Cub Energy Inc. Commences Drilling of Krutogorovskoye-7 Well

HOUSTON, TEXAS--(Marketwire - Sept. 11, 2012) - Cub Energy Inc. ("Cub", or the "Company") (TSX VENTURE:KUB), announces it has commenced drilling of the Krutogorovskoye-7 ("K-7") well. The well is operated by KUB-Gas LLC ("KUB-Gas"), a subsidiary in which Cub has a 30% ownership interest and is part of the Company's accelerated 2012 drilling program.

The K-7 will be a deviated well which will evaluate the potential of a structure defined by 2D seismic and will target reservoirs of the Moscovian and Bashkirian age. The well is expected to take 50 days to reach a planned measured depth of 3,200 metres at a true vertical depth of ("TVD") of 3,100 metres. The Company will use the K-200 drilling rig owned by KUB-Gas, which recently drilled the Makeevskoye-20 gas well.

RPS Energy, the Company's independent engineering firm, estimated Prospective Resources for the prospect being evaluated by the K-7 well at between 19.4 (3C) and 2.4 (1C) billion cubic feet ("Bcf") of natural gas with a Best Estimate (2C) of 9.0 Bcf.

Krutogorovskoye is a 1,100 hectare exploration licence granted to KUB-Gas in 2004. It is located near the city of Lugansk, approximately 105 kilometres to the southeast of the KUB-Gas licences at Olgovskoye, North Makeevskoye and Makeevskoye and adjacent to the KUB-Gas licence at Vergunskoye.

Defined Terms:

"Prospective Resources" are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development. Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates assuming their discovery and development and may be sub-classified based on project maturity.

"Low Estimate (1C)" is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities recovered will equal or exceed the low estimate.

"Best Estimate (2C)" is considered to be the best estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be a 50 percent probability (P50) that the quantities recovered will equal or exceed the best estimate.

"High Estimate (3C)" is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities recovered will equal or exceed the high estimate.
