UPDATE ON COMPANY ACTIVITIES

The Directors of Sub Soil Technologies Limited (“SOI” or the “Company”) are pleased to provide an update to shareholders regarding the Company’s activities.

Nutrimix and Soil Technology

Trials are underway to ascertain the composting time frame required to produce soil supplements, potting mixes and potentially a low cost organic fertiliser as part of the newly developed range of Nutrimix products.

Some 24 treatments have been established using the organic waste material from several agricultural industries and based on analysis of nutrients, combinations of these wastes form the basis of the materials tested during the trials. The results of these trials are expected within the next 4 to 6 weeks.

The initial visual changes observed by the testing team appear to be very encouraging as the compost treatments are rolled over to accelerate the breakdown of raw material into a finer component.

The waste materials chosen for these trials are those that are readily available adjacent to all major rural centres around Australia to enable any future manufacturing facility to be established close to source supply thereby minimising freight. This selective and simple approach to logistics will enhance the potential future manufacturing and sale of Nutrimix products and improve the potential franchising/ licensing opportunities in these centres.

During the trials special additives are also being used to augment some treatments to ascertain the changes in nutrient values when developing a product to meet the needs of different soil types.

The Company is also assessing the application of IEM (waste to clean food) waste technologies using alternative sub strait material for Nutrimix and will inform the market further as this progresses.
