Primary Gets to Work in Montana

Primary Petroleum has commenced drilling on its two key prospects in Montana at an estimated cost of $5 million. The Teton and Saturn Prospect cover approximately 120,000 net acres.

The 3D seismic program on the Teton Prospect is currently under way. Surveying commenced, and shooting and recording is also under way.

It is anticipated that the field program will be completed by October 20th, with processing and interpretation finalized by November 20, 2007. Primary is projecting that the drilling of the first of the eight-well drilling program should commence in early December.

The key targets for these multi-zone wells are the Madison oil and Sunburst gas.
