Mosman Oil and Gas (MSMNhas booked a loss of A$10.3 million for the year ended June 2025.

It was a crucial period of transformation, as the company completed its exit from legacy oil assets and repositioned as a helium company.

Accordingly, on a consolidated basis revenue was down, as a result of the divestment of the oil assets. But on a like-for-like basis, the company boosted revenue to A$504,000, up from A$186,000. This was mostly from the acquired production at the Sagebrush asset in Colorado.

The net loss - as exploration activities continued and impairment charges processed through - was A$10.3 million, but cash at year end stood at a healthy A$3.9 million.

Cash as at 25 September was A$2.6 million.

"The 2025 full year marked a transformational year for Mosman as we repositioned the business squarely towards helium - a critical and high-value global resource,” said Carl Dumbrell, executive chairman of Mosman. 

“With Sagebrush validated by independent resource auditing and on track for seismic acquisition and flow testing in fiscal year of 2026, we are entering a period of significant value-driving activity. The divestment of non-core oil interests has sharpened our focus and positioned us to move decisively in this new phase. I am confident that Mosman now has the assets, team and strategy in place to unlock substantial shareholder value.”

Mosman’s share price has been trending up since the late summer, as the company delivers on some key milestones. A new evaluation of Sagebrush conducted by Sproule has provided a solid foundation on which to build, and the company is confident that significant upside is available. Lots of local infrastructure is in place, so the portfolio has plenty going for it. Next steps will be turning aspiration into reality, and we await the results of further exploration with interest - in particular, the drilling planned for 2026.
