John W Barr, Chairman, said:

"Mosman is pleased to report a significant uplift in annual net production, delivering on the strategic plan to increase production.

Whilst commodity prices are strong, workforce staff shortages due to Covid19 are affecting all operations and there is limited availability of drilling and workover rigs.

The Cinnabar well is planned and funded and is currently scheduled to spud in late August.

"The Company continues to maintain its portfolio of development and exploration projects, with a clear focus on its strategic plan to maximise the opportunity for further production growth and increasing cashflow. In addition to its USA projects, Mosman has two exploration areas in Australia which are well positioned to take advantage of the increasing demand for Helium and Hydrogen, in addition to oil and gas."

Further Details on Production

Winters-2 (23% Working Interest)

Production of gas from the Winters-2 well, which commenced in March 2022 continues and the June quarter is the first full quarter of production reported. Post the end of the quarter, a new compressor was installed at Winters and gross production is now regularly in the 0.7 to 1.0 MMBtupd range. That represents between 121 and 172 boepd (gross), which is a slight increase over the March quarter average of 123 boepd gross.

Stanley (34.85% to 38.5% Working Interests)

Stanley well production has been variable as workovers change production zones and gas infrastructure is optimised. Stanley-4 that was producing gas was worked over and is now producing oil.

Falcon (75% Working Interest)

The Falcon-1 well stopped producing in the June quarter and the first workover was not successful. Whilst this is an important project, the current priority is Stanley and preparing to drill Cinnabar. Further updates in respect of Falcon will be made as appropriate.

Livingston (20% Working Interest) and Greater Stanley (40% Working Interest)

These projects are of strategic importance and form part of the longer-term planning.

Arkoma (27% Working Interest)

Production had been variable since the significant lightning strike in March 2022.

This asset is being held for sale as other projects are preferred for further investment.

USA Development

Cinnabar Well (75% Working Interest)

Considerable focus during the last quarter was placed on the planning and actioning of the Cinnabar well.  This well is the next development well for Mosman.  If successful, once the geological model is updated, the potential for a number of wells on the lease is currently considered to be high.

This well remains on schedule to start drilling in late August, subject to site works and rig availability.
