Gold Mountain Limited (ASX: GMN) (“Gold Mountain” or “the Company” or “GMN”) is excited to announce it has received 224 soil samples from the southern section of the Salinas II Project in the Bananal Valley in Brazil. This new data has helped the team define a 14-hole drill program to test 10 high-priority lithium anomalies, some of which are coincident with outcrops of weathered pegmatite. The potential of this emerging Lithium district is highlighted by Latin Resources Collina Lithium Deposit (70.9Mt @ 1.25% Li2O), which lies along regional structural strike from GMN’s Salinas II Project.
Highlights
Work Undertaken
- Assays received from 100 and 200 metre spaced soil sampling lines with soil samples taken at 50 metre intervals.
- Lithium anomalies identified over the 1.5 km strike extent of the soil grid with coincident Be, Rb, Sn and Tl anomalies.
- No lithium anomalies found in areas of laterite however tin anomalies as well as quartz and tourmaline occurrences suggest pegmatite extensions under the laterite.
- Drill holes defined so environmental permits can be obtained to allow drilling to take place.
Future Workplan
- Obtain environmental permits for drilling
- Extra soil lines in the NW of tenement to follow up anomalies previously defined
- Continue detailed mapping to refine currently identified pegmatite trends
- Drilling of the lithium targets identified.
Details
Results from exceptionally high value stream sediment sample have been followed up with soil samples and grid based mapping in the southern part of 831.700/2022 and drilling targets had been identified.
Mapping prior to and during soil sampling identifies numerous small pegmatites and some larger pegmatites to a maximum of 10 metres wide. Areas of large quartz boulders, possibly quartz cores to pegmatites, were also mapped and in places are coincident with lithium and lithium pathfinder anomalies. Pegmatites cross cut and are younger than the foliation in the host G3 type granite.
Regional structure from geophysics and from topography shows a strong NE to ENE trend, subparallel to the Latin Resources “Lithium Corridor.” Drilling will be oriented at 90 degrees to the regional trend initially, as the most probable major pegmatite orientation direction.
Strong vertical zonation in the lithium pegmatite geochemical responses are present and close attention to the location of laterite and the old lateritised surface is critical to interpretation of where lithium pegmatites may be concealed by leaching of lithium.
Drill targets were defined by lithium anomalies and by occurrences of pegmatite or extensive float of pegmatite minerals, lithium pathfinder elements, large quartz boulders or anomalous quartz concentrations.
The lateritic weathering zone is estimated from mapping to be up to 50 metres thick within the tenement, but locally may be significantly thicker. Drilling below this weathered layer is essential to get analyses that reflect the actual grade of any pegmatites present. Within the weathering zone low values of lithium are expected from potentially economic pegmatites.

This region contains two producing mines, the undeveloped Colina deposit, and several prospects with significant exploration activity. While close proximity does not guarantee similar results it does provide evidence to assist in targeted exploration.
Mapping and soil sampling in the western Bananal Valley tenement, 831.700/2022, has defined areas of laterite as well as various larger pegmatite and quartz occurrences.
Figure 2 shows the extensive high order stream sediment target zones in the Bananal valley tenement, with their follow up soil lines and potential pegmatite mineral occurrences, including green tourmaline, indicating highly evolved pegmatites.

Lower order anomalies in the northeast are still considered highly prospective, with lower order results due to more intensive weathering and leaching of surface rocks.

Atlantic Lithium
Investor Insight
Atlantic Lithium is advancing Ghana’s first lithium mine at Ewoyaa, a fully permitted, strategically located project ready to supply global battery markets. With strong local support and a clear path to production, the company is positioned for near-term growth and long-term impact in the energy transition.
Overview
Atlantic Lithium (AIM:ALL,ASX: A11,GSE:ALLGH,OTCQX: ALLIF) is an Africa-focused lithium exploration and development company advancing its flagship Ewoyaa Lithium project through to production as Ghana’s first lithium mine.
Despite its long mining history, favourable regulatory climate and stable political backdrop, Ghana remains largely overlooked as an investment jurisdiction for battery metals. Situated on the West African coast, the country boasts a strong strategic location, between Europe, the Americas and Asia, to serve the global battery metals market. Ghana is also home to an abundance of mineral wealth, with c. 180,000 tonnes of estimated lithium resources.
Atlantic Lithium intends to produce spodumene concentrate capable of conversion to lithium chemicals for use in electric vehicle batteries and energy storage, aiming to support global decarbonisation.
A definitive feasibility study (DFS) released in June 2023 shows that Ewoyaa has demonstrable economic viability, low capital intensity and excellent profitability.
Through simple open-pit mining, three-stage crushing and conventional Dense Medium Separation (DMS) processing, the DFS outlines the production of 3.6 Mt of spodumene concentrate over a 12-year mine life, which will make it one of the largest spodumene mines by production capacity globally.
The Ewoyaa Lithium Project was awarded a Mining Lease in October 2023, an EPA Permit in September 2024, and a Mine Operating Permit in October 2024.
Having secured all of the permits required to begin construction, Atlantic Lithium currently awaits parliamentary ratification of the Ewoyaa Mining Lease, which was issued by the Ministry of Lands and Natural Resources in October 2023.
The JORC mineral resource estimate at Ewoyaa now stands at 36.8 million tons (Mt) at 1.24 percent lithium oxide, 81 of which is now in the higher confidence measured and indicated categories (3.7 Mt at 1.37 percent lithium oxide in the measured category, 26.1 Mt at 1.24 percent lithium oxide in the indicated category, and 7 Mt at 1.15 percent lithium oxide in the Inferred category).
The residents of the project-affected communities in Ghana’s Central Region have voiced their strong support from the advancement of the project towards production.

Project Funding
The development of the project is co-funded under an agreement with NASDAQ and ASX-listed Piedmont Lithium (ASX: PLL), under which Piedmont is required to contribute the first US$70m of Development Costs, as defined in the agreement, as sole funding to complete its earn-in to 50% of Atlantic Lithium's ownership of the project, with all Development Costs and other project expenditure equally shared by both Atlantic Lithium and Piedmont thereafter.
In accordance with the agreement, which is intended to result in the construction of the project and the achievement of initial spodumene production, Piedmont will earn the rights to 50 percent of all spodumene concentrate produced at Ewoyaa at market rates, providing a route to consumers through several major battery manufacturers, including Tesla.
The Minerals Income Investment Fund (MIIF), Ghana’s minerals sovereign wealth fund, has also agreed to invest US$27.9 million at project-level to acquire a 6% contributing interest in the project and Atlantic Lithium’s Ghana Portfolio. The project-level investment represents Stage 2 of its Strategic Investment in the company.
This follows Stage 1 of its Strategic Investment, comprising MIIF’s Subscription for US$5 million Atlantic Lithium shares, which was completed in January 2024, resulting in MIIF becoming a major strategic shareholder in the company.
MIIF’s Strategic Investment is intended to expedite the development of the project towards production.
In addition, noting that Ewoyaa is one of the most advanced undeveloped hard rock lithium projects globally, Atlantic Lithium continues to engage with parties across the battery metals supply chain who express inbound interest in lithium products from Ewoyaa.
In doing so, Atlantic Lithium aims to expedite and de-risk the development of the Project, realise attractive terms for any offtake contracted and secure well-credentialled partners that will support the company's and Ghana's objectives of supplying lithium into the global market.
Ghana
Ghana is a well-established mining region with access to reliable, existing infrastructure and a significant mining workforce. There are currently 16 operating mines in the country.
Already the largest taxpayer and employer in Ghana’s Central Region, Atlantic Lithium is expected to provide direct employment to over 900 personnel at Ewoyaa and, through its community development fund, whereby 1 percent of revenues will be allocated to local initiatives, will deliver long-lasting benefits to the region and Ghana.
Through its proven lithium discovery, exploration and evaluation methodologies, Atlantic Lithium has the potential to capitalise on its extensive exploration portfolio and deliver upon its objectives of becoming a leading producer of lithium in West Africa.
