  • Gold Mountain's next exploration activities include deeper drilling, infill sampling and additional metallurgical evaluation.

Gold Mountain Limited (ASX:GMN) is an Australian mineral exploration company with interests in rare earth elements and other minerals across Brazil. Its Brazilian portfolio includes exploration areas in the Jequié region of Bahia, where the company is assessing rare earth mineralisation through geochemical sampling, auger drilling and metallurgical studies. With its shares closing at AUD 0.042 on 3 November 2026, down AUD 0.005 during the session, Gold Mountain (ASX:GMN) continues advancing its Brazilian exploration programme following the sale of its Papua New Guinea assets in January 2026. The portfolio change coincided with additional equity funding and a series of drilling results from the Capivara prospect during the September quarter.

Brazilian Portfolio Becomes Central to Exploration Strategy

Gold Mountain (ASX:GMN) completed the sale of its Papua New Guinea assets on 22 January 2026, narrowing its exploration activities towards Brazil.

The company's Brazilian interests include the Down Under Project in Bahia, which contains the Capivara prospect and other exploration targets.

Additional areas within its broader portfolio include Irajuba, Ayrton Senna and interests associated with the Araxá region.

These projects provide exposure to different mineral systems, including rare earth elements, niobium and other commodities.

During 2026, the company concentrated much of its reported fieldwork on identifying and evaluating rare earth mineralisation at Capivara.

The exploration programme involved shallow auger drilling, geological interpretation and sampling to establish the distribution of mineralised zones.

However, these activities remain at an early stage, and the company has not established a mineral resource estimate for its Brazilian rare earth prospects.

Capivara Auger Drilling Identifies Rare Earth Mineralisation

Gold Mountain (ASX:GMN) reported further auger drilling results from Capivara on 15 September 2026.

The reported results included an interval of 12 metres grading 1,283 parts per million total rare earth oxides from a depth of 10 metres.

Within that interval, eight metres returned 1,513 parts per million total rare earth oxides.

The company also reported magnet rare earth oxide proportions of approximately 38% to 42% in selected results, with one reported value reaching 48%.

These proportions describe the composition of the rare earth mineralisation and should not be interpreted as metallurgical recovery rates.

Several auger holes ended at shallow refusal or encountered hard duricrust, limiting the depth of geological assessment.

Consequently, the continuity and characteristics of mineralisation beneath those intervals remain insufficiently tested.

Additional results were announced on 30 September 2026, contributing to the company's interpretation of the prospect.

Future drilling will be required to assess mineralisation at greater depths and determine whether the reported intercepts form part of a continuous geological system.

Metallurgical Testing and Further Exploration Requirements

Alongside drilling, Gold Mountain (ASX:GMN) has undertaken preliminary metallurgical investigations to assess the potential recovery of rare earth elements.

Earlier testwork reported recoveries of up to 65.9% for rare earth elements excluding cerium and approximately 63.6% for magnet rare earth elements.

These results relate to the specific samples and processing conditions tested. They do not establish recovery performance for a future commercial operation.

Additional metallurgical work will be needed to examine variations in mineralogy, processing conditions and potential recovery characteristics across the deposit.

The company has also identified deeper diamond drilling and infill auger drilling as potential next steps at Capivara.

Such activities would help evaluate the depth, grade distribution and geological continuity of the mineralisation.

Any future mineral resource estimate would require sufficient geological information, representative sampling and appropriate technical assessment.

Equity Funding and September Quarter Developments

Gold Mountain (ASX:GMN) announced an AUD 5.5 million Placement on 29 April 2026, followed by a further AUD 4.5 million placement on 30 June 2026.

Together, the announced placements totalled approximately AUD 10 million before associated transaction costs.

The funding was intended to support exploration activities across the company's Brazilian projects.

Gold Mountain also announced an exclusive twelve-month right to acquire a historical tungsten project on 5 October 2026.

The arrangement provides an opportunity to evaluate another mineral asset, although any Acquisition remains dependent on the applicable option terms.

On 29 October 2026, the company released its September quarterly activities report and lodged a proposed issue of securities.

The proposed securities issue requires assessment of its final terms before its implications for the company's Capital Structure can be determined.

As an exploration-stage company, Gold Mountain remains dependent on available cash, future funding arrangements and exploration results to support continued field activities.

Exploration Uncertainty and Development Outlook

Gold Mountain (ASX:GMN) has not established a commercial rare earth operation at its Brazilian projects.

The reported Capivara intercepts provide geological information, but further drilling is required to establish mineralisation continuity and assess its potential scale.

Metallurgical recoveries, permitting requirements, future Capital Expenditure and Commodity market conditions will also influence any subsequent development assessment.

The company has not reported a mineral resource estimate for the Brazilian rare earth prospects discussed here, and exploration results should not be interpreted as evidence of economically recoverable reserves.

Further technical results and funding disclosures will therefore remain important in evaluating the progress of its exploration programme.

Key Insights

Gold Mountain (ASX:GMN) has concentrated its 2026 activities on Brazilian rare earth exploration following the disposal of its Papua New Guinea assets. Auger drilling at Capivara has identified rare earth mineralisation, while preliminary metallurgical studies provide initial recovery information. The company has also announced approximately AUD 10 million in equity placements to support exploration. Deeper drilling, further metallurgical assessment and future funding disclosures will be important in determining the next stage of its Brazilian programme.
