Brightstar Resources Limited (ASX: BTR) (Brightstar) is pleased to announce results from the surface and underground drilling programs conducted at the Second Fortune Gold Mine, located south of Laverton, WA.
HIGHLIGHTS
- First diamond drilling assays returned from the Second Fortune underground mine by Brightstar delivers high grades within and beneath the current forward mine plan
- The deepest hole drilled to date at Second Fortune, SFRCD2408, returned +31g/t Au from a 0.3m downhole intercept at 465.75m depth, proving that the high grade Second Fortune mineralisation continues at depths +400m below surface
- Drilling assays highlight the high-grade and narrow-vein nature of the Second Fortune orebody, which has shown strong geological consistency over recent years of operational history, including:
Surface holes:
- SFRCD2404A:
- 0.57m @ 21.3g/t from 426.55m (12 gram-metres, gm)
- SFRCD2405

- SFUDD0093
- 0.49m @ 19.22g/t Au from 103.6m (10gm)
- Drilling intercepts are ~100m below currently developed levels on the 1065 level and provide significant confidence in mine life extension at Second Fortune.
- Drilling targeted mining areas within and below the current 12 month mine plan in order to improve the classification of the Mineral Resource Estimate, provide confidence on future mine life extension and enhance mine planning and scheduling activities
- Following the success of this program, Brightstar has commenced further underground drilling to further improve geological knowledge and confidence of CY25 production
Brightstar’s Managing Director, Alex Rovira, commented“The desired outcome of our combined surface and underground drilling program was to infill certain areas to increase confidence in the resource model, whilst also taking the opportunity to drill deeper holes outside and below the current mine plan.
We are delighted with the results which successfully proved that the high-grade Second Fortune vein system continues at depths well below the current mine plan. This result provides a compelling target for Brightstar to explore further in order to extend the mine life at Second Fortune. Accordingly, we have expedited plans to complete further underground drilling to commence imminently, which will inform an upgraded Mineral Resource Estimate this CY24 with the intent of potentially supporting the declaration of Ore Reserves and formal production outlook.
We look forward to sharing ongoing results as they are received, with assays still pending from various programs across the Brightstar portfolio including previously announced RC and Diamond drill programs”.

TECHNICAL DISCUSSION
The Second Fortune deposit lies at the southern end of the Laverton Tectonic Zone which lies on the eastern margin of the Norseman-Wiluna Belt. Gold mineralisation occurs within a north-to-northwest striking sequence of intermediate to felsic volcaniclastic rocks and subordinate sediments, intruded by irregular, narrow, tabular bodies of albite porphyry.
Gold mineralisation is associated with an arcuate narrow quartz vein system (0.2m to 2m width) that has a strike of over 600 metres and dips steeply to the west. Within the vein there is locally abundant pyrite with wall rock alteration characterised by a thin selvedge of sericitic and chlorite alteration providing a strong mineralisation vector.
The Second Fortune vein system consists of the Main Lode and a number of subsidiary lodes, the Hanging wall and Footwall lodes which are located within ~10m of the Main lode, and the Caturra lode to the West.
Linden Gold Alliance Limited (Linden) acquired the Second Fortune Gold Project in 2020 and moved quickly to bring the project back into production, achieving its first gold pour within seven months in April 2021. In 2023, Linden produced in excess of 13,000oz gold, with ore processing through Genesis Minerals Limited’s Gwalia processing facility, and subsequently merged with Brightstar in 2024.
The purpose of the combined surface and underground drill programs were to infill and confirm the resource within the planned underground mine design, and to target extensions at depth to assess potential for lode continuity.

Investor Insight
A gold-focused emerging gold producer with a clear pathway to production growth, Brightstar Resources presents a compelling investment case driven by its mining and development hubs strategy and a district-scale resource opportunity.
Overview
The price of gold stays strong. In April 2024, the yellow metal’s price passed US$2,400 per ounce for the first time. The reason is multifaceted. The world teeters on the brink of a severe recession while some markets attribute the increase to safe haven rush. Amidst ballooning interest rates, bank failures and falling bond yields, demand for gold continues to rise. At this precise moment, gold is simultaneously an excellent portfolio diversifier and a compelling hedge against ongoing inflation — particularly if one invests in the right company.
Brightstar Resources (ASX:BTR) aims to be that company. An emerging mining and development company, Brightstar occupies a strategic land position of roughly 1,200 square kilometers in the Sandstone Greenstone Belt, 300 square kilometers in the Laverton Tectonic Belt and 80 square kilometers of the Menzies Shear Zone.
The company also owns an existing processing facility that can potentially provide tremendous shareholder value in a low-capital cost restart scenario.
That plant, once fully refurbished and operational, could prove a key differentiator for the company, enabling fast gold production at a low capital cost. This is especially noteworthy given that many other gold companies trading on the ASX are largely focused on greenfield exploration and development. Even once those companies discover a promising resource, mining and processing facilities would still need to be built, undertakings which can incur significant upfront capital costs and take several years.
Brightstar's Laverton gold assets are all centered on a 100 percent-owned 300-square-kilometer tenure in the Laverton Tectonic Zone and all within 70 kilometers of the Laverton Processing Plant. Additionally, all resources within this zone are open along strike and at depth. Only minor drilling programs have been conducted in recent years, paving the way for significant exploration upside with the potential for further regional and greenfields discoveries.
Brightstar also owns 100 percent of the Menzies Gold Project, a contiguous land package of granted mining leases over a strike length of roughly 20 kilometers along the Menzies Shear Zone and adjacent to the Goldfields Highway.
In 2023 and 2024, the company announced a mineral resource upgrade to the Cork Tree Well deposit (Laverton gold project) and also delivered two maiden mineral resource estimates at the Link Zone and Aspacia deposits (Menzies gold project). This has grown the total group MRE by approximately 150 koz gold through organic exploration. Brightstar also recently announced the results from DFS-level metallurgical testwork programs at Cork Tree Well with returned recoveries over 90 percent, including a high gravity gold content, ranging from 25 percent - 60 percent.
The company has also acquired 100 percent of the shares and options of Linden Gold Alliance, a gold producer, developer and explorer with existing mineral resources of 350 koz @ 2.1 g/t gold near Brightstar in the Laverton district. Brightstar’s MRE has reached 1.1 Moz gold across the Menzies and Laverton projects, with an additional 0.35 Moz gold in resources added after the successful acquisition of Linden Gold Alliance.
In August 2024, Brightstar entered into a scheme implementation deed to acquire 100 percent of Alto Metals (ASX:AME), which owns the Sandstone gold project located in East Murchison. The project has a current mineral resource of 1.05 Moz of gold at 1.5 g/t.
Brightstar also completed the acquisition of the gold rights at the Montague East gold project (MEGP) from Gateway Mining Limited (ASX:GML). The project is located 70 km from the Sandstone gold project. The acquisition adds a further 9.6 Mt @ 1.6 g/t gold for 0.5 Moz gold to Brightstar’s JORC Mineral Resource Estimate, giving the company a total mineral endowment of 38.3 Mt @ 1.6 g/t gold for 2.0 Moz gold.
The acquisition of the MGEP from Gateway Mining and 100 percent of Alto’s shares creates a third district-scale resource base for the company called the Sandstone Hub. Upon consolidation of the Laverton, Menzies and Sandstone hubs, Brightstar’s mineral resources would reach 3 Moz at 1.5g/t gold.
Subsequent to the deal with Alto Metals, Brightstar entered into a $4 million drill-for-equity agreement with Topdrill to aggressively advance the consolidated Sandstone gold project. The deal strengthens Brightstar's financial capacity to fulfill its multi-hub exploration and development strategy, which includes the Menzies, Laverton and Sandstone hubs.

Additional Targets Identified from Gravity Geophysics at Wagyu Project, Pilbara WA
HIGHLIGHTS
- Completion of Passive Seismic and Ground Gravity surveys across the dry Yule River bed at the Wagyu Gold Project in Pilbara, WA
- Several new gravity anomalies have now been identified, which may indicate the presence of more gold-mineralised intrusions, similar to those intersected in 2024 aircore drilling
- Enhanced geological connectivity established by linking data from the east and west sides of the tenement
- Both geophysics surveys were completed with “zero impact” on this culturally sensitive area
- This is the third ground gravity survey and the second passive seismic survey to take place at the Wagyu Project, with previous surveys outside the river completed in April and May 2024
- Additional targets 8 and 10 confirmed on east side of the project from gravity survey
- 3000m of Reverse Circulation Drilling to commence imminently
- The Wagyu Project is located in the Central Pilbara’s fast-emerging gold region, adjoining De Grey Mining (ASX:DEG) tenure containing its ~11.2Moz1 Hemi Gold deposit
The Wagyu Gold Project, located within a fast-emerging gold mineralised corridor, represents a highly prospective Gold opportunity ~9km within the same mineralised trend as De Grey Mining’s (ASX:DEG) Hemi Gold Deposit containing ~11.2 Moz1 (refer to Figure 1) in the Central Pilbara.
Figure 1: Location Map showing NAE’s Wagyu Gold Project (E47/2974) in the Gold Mineralisation Corridor shared with De Grey’s significant gold Mineral Resources, including Hemi, Mt Berghaus and Calvert.
The Hemi Gold Mineral Resource was last updated by De Grey Mining on 14 November 20241. The estimate is for 264Mt @ 1.3g/t Au for 11.2Moz, which can be broken down into 13Mt @ 1.4g/t for 0.6Moz, 149Mt @ 1.3g/t Au Indicated for 6.3 Moz, and 103Mt @ 1.3g/t Au for 4.3 Moz Inferred.
NAE confirms that it is not aware of any new information or data that materially affects the information included in De Grey’s reported Mineral Resources referenced in this market announcement. To NAE’s full knowledge, all material assumptions and technical parameters underpinning the estimates in the relevant market announcements continue to apply and have not materially changed.
NAE Executive Director Joshua Wellisch commented:
"The completion of these Geophysical Surveys and identification of new targets marks a pivotal step in our exploration efforts and stakeholder relations at Wagyu. With the support of the Kariyarra People, we have gathered data that links structures and anomalies across the tenement, providing a foundation of our geological understanding. We look forward to using these insights to unlock further potential at Wagyu in the lead up to the imminent 3000m RC Drill Programme.”
Geophysical Surveys and Geological Continuity
The Passive Seismic (Tromino) and Ground Gravity surveys at Wagyu have provided valuable data across the Yule River bed, enhancing the geological connectivity between the east and west portions of the tenement. The Passive Seismic survey, conducted at 200-meter intervals across nine lines, offers insights into bedrock continuity, while the Ground Gravity survey (Figure 4), with spacings of 200m x 200m and infill at 50m x 50m over specific targets, reveals density contrasts associated with mineralisation.
