Largo Provides Update on its Operational

Turnaround Progress; Delivers Improved

May Production

TORONTO--(BUSINESS WIRE)--June 25, 2025--Largo Inc. ("Largo" or the "Company")

(TSX: LGO) (NASDAQ: LGO) is pleased to provide an update on the progress of the

operational turnaround plans (see press release dated March 28, 2025), highlighted by increased

production rates for both vanadium pentoxide (“V₂O₅”) and ilmenite concentrate in May 2025.

As part of a continued focus on stabilizing and enhancing operational performance at its Maracás

Menchen Mine, the Company reports that V₂O₅ production in May 2025 was 835 tonnes,

representing a 75% increase compared to April 2025 production of 401 tonnes. Ilmenite

concentrate production for May 2025 was 3,025 tonnes, representing a 65% increase compared

to April 2025 production of 1,833 tonnes. These improvements continue to highlight the

effectiveness of measures implemented under the operational turnaround plans previously

announced.

The following initiatives contributed to improved production performance during the month of

May 2025:

 Access to the 200-level area of disseminated ore was achieved, contributing significantly

to increased mine production volumes

 Additional ore feed was sourced from the 110 and 120 levels at the bottom of the mine,

supporting higher throughput rates

 Production drilling activities met monthly targets, and drilling progress remains on track

for June

The Company continues to focus on optimizing its resource recovery and has commenced the

reprocessing of its existing non-magnetic tailings ponds to extract both vanadium and ilmenite.

These tailings, initially reprocessed solely for ilmenite feedstock, are now being evaluated for

vanadium content, supporting dual-recovery streams. Additionally, the Company plans to

enhance the existing vanadium recovery process of its iron-rich calcines and silica cake residues

to extract additional vanadium, which would be reprocessed into V₂O₅. In addition to driving

operational efficiency at its Maracás Menchen Mine, these efforts are expected to strengthen the

Company’s efforts in sustainable mining practices by reducing waste material and recovering

value from existing tailings.

The Company’s outlook for June 2025 remains positive, with production currently trending

above forecast at the time of this release. The Company expects to achieve its production

guidance range of 9,500 to 11,500 tonnes of V₂O₅ for 2025.

Daniel Tellechea, Interim CEO of Largo stated: "We are encouraged by the improved production

results achieved in May, which represent an important step forward in our operational

turnaround. The progress made to date, particularly the increased access to key mining areas

and enhanced plant stability, suggests that May may represent an inflection point for our

operational turnaround progress. While there is more work to be done, we expect a more

consistent production profile going forward as we continue executing our plan and monitoring

performance closely.”

Corporate Update

On June 9, 2025, the Company received a default notice from a counterparty for failure to deliver

900 tonnes of V₂O₅ at the scheduled time (see press release dated October 21, 2024). The same

counterparty has also alleged that some of the V₂O₅ delivered previously has failed to meet the

agreed upon specifications. The Company is currently reviewing the notice and assessing its

available options. An update will be provided as further disclosure becomes appropriate or

required.
