Lisbon, Portugal--(Newsfile Corp. - April 23, 2026) - Lithium Africa Corp. (TSXV: LAF) (FSE: 6MQ) ("Lithium Africa" or the "Company") is pleased to provide an exploration update on its Côte d'Ivoire assets, highlighted by the commencement of its first drill program at Adzopé since going public and continued advancement of priority targets at Agboville.

Highlights at Adzopé - Drill-Ready Target

• 2,000 m reverse circulation ("RC") drill program scheduled to commence at Adzopé in late April 2026.

• Program to test one part of the newly identified, multi-km "Saby Trend", a broad lithium-bearing corridor associated with spodumene-bearing pegmatites defined through prior auger drilling, trenching, mapping and other surface work.

• Surface trenching at Adzopé returned a significant lithium intercept of 8.0 m at 1.10% Li₂O from 31.4 m, including 5.2 m at 1.47% Li₂O and a peak interval of 1.0 m at 1.74% Li₂O, supporting the Saby Trend as a drill-ready target. Laboratory results from a second trench in the southern part of the Saby Trend are pending.

• Drone-based DTM survey completed across the broader Saby Trend, with detailed mapping and pegmatite fractionation studies to continue during drilling and elsewhere within the Adzopé license.

• Adzopé is located approximately 100 km from the Port of Abidjan and is accessible by paved road (Figure 1).

Highlights at Agboville - Emerging District Adjacent to Atlantic Lithium

• At Agboville, surface mapping and soil and rock sampling has identified spodumene-bearing pegmatites in the northeastern part of the license, while regolith mapping, regional reconnaissance and follow-up soil geochemistry continue across the broader ~400 km² land package.

• Ongoing Agboville soil and trenching programs are expected to conclude within approximately two months.

• The Company's Agboville project is located immediately adjacent to Atlantic Lithium Limited's ("Atlantic Lithium") Agboville license to the northeast, where pronounced lithium in soil anomalies and spodumene have been identified, similar to what the Company is seeing within our Agboville license.¹

• Agboville is located approximately 85 km from the Port of Abidjan and is accessible by paved road (Figure 1).

The upcoming drill program will test one part of the broader Saby Trend at Adzopé, while additional mapping, pegmatite fractionation and target refinement continue elsewhere along the trend within the Adzopé license. At the same time, ongoing regolith mapping, regional reconnaissance, soil geochemistry and trenching preparations at Agboville continue to advance additional targets, with further upside across the Company's Côte d'Ivoire portfolio from the ~368 km² Sikensi ground (Figure 1), currently under application.

Tyron Breytenbach, CEO, commented, "The start of drilling at Adzopé marks a major milestone for Lithium Africa as our first drill campaign since going public. It is an important step in executing our strategy of systematically advancing high-potential lithium assets across Africa through disciplined, value-focused exploration."

Mamadou Coulibaly, Director and Head of West Africa, commented, "The Saby Trend was identified in-house through the disciplined work of our Côte d'Ivoire team, from mapping and auger drilling to trenching and target refinement. This first drill program will test only one part of that broader trend at Adzopé, while additional work continues elsewhere within the Adzopé license and at Agboville, highlighting the wider discovery potential of our Côte d'Ivoire portfolio."

Adzopé Drill Program

The Company is preparing to commence a 2,000 m RC drill program at its Adzopé license in Côte d'Ivoire in late April 2026. The program is designed to test one segment of the Saby Trend, a broad lithium-bearing pegmatite corridor identified within the license area.

The Saby Trend has been progressively defined through prior auger drilling, trenching, surface mapping and pegmatite fractionation studies (Figure 2), all of which point to a continuous corridor of spodumene-bearing LCT pegmatites. Trench 1 at Saby Main returned 8.0 m at 1.10% Li₂O from 31.4 m, including 5.2 m at 1.47% Li₂O and a peak interval of 1.0 m at 1.74% Li₂O within weathered saprolite - grades the Company considers particularly encouraging given that lithium is typically depleted in saprolite relative to underlying fresh rock (see Appendix A for full results of Trench 1). Trench 2 (Figure 2) was excavated in Q1 2026 and visible spodumene logged in the trench is interpreted to support continuity of the Saby Trend; assay results are pending.

The upcoming RC program will test the southern part of the Saby Trend at depth, while additional geological mapping and pegmatite fractionation work continues elsewhere along the corridor within the Adzopé license.

In support of the program, Lithium Africa completed a drone-based digital terrain model ("DTM") survey across the broader Saby Trend, which was used for drill-pad siting and structural interpretation. Detailed geological mapping and pegmatite fractionation studies along the entire Saby Trend will continue in parallel with drilling, supported by regional geophysical interpretations.

The Company has selected International Drilling Company Côte d'Ivoire SASU as drilling contractor for the Adzopé program. Assay results from the program will be reported as they are received from the laboratory and validated by the Qualified Person.

Agboville Exploration Update

At Agboville (Figure 3), exploration activities continue to advance across multiple workstreams. Surface geology and regolith mapping in the northeastern corner of the license has identified spodumene-bearing pegmatites. Identified outcrops of spodumene-bearing pegmatites are on-trend with soil anomalies and spodumene float within the Atlantic Lithium Agboville license, as disclosed by Atlantic Lithium in its news releases dated May 22, 2025 (Spodumene Pegmatite Discovered in Côte d'Ivoire) and October 20, 2025 (Pronounced Lithium-in-soil Anomalies within Agboville and Rubino Licences, Côte d'Ivoire), highlighting a trend more than 5 km in strike.

Initial soil survey programs over priority areas have been completed with full results pending, and a second round of follow-up sampling is planned along the continuation of identified pegmatite trends. In addition, a trenching program targeting outcropping spodumene-bearing pegmatites has been designed and community consultation for this program has commenced.

These activities, including ongoing claim-wide reconnaissance geology and regolith mapping are expected to conclude within approximately two months, ahead of the onset of the rainy season.

Community Engagement

Lithium Africa continues to prioritize early, transparent and respectful engagement with local authorities, landowners and village representatives in support of its exploration programs in Côte d'Ivoire.

Ahead of drilling at Adzopé, the Company met with local authorities, village leaders and landowners to present the RC drill program, discuss safety and environmental protection measures, and review crop assessment and compensation procedures where required. Similar community engagement has also been undertaken at Agboville in advance of planned trenching.

The Company believes constructive community engagement is fundamental to responsible exploration and to the continued advancement of its Côte d'Ivoire portfolio.

The Company expects to provide further updates as drilling progresses at Adzopé and as field programs continue at Agboville.

QAQC
All trench (and auger) samples were collected under the supervision of the Company's employees. Samples were bagged, and blank material (cement) and certified reference materials were inserted at regular intervals at the company's field camp. Field duplicates were also included in the sample stream. Groups of samples were placed in sealed bags and submitted to Intertek Minerals in Tarkwa, Ghana, for sample preparation, after which pulps were securely transported by Intertek to Intertek Genalysis in Perth, Western Australia for analysis.

Sample preparation and analytical work for this trench program were carried out by Intertek. Samples were prepared according to Intertek method SP02, whereby samples were dried and pulverized such that 85% passed a 75-micron (200 mesh) screen.

Pulverized samples were analysed using Intertek Genalysis method 4A-Li/MS48, comprising a multi-acid digest (hydrofluoric, nitric, perchloric and hydrochloric acids) in Teflon tubes, followed by analysis by inductively coupled plasma mass spectrometry (ICP-MS). The multi-acid digest is considered a near-total digestion. Lithium hosted in certain minerals may not be completely dissolved.

Laboratory QA/QC procedures included the analysis of blanks, certified reference materials and duplicates, with results indicating acceptable levels of accuracy and precision.
