Falcon-1 and Operations Update

Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces an update in respect to the planned Falcon-1 well and the other USA workovers.

Site preparation has commenced at Falcon-1. This is a relatively simple operation adding a drill pad to an existing access road that exists for non Mosman producing oil and gas wells.  Drilling remains on schedule.

At the Greater Stanley Project, the Operator is now ready to commence the workover of the Duff well as soon as approval from the relevant authority is received, which is expected shortly.

The workover at Stanley-1 is currently ongoing. As soon as results are received Mosman will provide updates.

John W Barr, Chairman, said: "As noted previously Mosman's focus is on building its production base and with two workovers and two new wells planned and financed the Company is entering an important phase of development."
