• 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.”

• 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.
