Monumental Energy Announces Commencement of Copper Moki Workovers in New Zealand

Monumental Energy Corp. ("Monumental" or the "Company") (TSX-V: MNRG; FSE: ZA6; OTCQB: MNMRF) is pleased to announce that workover operations have commenced at the Copper Moki-1 and Copper Moki-2 wells, located in the Taranaki Basin, New Zealand.

The workover program being carried out in conjunction with the Company's partner, New Zealand Energy Corp., involves re-entering both wells to perform downhole cleanouts, replace tubing and rods, and perforate the Mt. Messenger formation. The objective is to restore production from the Mt. Messenger sands and resolve known flow restrictions identified in previous operations.

Additionally, the wells have never undergone a full tubing replacement or sand cleanout, providing Monumental with the opportunity to perforate an unproduced zone. Having remained idle for 18 months, the wells also present potential for a significant flush production increase, further enhanced by the planned perforation of an additional 5-metre interval in the Mt. Messenger formation.

Copper Moki-1 Workover Highlights:

• The well, drilled to a depth of 2,220-metres with 7" casing set at 2,214-metres, will be re-entered to retrieve approximately 600-metres of parted sucker rods and remove wax and sand buildup.
• A 5-metre interval of the Mt. Messenger formation, located at approximately 1,587 metres, will be perforated to access untapped hydrocarbon zones.
• New tubing, a tubing anchor, and a complete pump string will be installed to optimize production efficiency.
• The well will be fully equipped with a pump and rod system, after which flow testing will be conducted in preparation for a return to production.

Copper Moki-2 Workover Highlights:

• The 2,084-metre well will undergo similar operations to Copper Moki-1, including a full tubing replacement and comprehensive well cleanout.
• A new pump and rod system will be installed to enable production from the newly perforated zone.
• As with Copper Moki-1, well pressure is several hundred psi below hydrostatic, suggesting favourable conditions for drawdown and early production.

Max Sali, Vice President of Corporate Development and Director, commented: "These workovers represent a meaningful step toward monetizing the Taranaki Basin assets. With infrastructure in place, we are well-positioned to restore production and potentially generate early cash flow to support Monumental's broader strategic objectives. We are also pleased to have a newly upgraded rig on site, which is now fully operational and will enable the expedited execution of future projects."

Field operations are expected to be completed in the coming weeks, with initial production results anticipated shortly thereafter. To date, the program remains under budget; Monumental does not anticipate any further expenditures until the workover is complete and flush production begins. Total spending to date is approximately NZD $560,000 (CAD $460,000).
