Mosman Oil Gas Regulatory News (MSMN)

22 November 2019

Mosman Oil and Gas Limited

 ("Mosman" or the "Company")

Amadeus Basin Permit EP145

Mosman advises that today the relevant Minister in the Northern Territory Government has advised Mosman that he has approved a 12 month suspension of the Year 3 work program commitments for the permit, and a corresponding extension of the permit term.

This is exactly the decision Mosman had sought and now the Company can move forward with the 2D seismic acquisition, seismic processing and interpretation and exploration well planning.

The Company is already progressing the work program having contracted a seismic acquisition contractor to undertake the work and has completed field visits during 2019 to assess the terrain and logistical requirements for the seismic survey. Mosman is also working closely with the seismic contractor to finalise submissions required to obtain approvals to acquire seismic. An Environmental Management Plan (EMP) has been prepared and submitted to the NT Department of Environment and Natural Resources (DENR) for a final review.

The next vital step will be the completion of a survey by the Aboriginal Areas Protection Authority (AAPA) to ensure no areas of cultural significance will be disturbed by the planned seismic activities.
