• Process plant – structural, mechanical, piping and electrical installation (“SMPEI”) is approximately 50% complete. The grinding building is structurally complete and the ball mill has been installed in its final location within the building. Additionally, the SAG mill is ready to be lifted into its final position.
• CIL and Detox – CIL tank ring fit-out has advanced to 53 of 60 rings (88% complete), with leach tanks approximately 80% complete and detox tanks approximately 70% complete; all CIL and detox agitators are fully assembled.
• Civil works – bulk earthworks are 93% complete and civil foundations are 92% complete; pre-stripping of the open pit has advanced to 71% complete.
• Site infrastructure – the mine office and heavy mobile equipment (“HME”) office are complete and in use; the water treatment plant is complete; camp installation is approximately 90% complete (kitchen building outstanding, due on site in September 2026); industrial buildings are approximately 88% complete; and the explosives magazine is complete and awaiting its operating permit.
• Tailings Storage Facility (“TSF”) – TSF construction is approximately 60% complete.
• Power – the 2 megawatt (“MW”) grid connection to ENATREL, Nicaragua’s national electricity transmission company, has been completed and energised, being available for operations and commissioning, with the 800 kilovolt-amperes (“kVA”) back-up generator connected and available for operation; the main substation remains targeted for completion in December 2026.
• Mining fleet – 10 Caterpillar Inc. (“CAT”) 777 haul trucks and two CAT 6020 excavators are on site and operational, with a further five haul trucks, a third excavator, two wheel loaders, a telehandler and a second bulldozer in transit or in manufacture.
• ROM stockpile – approximately 244,000 tonnes (“t”) of ore is stockpiled on the run-of-mine (“ROM”) pad ahead of commissioning.
• Logistics – the Company has experienced some delivery delays to certain imported equipment and materials as a result of wider disruption to international shipping linked to the conflict in Iran. The Company is evaluating alternative logistics solutions to mitigate the impact on construction.
• Runruno – Gold production from Runruno is forecast to be at the upper end of the 2026 production guidance of 40,000 - 48,000 ounces, owing to the mining of higher-grade ore at Stage 5 pit. The mining of higher-grade ore is expected for the remainder of 2026.

Darren Bowden, CEO of Metals Exploration, commented:

“Construction at La India continues to make strong progress, with installation of the process plant advancing across multiple fronts. The ball mill is in its final position, the SAG mill is ready to follow, and the CIL tank fit-out is nearing completion. Alongside this physical progress, we have also successfully completed a US$27 million debt facility with Banco de America Central S.A, a local Nicaraguan bank and received an initial drawdown of over US$20 million, reimbursing the majority of the equipment capital committed from our own resources to date and significantly strengthening the Company’s cash position.

“Our owner-operator mining fleet also continues to expand, with 10 haul trucks and two excavators already on site. Whilst we are managing some logistics disruption affecting certain imported items, linked to the wider impact of the conflict in Iran on international shipping, we continue to work closely with our suppliers to keep deliveries on track.

“These milestones demonstrate the continued momentum at La India as we advance towards first gold, and we look forward to updating shareholders as construction progresses.”

Finance

The Company, via its wholly-owned subsidiary, La India Gold, S.A. ("La India Gold"), has successfully secured, and drawn down upon, an equipment financing package for its CAT mining fleet from Banco de America Central S.A. (“BACS”), a Nicaragua located bank.

Key terms of the BACS facility are as follows:

• Facility size: US$27.0 million.
• Purpose: to finance the Company’s initial La India mining fleet.
• Term: 5 years (60 months) maturing 17 August 2031.
• Repayment profile: a 12-month grace period on principal (interest only paid monthly), followed by 48 equal monthly instalments of principal plus interest.
• Pricing: variable rate of 6-month Term SOFR plus a margin of 3.15% per annum, reset quarterly; initial rate of 7.00% per annum, with a minimum (floor) rate of 6.85% per annum for the life of the loan.
• Security: first-ranking security over La India Gold's CAT mining fleet, together with the corporate guarantee from Metals Exploration.
• Covenants: customary financial covenants for a loan of this type.

The US$6.8 million loan balance will be drawn down as further equipment arrives in Nicaragua. To date, the Company has paid US$30.5 million for the CAT mining fleet with a final US$0.7 million due next month. The investment in the Company’s CAT mining fleet is not included in the Company’s La India Project development and construction budget.
