Temaris Cluster and Asset Details

• Temaris Cluster comprises Tembakau and Mengkuang fields, with over 250 bcf (~42 mmboe) of discovered gas resources, fully appraised and ready for development.

• Both fields are in shallow water (~70m), benefit from extensive 3D seismic, DSTs, and well logs, and are near existing infrastructure.

• Tembakau features three main Miocene gas reservoirs with high-quality methane, no CO2 or impurities, and substantial flow rates.

• Production plateau targeted at up to 100 mmscfd (~17 kboepd) using minimal, unmanned facilities and low-cost development modeled on DEWA ($5–$7/boe CapEx).

• Mengkuang offers incremental volumes with high-quality sands and proximity to infrastructure.

Exploration and Upside Potential

• Exploration upside in multiple horizons within and adjacent to the block could more than double current resources (~250 bcf).

• Seismic reprocessing and advanced geophysical analysis planned to de-risk additional prospects and guide future drilling.

• Near-field, low-risk exploration integrated with the development campaign.

• Opportunities extend into adjacent acreage available in the next licensing phase.

• Commissioned a CPR to independently assess contingent and prospective resources, supporting future financing.
