Drilling Targets Defined – Bananal Valley tenement, Lithium Valley, Brazil

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.

Figure 1 shows the location of the Salinas Project tenements in relation to Latin resources Collina deposit and to other tenements held by major explorers including Rio Tinto.

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.

Lithium anomalies are plotted as anomalous catchments (released 22 August 2024) to indicate the large prospective area that is present.

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.

Inside Billionaire Gina Rinehart's Key Mining Investments (Updated 2024)

Australian billionaire Gina Rinehart has become a formidable force in the global mining industry.

After taking the helm of her father’s iron ore mining firm Hancock Prospecting in 1993, Rinehart embarked upon a diversification strategy that has vastly expanded her resource empire. Now Australia’s richest person, Rinehart has investments in many of the world’s most strategic commodities such as lithium, rare earths, copper, potash and natural gas.

One of those investments is Arafura Rare Earths (ASX:ARU,OTC Pink:ARAFF), which even in a low price environment for rare earths has managed to secure nearly AU$1.5 billion in debt financing in mid-2024 to advance its Nolans project in the Northern Territory. With a 10 percent equity stake, Rinehart’s Hancock Prospecting is Arafura's largest shareholder.

In addition to Arafura, entrepreneur Rinehart’s investment portfolio also contains other ex-China, green-transition-focused companies such as Australian lithium firm Liontown Resources (ASX:LTR,OTC Pink:LINRF), as well as rare earths producers MP Materials (NYSE:MP) and Lynas Rare Earths (ASX:LYC,OTC Pink:LYSCF). Rinehart’s role in the acquisition of Azure Minerals’ Andover lithium project in Western Australia alongside lithium giant SQM (NYSE:SQM) also made headlines in the past year.

Argentina’s Lithium Resource Holds Potential to Power the Global Energy Transition

As the global energy landscape shifts towards cleaner alternatives, Argentina's position within the Lithium Triangle is emerging as a focal point for savvy investors.

This geological marvel, spanning Argentina, Bolivia and Chile, holds over half of the world's known lithium reserves, with Argentina poised to become a linchpin in the global lithium supply chain.

The country's vast salt flats, or 'salares', are not just natural wonders but veritable treasure troves for those looking to capitalise on the burgeoning demand for electric vehicles (EVs) and renewable energy storage solutions.
