Monumental Energy Reports Initial Flush Production of 3000 Barrels and a Stable Unstimulated Flow Rate of 300 Barrels a Day at Ngaere-2

Monumental Energy Corp. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce a better-than-anticipated, stable, unstimulated flow rate of 300 barrels a day from the Ngaere-2 well located within a 4km radius of all the other online production wells and near the Waihapa production facility. Currently the company has four wells online: Copper Moki-1, Ngaere 1 and 2 and Waihapa H1. Six additional wells are in the pipeline and permitted. Monumental Energy along with NZEC as operator and its co-venturer L and M have estimated that 1000 boe/d is possible. Constrained production is choked back to maintain stable flow and additional ways to increase daily production and capacity are underway immediately.

Maximilian Sali, Chief Executive Officer comments: “The success of the last three wells has exceeded our expectations, and with a stronger than forecast oil price, this has created the perfect storm to grow the company and be able to continue additional workovers. Another six activities are currently in the pipeline along with new applications to drill fresh oil and gas wells.”

Monumental and New Zealand Energy Corp. (“NZEC”) entered into a funding agreement (see news releases dated January 12, 2026, March 5, 2026, and March 10, 2026), enabling Monumental to participate in mutually agreed appraisal and development workover projects aimed at increasing production across Petroleum Mining Licences PML 38140 and PML 38141 (the “Licences”). The Waihapa H1 well is the latest successful project executed under this agreement. NZEC holds a 50% interest in the Licences, which are located in the onshore Taranaki Basin, New Zealand.

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. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce a better-than-anticipated, stable, unstimulated flow rate of 568 barrels per day of 38° API crude oil from the reworking of the Waihapa H1 well in New Zealand’s prolific onshore Taranaki Basin. The well was successfully brought back online using a low-cost perforation program across seven intervals, totaling six-metres and is located within 100-metres of existing production infrastructure (see the Company’s news release dated March 16, 2026). To note: the daily flow rate continues to rise on a daily basis and we will update the market with total production at the end of the month.

Monumental and New Zealand Energy Corp. (“NZEC”) entered into a funding agreement (see news releases dated January 12, 2026, March 5, 2026, and March 10, 2026), enabling Monumental to participate in mutually agreed appraisal and development workover projects aimed at increasing production across Petroleum Mining Licences PML 38140 and PML 38141 (the “Licences”). The Waihapa H1 well is the latest successful project executed under this partnership. NZEC holds a 50% interest in the Licences, which are located in the onshore Taranaki Basin, New Zealand.

Maximilian Sali, Chief Executive Officer, comments: “This workover has significantly exceeded expectations and reinforces our focus on capital-efficient production growth. I would like to thank our operator, New Zealand Energy Corp., and our lead technical director, Bill Treuren, for their expertise in successfully executing these workovers, along with our partner L&M Energy Ltd., which holds the remaining 50% interest in the Licences. With strong results from both Waihapa H1 and the previously announced Ngaere 1 well, we are seeing clear repeatability in our approach and are excited to advance a growing pipeline of permitted wells.”

The results from the New Zealand workover programs highlight the potential for imminent production revenue, which further validates Monumental’s strategy of targeting low-risk, high-impact opportunities capable of delivering cash flow with minimal capital investment.

MONUMENTAL ENERGY ANNOUNCES COMMERCIAL PRODUCTION AT WAIHAPA H1

ALL 7 PERFORATIONS ACHIEVED SIGNIFICANT OIL PRODUCTION AND ASSOCIATED GAS

Monumental Energy Corp. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce the successful restart of commercial production from all 7 perforations in the Mount Messenger formation located near the top of the Waihapa H1 well. The Waihapa H1 well is located within 100 meters of the Waihapa production facility and oil is being sent through the pipeline into a holding tank at the facility.

Monumental and New Zealand Energy Corp.(“NZEC”) entered into a funding agreement (see the Company’s news releases dated January 12, 2026, March 5, 2026 and March 10, 2026), which enables Monumental to participate in mutually agreed-upon appraisal and development workover projects with NZEC and aimed at increasing oil and gas production from the area covered by Petroleum Mining Licences PML 38140 and PML 38141 (together, the “Licences”). The Waihapa H1 well is another project the parties have chosen under the funding agreement.  NZEC holds a 50% interest in the Licences, both being located in the onshore Taranaki Basin, New Zealand.

ABOUT WAIHAPA H1

Waihapa H1 was drilled in 2008 and produced oil from the lower Tikorangi formation at rates above 1500 barrels a day.  The NZEC and Monumental exploration team have identified 60 meters of prospective “bypass pay” in the Mount Messenger formation above the Tikorangi formation, which is the same zone that was perforated at Ngaere-1 (see the Company’s March 5, 2026 news release).

Seven 6-meter perforations all encountered natural, high pressured oil flow with no additional stimulation besides a perforation gun.  Oil production started when the first perforated areas came on line as of Friday, March 13, 2026. Monumental expects to publish the stabilized flow rate and total production of oil and gas once testing has been completed and the data assessed.

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.

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 USD$10 to USD$15 per MCF, making it one of the highest gas price environments.

Maximilian Sali, Chief Executive Officer, comments “The well was perforated during daylight hours over 5 days and in the evenings the well was flowed to clear perforation debris and to understand if each perforated zone added flow capacity and ultimately reserves. Interestingly, each day the well flowed better and all seven perforations performed better than expected. We are not currently able to announce a stable flow rate as we do not have enough capacity on site and tanker trucks to be able to handle the volume. Currently three tanker trucks are going back and forth from Waihapa H1 to the port in New Plymouth. Gas is also being processed to the tune of roughly 1 TJ of gas which is sold immediately to market.  I would like to note that New Zealand has high gas prices and the current price of Brent crude is above $100 USD per barrel.”

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. Bottom of Form

MONUMENTAL ENERGY ANNOUNCES SUCCESSFUL INITIAL PRODUCTION FROM NGAERE-1 WELL AND PROVIDES OUTLOOK FOR 2026

Monumental Energy Corp. (“Monumental” or the “Company”) (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce (further to the Company’s news release dated January 13, 2026) the successful perforation and strong initial production results from the Ngaere-1 well, in partnership with New Zealand Energy Corp. (“NZEC”) and L&M Energy Ltd. (“LME”) (collectively, the “Partnership”). NZEC is the holder of a 50% interest in the Petroleum Mining Licences PML 38140 and PML 38141 (together, the “Licences”) located in onshore Taranaki, New Zealand, pursuant to a joint operating agreement between NZEC and L&M Energy Limited (the “JOA”). 

The Partnership enables Monumental to participate in certain mutually agreed upon appraisal and development workover projects with NZEC to increase oil and gas production from the area covered by the Licenses. The parties have selected Ngaere-1 well as the first project under the Partnership. 

NGAERE-1

The Ngaere-1 well was successfully perforated into a previously untested “bypass pay zone” less than two weeks ago under the recently executed funding and gainshare agreement between the Partnership (see the Company’s news release dated January 13, 2026 and NZEC’s news release dated February 4, 2026).

Following perforation, the well immediately flowed oil and gas, producing 580 barrels of crude oil within the first six hours of operation. Production was temporarily shut-in to allow additional tanker capacity to arrive on site to transport the crude for delivery to port and subsequent refining.

Since recommencing operations, the Ngaere-1 workover well has produced approximately 3,000 barrels of crude oil to date, currently stabilizing at approximately 120 barrels of oil per day, without the benefit of additional stimulation and optimization activities which are planned for a future date.

For context, Brent crude oil prices are currently above US$85 per barrel, with New Zealand crude typically achieving only a modest discount to Brent pricing. Operating costs in New Zealand are primarily denominated in New Zealand dollars (currently approximately US$1 = NZ$1.68).

Although the Ngaere-1 well was originally drilled more than 30 years ago, the upper zone that is now producing was not previously evaluated, resulting in limited historical log data for this interval. Despite this uncertainty, the well flowed oil and gas immediately upon perforation, and initial production revenues have already recovered the workover costs within the first weeks of operation.

The next phase of work will focus on continued production and reservoir evaluation while preparing for a recompletion program designed to increase drawdown on the reservoir, which is expected to further enhance production rates and ultimate recoverable reserves.

The Partnership considers the initial results highly encouraging given the historical log uncertainty and believes they demonstrate the potential for similar opportunities across the field.

WAIHAPA H1 AND NGAERE-2 

Following the strong initial results from the cost-effective perforation of the Mount Messenger Formation at the Ngaere-1 well, the Partnership has agreed to immediately advance similar perforation operations at the Waihapa H1 and Ngaere-2 wells.

These perforations are expected to take place as soon as operational logistics permit and will target the same formation that has demonstrated encouraging early production at Ngaere-1.

The Company’s management believes these additional perforations represent a low-cost, high-impact opportunity to unlock previously bypassed hydrocarbon zones within existing wells. Success at these locations could further validate the broader potential of the Mount Messenger Formation across the permit area and provide additional near-term production growth.

OUTLOOK FOR 2026 

Monumental has also led and co-funded an application to extend the Ngaere permit area by approximately 4050 acres, funding 50% of the application costs.

The proposed extension area lies between the Cheal oil field and the Ngaere wells currently under evaluation within the Ngaere field. Seismic data indicates the potential for additional hydrocarbon accumulations within this corridor, particularly at shallower depths similar to those currently being evaluated. The application has been posted on the New Zealand regulator’s website and is currently under review. As part of the review process, the regulator will consider geological and production evidence supporting the potential extension of the Ngaere field into the proposed acreage.

In addition, Monumental is actively pursuing further onshore permit applications within the Taranaki Basin with the objective of establishing a longer-term position focused primarily on natural gas development. Two additional permit areas are currently under submission with the regulator.

The Company believes that onshore Taranaki represents the most promising region in New Zealand capable of addressing the country’s growing natural gas supply shortage. Monumental is therefore actively pursuing opportunities in this region with the goal of supporting both near-term gas supply and longer-term energy development.

GOVERNMENT FUNDING 

On January 12, 2026, the Government of New Zealand announced the opening of its Energy Development Fund, which is designed to support new natural gas exploration and development projects within the country.

Monumental Energy is currently evaluating several opportunities within its portfolio that its technical team believes may qualify for funding under this program. The Company believes that participation in this initiative could help accelerate the development of domestic gas resources and support New Zealand’s efforts to address growing energy supply constraints.
