Fo INVITATION TO PARTICIPATE: ENVIRONMENTAL MANAGEMENT PROGRAMME FOR EXPLORATION OF NATURAL GAS IN VARIOUS AREAS IN THE WESTERN CAPE May 2010 BACKGROUND INFORMATION DOCUMENT Introduction Advasol (Pty) Ltd launched applications for exploration rights in terms of Section 79 of the Mineral and Petroleum Resources Development Act (MPRDA), 2002 (Act 28 of 2002) in various magisterial districts in the Western Cape. Applications were registered under the following PetroSA reference numbers: PetroSA ref no: 12/3/1/181/1 - Struisbaai PetroSA ref no: 12/3/200/1 – De Hoop West PetroSA ref no: 12/3/197/1 – Offshore West PetroSA ref no: 12/3/198/1 – Offshore De Hoop PetroSA ref no: 12/3/196/1 – Infanta PetroSA ref no: 12/3/187/1 – Offshore East PetroSA ref no: 12/3/1/184/1 – Stilbaai PetroSA ref no: 12/3/199/1 – Mosselbaai West PetroSA ref no: 12/3/195/1 – Mosselbaai Figure 1 – Locality Map These applications for exploration of natural gas were submitted to the Petroleum Agency of South Africa.

Exploration for natural gas – methods Prospecting will entail desktop compilation of data acquired from previous studies and satellite and hyperspectral images into a computer-based geological model. Thereafter geophysical magneto-telluric and induced polarisation surveys will be conducted and integrated with historical data in order to define possible traps for gas and petroleum. A borehole (some 1000-1500 metres deep) is proposed which will be combined with the down-the hole geophysical logging and gas analysis. Should results prove positive, then further holes will be planned for drilling during a renewal period of the Exploration Right to assess the potential of the gas reservoir a accompanied by resource and reservoir modelling and preliminary financial and feasibility assessments. This will culminated in the planning of production boreholes. Timeframes are indicated in Table 1 below: Table 1-Time frames for project components No Exploration Stage Time Frame 1. Data Compilation and Desktop studies 2008-2009 Data compilation will be done with a GIS system accompanied by various database spreadsheets. 2. Satellite Image Processing and Interpretation 2009 Satellite and hyperspectral images will be acquired over the project area to assist with targeting of priority area particularly during the data compilation stage in the first year. 3. Magneto-telluric (MT) and Induced Polarisation (IP) surveys 2010 Magneto-tellurics is an electromagnetic survey techno logy that uses broadband natural energy sources sucha s lightning, solar activity and ionospheric resonances to induce current flow in the ground. Data are measured as electrical resistivities and correlate with lithology, structure, porosity and potential hydrocarbon occurrences. It is particularly useful when augmented with seismic data which shows stratigraphy but resistivity. Induced Polarisation can also be used to define resistivity contracts between gas-filled reservoir rocks and the surrounding strata. This survey will be conducted during the second year. Other methods Electronic data capture of all information into a GIS (ArcMap™) system and three dimensional reservoir modelling in Petra™. Various other proprietary software programmes which are routinely used in the petroleum exploration industry will be used to define the conditions of the reservoir rocks and the porosity and potential 3 gas content and yields of these reservoirs 4. Drilling End of 2010, Drilling will be done with rotary core drill rigs capable of penetrating to depths of after successful up to 2000 metres and these machines are routinely used in the petroleum completion of non- exploration environment. Drilling is expected to take from 4-6 months to complete invasive process the borehole. Solid core can be recovered and potential gas/petroleum bearing rocks can be contained in suitable canisters for a variety of tests to assist with defining reservoir conditions
