What Do Australian Mines’ Latest Boa Vista Drilling Results Reveal About Gold Potential?
Australian Mines Limited has reported promising initial assay results from its 2025 drilling campaign at the Boa Vista Gold Project in Brazil, confirming broad and continuous gold mineralisation with significant high-grade zones.
- First three drill holes confirm broad gold mineralisation
- VGADD0002 delivers 120m at 1.34 g/t Au including 16m at 3.53 g/t Au
- Results support continuity of mineralised system at Boa Vista
- Historic inferred resource of ~336,000 oz gold at VG1 prospect
- Eight drill hole assays pending, further updates expected
Initial Drilling Success at Boa Vista
Australian Mines Limited (ASX – AUZ) has released the first assay results from its 2025 diamond drilling program at the Boa Vista Gold Project in Brazil. The initial three holes of an 11-hole campaign have returned encouraging gold intercepts, confirming broad zones of mineralisation consistent with the company’s exploration model.
The standout result comes from hole VGADD0002, which intercepted 120 metres grading 1.34 grams per tonne (g/t) gold from 117 metres depth, including a higher-grade 16-metre section at 3.53 g/t. This intercept ranks as the second-best gram-metre result recorded at Boa Vista to date, underscoring the prospectivity of the mineralised system.
Context and Historical Significance
Boa Vista’s VG1 prospect hosts a historic inferred resource estimated at approximately 336,000 ounces of gold, based on a 2013 NI 43-101 technical report. The mineralisation extends over a 2-kilometre soil anomaly and remains open along strike and at depth, with previous drilling revealing multiple high-grade intercepts exceeding 20 gram-metres, a commonly used threshold for prospective gold mineralisation.
The recent drilling results reinforce the potential for a continuous mineralised system along strike and down dip, with broad intercepts and internal higher-grade zones aligning well with historical data. Australian Mines is advancing its geological interpretation to refine the mineralisation wireframes and prioritise follow-up drilling.
Ongoing Exploration and Next Steps
With assays pending for eight additional holes, Australian Mines plans to integrate the full dataset to better understand the geometry and continuity of the mineralised envelope. The company aims to update its targeting model and exploration strategy accordingly, focusing on resource definition potential and testing extensions along strike and at depth.
CEO Andrew Nesbitt expressed optimism about the campaign’s progress, highlighting the quality of the initial results and the anticipation of further data to guide the next phase of drilling. The Boa Vista project’s location within the prolific Tapajos Mineral Province adds geological appeal, with the deposit hosted in shear-zone controlled orogenic gold mineralisation.
Technical and Regulatory Considerations
The drilling program employs diamond core techniques with high sample recovery and rigorous quality control measures, ensuring reliable assay data. While the reported intercepts are downhole lengths and true widths are yet to be determined, the results provide a robust foundation for ongoing exploration. The project is subject to an earn-in agreement and various royalties, with no known impediments to further development at this stage.
Australian Mines continues to uphold responsible mining principles, emphasizing community engagement and environmental stewardship as it advances the Boa Vista Gold Project.
Bottom Line?
As Australian Mines awaits the remaining assay results, the Boa Vista project’s evolving data set could significantly influence its resource potential and strategic direction.
Questions in the middle?
- How will the pending assay results impact the overall mineralisation model at Boa Vista?
- What is the timeline for defining a maiden JORC-compliant resource based on the 2025 drilling?
- How might local regulatory and community factors influence the project’s development pace?
