Monumental Energy to Partner on the Maata Oil Field Located Onshore in the Taranaki Region Near Two Production Facilities

VANCOUVER, British Columbia — Monumental Energy Corp. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce that it intends to acquire an ownership stake in the onshore Maata oil field with a consortium of companies including Jetex Energy Limited (the operator), New Zealand Energy Corp. (“NZEC”) and 3TCF Limited, in the onshore Taranaki Basin, New Zealand.

The nearby Copper Moki wells have already produced over a million barrels of oil, the Arakamu-2 well has an untested live oil column, and three re-perforations of existing wells in this interval in the Waihapa/Ngaere area immediately north of Maata (in all three of which Monumental participated) were oil flow successes, with initial production tests at rates of several hundred barrels per day of high value light, sweet oil. Maata-1 offers the potential to establish a new field with reserve potential in excess of 10 million barrels of oil from the Mount Messenger formation alone plus a considerable amount of associated gas. Other formations will be tested following and could potentially add millions of additional barrels. The adjacent Cheal field next door has produced over 15 million barrels. The specific Maata Prospect has not produced oil or gas and is subject to further technical work including drilling. Oil and gas hosted on nearby properties is not necessarily indicative of the oil and gas that may be hosted on the Maata Prospect. A Maata-1 drill site has now been secured, drilling inventory including casing and wellhead are being secured and regulatory drilling consents are in hand. It is anticipated that drilling will commence during the first quarter 2027, subject to the parties entering into a joint-venture and operating agreement and obtaining the applicable government approvals. In the event of discovering both oil and gas, successful production can then be readily linked into the nearby Waihapa Production Station and from there to market via existing oil and gas pipelines.

: “The plan to participate in the Maata oil field represents a significant step in building Monumental’ s assets in an incredibly profitable oil market that appears to have longevity with Brent crude forecast to remain above $100 USD well into 2027. The location and proximity to facilities for oil separation is within a few kilometres. We will provide further update when the Maata oil field transaction is completed in the very near future.”

Prior to owning and operating the Maata oil field license, these four (4) parties will need to finalize a joint-venture and operating agreement, determine ownership percentages and capital requirements, obtain any required TSX Venture Exchange approvals, and obtain any additional New Zealand government regulatory approvals. Currently, the parties are waiting for the New Zealand Petroleum and Minerals governing body to review and approve the updated operating permit for the Maata oil field license from Jetex Energy Limited.

Monumental Energy’s lead technical director, Bill Treuren, and an associate have recently completed a final due diligence trip to the chemical facility in San Antonio, Texas, where demonstrations were completed along with a tour of the facility and the equipment needed to produce this product. Following the approval of an initial budget which is $30,000 USD + freight, the equipment will be shipped to New Zealand and arrive on site within the month and provisional approval for import has already been received. The final product will be blended in the Taranaki region and in close proximity to all of the current producing, additional work over and fresh wells. This product can be used across the entire basin to potentially solve the wax issue on a commercial scale and will be monetized by Monumental and known as an “Organic Crude Oil Stabilizer”. This product will allow for better flow rates, smoother oil flow and maintain its light characteristics even at lower temperatures.

NZEC and Monumental are also a participating in an application to extend the Ngaere Mining License (PML 38141) westwards to incorporate the Beaconsfield Prospect. This application is expected to be filed imminently. This field is tied to productive zones in existing Ngaere wells, and ongoing work in the Wahapa/Ngaere Field Redevelopment Program is expected to lead to additional wells with similar characteristics in the same formations in extremely close proximity.

Monumental Energy Corp. is an exploration company focused on the acquisition, exploration, and development of oil and gas properties in New Zealand’s onshore and offshore Taranaki Basin, with current oil production, potential additional near-term oil and longer term natural gas production and natural gas development investment.

The Company has a funding agreement with New Zealand Energy Corp. (“NZEC”) targeting production optimization and workover opportunities across existing fields. The Company also holds securities of NZEC and a call option and royalty interest on multiple producing and near term producing onshore wells with NZEC.
