Sintana advances Challenger deal, updates Orange Basin exploration plans

Sintana Energy CEO Robert Bose joined Steve Darling from Proactive to discuss the company’s progress on two major fronts: the advancement of its acquisition of Challenger and new developments across key blocks in Namibia’s Orange Basin. Bose reported that the planned acquisition of Challenger has now satisfied several significant conditions, including formal consent from ANCAP—Uruguay’s national hydrocarbon regulator—and confirmation from Chevron indicating no objection to the transaction. With these milestones achieved, the deal now only requires final approval from the TSX Venture Exchange. A Court Sanction Hearing, originally delayed following later-than-expected ANCAP approval, has been rescheduled for December 12. On 26 November 2025, Challenger confirmed that the Scheme of Arrangement received strong shareholder backing, with the requisite majorities approving both the Scheme at the Court Meeting and the related Special Resolution at the General Meeting. Pending court sanction, registration of the Court Order, and satisfaction or waiver of remaining conditions outlined in the Scheme Document, the transaction is expected to become effective on 16 December 2025. Bose also provided an important operational update on Blocks 2813A and 2814B in Namibia’s Orange Basin—one of the world’s most closely watched offshore exploration regions. The blocks fall under Petroleum Exploration License 83 (PEL 83), currently operated by a subsidiary of Galp. Sintana maintains an indirect 49% interest in Custos Energy, which itself holds a 10% working interest in PEL 83, giving Sintana an effective 4.9% carried interest. NAMCOR, Namibia’s state energy company, holds an additional 10% working interest. Major structural changes are underway at the asset level. TotalEnergies and Galp have agreed to a transaction that will see TotalEnergies assume operatorship of PEL 83 and secure a 40% participating interest from Galp, which presently owns 80%. As part of the agreement, the parties will initiate a multi-well exploration and appraisal campaign over the next two years, targeting at least three wells aimed at further de-risking the block and defining a potential first development hub within the acreage. The first exploration well under this new program is currently being assessed for potential drilling in 2026—positioning PEL 83 as a key contributor to the growing momentum in the Orange Basin and reinforcing Sintana’s strategic exposure to one of the most prolific emerging petroleum regions globally. #proactiveinvestors #sintanaenergyinc #tsxv #sei #otcqb #seusf #invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews #OilExploration #Namibia #OrangeBasin #EnergySector #PEL83 #RobertBose #GalpEnergia #Chevron #QatarEnergy #EnergyNews #ProactiveInvestors #2025EnergyTrends
