3 August 2010 Companies Announcement Office Australian Securities Exchange Limited 10th Floor, 20 Bond Street SYDNEY NSW 2000 Dear Sir, COMPANY PRESENTATION – ADDITIONAL INFORMATION MEC Resources (ASX:MMR) is pleased to provide the attached additional information supporting its presentation today at the Australian Microcap Investment Conference in Melbourne. The review of open file information by independent geophysical consultants Total Depth Pty Ltd has demonstrated features associated with the Gorgon Gas Field that have also been identified in the offshore Sydney Basin, along the margin of investee company Advent Energy’s PEP11 permit. The seabed pockmark features identified by Total Depth are geomorphologic features indicative of upward fluid flow and the venting of gas. The Gorgon field, along with many other gas accumulations offshore Western Australia, shows evidence of out-gassing and upward fluid flow which has resulted, in places, in both small scale and large scale depressions in the sea floor. These same features have been identified in the offshore Sydney Basin by Geoscience Australia and reported by MEC Resources to the ASX on 14 th September 2008 (“Geophysical Indications of Gas in the Offshore Sydney Basin”). MEC Resources believes these similarities provide further encouragement for the prospectivity of Advent Energy’s PEP11 project. Yours sincerely, David Breeze Media Enquiries: Executive Director Bill Kemmery MEC Resources Ltd Fortbridge Consulting PO Box 317 Tel: +61 2 9331 0655 North Perth WA 6906 Mobile: +61 400 122 449 Tel: +61 8 9328 8477 About MEC Resources ASX listed MEC Resources (ASX: MMR) invests into exploration companies targeting potentially large energy and mineral resources. The Company has been registered by the Australian Federal Government as a Pooled Development Fund enabling most MEC shareholders to receive tax free capital gains on their shares and tax free dividends. About Advent Energy Advent Energy Ltd is an unlisted oil and gas exploration company, held by major shareholders MEC Resources (ASX: MMR), BPH Corporate (ASX: BPH) and Talbot Group Investments. Advent holds a strong portfolio of exploration and near-term production assets throughout Australia. Advent’s cornerstone project lies off the coast of NSW in Petroleum Exploration Permit 11 (PEP11), and comprises gas prospects of multi-Tcf capacity. Advent Energy’s wholly owned subsidiary Asset Energy Pty Ltd will increase its interest from 25% to 85% of PEP11 by drilling the first well. Bounty Oil and Gas (ASX:BUY) will thereby reduce their interest from 75% to 15%.

Total Depth Gorgon 3D Seismic (sub-volume) collected over the Gorgon Field Seismic sections Gorgon 3D (shallow section). The screen capture on the right shows a single Geo- Population™ automatically identified using Seisnetics ™. This Geo - Population™ (Sea- floor surface) is one of “hundreds” of high quality horizons (Geo - Populations™) automatically seeded and extracted from the 3D sub-volume using technology inspired by the Human Genome project. The Sea-Floor has been characterised by several populations of waveforms. The largest Geo- Population™ for this surface is shown. The other populations associated with this surface contain genetically different waveforms. The user can choose to merge these sub-populations into a single Geo- Population™ if warranted.

Total Depth Geomorphology from Sea-floor amplitudes Pockmarks Pockmarks on the seafloor surface are geomorphologic features which are indicative of upward fluid flow and the venting of gas. The Gorgon field along with many other gas accumulations offshore Western Australia show evidence of out-gassing and upward fluid flow. This out gassing has, in places, resulted in both small scale and large scale depressions in the sea-floor. Automated Interpretation using Seisnetics Chandon & Gorgon – Page: 4
Total Depth Pockmarks: Evidence for Out Gassing Amplitude & TWT Amplitude While some pockmarks can be small and below the imaging resolution of conventional exploration 3D surveys, many (like those shown here) are much larger and can measure 100s of meters in diameter. Regionally, areas of higher density of pockmarks have contributed to slumping and sea-floor instability over large areas during the course of geological 300 m time.
