for revenue to be received up front as a licensing fee, a fee for installation and an annual maintenance fee over the life of the contract. Adding new users is an important part of the company’s strategy as it locks in future revenue. However, with each new client the company has the opportunity to on-sell enhancements as the company refines its product offering.
