THE PROPERTIES

Since April 2006, JAG has held Oil and Gas exploration permits covering a total area of 332,790 hectares spread in three regions of Quebec: Témiscouata, Lac St-Jean and Charlevoix. During 2010, JAG transferred to Olitra title to the properties in exchange for 32,474,440 million shares of this corporation.

The Témiscouata property is part of the Appalachian Sedimentary Bassin (Lower St-Lawrence-Gaspé) and to date remains largely unexplored for its hydrocarbon potential. Surface geology shows evidence of potential structural traps and a succession of diversified sedimentary rocks, Shales, sandstone and carbonated rocks which could host potential oil and gas reservoir which led to JAG acquiring an interest in the area.

The Lac-St-Jean and Charlevoix properties are part of the Lower St-Lawrence Lowlands covering a sequence of sedimentary rocks sequences which are stratigraphically equivalent to the Trenton limestone and the Utica Shales.

More than $2 million has been invested to date in exploration on these properties since their acquisition. The exploration is lead by Dr. Marc Richer-Laflèche, P. Geo. and Professor at «Institut National de la Recherche Scientifique de Québec». The results obtained to date seem to indicate the presence of conventional natural on the Temiscouata property, and the presence of conventional natural gaz and liquid hydrocarbons on the Charlevoix and Lac St-Jean properties.
