First results from project

Watermark Global PLC 15 April 2008 Watermark Global plc ('Watermark' or 'the Company') Above expected first results from the Water Project for Western Utilities Corporation 15 April 2008 The Directors of Watermark are pleased to announce the first results, from the Council for Scientific & Industrial Research ('CSIR') pilot water plant, by its wholly-owned subsidiary, Western Utilities Corporation (Pty) Ltd ('WUC'). The pilot plant has now been operating for a month and results from the plant are extremely encouraging and well within expected results. The purpose of the pilot plant is two-fold, namely proof of the Company's concept and secondly, verification of mass balances, including by-products generated by the process that will form part of the commercialisation phase and could generate additional revenue. Although detailed mass balances are not yet available, this requires a further two to three month operational period of the plant. Chemical analysis of the water indicates that the Acid Mine water can be effectively treated through the CSIR process. The South African National Accreditation System ('SANAS') standard for industrial quality (SANAS class two) and the current results achieved are depicted in the table below: Criteria SANAS Class II Feed Water Product Water Specification pH 4-10 3.35 7.9 Total Alkalinity (TAlk) mg/l as CaCO3 No Spec 0 140 Aluminium (Al) mg/l 0.5 2.97 0.01 Sodium (Na) mg/l 400 46.5 53.2 Potassium (K) mg/l 100 4.4 4.8 Calcium (Ca) mg/l 300 205 75 Magnesium (Mg) mg/l 100 124.6 0.98 Total Iron (Fe) mg/l 2 182 0.3 Manganese (Mn) mg/l 1 63.7 0.09 Sulphate (SO4) mg/l 600 1910 90 Chloride (Cl) mg/l 600 44.5 49.5 Fluoride (F) mg/l 5 5.4 0.07 Silicon (Si) mg/l No Spec 11 0.45 The Directors are encouraged by the results and expect to provide further updates on the mass balances, operating and capital requirements for the construction of a 75 megalitre (per day) plant which has the potential to be expanded to 200 megalitre per day.
