Custos Energy (Pty) Ltd.（“Custos”或“公司”）很高兴提供以下关于位于纳米比亚奥兰治盆地中心的 2813A 和 2814B 区块第二次勘探和评估活动的进一步更新，该区块正在成为世界上最具前景的石油和天然气地区之一。这些区块由石油勘探许可证 83（“PEL 83”）管辖，该许可证由 Galp Energia, SGPS, SA（“Galp”）的子公司运营。Custos 拥有 PEL 83 10% 的工作权益，纳米比亚国家石油公司 NAMCOR 也是如此。

我们很高兴地宣布，PEL 83 合资伙伴已成功钻探、取芯并记录了 PEL83 上的 Mopane-3X 井（井号 5），该井于 2025 年 1 月 2 日开钻。Mopane

-3X 距离第一口 Mopane-1X 井 18 公里，目标是两个叠层勘探区 AVO-10 和 AVO-13，以及更深的砂层，位于 Mopane 综合体东南地区，水深约 1,200 米。

初步数据证实，AVO-10 的优质砂岩中存在大量轻质油和凝析气柱。此外，在 AVO-13 和更深的砂层中也证实存在轻质油柱，同样是在优质砂岩中。

储层测井测量证实了良好的孔隙度、高压和高渗透率。初始流体样品显示油粘度低，CO2 和 H2S 浓度最低。样品已送去实验室测试。

Mopane 3X 高于预期的压力和初步结果为 Mopane 综合体东南地区带来了进一步的勘探和评估机会。所有获取的数据都将集成到油藏模型中，并支持规划潜在的进一步活动。专有的 3D 开发地震采集活动有望在 2025 年第一季度完成，随后将对获取的信息进行处理。

“在 Mopane 全新地段的这些额外发现进一步证明了该综合体的规模和质量。这一世界级资产为 Mopane 的多相潜力提供了新的清晰度，”Custos 董事长兼首席执行官 Knowledge Katti 表示。“我们祝贺我们的合资伙伴又一次安全而成功地完成了任务。我们位于这个碳氢化合物省份的中心，具有独特的优势，”他补充道。

Custos Energy (Pty) Ltd. ("Custos" or the "Company") is pleased to provide the following further update regarding the second exploration and appraisal campaign on blocks 2813A and 2814B located in the heart of Namibia's Orange Basin, emerging as the one of the world's most prospective oil and gas regions. The blocks are governed by Petroleum Exploration License 83 ("PEL 83") which is operated by a subsidiary of Galp Energia, SGPS, S.A. ("Galp"). Custos is a 10% working interest owner in PEL 83 as is NAMCOR, the National Petroleum Corporation of Namibia.

We are pleased to announce that the PEL 83 Joint Venture partners have successfully drilled, cored and logged the Mopane-3X well (Well #5) on PEL83 which spud on January 2nd, 2025.

Mopane-3X, located 18km from the first Mopane-1X well, targeted two stacked prospects, AVO-10 and AVO-13, as well as a deeper sand, in the southeast region of the Mopane complex at an approximate water depth of 1,200 meters.

Preliminary data confirmed significant columns of light oil and gas-condensate in high- quality sandstones across AVO-10. Further, the presence of light oil columns have been confirmed in AVO-13 and the deeper sand, again in high- quality sandstones.

Reservoir log measures confirm good porosities, high pressures and high permeabilities. Initial fluid samples show low oil viscosity and minimum CO2 and H2S concentrations. Samples have been sent for lab testing.

Higher-than-estimated pressures and preliminary results at Mopane 3X unlock further exploration and appraisal opportunities in the southeast region of the Mopane complex. All acquired data will be integrated into the reservoir model and support the planning of potential further activities. The proprietary 3D development seismic acquisition campaign is on track to be completed in the 1Q25, with processing of the information acquired to follow.

"These additional discoveries in an entirely new section of Mopane further demonstrate the scale and quality of the complex. An emerging clarity on the multi-phase potential of Mopane is underpinned by this world class asset," said Knowledge Katti, Chairman and Chief Executive Officer of Custos. "We congratulate our Joint Venture partners on another safe and successful outing. We are uniquely positioned at the heart of this hydrocarbon province," he added.
