Frontera Resources Announces Drilling Update at Shallow Fields
Production Unit

HOUSTON, TX -- (MARKET WIRE) -- 11/24/09 -- Frontera Resources
Corporation (AIM: FRR) (OTCQX: FRTE), an independent oil and gas
exploration and production company, today announced an update of
drilling operations at the Mirzaani #1 well that is currently
drilling in an underdeveloped portion of the Mirzaani Field within
its Shallow Fields Production Unit, Block 12, in the country of
Georgia. 

Open-hole logging operations have recently been completed at the
Mirzaani #1 well and, based on well logs as well as data obtained
while drilling, analysis indicates that the well contains
approximately 146 meters of total net sandstones with average
porosity values of approximately 20-25%. These Lower Pliocene age
Shiraki formation sandstones are distributed among seven known field
reservoir horizons, Zones 12-18, that are situated at depths between
approximately 1,200 meters and 1,490 meters. As expected, multiple
hydrocarbon shows were encountered while drilling. 

Located approximately 520 meters to the southwest and as much as 20
meters up-dip of the currently producing #73 well within the field,
the Mirzaani #1 well commenced drilling during the month of October
in the underdeveloped southeastern portion of the Mirzaani Field and
reached a planned total depth of approximately 1,500 meters during
the second week of November. 

Efforts are currently underway to prepare for production testing in
early December. 

Steve C. Nicandros, Chairman and Chief Executive Officer, commented:

"The successful drilling of the Mirzaani #1 well represents an
important step for Frontera in our progress to increase production
from the underdeveloped Mirzaani Field. Together with the results
seen in our analysis to date, the significantly improved drilling
performance of this most recent well compared to the drilling of our
first well in the field earlier this year provides us with further
encouragement for continued growth of the Shallow Fields Production
Unit." 

Discovered in 1932, the Mirzaani Field has historically produced
approximately 7 million barrels of oil, but contains many undrilled
locations across the structure. The Mirzaani #1 well is the second
new well to be drilled in the field since 1972. In 2006, Frontera
acquired approximately 100 kilometers of new seismic data over the
field area as part of an effort to re-map and identify new potential
associated with the field. Based on analysis to date at both fields,
Frontera estimates Mirzaani Field to contain over 50 million barrels
of prospective resources within the Shallow Fields Production Unit.
New reserve reports are expected to be completed following the
current work programs. 

Frontera's Shallow Fields Production Unit is located in the central
portion of Block 12 and represents what the company believes to be an
extensive trend of low-cost, low-risk oil and gas reserves. 
Containing four discovered yet undeveloped or underdeveloped fields
that have additional exploration potential, objectives are considered
to be traditional, well-known reservoirs of Pliocene and Miocene age
that are situated at depths from 10 meters to 1,500 meters.

undiscovered accumulations. Gerard Bono, Frontera's Vice President
and Chief Reservoir Engineer, who is a member of the SPE, is the
qualified person who reviewed and approved the statements in this
announcement and the prospective resources estimates associated with
the Mirzaani Field and Mtsare Khevi Field. These estimates are being
reviewed by Netherland, Sewell & Associates and will be released as
soon as practicable.
