Buccaneer Energy Plc

("Buccaneer" or the "Company")

Completion of £350,000 Fundraise

Buccaneer Energy (AIM: BUCE), the international oil & gas exploration and production company with development and production assets in Texas, USA, is pleased to announce a successful fundraise supported by a new cornerstone investor, institutional investor Premier Miton, alongside Directors and Management, existing shareholders and other new investors, to complete the acquisition of an adjacent producing asset and to expand the application of Organic Oil Recovery ("OOR") in the Pine Mills area (the "Field").

The Company has raised £350,000 (before expenses), c.US$472,500, through a subscription and placing of 3,500,000,000 ordinary shares (the "Fundraise Shares") at a price of 0.01p per share (the "Placing Price") (the "Fundraise").

Highlights

Use of Proceeds

The proceeds of the Fundraise will be used towards the funding of the Company's 100% WI acquisition of the Carlisle 1 well in the Fouke area of the Pine Mills field for a cash consideration of $425,000. The well is being acquired from a private Texas based oil production company.

The well is currently producing 25 bopd and will form part of the Fouke water flood unit. The well was previously owned by a private company and was not part of the development undertaken together by Buccaneer and its partner in the Fouke area. The well is located south of the Fouke 2 well and is producing from the same horizons as the Fouke 1 and 2 wells.

Funds will also be used to continue the Company's OOR program in the Pine Mills field.  A successful pilot program was initiated in the northern portion of the Field and delivered a 100% uplift in production rates in the treated area. The funds will support additional OOR treatments in the pilot area and expand the pilot program across the Pine Mills field, including treatment on the Carlisle 1 well.

Paul Welch, Buccaneer Energy's Chief Executive Officer, said:

"I am pleased to announce the successful completion of this fundraise, supported by both institutional and existing shareholders for the progression of our major operational program at the Fouke Area in East Texas.

The acquisition of the Carlisle 1 well adds immediate production of approximately 25 bopd net and strengthens our equity position in the proposed Fouke area waterflood unit, an important step as we focus on increasing recovery and production from this area.

Following this acquisition, Buccaneer's net production will increase to approximately 160 bopd. At current oil prices and with its low onshore operating costs, Pine Mills generates strong cash margins, and we remain focused on converting our existing NPV10 $9.6m reserve value into cash flow and shareholder value.

The funds also allow us to expand our OOR program in the Pine Mills field, where we have already seen a 100% uplift in production in our pilot area. Expansion of the pilot program is expected to further increase production across this mature waterflood asset. Additionally, the OOR knowledge gained in Pine Mills is directly applicable to the proposed Fouke area flood where we have the opportunity to expand further its application.

I would like to thank Premier Miton, alongside new and existing shareholders for their continued support. We have ambitious plans for this business, both organic and inorganic, and we look forward to sharing further updates with all our stakeholders in due course."
