MONUMENTAL ENERGY REPORTS INITIAL FLUSH PRODUCTION OF 3,000 BARRELS AND A STABLE UNSTIMULATED FLOW RATE OF 568 BARRELS PER DAY FROM WAIHAPA H1

Monumental Energy Corp. has announced impressive production results from the reworked Waihapa H1 well in New Zealand's onshore Taranaki Basin, reporting an initial flush production of 3,000 barrels and a stable unstimulated flow rate of 568 barrels per day of 38° API crude oil. The company notes that the daily flow rate continues to rise, suggesting potential for even stronger performance. The well was successfully brought back online through a cost-effective perforation program across seven intervals totaling six meters, with the added advantage of being located within 100 meters of existing production infrastructure.

The success builds on Monumental's partnership with New Zealand Energy Corp. (NZEC), which holds a 50% interest in Petroleum Mining Licences PML 38140 and PML 38141, with L&M Energy Ltd. holding the remaining 50%. This workover represents the latest successful project under their funding agreement that enables participation in mutually agreed appraisal and development projects aimed at increasing production across the licenses. The results follow the previously announced success at the Ngaere 1 well, demonstrating what CEO Maximilian Sali describes as "clear repeatability" in their approach.

The production results significantly exceeded management expectations and validate Monumental's strategic focus on capital-efficient production growth through low-risk, high-impact opportunities. The company's approach targets near-term cash flow generation with minimal capital investment, positioning it well for revenue generation in the current market environment. With a growing pipeline of permitted wells and proven workover techniques, Monumental appears well-positioned to continue expanding production across its New Zealand assets.

Beyond its New Zealand oil and gas operations, Monumental maintains diversified exposure to the energy transition through a 2% net smelter return royalty on Summit Nanotech's interest in the Salar de Turi lithium project in Chile. This combination of conventional energy production and critical minerals exposure positions the company to benefit from both current energy markets and the evolving clean energy landscape.
