Enertopia Signs AMI Participation Agreement

VANCOUVER, BC – September 19, 2013 - Enertopia Corporation (ENRT-OTCBB) (TOP-CNSX) (the "Company" or "Enertopia") announces that the Company has signed the Definitive AMI Participation Agreement for development drilling of 100 light oil locations covering an area of 2,924 acres in a known field located in the Forest and Venango counties, Pennsylvania.

The light oil assets include a number of original oil-in-place pools in NW Pennsylvania discovered and developed by Quaker State Oil. Over the past 20 months the Vendor has drilled and completed 42 infill well locations with a 100% success rate. Each shallow oil well can have up to four separate producing sand intervals.

Enertopia issued 100,000 shares to the Vendor on closing. A further 10,000 shares will be issued per producing well, funded by the Company, with the potential for the total shares issued over four years reaching 1,000,000 shares for 100 producing wells.

Robert McAllister, President, stated: "This light oil project once drilled, looks to provide a strong and stable cash flow base and gives the Company the ability to appeal to diverse investors.”

This field development will provide the Company with the essential elements required to support a growth and income based business model:

• With CAPEX potentially as low as $130,000 per well it is expected that cash flow after initial CAPEX will allow the Company to fund the 100 well commitment;

• Vendor-reported expected light oil production field netbacks of approximately $55 per barrel basis $90 WTI should place the performance of these operations in the top 10% of all North American fields.

The Pennsylvania low risk light oil development project provides the opportunity to create value for Shareholders.
