Dear Sir/Madam

MEC Resources Ltd (ASX: MMR, ACN 113 900 020), the “ Company ”, is pleased to provide an update regarding the activities of its investee company, Advent Energy Ltd (“ Advent ”) in relation to its oil and gas assets.

PEP11, Offshore Sydney Basin, NSW (Advent 85%, Bounty Oil and Gas 15% working interest)

Advent has appointed SLR Consulting to conduct an independent assessment of marine noise generated by the planned 2D seismic survey to consider potential impacts on marine fauna in the area of the 2D seismic survey. It is anticipated that this will demonstrate a very low impact of the planned operations on the marine environment.

Advent has also advised that it has sourced a suitable provider of navigation services to ensure a seamless integrated 2D seismic survey is performed. A suitable contract for these services will be developed prior to commencement of the planned survey.

Furthermore, Advent has progressed its stakeholder consultation process in advance of the planned 200 line kilometres of 2 dimensional seismic data acquisition in PEP11. This is an essential component in the development of the Environmental Plan (“EP”).

A meeting of representatives of Advent with relevant stakeholders, kindly facilitated by the NSW Professional Fishermen’s Association, has been scheduled for the next week in Newcastle, NSW. Meetings are scheduled to ensure Advent meets its obligations under the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009. They will consider potential impacts of Advent’s planned seismic operations on relevant stakeholders and other users of that marine environment.

Advent’s EP will be submitted and approved by the National Offshore Petroleum Safety and Environment Management Authority (NOPSEMA) prior to commencement of seismic acquisition activities in PEP11. It is expected that Advent will commence its 2D seismic program in the third quarter of 2017.

Yours faithfully
