Brookside Energy Ltd reported its Q1 2026 results, highlighting several key achievements. The company released its independently certified year-end 2025 reserves report, confirming Total Proved plus Probable (2P) Net Reserves of 12.52 MMBOE as at 31 December 2025. This reflected continued growth in the company's reserve base, with Proved Developed Producing (PDP) reserves increasing by approximately 5% to 2.80 MMBOE and Total Proved (1P) reserves increasing by approximately 7% to 5.33 MMBOE. The reserves update delivered a reserve replacement ratio of 122%. Brookside also commenced site operations at the Suttles pad in the SWISH Area of Interest (AOI), marking the start of the company's next phase of development. The Suttles pad will host two wells, the Sabres Well targeting the Sycamore Formation and the Whalers Well targeting the Woodford Formation, each with approximately 1.5-mile lateral sections. The company closed the quarter with A$14.54 million in cash, up from A$11.82 million at the start of the quarter, and retains full access to its undrawn US$25 million credit facility, providing ample funding for the upcoming Suttles two-well development program.

Brookside's 2026 reserves report shows the company increased its Proved Developed Producing (PDP) reserves by approximately 5% to 2.80 MMBOE and its Total Proved (1P) reserves by approximately 7% to 5.33 MMBOE as of 31 December 2025.

Brookside is well positioned to convert its current balance sheet strength into the next phase of production growth as it commences operations at the Suttles two-well pad, with drilling scheduled to begin in May 2026.
