PETROFRONTIER CORP. PROVIDES
OPERATIONAL AND CORPORATE UPDATES
Calgary, Alberta – September 4, 2012 (TSX-V: PFC) - PetroFrontier Corp.
(“PetroFrontier”) is very pleased to provide the following operational and corporate updates.

Operational Update
MacIntyre-2H
Completion operations at PetroFrontier’s second horizontal well, MacIntyre-2H located in EP 127, Northern Territory, Australia are currently underway but not yet completed.

Owen-3H
PetroFrontier’s third horizontal well, Owen-3H, located in EP 104, Northern Territory, Australia has successfully reached total depth. Final measured depth of the well was 2,153 metres, of which the horizontal section was 966 metres targeting the Lower Arthur Creek and Upper Thorntonia Formations. A multistage open-hole completion string has now been placed in the well in preparation for a completion program targeting the Lower Arthur Creek and the Upper Thorntonia Formations. During the drilling of the horizontal section at Owen-3H, numerous positive hydrocarbon indicators were observed including:
? Oil staining
? Milky yellow fluorescing cut
? Strong gas recordings of C1 to C5
? Petroliferous odour
? Oil spots in the mud at the shaker

On August 9, 2012, PetroFrontier announced that a total of 32.5 metres of core was cut and retrieved from the Owen-3 inclined wellbore. Core evaluations are ongoing and PetroFrontier is encouraged by the initial assessment of these cores, which seeped oil upon retrieval and had extensive fluorescence throughout. The well was also wire line logged with equally encouraging results indicating over 25 metres total of vertical thickness of hydrocarbon bearing formations.
PetroFrontier is very pleased by the results to date and the fact that three horizontal wells (MacIntyre-2H, Baldwin 2-H and Owen-3H) have shown very encouraging oil and gas indications. The completion and testing results from these three wells have the potential to add significant value for PetroFrontier shareholders. However, readers are cautioned that no reserves have been proven to date by any of these wells.

Corporate Update
PetroFrontier is conducting a non-brokered private placement of up to 15,384,615 units (“Units”) of PetroFrontier at a price of $0.65 per Unit for gross proceeds of up to $10,000,000 (the "Offering").

Each Warrant entitles the holder thereof to acquire one additional Share upon payment to PetroFrontier of $0.90.

If a Trigger Event occurs, the Warrant Expiry Date shall be accelerated to 30 business days from the Trigger Event date.
