Octava Minerals Limited (ASX:OCT) (“Octava” or the “Company”), a Western Australia focused explorer of the new energy metals REE’s, antimony, gold & nickel, is pleased to provide an exploration update on its Western Australian exploration projects.
Highlights
- Mobilisation of crews for detailed geophysical survey over the identified 10km antimony corridor at Yallalong.
- Heritage clearance confirmed over two priority antimony drill targets, Discovery and Central, in preparation for drilling to commence.
- Drilling to focus on extending the existing high-grade antimony mineralisation along strike and at depth over the Discovery target.
- Heritage surveys over next 2 priority antimony targets planned for early December.
- Drill site preparation underway at the large Byro REE & Li project in readiness for metallurgical core drilling to commence mid-November.
Yallalong Antimony
The Yallalong project is located ~ 220km to the northeast of the port town of Geraldton in Western Australia and comprises two granted Exploration Licences, E70/5051 (100% owned) with an exploration area of 63.4km2 and E09/2823 (100% owned) with an exploration area of 94km2.
The antimony (Sb) mineralisation identified at Yallalong appears to occur within a 10km north- south striking mineralised corridor that is interpreted to be related to a structural corridor between the Darling and Woodrarung faults. (Refer ASX announcement 17 September 2024)
Octava will begin detailed gravity and seismic surveys over the identified antimony corridor at Yallalong. Teams will mobilise on ground in the coming days. The geophysical surveys will provide details on the key structures such as shears & faults which act as conduits to mineralising fluids. It will also provide better understanding of the key lithological boundaries.
Figures 1 Outcrop at the Discovery Prospect, Yallalong Project
POW applications covering the 4 priority antimony targets have been approved. These approvals cover the exploration and planned drilling of the antimony targets at the Yallalong Project.
The two priority targets, Discovery and Central, have confirmed heritage clearance, clearing the path for drilling to commence. Heritage surveys covering the No.4 and North targets are expected to be completed by early December in preparation for drilling early in the new year.
The drilling at the Discovery target will focus on extending the previously intersected high-grade antimony mineralisation, both along strike and at depth, with the aim of outlining an antimony resource. Drilling at the Central target will test anomalous antimony at surface, as no drilling has been carried out previously.
Byro
The Byro Project is located on the Byro Plains of the Gascoyne Region, Western Australia, 220 km south-east of Carnarvon and 650 km north of Perth. The Byro project is prospective for rare earths (REE’s), lithium and base metals. (Refer ASX announcement 24 January 2024)
Previous GSWA regional soil sampling and RC drilling has recorded wide areas and large intercepts of anomalous REE, Li & other elements including V and Zn. Previous work identifies an area of mineralisation occurring over more than 30km in strike length and 15km in width. See Figure 2.

Figure 1 – Pursuit’s 99.5% Li₂CO₃ Sample Ready for Dispatch to Potential Offtake Partners
In relation to the dispatch of samples, Pursuit Managing Director & CEO, Aaron Revelle, said:
“Achieving 99.5% lithium carbonate purity is a major technical milestone for Pursuit and a clear demonstration of the capability embedded within our flowsheet, team, and pilot plant infrastructure. It not only validates the compatibility of our process design with Rio Grande Sur brines but also confirms our ability to deliver a consistently high-quality product suited to a wide range of industrial and energy storage applications. Dispatching these samples to potential offtake partners is a critical first step in our commercialisation pathway, enabling product qualification and accelerating engagement with strategic customers in tough market conditions. As we transition into the next phase of development, our focus is firmly on advancing feasibility for our 5,000tpa operation and securing long-term partnerships that will underpin the future production and growth of the Rio Grande Sur Project.”
Initial pilot production at Pursuit’s 250tpa Pilot Plant in Salta successfully produced 15 kilograms of lithium carbonate at 98.9% purity, validating both the compatibility of the Rio Grande Sur brine and the efficiency of the Company’s conventional processing flowsheet. To enhance product quality and simulate potential refinement steps at commercial scale, a portion of this material was further treated at bench scale using fractional crystallisation (FX) and ion exchange (IX) techniques. These post processing steps upgraded the product to 99.5% purity, meeting established benchmarks for technical-grade lithium carbonate.
The final product assays confirm not only the effectiveness of Pursuit’s downstream purification strategy but also the scalability and robustness of its broader flowsheet. This achievement represents a critical milestone on the path to commercial readiness supporting key feasibility assumptions, validating end product quality, and enabling active engagement with prospective offtake partners.
Pursuit is well positioned to undertake additional small-batch production as required to meet partner qualification needs and advance strategic discussions. Furthermore, it demonstrates Pursuit’s capability to produce high-purity lithium carbonate suitable for industrial use, with potential to meet battery-grade specifications through additional refinement.

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.
