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 14th 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 Executive Director MEC Resources Ltd PO Box 317 North Perth WA 6906 Tel: +61 8 9328 8477 Media Enquiries: Bill Kemmery Fortbridge Consulting Tel: +61 2 9331 0655 Mobile: +61 400 122 449

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%.

Notes: In accordance with ASX listing requirements, the geological information supplied in this report has been based on information

provided by geologists who have had in excess of five years experience in their field of activity. MEC is an exploration investment company and relies on the resource and ore reserve statements compiled by the companies in which it invests. All Mineral Resource and Reserve Statements have been previously published by the companies concerned. Summary data has been used. Unless otherwise stated all resource and reserve reporting complies with the relevant standards.

Gorgon 3D Seismic (sub-volume) collected over the Gorgon Field

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.

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

  • ther gas accumulations offshore

Western Australia show evidence

  • f 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.

Amplitude Amplitude & TWT

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 time.

Tel: +61 8 9382 4307; email: info@td.iinet.net.au Key Points: Total Depth Pty Ltd has partnered with SEISNETICS LLC to provide pre-interpretation services using a radically new methodology that delivers an unbiased extraction of virtually all surfaces from 3D seismic

  • volumes. Without human intervention, the volume is automatically

segmented and organized into populations of genetically related

  • waveforms. These populations, referred to as Geo-Populations™, consist of

Trough and/or Peak surfaces. The process is independent of and complimentary to all workflows currently undertaken by professionals interpreting 3D seismic data regardless of which seismic interpretation tools are used. Key Objectives: The rapid extraction of high-quality pre-interpretation surfaces from 3D seismic volumes will enable more focus on understanding the results and their economic potential; thereby reducing risk, accelerating the decision making process, better utilization of resources, time and corporate assets. Key Application Areas: Seisnetics™ has application in the many areas: Pre- interpretation, Processing QC, Time-Lapse (4D) and Modelling for Basin, Structural, Depth, Velocity and Migration Pathway analysis. The process has been successfully applied to the following seismic volumes: Time Domain: Full-Stack, Angle Stacks, Spectrally Enhanced, Pseudo-Impedance and

  • Reflectivity. Frequency Domain: Estimated Wavelet Spectra, Residual

Wavelet Spectra and Normalised attenuation spectra. Requirements: Copy of 3D data (i.e. processing Archive SEGY format), Loading Parameters and X,Y co-ordinates. Services and Deliverables:

  • Loading and QC of SEGY data volume into Seisnetics application.
  • Waveshape analysis & segmentation to identify Geo-Populations™ (peaks &

troughs).

  • Review of results.
  • Delivery of Geo-Population™ database as a Seisnetics viewer project.
  • Onsite training and review of results.
