• Brookside secures more than 40% of initial strategic leasehold objective for Riverbend AOI
• Advancing title, regulatory and development planning to support future reserve-definition activity
• Evaluating additional prospective acreage within the broader Riverbend fairway

Brookside Energy Limited (ASX: BRK) is pleased to provide shareholders with an update on the progress made at its Riverbend Area of Interest (Riverbend AOI) in the Anadarko Basin, Oklahoma. Since first announcing Riverbend, Brookside has advanced the opportunity from initial technical identification and early-stage leasing into a structured land, title and development planning program designed to support a future operated development pathway. Riverbend represents an additional growth opportunity within Brookside's Anadarko Basin portfolio, with the potential to expand the Company's operated footprint beyond its existing SWISH position and add scale, future reserve growth and additional undeveloped drilling inventory. Brookside's current Riverbend work program is focused on three key objectives: continuing disciplined leasehold capture across priority areas within the Riverbend AOI; advancing title, regulatory and development planning to support future reserve-definition activity; and evaluating additional prospective acreage within the broader Riverbend fairway through ongoing technical and land analysis. Brookside has now secured more than 40% of its initial strategic leasehold objective for the current phase of Riverbend acreage capture. In parallel with leasing, Brookside continues to advance title review, technical analysis and regulatory planning across the Riverbend AOI. Brookside is also evaluating prospective acreage within the broader Riverbend fairway to assess whether the initial Riverbend development concept can be expanded across additional areas. Subject to successful acreage consolidation, regulatory approvals and initial reserve-definition drilling, Riverbend has the potential to add material scale to Brookside's Anadarko Basin position and strengthen the Company's inventory of undeveloped drilling locations.

Riverbend remains in the land, title and regulatory planning phase. Initial reserve-definition drilling remains subject to further acreage consolidation, title completion, regulatory approvals, permitting, service availability, commodity prices and Brookside's capital allocation priorities.
