Geo Energy Resources Limited - Sustainability Report 2025

GRI 3-1 to 3-3 At Geo Energy, we understand the importance of managing emissions from our operations and remain committed to responsible business practices. Guided by our corporate social responsibility principles, we prioritise the safety and well-being of our people, protect the environment, and actively support the local communities where we operate. SUSTAINABILITY FRAMEWORK Materiality Assessment GRI 3-1, 3-2 In 2025, we carried out a benchmarking exercise to evaluate our performance against industry peers and engaged internal stakeholders to assess both the positive and negative impacts of our operations. This process enabled us to identify and validate material topics, ensuring that we focus on issues with the greatest impact on people, the environment, and the economy. These material topics were subsequently reviewed and approved by the Board. Geo Energy’s materiality assessment was prepared with reference to the GRI Standards 2021. In line with the GRI 3 guidelines, we assessed our material topics alongside the SGX 27 Core Metrics to ensure continued relevance. The outcome of this assessment remains consistent with the material topics identified in 2024 and we continued aligning them under the three key pillars of our sustainability framework. 11
