Block 2A is located offshore Sarawak, eastern Malaysia in the North Luconia hydrocarbon province covering approximately 12,000 km² in water depths between 100 -1,400 metres. Block 2A contains the world-class Kertang prospect, located across four Oligo-Miocene reservoirs, which can be summarised as follows:

• Well-defined, large, four-way dip structural high with over 220 km2 of closure;
• Covered by high-quality, wide-beam 3D seismic shot by CGG in 2015;
• Exhibits direct hydrocarbon indicators (DHIs) including an overlying gas cloud feature and amplitude brights;
• CPR undertaken by ERCE on Kertang in 2024 assigns total gross, unrisked mean prospective resources of 9.1 TCF plus 146 mmbbl of NGLs (~1.7 billion boe);
• CPR chance of success of ~20%;
• Bintulu LNG, one of the world’s largest LNG facilities, is located onshore Sarawak;
• Based on regional offset wells, third-party high-level cost estimates for a successful Kertang exploration well in excess of US$70 million (gross).

Block 2A was originally awarded to Seascape in February 2023 as part of the Malaysian Bid Round 2022 by PETRONAS Malaysia Petroleum Management (“MPM”). MPM acts on behalf of PETRONAS in the overall management of Malaysia’s petroleum resources throughout the lifecycle of upstream oil and gas assets. Seascape’s initial interest in Block 2A was 36.75% which was increased to 52.5% following the acquisition of Topaz Number One Limited in September 2023.

The Company undertook a farm out process in mid-2024 which culminated in a transaction with INPEX CORPORATION, Japan’s largest exploration and production company, where Seascape assigned operatorship and a 42.5% interest in the PSC to INPEX in return for:

• a full, uncapped carry for Seascape’s retained interest (10%) through the remaining exploration phase which includes one firm wildcat well and one contingent appraisal well (subject to a commercial discovery);
• initial cash consideration of US$10 million which was paid on completion in March 2025 together with the reimbursement of certain historic costs associated with the PSC totalling ~US$1.0 million; and
• further contingent cash consideration of US$10 million payable on a commercial discovery;

Seascape through its 10% retained interest still has a material exposure to the Kertang prospect with net unrisked mean prospective resources of ~910 bcf and ~15 mmbbl of NGL (~166 mmboe). A summary of the CPR published in June 2024 can be found on the Company’s website: https://seascape-energy.com/presentations-reports/.

In October 2024, Seascape was awarded a 28% participating interest in a Small Field Asset Production Sharing Contract over the DEWA Complex Cluster off the coast of Sarawak, Malaysia. The Award was made under the Malaysia Bid Round Plus by Petroliam Nasional Berhad  (PETRONAS).

DEWA is comprised of 12 gas discoveries in shallow water (40-50 metres) near to infrastructure off the coast of Sarawak and includes; D30, D30W, Danau, Daya, Daya North, D41, D41W, Dafnah West, Dana, Darma, West Acis and Spaoh. Gas was originally found in the area in 1982 but overlooked by previous partnerships which were focused on oil production.

The DEWA partnership is anticipated to focus initially on the D30, Danau, D41, D41W, Dana and Dafnah West discoveries which are estimated by Seascape to contain circa 500 bcf GIIP (gross, ~83 mmboe). These fields are broadly characterised as having clastic reservoirs with large gas columns and good hydrocarbon mobilities. There is a significant dataset including 35 well penetrations, well logs, multiple DSTs and MDTs as well as extensive 3D seismic coverage across the entire PSC area.

Given the shallow water depths and nearby infrastructure, the partnership is targeting a low-cost development plan utilising normally unmanned platform(s) with minimal processing which could support a potential production plateau of up to 100 mmscfd.

The initial low-cost work commitment (approximately $0.6 million net to Seascape) is to conduct a detailed resource assessment and deliver a Field Development and Abandonment Plan within two years. The development of these fields will be under the innovative, new Small Field Asset terms which are specifically designed to simplify and incentivise rapid development of smaller hydrocarbon accumulations in Malaysia.

In June 2025 Seascape was awarded a 100% participating interest as operator in a Small Field Asset Production Sharing Contract over the Temaris Cluster offshore Peninsular Malaysia. The Award was made under the Malaysia Bid Round 2025 by Petroliam Nasional Berhad (PETRONAS)

Temaris is comprised of two gas discoveries in shallow water (~70 metres) offshore Peninsular Malaysia on the western flank of the Malay basin and covers an area of around 1,200 sq km.

The main discovery, Tembakau, was originally made in 2012 and appraised in 2014 while the smaller Mengkuang discovery was made in 2015, both by Lundin Malaysia B.V. (now International Petroleum Corporation).

Tembakau is located near to infrastructure and benefits from an extensive dataset including full 3D seismic coverage, well logs, DSTs and extensive well core. Temaris’ three main stacked reservoirs comprise of Early-Mid Miocene channel sandstones which are clearly imaged on 3D seismic and which exhibit a strong amplitude response. The field has excellent reservoir properties, contains dry gas with very low levels of impurities and tested at substantial flow rates. The field is located near infrastructure, with the closest producing gas field being located 47 km away from the field.

Mengkuang is located 30 km to the northeast of Tembakau in high quality Miocene sandstones which also demonstrate strong amplitude responses. The field also benefits from a good dataset though was not tested at the time of discovery.
Previous public disclosures indicated that the existing discoveries on the Temaris Cluster could contain in excess of 250 bcf (~42 mmboe) of recoverable resources viewed as crucial to boost gas supply to Peninsular Malaysia, which is forecasted to be deficient in the next few years. The continuation of the Tembakau and Mengkuang channel sandstone reservoirs across the Temaris PSC also represents significant exploration upside. Seascape has been using high-end geophysical techniques to identify these channelised targets and is confident additional
Similar to the Company’s DEWA Complex Cluster (Seascape, 28%) development asset, the Temaris Cluster development will fall under the Small Field Asset (“SFA”) terms which are specifically designed to simplify and incentivise rapid development of smaller hydrocarbon accumulations in Malaysia and provide enhanced field economics versus traditional PSCs.
Given the shallow water depths and nearby infrastructure, Seascape is targeting a low-cost development plan utilising a normally unmanned platform with minimal processing which could support a potential gross production plateau of up to 100 mmscfd.
The key terms of the Award are to deliver a Field Development and Abandonment Plan within 18 months along with certain specialised subsurface studies and 3D seismic reprocessing. The financial commitment under the Award is ~US$2 million and will be met through Seascape’s existing cash resources.
