Lion One Provides Strategic Operational Update for March 2026

North Vancouver, British Columbia--(Newsfile Corp. - April 9, 2026) - Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) ("Lion One" or the "Company") provides a strategic operational update for its 100% owned Tuvatu Gold Mine in Fiji for March 2026.

"Tuvatu is a high-grade asset with significant potential, and our focus now is on translating that potential into consistent, repeatable performance," stated Campbell Olsen, CEO of Lion One Metals. "Over the coming months, our efforts will be firmly directed toward reliability, discipline, and execution across the operation as we strengthen equipment and power reliability, advance our development pipeline, and position Tuvatu for sustainable long-term production."

Operational Overview

During March, the Tuvatu mine delivered:

• Average mill feed grade of approximately 4.97 g/t Au versus a budget of 4.65 g/t Au.

• Gold production trending toward plan, with Week 12 ounces recovered at 306 oz versus 308 oz budgeted.

• Development performance improving into month-end, with total development in Week 12 at 102% of plan and jumbo development at 135% of plan.

These results were achieved while the operation continued to experience lower-than-planned throughput due to equipment availability and power reliability constraints.

Reliability and Infrastructure

Improving asset reliability and site power stability is a central focus for 2026. Key initiatives underway include:

• Commissioning of new Yantai boggers and ordering critical parts for multiple loaders to support higher stoping tonnes.

• Refurbishment strategy for the generator fleet, including returning Generator 7 from New Zealand and a condition assessment of the remaining units to underpin a revised power strategy.

• Ongoing upgrades to the site HV network and a metering replacement at the Waimilika solar installation, which is expected to improve grid power performance and solar savings once completed.

The Company has reintroduced an Approval for Expenditure (AFE) process to prioritise capital and maintenance spending on these reliability workstreams.

Growth and Project Pipeline

Lion One is advancing a suite of projects designed to support medium-term growth and operating resilience at Tuvatu:

• Tailings Storage Facility Stage 2B: Contractor selected; a contract in the order of $6.5 million (VEP) is targeted for execution in April 2026 to enable mobilisation ahead of the dry season.

• Flotation circuit: Building permit drawings have been lodged with Nadi Town Council, structural works are progressing, and detonator magazine expansion is nearing completion.

• Evaporation system: A Limited Purchase Order has been issued to MineTek and detailed design is underway.

• Site facilities: Planning continues for changeroom expansion, a new surface sub-station for the west zone portal, additional workshops, vehicle parking, and a mine inventory warehouse.

On the geology front, infill and resource growth drilling continued on the UR2 and URA vein systems, with four underground rigs operating and a fifth surface rig added in Week 11. The western decline reached the URA vein system and ore development has commenced, opening an additional production front.

Near-term Priorities

For the coming quarter, Lion One's strategic operating priorities at Tuvatu are to:

• Stabilise and improve underground equipment availability, especially loaders and long-hole drills, to increase stoping contribution to mill feed.

• Strengthen power reliability through implementation of the generator refurbishment plan, HV network upgrades and EFL engagement, alongside optimisation of the Waimilika solar installation.

• Deliver the TSF Stage 2B, flotation circuit and evaporation projects on schedule to support production, compliance and future expansion.

• Advance development and stoping in the 1068 and 1066 levels and the URA area to build multiple high-grade feed sources.
