Vancouver, British Columbia – February 6, 2008 – Bighorn Petroleum Ltd. (TSX-V:BHP ) (“Bighorn” the “Company”)- The Company wishes to announce that its plan to merge with Flying A Petroleum Ltd. (“Flying A”), Wyn Developments Inc. (“Wyn”) and Tenaka Drilling Consortium Ltd. (“Tenaka”) into a newly formed Company (Canada Gas Corp), as previously disclosed, is proceeding as planned and a shareholders meeting to approve the amalgamation and other matters is expected to be called in the short term.

The shareholders of record at the time of the merger will receive a proportionate share of the shares of Canada Gas Corp. The share exchange ratio and/or other consideration to be tendered by each party involved in the merger will be determined through negotiation between parties upon review of tax, accounting, corporate and securities law issues.

The Company is pleased to announce that the partners in the Prophet River Project in Northeastern BC have made their payment to acquire the Block B Lands at Prophet River. In addition to acquiring the Block B Lands these payments remove a 12 1/2% royalty interest that was to be paid to the Operator on production from both the Block A lands as well as the Block B lands. These Royalties will now accrue to the Prophet River Partners, (Bighorn, Flying A and Wyn) and after the merger with Tenaka, will result in the four companies collectively owning a 100% interest in both the Block A and Block B lands subject only to government royalties.
Also in the Prophet River area, Petro Canada has exercised a right of first refusal on two sections adjoining the Company’s lands to the southeast of the Company’s d-60-E Mississippian discovery well. Accordingly, Bighorn, Flying A, Wyn and Tenaka’s Prophet River land holding interests have been reduced to approximately nineteen square miles from twenty-one. Petro Canada Ltd. has increased their activity in the region in the past year, in, around, and between the Prophet River and the Trutch properties. Funds received from Petro Canada Ltd. on the exercise of this right of first refusal were credited to the Companies.

The Company wishes to announce that further to its news release dated September 19, 2007 it has signed a Participation Agreement to participate in the drilling of two wells on the Helmet Project in Northeastern, British Columbia. The Company will have the right to earn a 100% working interest in two wells by paying 100% of the cost to drill and complete each well subject to a 15% royalty to the Operator plus government royalties. The spudding of the first well in this program will be in March 2008.

The Helmet Project will not be part of the merger with Flying A, Wyn and Tenaka but will be transferred into the Company’s wholly owned subsidiary, Bighorn Exploration Ltd. It is expected that Bighorn Exploration Ltd will be spun out as a new public company immediately prior to the merger occurring. The Company will seek shareholder approval of this spin-out at the same time it seeks shareholder approval of the merger.

Shareholders of Bighorn on the record date for the amalgamation shall become shareholders of Canada Gas Corp., (the share exchange ratio to be determined).

Each unit will consist of one common share of the Company and one warrant, with each warrant being exercisable into a share for two years at a price of $0.20. A finder's fee of a combination of cash, shares and/or warrants will be paid to eligible finders in relation to this financing, all in accordance with regulatory policies.

In addition to the above-mentioned hard dollar financing, the Company also wishes to announce that it will complete a flow through financing of 6,000,000 units at a price of $0.10 per unit. Each unit will consist of one flow-through common share of the Company and one non-flow-through warrant, with each warrant being exercisable into one common share for two years at a price of $0.20. A finder's fee of a combination of cash, shares and/or warrants will be paid to eligible finders in relation to this flow-through financing, all in accordance with regulatory policies.

BIGHORN PETROLEUM LTD. SPRING 2007 UPDATE

Vancouver, B.C. – April 16, 2007 - Bighorn Petroleum Ltd. (the “Company”) is providing an update of recent activities, including the Company’s natural gas exploration and development programs.

THE PROPHET RIVER NATURAL GAS EXPLORATION AND DEVELOPMENT PROJECT
A thorough review of all known data from the Prophet River Lands including 2D and 3D seismic as well as the d-60-E/94-G-15 exploratory well data, where the Company holds a 331/3% working interest,  has continued since the crew left the drill site late January 2007.  Upon the Operator’s interpretation of pressure, seismic, petrophysical and petrographic data, and confirmation of the results by the British Columbia Oil & Gas Commission, the d-60-E/94-G-15 well has been re-classified as an ‘Exploratory Wildcat Well’ and ‘New Pool Discovery’.

The Operator of the d-60-E/94-G-15 well has elected to convert its 35% working interest to a 12.5% non-convertible gross overriding royalty on Block A of the Prophet River project lands.  This election to convert now increases the Company’s working interest in the Prophet River Block A lands from 21 2/3% to 33 1/3%.  Further, the Company has confirmed its election to drill on the 10 square mile Prophet River option Block B lands, and has selected the first location.  The Company is required to spud a well on the Block B lands by March 31, 2008.
A “pool”, as defined in the Petroleum and Natural Gas Act, “is an underground reservoir containing an accumulation of petroleum or natural gas, or both, separated or apparently separated from another reservoir or accumulation.” 

THE TRUTCH b-A86-A/94-G-15 TRIASSIC HALFWAY DEVELOPMENT WELL
The Company announces the b-A86-A/94-G-15 Triassic Halfway development well, where the Company holds a 2.5% Gross Overriding Royalty, has been drilled to target depth.  Casing has been run and the rig has been released.  By drilling this well, the Company has now earned an additional six sections (6 drill spacing units).  On the Bougie Trutch lands, the Company has now earned a total of 18 Halfway focused sections (18 drill spacing units) from the surface to above the Slave Point Formation.

BIGHORN PETROLEUM COMPLETES THE PROPHET RIVER d-
60-E/94-G-15 EXPLORATORY WELL

Vancouver, British Columbia – January 29, 2007 – Bighorn Petroleum Ltd. (“the Company”) – The Company announces the Prophet River d-60-E/94-G-15 well has been successfully completed.

After perforating and a coiled acid wash, the Mississippian reservoir yielded an initial unstabilized gas flow of up to 7.943 MMcf.d. Pressure recorders are currently in the wellbore to determine pressure buildup while the well is shut in and provide insight into the scale of this new Mississippian discovery. The pressures and gas returns, coupled with known seismic and geological data suggests likely communication between d-60-E and the d-19-E Dome well (flow tested 9 MMcf.d.) five kilometers to the southeast as well as the Unocal-Suncor d-65-L (flow tested 10.779 MMcf.d.) approximately 24 kilometers to the South of d-60-E. The seismic also suggests this gas charged reservoir extends to the northwest. In addition, excellent gas detection also occurred in the Triassic Halfway Formation as the well encountered 23 meters of prospective pay. The gas shows, log analysis, and seismic data suggests this Triassic Halfway Formation extends northwest and southeast toward the c-97-D Amoco well (flow tested3 MMcf.d), approximately seven kilometers from the d-60-E well.

This well control with seismic interpretation suggests the Company could drill an additional four Mississippian and four Triassic Halfway development wells on the 11 square mile Prophet River ‘A’ lands, in which Bighorn has earned its 21 2/3% interest.

The Company also has an option to drill a well on the Prophet River ‘B’ lands by committing 33 1/3% of the costs to earn a 21 2/3% interest in 10 square miles of land to the total depth drilled. The ‘B’ lands drilling decision deadline has been extended until March 30th, 2007, with the spudding deadline extended until March 30th, 2008. Well control with seismic interpretation suggests the Company could drill an additional three Mississippian and three Triassic development wells on the 10 square mile Prophet River ‘B’ lands.

This equates to a potential of seven additional Mississippian and seven additional Triassic Halfway development wells across the 21 square mile Prophet River lands.

The Company is very pleased with these results and is designing a development program that will include the possibility of dual production from the Mississippian and Triassic Formations. The Company intends to apply for several Mississippian drilling permits and commence a Prophet River development program this summer. With success, production infrastructure could be in place on the Prophet River lands in early 2008.

BIGHORN PETROLEUM LTD. TO PRODUCE FROM 3 NATURAL GAS WELLS 1st QUARTER 2007

Vancouver, British Columbia – January 17, 2006 – Bighorn Petroleum Ltd. (the “Company”) announces three Trutch area Triassic Halfway Development wells are proceeding into production, a new Trutch area Triassic Halfway Development well is now planned for this winter season, weather permitting, and work continues on the Prophet River d-60-E/94-G-15 Slave Point Exploratory well.

Q1 2007 PRODUCTION

Both the FET et al Tommy c-25-A/94-G-15 and FET et al Tommy b-56-A/94-G-15 natural gas development wells have been successfully tested and completed, building upon the success of the FET et al Tommy c-36-A/94-G-15 Triassic Halfway discovery well, which test flowed 1.65 million standard cubic feet per day (mmscfd) after stimulation. The Operator, Focus Energy Trust (FET), is now equipping the c-25-A, c-36-A and b-56-A wells for production, and is extending pipeline from their existing infrastructure at Tommy Lake. FET will run 14,217 meters of six inch pipe from Tommy Lake to the c-36-A well, followed by a total of 1,688 meters of four inch pipe from c-36-A to the b-56-A and c-25-A wells. The Company has royalty interest is 2.5% on the farm-in interest of the participation partners of Flying A Petroleum Ltd., Wyn Developments Ltd. and Northern Hemisphere Development Corporation (“Royalty Interest”) and there are no cash commitments required. Production is to begin late February 2007. Initial production rates will be provided at that time.

THE BOUGIE TRUTCH b-86-A/94-G-15 TRIASSIC HALFWAY EXPLORATORY WELL

The Company has initiated another Trutch area Triassic Halfway exploratory well to be drilled before breakup, weather permitting. The Company is seeking a license transfer for the b-86-A/94-G-15 well (WA20151) and is currently negotiating for a rig and qualified operator. The b-86-A application was approvedby the BC Oil and Gas Commission last winter and is located north of the successful b-56-A well. By drilling b-86-A to total depth, the Company will earn an additional six sections (6 square miles) of the Bougie Trutch lands (for a total of 18 sections) from the surface to above the Slave Point Formation. The Company has already earned its interest in twenty-six sections (26 square miles) from the top of the Slave Point to the basement. In total, the Company retains an option to earn our Royalty Interest in up to forty-one sections (41 square miles) in the Bougie Trutch and Trutch East lands.

(“the Company”) - The Company announces it has acquired a 2.5% gross over riding royalty (GORR) in the Trutch East natural gas lease package (15 square miles) for two hundred and fifty thousand dollars ($250,000.00). Under the terms of the Trutch East Participation Agreement, the Company will have the right to earn a two and half percent (2.5%) rolling GORR interest in the 15 sections (15 square mile) Trutch East lands. This rolling interest will include all
zones from the surface through the halfway horizon. In addition the company wishes to announce the spudding of the c-25-A/94-G-15 Triassic Halfway Development well on these lands. Drilling is anticipated to require 7-10 days to reach total depth with approximately two weeks for completion. This location lies between the successful c-36-A/94-G-15 Halfway Exploratory Well on the Bougie Trutch property (test flowed 1.65 MMcf which the Company also has a 2.5% GORR) and Focus Energy Trust’s producing Tommy Lake Triassic Halfway Field. Focus Energy Trust (TSX: FET.un) is the project operator.

THE TRUTCH EAST PROPERTY
The Trutch East land package is located in the prolific natural gas producing Western Canadian Sedimentary Basin in northeastern British Columbia, on trend with the East to West industry expansion of pipeline and support infrastructure. The Trutch East lands consist of fifteen (15) sections (district spacing units) of which at least twelve hold the potential for a total of up to twenty-four (24) Triassic Halfway development wells (upon half-spacing drilling targets). The property adjoins the Company’s Bougie Trutch lands (26 square miles) and is situated between the successful c-36-A/94-G-15 Triassic Halfway Discovery well and the Tommy Lake Triassic Halfway Field. The prospective resource estimates for the Trutch East are estimated at sixty (60) Billion cubic feet (Bcf) of natural gas in the Triassic Halfway Formation based on both 2D and 3D seismic interpretation. There is no certainty that this prospective resource will be discovered.

Thomas W. Bainbridge P.Geol., is the qualified consultant for the Company’s natural gas projects and has reviewed and verified the contents including the “prospective resource estimates” in this news release.

FET et al Tommy c-36-A/94-G-15

The FET et al Tommy c-36-A well was spudded on December 12, 2005 and reached a Total Depth of 1275 meters on December 19, 2005 within the Triassic Montney Formation. Schlumberger well logs have indicated a (25.7 meter gross) Triassic Halfway Formation sandstone reservoir.  This well was perforated over a six meter interval and after a 4 day flow test the well was shut-in (January 9, 2006) with a final rate of 46.73 E3M3/d (1.65 Million Cubic Feet per day) on a 38.1mm choke. The British Columbia Oil & Gas Commission has confirmed this is a New Pool Discovery.  Two offsetting wells have been licensed by the Operator, Focus Energy Trust, for the upcoming 2006/2007 winter drill season, and if successful, these offset wells and c-36-A will be tied-in for production late 1st Quarter 2007. The Company has a 2.5% Gross Overriding Royalty (GORR) in this well and property.
FET et  al Trutch a-13-B/94-G-15

THE BOUGIE TRUTCH NATURAL GAS DEVELOPMENT PROJECT
As previously reported, the two “Halfway” wells drilled in December 2005 and January 2006 at Bougie Trutch were successful, as the Operator tested and set production casing on both wells. The BC Oil and Gas Commission also confirmed that the c-36-A well proved the existence of a new gas pool. In the upcoming 2006/2007 winter season, the Company will be building upon this success by drilling two additional “Halfway” formation delineation wells near the original C-36-A well. If successful, these three wells should be tied-in for production by March 2007. The company holds a 2.5% over riding royalty on this project.

THE TRUTCH EAST NEGOTIATIONS
The Company is also currently in negotiations to acquire an interest in a rolling option for up to 15 square miles of prospective natural gas leases adjoining the South and Southeast portions of the Company’s Bougie Trutch development project. 2D and 3D seismic has been completed on the property and further details will be provided upon successful completion of the negotiations.

BIGHORN PETROLEUM LTD. ANNOUNCES SPUDDING OF NORTHERN BRITISH COLUMBIA TEST WELL

Vancouver, B.C. – June 21, 2006, Bighorn Petroleum Ltd. (the “Company”) announces that the Prophet River slave point exploratory test well is scheduled to be spudded as of June 25, 2006. The Drilling of this well is expected to take approximately sixty-five (65) to seventy (70) days to reach total depth and an additional two (2) to three (3) weeks for completion. The drilling of this test well has been contracted to a Major Canadian Oil and Gas company.

The 3-D seismic data has been reviewed by qualified and experienced representatives of all partner Companies and the major Canadian oil and gas company. Their interpretation leads to the following analysis:

1.) The 3-D seismic indicates that the first zone in the Slave Point Formation is analogous to the nearby Adsett Slave Point Field (BCF gas estimated at 200 B.C.F.), and is stratigraphically equivalent to the 3D Seismic of that field.

2.) The Second zone in the Slave Point Formation is analogous to the nearby Clarke Lake Slave Point Field (production 1957 to date, 62.7 Billion cubic meters and 2.2 Trillion cubic feet potential resources). There are 3 additional multiple secondary targets identified, including the Halfway, Debolt, and Banff formations. The company will pay 33 1/3 % of the working interest costs to earn a 21 2/3% working interest in the Prophet River well and eleven (11) sections of section ‘A’ lands, and will earn this interest to the total depth drilled. Upon the drilling of the first Prophet River well, the Company will also earn the right to drill an option well on the ten (10) sections of the section ‘B’ lands adjacent to the section ‘A’ lands by paying 33 1/3% of the working interest costs of drilling the option well to earn a 21 2/3% working interest in the option
well and the ten (10) sections of the section ‘B’ lands.

BIGHORN PETROLEUM LTD. GIVES AN UPDATE ON ITS BOUGIE TRUTCH NATURAL GAS PROJECT IN NORTH EASTERN BRITISH COLUMBIA

Bighorn Petroleum Ltd. would like to update shareholders on its Bougie Trutch natural gas development program. In reference to the C-36-A well in which the Company has a 2.5% gross overriding royalty (GORR), the Company had a meeting last week with the working interest owners in the Bougie Trutch play and Focus Energy Trust (the operator). The operator updated the participants with respect to the results of this winter’s, two well drilling program. The two wells have been completed and flow tested and the results are currently being evaluated. The partners are working together to develop the scope of the 2006/2007 winter drilling program, the details of which should be available in August.

The C-36-A well was originally classified as a “Development Well” as defined by the Petroleum and Natural Gas Act; Drilling and Production Regulation, under the enforcement of the British Columbia Oil and Gas Commission. As such, per the section 57 (4)(a) The Operator of well C-36-A is entitled to keep well data confidential up until “2 calendar months after the date of release of the drilling rig for (the) well or portion of (the) well classified as a development well.”1 In light of The Operator’s interpretation of the C-36-A well and prior to the release of the well data, the C-36-A well was reclassified by the British Columbia Oil & Gas Commission at the request of the Operator to an “Exploration Wildcat” well. The completion results of this “Exploration Wildcat” well are now classified as “tight” at the request of the Operator and therefore no information on the well will be released until Feb 13, 2007 unless approved by the Operator.

Further to the above, Bighorn Petroleum Ltd. would like to add some clarity to the reclassification of this well. An Operator is not obligated to advise the partners in a well when requesting a reclassification, as was the case in this instance. The British Columbia Oil & Gas Commission, Resource Conservation Branch can reclassify a well when requested by the Operator, subject to the Petroleum and Natural Gas Act; Drilling and Production Regulation section 14 (4), stating that “if a well has been drilled, the well or a portion of it, on application by the operator prior to the release of information pursuant to section 57 (4), may be reclassified as an exploratory wildcat and designated as a discovery well if, in the opinion of an authorized commission employee, the drilling of the well or the portion of the well resulted in the discovery of a new oil or gas pool.” Section 57 (16) also stipulates that “if, as a result of the reclassification of a well or portion of a well as an exploratory wildcat under section 14 (5), and on approval of an application from the well operator, well reports and well data from each subsequent well in the pool must be held confidential by the Ministry and the Commission until the confidentiality period for the discovery well has expired or for the period specified under subsection (4), whichever results in the later date.” In reference to ‘Discovery” wells, the British Columbia Oil and Gas Handbook best describes the classification as one in which an “application for discovery well designation may be made at any time, and is often made when a well is completed for production, (adding that) the application must include geological, geophysical and engineering data and an interpretive analysis, which clearly demonstrate that a new pool has been discovered.”
