CALGARY, ALBERTA--(Marketwire - Sept. 23, 2009) - TAMM Oil and Gas Corp. (OTCBB:TAMO) today announced that it has completed its necessary due diligence and internal geological assessments and has now closed the previously announced agreement to acquire an additional 7680 acres of Heavy Oil Leases and Petroleum and Natural Gas Leases in the Peace River region of Alberta from three private corporations. These new leases increase TAMM's land holdings in the Manning area to over 35,000 acres.

TAMM has issued in trust, pending full transfer of the leases, 17,000,000 restricted shares as consideration.

TAMM is presently commissioning an engineering report from a qualified independent Petroleum Engineering firm for a reliable determination of the estimated volume of original heavy oil in place within the consolidated acreage acquired at Manning to date.

The Engineering Report is intended to establish and quantify the amount of original heavy oil in place within in the Lower Cretaceous sands and Mississippian carbonates within the TAMM land holdings.

Don Hryhor, Director and Exploration advisor to the Board said, "The new lands acquired are complementary to our existing Manning holdings and are considered highly prospective.

"TAMM geologists have identified certain previously drilled wells in the region which show promising similarities (based on log analysis, lithological descriptions and hydrocarbon indications) particularly in comparison with other producing Mississippian carbonate oil wells in the Peace River region such as the Shell Chipmunk Field."

"The acquisition of these new properties is another significant milestone in TAMM's continued growth in the Manning area. This combined with the previously announced farmin agreement to acquire the Heavy Oil rights on up to 276,000 gross (138,000 net) acres in the Peace River area - has strongly positioned TAMM as a major player in the Alberta Carbonate Triangle which is estimated to host approximately 440 Billion Barrels of original heavy oil in place."

"TAMM intends to further examine geological information and acquire existing seismic data in order to define and high-grade recommended drilling prospects over the next few months. We anticipate drilling an initial well based on these findings during the upcoming winter season, and will determine locations for additional drilling of other prospects and follow up wells."
