Falcon-1 Drilling Update

Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces an update on drilling at the Falcon-1 well on the Champion Project in East Texas.

The well has been drilled to Target Depth of circa 7,762 feet. Several Frio sandstones were  intersected as expected and this has confirmed the geological model based on 3D seismic and nearby wells.

The next step is to run the wireline logs. Mosman intends to report on the results once these logs have been evaluated.
