MONUMENTAL ENERGY ANNOUNCES PERFORATIONS HAVE COMMENCED AT THE WAIHAPA H1 WELL

Monumental Energy Corp. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce the mobilization of the operations crew from the Ngaere-1 well to the Waihapa H1 well, located only a few kilometres away, in partnership with New Zealand Energy Corp. (“NZEC”) and L&M Energy Ltd. (“LME”) (collectively, the “Partnership”) (see the Company’s news releases dated January 13, 2026 and March 5, 2026). NZEC holds a 50% interest in Petroleum Mining Licences PML 38140 and PML 38141 (together, the “Licences”) located in the onshore Taranaki Basin, New Zealand, pursuant to a joint operating agreement between NZEC and LME. The Partnership enables Monumental to participate in mutually agreed-upon appraisal and development workover projects with NZEC aimed at increasing oil and gas production from the area covered by the Licences. The parties have selected the Waihapa H1 well as the next project under the Partnership. ABOUT WAIHAPA H1 Waihapa H1 was drilled in 2008 and produced significant oil rates from the lower Tikorangi formation at significant rates above 1500 barrels a day and is still a small producing well since no additional work has been done to restimulate.  The NZEC and Monumental exploration team have identified 60 meters of prospective “bypass pay” in the Mount Messenger formation, which is the same zone that was perforated at Ngaere-1 (March 5, 2026 news release). Seven 6-meter perforations will occur over the course of this week and flow testing will begin immediately. Numbers will be released to the market after an appropriate flow test has been completed. The Mount Messenger formation is the primary zone in the highly successful adjacent Cheal oil field which has produced roughly 12 million barrels of oil from a relatively small area size. Due to the success at Ngaere 1, it has been decided to perforate the H1 well over an extended zone and Monumental is optimistic that oil and gas will be successfully flowed. The Waihapa H1 well is located within sight of the Waihapa production facility, allowing associated gas to be connected directly to the facility for immediate processing and production. Current natural gas prices in New Zealand range from approximately US$10 to US$15 per MCF, making it one of the highest gas price environments globally. IMMEDIATE PROGRAM AND TIMING Following the strong initial results from the cost-effective perforation of the Mount Messenger Formation at the Ngaere-1 well, the Partnership has moved quickly to advance similar operations at additional wells within the permit area. Operational crews have now been mobilized from Ngaere-1 to the Waihapa H1 well, where perforation operations are currently underway. These perforations are targeting the Mount Messenger Formation, the same interval that has demonstrated encouraging early production results at Ngaere-1. Upon completion of the Waihapa H1 program, the Partnership intends to proceed with similar perforation operations at the Ngaere-2 well next week given no delays. Management believes these follow-up perforation programs represent an efficient method of accessing previously bypassed hydrocarbon zones within existing wells. Success at Waihapa H1 and Ngaere-2 could further demonstrate the broader productivity of the Mount Messenger Formation across the permit area and support additional near-term production growth for the partnership. The Company will provide further updates as operations progress and production data becomes available.Top of Form MANAGEMENT CHANGE The Company also announces that Michelle DeCecco has resigned as chief executive officer (“CEO”) of the Company, effective March 9, 2026. Max Sali, who currently serves on the board of directors and as VP Corporate Development, founder and significant shareholder of the Company, has been appointed as CEO. Ms. DeCecco will remain on the board of directors. The company thanks Ms. Dececco for her role as CEO and looks forward to working closely with her as a member of the board.
