Toronto, Ontario--(Newsfile Corp. - March 1, 2023) - CGX Energy Inc. (TSXV: OYL) ("CGX" or the "Company") announced today the release of its audited consolidated financial statements for the year ended December 31, 2022, together with its Management Discussion and Analysis (the "Financial Disclosures"). These Financial Disclosures will be posted on the Company's website at www.cgxenergy.com and on SEDAR at www.sedar.com. All values in the Financial Disclosures are in United States dollars unless otherwise stated.

Company Highlights:

Farm-In Transaction

On November 30, 2022, CGX and Frontera Energy Corporation ("Frontera") closed the previously announced (See July 22, 2022 press release) agreement to amend the Joint Operating Agreement originally signed between CGX and a subsidiary of Frontera on January 30, 2019, as amended, (the "JOA Amendment") effectively farming into the Corentyne block and securing funding for the Wei-1 well. As a result of the JOA Amendment, CGX now holds a 32.00% participating interest with Frontera holding the remaining 68.00% participating interest in the Corentyne block.

Kawa-1 Well

On May 9, 2022, Frontera and CGX, joint venture partners (the "Joint Venture") in the Petroleum Prospecting License ("PPL") for the Corentyne block, offshore Guyana, announced the discovery of 228 feet (69 metres) of net pay across the Maastrichtian, Campanian, Santonian and Coniacian horizons at the Kawa-1 exploration well, offshore Guyana. Third-party analyses indicated the presence of light oil in the Santonian and Coniacian, and gas condensate in the Maastrichtian and Campanian. The findings are consistent with discoveries reported by other operators adjacent to the Corentyne block and further de-risked equivalent oil targets anticipated at the Wei-1 well.

Wei-1 Well Operational Update

CGX commenced drilling operations on the Wei-1 well on January 20, 2023 and is currently at 15,400 feet measured depth. There have been no lost time, safety or environmental incidents since starting operations. Drilling operations have gone as planned and the first prospective geologic horizons in the Upper Maastrichtian, have been successfully drilled, several days ahead of schedule. Geophysical logs are currently being obtained in the open hole section within which hydrocarbon shows were encountered. When drilling operations resume, deeper prospective horizons in the Lower Maastrichtian, Campanian and Santonian sections will be targeted.

The Wei-1 well is located approximately 14 kilometres northwest of the Joint Venture's previous Kawa-1 light oil and condensate discovery and is being drilled in water depth of approximately 1,912 feet (583 metres) to an anticipated total depth of 20,500 feet (6,248 metres). The Wei-1 well is targeting Maastrichtian, Campanian and Santonian aged stacked sands within channel and fan complexes in the northern section of the Corentyne block. The well is expected to take approximately 4-5 months from well spud to reach total depth.

As previously announced on January 23, 2023, the Government of Guyana approved an Appraisal Plan for the northern section of the Corentyne block which commenced with the Wei-1 well. Following completion of Wei-1 drilling operations and upon detailed analysis of the results, the Joint Venture may consider future wells per its appraisal program to evaluate possible development feasibility in the Kawa-1 discovery area and throughout the northern section of the Corentyne block. Any future drilling is contingent on positive results at Wei-1 and the Joint Venture has no further drilling obligations beyond the Wei-1 well.

Berbice Deep Water Port

Work on in-river construction of the 50 x 12 m access trestle being built from the quayside yard westward into the Berbice river is progressing according to schedule; all pre-stressed concrete piles have been produced and delivered and the contractor has begun to install the piles in the Berbice river, together with necessary dredging operations. The Berbice Deep Water Port ("BDWP") facility intends to serve as an offshore supply base for the oil and gas industry and as a multi-purpose terminal to service agricultural import/export, containerized and specialized cargo including aggregates for construction purposes. The BDWP aims to enable provisioning of operators and vendors in territorial waters of both Guyana and Suriname.

Change in Directors

CGX today announced that Veronique Giry, a Frontera nominee to the CGX Board, has stepped down as a director of the Company, effective February 28, 2022, and that Mr. Orlando Cabrales Segovia, CEO and Board Member of Frontera, has been appointed to the CGX Board effective immediately. The CGX Board and management team thanks Ms. Giry for her service and participation on the CGX Board since June 30, 2021.
