The funding represents a key component in our strategy to develop the Company’s exciting Australian oil and gas prospects, in particular the PEL 182 Deep Coal Seam Gas prospect, a potential ‘company making’ opportunity, as well as our organic growth opportunities. We feel the timing is right to accelerate our growth opportunities. We are grateful to our shareholders for their continued support, and are pleased to offer the shareholders the opportunity to participate in the capital raising via the SPP.” PEL 182 Deep Coal Seam Gas Summary On 16 November 2022 Bass announced the results of an independent study into the prospectivity of the deep coals in this permit. The Deep Coal Gas Prospective Resource study quantified the gas contained in PEL 182 at a “best estimate” of 21 TCF of gas in place along with and accompanying 845 million barrels of condensate in place. The Moolion East deep coal prospect, with an assessed prospective resource of 568 BCF of gas and 22.7 million barrels of condensate, is wholly contained within Bass’ PEL 182 permit. This opportunity is on trend with the Beanbush gas field which has been the focus of efforts by the Santos led Cooper Basin Joint Venture to commercialise this deep coal resource (figure 1). Results from Santos’ well completion report has recently become open file, with the report containing valuable data to support Bass Oil’s activities in the region. The results of this well will be a key input that will inform the SLB study that seeks to capture the learnings and calibrate the geological and geomechanical models to assist in designing future wells so they can be drilled in a manner that mitigates against future drilling problems and maximizes the chance of delivering an economic outcome. Total net Permian coal thickness in the Patchawarra Trough Kiwi 1 Extended Production Test (EPT) Kiwi 1 was drilled in 2003 as an exploration well, resulting in a Triassic age, Callamurra Member gas discovery which flow tested at 9.6 million cubic feet per day on drill stem test. The discovery, which was drilled on a 2D seismic data set, was originally thought to contain a sub commercial quantity of gas. A 3D seismic survey was subsequently acquired over the area. Bass has interpreted the survey and upgraded the potential size of Kiwi discovery resulting in a revised assessment of a mean Contingent Resource of 5.24 BCF and a 3C Contingent Resource of 11.5 BCF.2 Wild Desert Rig 4 has been identified as the rig to be used to complete the Kiwi well and it is anticipated to be mobilised as soon as practicable. The results of the test will likely be known within 60 days of commencement or around mid-year. The EPT will aim to prove that Kiwi contains a commercial volume of gas, thereby providing a pathway for the Company to enter the tight eastern states' gas market. The Company has also identified other prospects and leads, on trend with the Kiwi that, as a result of a successful test, may be significantly upgraded. Ex PEL 90K block location map Exploration The southern Cooper Basin properties (ex PEL93) are prospective for oil potential and are on the southern extension of the prolific Western margin oil province in the Cooper Basin. The northern properties are prospective for liquids rich gas within and adjacent to the Patchawarra Trough. The areas host numerous gas fields in the Permian and Triassic aged sediments as well as a number of Jurassic oil fields. The prospectivity of these areas in being reviewed by the Bass geoscience team with the aim of delivering a portfolio of prospects with the potential to provide an organic growth path for the Company. 2 Bass ASX announcements 26/09/2023 and 15/03/2024 Use of Funds The funds raised from the Offer will be used by the Company as follows: Use of Funds Amount (AUD m) Kiwi-1 Extended Production Test (EPT) $1.4 PEL 182 Deep Permian Coal Seam Gas Studies $0.6 Other high-value oil development opportunities $1.0 Expenses related to the Capital Raise $0.1 Total $3.1 Placement Bass has successfully raised A$1,100,000 (before offer costs) through placement of 15,714,286 Shares to institutional, sophisticated, and professional investors, at the Offer Price of A$0.07 per Share.
