CORRECTION FROM SOURCE: Montello Resources Ltd. Announces Alberta Exploration Program

Montello Resources Ltd. (TSX VENTURE:MEO) - 

On the press release issued for Montello Resources Ltd. on Thursday August 23,
2007, we have been advised by the company that in the 4th paragraph, 18,000 BCF,
24,000 BCF and 30,000 BCF should have read 18.0 BCF, 24.0 BCF and 30.0 BCF
respectively. The correct release follows.


Montello Resources Ltd. is pleased to announce the signing of a Letter of Intent
(LOI) along with an AFE to participate in the Mannville Re-Completion of the
Pennine et al Pinh Ck 1-11-4-29W4M well at Pincher Creek, Southern Alberta
starting on or before August 31st.


Montello is farming into the PN&G rights held by Pennine Petroleum Corporation
("Pennine") in the Pincher Creek area of Southern Alberta. Montello shall also
have the right of Option, to be exercised within 45 days of notification, to
participate as to a minimum of 25% of Pennine's interest in the drilling,
completion, or abandonment of any proposed well on the lands held by Pennine
within the area of Township 3 and 4 Range 28 to 29 W4M. These lands are approx.
175 kilometres south of the City of Calgary, and consist of both Crown leases
and Freehold leases representing 10,560 gross acres (approx. 4,851.2 net acres
to Pennine). There are several projects in the Pincher Creek area for example
the upcoming "Upper Zones Play" mentioned below, which both companies feel
represents an opportunity to undertake immediate operations to obtain production
and prove up additional target wells for revenue enhancement.


Montello is farming in for twenty five percent (25%) of the re-completion and
testing of the Brown Sand and Mannville formation of the well bore "Pennine et
al Pinh Ck 1-11-4-29W4M". Pennine is the Operator and has a Working Interest
(WI) of 37.5%, and plans to re-complete the 1-11 well on or before August 31st
in the Mannville Sands with Montello, Paramount Resources, and a Private Company
as the Joint Venture Partners. This prospect has similar characteristics to a
Chamealo well producing 125 BOPD and 3 MMCFD re-completed in 2006 in the Lookout
Butte field, approximately 15 kilometres to the south of this location. The
Pincher Creek prospect has tie-ins to local facilities and has shown a total
possible raw gas reserve of 16.92 billion cubic feet (3.81 million cubic feet
potential to the companies), based on a December, 2006 Report of an Independent,
Calgary Engineering Firm. It is believed that each of two zones being tested is
of similar reservoir quality.


Next up, Montello shall have the option to be exercised within 45 days of
notification, to participate as to a minimum 25% of Pennine's interest in the
drilling, completion or abandonment of the proposed deep Rundle Test Well to be
drilled at the location of 6-12-4-29W4M4. Pennine again will be the Operator of
the Rundle prospect in the Pincher Creek Area and intends to drill at least one
well into the Rundle formation on or by December 31st, 2007. There is Rundle
production within two miles of the prospective location. The Rundle zone is
expected to be encountered at a depth of 3,880 metres. An independent third
party Calgary engineering firm has estimated the prospective resources range
from 18.0 BCF (raw gas reserves) low estimate, to 24.0 BCF with best estimates
up to 30.0 BCF - high estimate. It is believed given full 3D Seismic, that there
is an untested imbricate thrust fault that lies out in front of the northern
part of the main producing Rundle Formation imbricate. Since this project is in
an active gas producing area, the predominant risk is the possibility of the
well not encountering a reservoir of sufficient quality to yield the expected
rates and drainage area as predicted, or that the target sheet is not isolated
from the producing reservoir. A probability of 36 % has been estimated for the
best estimate case.


About Pincher Creek

The Pincher Creek Field has been one of the most prolific fields in Alberta. It
is a structurally-controlled, over-thrusted imbricate stack that has been
producing since 1947 and to date has produced some 600 BCF of gas and 1 million
+ BBLs of associated liquids from the Mississippian-age carbonates of the Turner
Valley (Rundle) formation. It is believed that an estimated 225 BCF of gas
remains to be produced from the Mississippian formations in the productive
plates that have been accessed thus far, although present production from
Pincher Creek is 2 MMCFD. Palaeozoic carbonates have been prolific targets in
the region with the Waterton, Turner Valley, Coleman, Savanna, Lookout Butte,
Jumping Pound, etc., fields having produced many TCF of gas and hundreds of
millions of barrels of associated liquids. However, due to the time of discovery
and the focus on the Mississippian carbonates as the objective target, little
attention was paid to the overlying Cretaceous and Jurassic sections that were
effectively by passed through en route to the Mississippian below - especially
once the initial discovery was made and subsequent drilling was
development-driven. Only seldom were any of the uphole zones evaluated in any
fashion, however limited testing indicated that there were uphole hydrocarbon
accumulations. These zones were not considered of interest at the time,
especially with the prolific Mississippian as the development target.


The most promising uphole zones identified thus far are the Lower Cretaceous
Cadomin and Lower Cretaceous to Upper Jurassic Kootenay / Nikanassin (Brown)
sand units. The Cadomin is the primary producing zone in the northern fields
while the Kootenay equivalents are productive in the Turner valley. Analogous
zones in recent Talisman wells typically have Initial Production and sustainable
production rates of 2.0 MMCFD and 100 BOPD respectively. Individual wells
typically have cumulative production values of between 3 BCF and 6 BCF for the
Cadomin and Brown sands respectively. These uphole zones at Pincher Creek are
structured and sometimes imbricated in a continuation of the same over thrusting
episode that affected the underlying Mississippian carbonates.


The concept for this uphole zone play is simply to follow sand development
across the Pincher Creek structure and access these hydrocarbon-bearing sands
via existing wellbores - possibly leading to drilling development. Montello is
very enthusiastic about the opportunity here and is looking forward to a close
JV Relationship with Pennine.


About Pennine Petroleum Corporation

Pennine Petroleum Corporation is an emerging Alberta-based junior oil and
natural gas company with projects located in Western Canada and selective

About Montello Resources Ltd.

Montello Resources Ltd. (TSX VENTURE:MEO), www.montello.com, is an emerging,
publicly traded company listed on the TSX Venture Exchange, is engaged in high
impact oil and gas exploration "hunting for elephant(s)" in the Tennessee
Appalachians. The John Bowen #2 Test Well which commenced August 15th is
expected to take between 30 to 45 days to drill and test. On August 15th,
Montello with its JV Partners initiated drilling of the John Bowen # 2 Test
tentatively to the Precambrian/Granite-Basement. Its total depth is estimated to
be between 7,000 to 9,500 feet. Montello is and will be testing and evaluating
the various formations while it drills under-balanced. We will be using the
services of an independent Geologist and Geophysicist to evaluate and analyze
the logging data. The Morgan Highpoint Project is located in a part of the State
of Tennessee where a limited number of deep tests have been drilled from the
late 1960's through to the early 1980's. Nabors Drilling USA, Strata Energy
Services of Red Deer, Alberta and Pason Systems Inc. of Calgary, Alberta are the
current key drilling and service contractors to date.


Montello is commencing its Alberta Exploration Program by farming in on a
Mannville Re-completion to be started on or before August 31st. A Deep Rundle
Test is scheduled to commence on or about December 31st, 2007. Pennine Petroleum
Corporation will be the Operator. Internal engineering is being provided by
Randy Marshall, P.Eng. formerly the COO & VP of Engineering at Montello. These
prospects lie in an active gas producing area, and offset some of the largest
producers in the Pincher Creek Field. The Company believes great potential lies
in this field and is pleased to announce the commencement of its development
program for the area. The Pincher Creek Field has been one of the most prolific
fields in Alberta having produced some 600 BCF of gas and 1 million + BBLs of
associated liquids. It is believed that an estimated 225 BCF of gas remains to
be produced.
