Montello Successfully Runs 9 5/8 Inch Intermediate Casing & Penetrates Knox Formation at the John Bowen #2 Test Well in Morgan County, Tennessee

CALGARY, ALBERTA--(Marketwire - Sept. 13, 2007) - Montello Resources Ltd. ("Montello") (TSX VENTURE:MEO) is pleased to announce that it has successfully run 9 5/8" Intermediate casing and cemented it in place on The John Bowen #2 Well ("the Montello Well"). This procedure has been approved by "Tennessee Oil and Gas". Installed in the intermediate casing is a sub-surface Weatherford downhole deployment valve that can be activated to shut off the well. This valve has been function tested and will assist in high pressure snubbing operations if necessary. A formation leak off test has been performed which is important to help determine well control. The formation's breakdown pressure (how much pressure the formation can withstand at the bottom of the casing prior to breaking down and leaking into fractures closer to the surface) is believed to be one of the potential reasons why there is oil leaking to surface around the Howard-White #1 Well.

Montello is presently "drilling ahead" and taking geological formation samples every 10 feet. Hydrocarbons have been encountered in the samples and the rig continues to drill to the basement as programmed. To date, the rig has drilled to approximately 3,745 feet; this is deeper than any well in the immediate vicinity. The Knox formation was encountered at 3,511 feet. In some locations within the Appalachian Basin, "the Knox Group" has been known to be over 2,500 feet thick. On the upper section of the Knox, it appears through the analysis of drill cuttings that as much as 17 feet of porosity has been drilled through. Drilling speed at this depth is currently averaging 25 feet per hour and we are on target. With the sophisticated underbalance system that is being used on the well we are able to control our mud weight and our geological personnel are able to evaluate the drill cuttings continuously. The benefits from the Top Drive System are now being utilized effectively.

Montello's President and CEO, Bill Cawker, says: "I am pleased that we are now drilling ahead on the John Bowen #2 Well as planned and will continue to drill to a depth of between 7,000 to 9,500 feet to hopefully discover one or more high pressured zones that were encountered in the offset wells. The Howard-White #1 Well (located 1.25 miles away) was drilled to a depth of approximately 2,400 feet prior to blowing out and flowed at an estimated initial rate of over 400 barrels of light gravity crude per hour. Even though, according to Pryor Oil, the Howard-White #1 Well was also capable of producing in excess of 5 million cubic feet of gas per day, the Howard-White #1 Well was never re-drilled or placed on production as a result of regulatory issues relating to the blow-out. Montello looks forward to keeping everyone informed of drilling progress as deemed permitted."

Montello has recently received in excess of CDN $650,000 from the exercise of warrants and options which can be utilized for additional project land lease and land option agreements potentially for both sides of the border.

Sandra Marshall has stepped down as the Corporate Secretary for Montello effective September 1st, 2007. Ms. Marshall will consult periodically to help ensure a smooth transition on any outstanding files. The Board of Directors thanks her for her contributions and wishes her the best in her future endeavors.

About Montello Resources Ltd.

Montello Resources Ltd. (TSX VENTURE:MEO),, is an emerging, publicly traded company listed on the TSX Venture Exchange in Canada. Montello is engaged in high impact oil and gas exploration "hunting for elephants" in the Tennessee Appalachians as to a 55% earned interest, Austin Developments Corp., as to a 40% earned interest (TSX VENTURE:AUL) and Great Northern Oilsands Inc., as to a 5% earned interest (PINK SHEETS:GNNS). Montello commenced drilling The John Bowen #2 Test Well on August 15th, 2007. The Well is expected to take approximately 45 days to drill to a total depth of between 7,000 to 9,500 feet to tentatively test the Precambrian formation which lies directly above the Granite / Basement. Montello is and will be testing and evaluating the various formations while it drills the well under-balanced. The Morgan Highpoint Project is located in a part of the State of Tennessee where only a limited number of deep tests have been drilled. 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 that have been hired by Montello to drill the John Bowen #2 Test Well. Montello is also active in Alberta with a re-completion of a Mannville Well underway. A deep Rundle Test Well is also scheduled to be drilled on our Pincher Creek property before year end. These prospects lie in an active gas producing area and offset some of the largest producers in the Pincher Creek Field. The Pincher Creek Field has been one of the most prolific fields in Alberta having produced some 600 BCF of gas and over 1 million barrels of associated liquids.
