Pumps Will Be Turned up to Maximum Capacity to Test Favourable Flush Production

VANCOUVER, British Columbia--(BUSINESS WIRE)--Jul. 21, 2025-- 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 both the Copper Moki-1 and Copper Moki-2 wells, located in the prolific Taranaki Basin, New Zealand.

Taranaki Basin, New Zealand: Copper Moki-1 and 2 Producing

Following completion of the strategic workovers, both wells are now online and producing at stable rates—100 barrels of oil per day (bopd) from CM-1 and 75 bopd from CM-2, and with rates continuing to increase on a daily basis. The new pump systems are designed for long-term performance and provide the flexibility to increase output further during flush production and future ramp-up period. As the pumps are performing as anticipated, both will be turned up to produce above the rated pump to test maximum capacity.

Note that flush production from both wells combined could be more than 300 bopd, as it was previously as high as 300 bopd after the last pump replacement at Copper Moki-2 alone at the time of the original drilling program at Copper Moki a few years ago.

Multiple Revenue Catalysts Unlocked:

• High-Margin Gas Monetization: The gas produced at Copper Moki is now tied into regional infrastructure, allowing Monumental to capitalize on New Zealand gas prices of US$15–20 per MMBtu—among the highest globally. Gas production numbers will be released in the coming weeks.
• Royalty Revenue: Monumental earns a 25% royalty on all oil and gas sales after the recovery of initial capital (at 75% of net revenue payback rate)¹.
• Immediate Cash Flow Potential: With both wells operating, the Company anticipates near-term, high-margin cash flow from Copper Moki with no further capital deployment required and the royalty structure to be in effect (as noted above). Operating rates and numbers will be known in the coming weeks and months.

Cumulative flush production data—including barrels of oil (BBL), barrels of oil equivalent (BOE), and associated gas volumes—will be reported in the coming weeks.

Max Sali, VP Corporate Development and Director comments: “The successful restart of Copper Moki reinforces the strategic value of our pivot into oil and gas—particularly given today’s strong commodity prices. It’s a move that not only strengthens our near-term revenue profile but also positions us to pursue additional high-impact opportunities with our trusted partners at New Zealand Energy.”
