Caprock Mining Corp. (CSE: CAPR) ("Caprock" or the "Company") is pleased to announce that its technical team has discovered the presence of zinnwaldite, an extraordinary lithium-bearing mineral, during a recently concluded prospecting and sampling program on the eastern-most claim block (the "Main Claim Block") at its Ackley Lithium-Tin-Molybdenum-REEs property ("Ackley", or the "Property") located in south-eastern Newfoundland, for which the Company has an option to acquire a 100% interest.
Caprock's CEO Mr. Vishal Gupta states: "Historical work at Ackley returned assays of up to 0.91% lithium oxide, however the specific lithium-bearing mineral was never identified until an internal assessment of recently obtained samples by Caprock's technical team. We are very excited by this discovery, since we believe that it is much easier and a lot less capital-intensive to produce lithium hydroxide from zinnwaldite than from the highly sought-after mineral, spodumene."
Mr. Gupta goes on to say, "Zinnwaldite is being successfully mined and processed at the Zinnwald Lithium project in Germany, and its presence has only been documented a handful of times in Canada, previously. While it is still early days in our exploration work at Ackley, initial prospecting work indicates a potential for extensive zinnwaldite mineralization on the Property related to the large 'greisen' zone that resides at the contact between the Devonian-aged granite complex, and the Proterozoic metasediments and volcanics over which the Ackley claim blocks lie."
Assay results from grab samples taken during recent field work will be published in subsequent press releases. The Company also awaits additional confirmation of the zinnwaldite mineralization through detailed petrographic analysis of the grab samples.
Additional Information About Zinnwaldite
Zinnwaldite is a potassium-lithium-iron-aluminum-silicate-hydroxide-fluoride phyllosilicate mineral within the mica group that typically occurs in greisens, pegmatites and quartz veins, and is often associated with tin ore deposits.
In general, zinnwaldite ore is the least energy- and capital-intensive hard rock mining alternative to a lithium-brine operation with respect to the production of lithium hydroxide, especially when compared to spodumene ore. Whereas spodumene concentrate must undergo two separate "high temperature" roast cycles prior to the production of lithium hydroxide, zinnwaldite concentrate only has to undergo a single "medium temperature" roast cycle in order to produce lithium hydroxide.
Additionally, unlike spodumene which has a tendency to lose its lithium content when exposed to ambient weather conditions, zinnwaldite is not subject to weather conditions as a means of production, which allows for greater certainty of supply and control of production.

About the Ackley Property
Ackley comprises three claim blocks that collectively span an area of 4,550 hectares located less than two hours' drive from St. John's. The claim blocks overlie portions of the contact zone of a large Devonian-aged granite complex with Proterozoic metasediments and volcanics, parts of which are "greisened", or hydrothermally altered, that is similar in age and lithology to the Mount Pleasant deposit in New Brunswick and the East Kemptville deposit in Nova Scotia. Limited historical exploration work across the Main Claim Block by companies including Esso Minerals, American Zinc, Inco and others, discovered occurrences and anomalies of lithium, tin, molybdenum, tungsten and REEs.
Recent magnetometer survey work over part of the Main Claim Block indicates that the altered contact zone may be extensive, covering several square kilometres. Recent limited prospect sampling and historical Esso trenches across the Main claim block returned assays of up to 0.91% lithium oxide, 5.0% molybdenum, 0.67% tin and 1-5% fluorine on surface. Newfoundland government survey maps of this region report some of the highest lake sediment values for REEs on the entire island.

Investor Insight
Leveraging early-stage land acquisition, accelerated drilling and a strong strategic partnership, Lithium Africa delivers maximum exploration efficiency, capital leverage and de-risked lithium discovery upside at scale.
Overview
Lithium Africa is an exploration company purpose-built to capitalize on the next cycle of lithium demand. Its strategic mission is to discover, de-risk and monetize Tier 1 lithium assets through data-driven targeting, aggressive fieldwork and value-driven exits. The company's unique 50/50 joint venture with Ganfeng Lithium is the cornerstone of its strategy, providing both financial leverage and industrial alignment at the earliest stages of project development.
Africa remains largely underexplored for lithium despite sharing geological similarities with major hardrock lithium belts in Canada and Australia. Lithium Africa is the first company to systematically deploy a multi-jurisdictional discovery strategy across the continent – combining top-tier geology with capital efficiency and strategic clarity.
At the heart of Lithium Africa’s model is its joint venture with Ganfeng Lithium, one of the top two lithium chemical producers globally. The 50/50 JV, established in 2023, enables Lithium Africa to double its capital efficiency, with $1 raised equating to $2 spent on exploration. The partnership provides unmatched advantages: access to Ganfeng’s downstream processing know-how, established customer relationships with Tier 1 OEMs, and a long-term offtake framework that allows Lithium Africa to retain flexibility and optionality on any asset monetization.
Lithium Africa does not intend to develop or operate mines. Instead, the business model is designed around efficient land acquisition, aggressive de-risking via trenching, sampling, and early drilling, and ultimately monetizing high-value discoveries through royalties, sales or carried interests. In a down market, the company is actively pursuing counter-cyclical M&A opportunities to acquire stranded or undercapitalized lithium assets. With this strategy, Lithium Africa provides shareholders exposure to world-class discovery upside with significantly reduced financing risk.

Key Projects
Zimbabwe
Birthday Gift Project (Flagship)
The Birthday Gift project is Lithium Africa’s flagship asset and highest-priority exploration target. Located along a >12 km pegmatite corridor, the project hosts three parallel, flat-lying spodumene-bearing pegmatites within metasediments. Surface trenching has returned multiple significant intercepts, including 100 m, 67 m, and 55 m widths with true thicknesses averaging ~35 m. Rock chip samples from fresh spodumene zones have returned assays as high as 5.25 percent lithium oxide. More than 3,000 geochemical samples have been collected, and a 1,500-meter RC drill program commenced in January 2025 to test a 1,300-meter strike length.
The pegmatites remain open at depth and along strike. SGS South Africa is performing ICP assay analysis, and environmental permitting and trenching on the western trend are ongoing.
The Birthday Gift asset has strong potential to support an inaugural resource estimate by late 2025.
West Africa
Torakoura in Bougouni District, Mali
Lithium Africa controls six highly prospective licenses in Mali, located within the prolific Bougouni Basin, home to Leo Lithium’s Goulamina project, one of the world’s largest spodumene deposits. The Torakoura permit is situated along the same structural corridors and granitic host rocks. Surface exploration has identified spodumene-bearing pegmatites, supported by strong lithium and pathfinder anomalies from historic soil sampling.
Initial drilling at Torakoura began in 2024 but paused for LIBS-to-ICP calibration. A new RC drilling campaign resumed in Q4 2024. These permits offer substantial scale and proximity advantages in a well-established lithium district with proven permitting and development pathways.
Adzopé & Regional Licenses, Côte d’Ivoire
In Côte d’Ivoire, Lithium Africa holds four early-stage but highly promising permits totaling 1,254 sq km. The Adzopé license has returned rock samples with lithium oxide values up to 0.98 percent. Field mapping and lithological sampling have been completed, and a 21,700-meter auger drilling program is planned to refine targets for follow-up RC and core drilling. The region is emerging as a new pegmatite belt in West Africa, and Lithium Africa has first-mover status in building a pipeline of discovery-stage projects.
Kobikoro Project, Guinea
The Kobikoro project in southeastern Guinea consists of four licenses covering 376 sq km in the Archean Kinema-Man domain. This district is part of the underexplored Kissidougou pegmatite belt. Historical stream sediment geochemistry conducted by BRGM highlights multiple anomalous trends in lithium, tantalum and niobium. The standout feature is a 20 km-long lithium-tantalum-niobium anomalous zone aligned with regional structures and underlain by fractionated granite intrusions.
Morocco
Bir El Mami
In 2024, Lithium Africa acquired a 585 sq km, district-scale land package in the Bir El Mami region of Morocco, located on the northern extension of the Tasiast greenstone belt. The project is notable for its spodumene-bearing pegmatites confirmed by surface rock samples, which include lithium values up to 862 parts per million (ppm), and historic soil anomalies up to 363 ppm. The region is emerging as a key lithium district given Morocco’s favorable trade agreements and a growing domestic EV battery manufacturing base. Lithium Africa is currently Morocco’s only major lithium concession holder, and early-stage target identification is underway as of Q1 2025. The company is well positioned to be Morocco’s lithium sector leader and consolidator.
