About Mosman

Mosman (AIM: MSMN) is an Australia and New Zealand focused oil exploration and development company with a strategy to build a sustainable mid-tier oil and gas business by acquisition and organic growth.

Currently, Mosman has a total of seven permits and applications in New Zealand and Australia.

Petroleum Creek Project, New Zealand

The Petroleum Creek Project is a 143.6 sq. km low cost onshore exploration project located near Greymouth on the South Island in the southern extension of the proven Taranaki oil system. The project has a Mean Unrisked Recoverable Prospective Resource of 26.6 million barrels. In the first month of drilling, oil was discovered at Cross Roads-1 well which declared an Oil Discovery in June

of existing discoveries and additional exploration with both seismic and a multi-well drilling programme.

Officer Basin Project, Australia

Mosman has a 25% investment in the Officer Basin Project, a 22,527 sq. km large land holding with significant exploration potential, which lies in one of the more explored parts of the Basin with road access. The project area is in the Western Australian part of the Officer Basin and offers both conventional and unconventional potential with hydrocarbon shows reported and all elements of a petroleum system are present.

Amadeus Basin Projects, Australia

Mosman owns two granted Permits and one application in the Amadeus Basin in Central Australia. Mosman's holdings cover a total of 5,458 sq. km following the successful acquisition of Trident.

The Amadeus Basin is considered one of the most prospective onshore areas in the Northern Territory of Australia for both conventional and unconventional oil and gas, and hosts the producing Mereenie, Palm Valley and Surprise fields.

Otway Basin Project, Australia

Mosman owns 30% of VIC/P62 in the Otway Basin. The permit was recently renewed and is in relatively shallow water. The 70% permit holder funded a 3D seismic survey in 2013 at a cost of in excess of A$4.5 million.

Within the Otway Basin there is commercial production both onshore and offshore.
