Triangle Adds 500,000 Acre Shale Gas Exploration Project

CALGARY, ALBERTA--(CCNMatthews - May 31, 2006) - Triangle Petroleum Corporation (OTCBB:TPLM) (the "Company" or "Triangle") announces the following development in its wholly owned subsidiary, Elmworth Energy Corporation ("Elmworth").

Elmworth is pleased to announce it has executed a farm-in agreement with a Canadian company to pursue unconventional shale gas opportunities identified by Triangle and its US based partner, Kerogen Resources Canada ULC. The project covers approximately 500,000 acres and is believed to be located in a favorable geological setting based on technical work performed to date. Additional laboratory measurements are currently being performed on core samples and drill cuttings which were available on previously drilled wells.

Elmworth will base its drilling commitment decision on the results of the new geological studies and interpretation of the seismic available on the project area. The decision to drill will be made by mid-July. Elmworth has screened a number of Canadian shale gas areas and as a result of this screening and its active program in the Barnett Shale of the Fort Worth Basin, has focused on this potentially analogous and significant prospect. Complementary joint venture partners will be approached as the project matures.

Mr. Ron Hietala, President of Elmworth, comments "the identification and capture of our first Canadian non-conventional shale gas opportunity is an exciting time for Triangle. We are pleased to share this project on an equal basis with Kerogen Resources Canada ULC".
