Maverick Springs Drills 102m at 86.2g/t Silver Equivalent, Boosting Resource Confidence
Sun Silver Limited reports robust drilling results from its Maverick Springs Project, revealing mineralisation grades surpassing existing resources and highlighting significant antimony presence. These findings bolster the project's strategic appeal amid a strong silver market and critical minerals focus.
- 102.1m at 86.2g/t silver equivalent including 50.6m at 149g/t AgEq
- High-grade antimony intercepts up to 9.3% Sb over 9.1m
- Drilling confirms and extends known mineralised zones
- Maverick Springs hosts 539Moz silver equivalent inferred resource
- Silver’s addition to US Critical Minerals List enhances project value
Strong Drilling Results Reinforce Maverick Springs Potential
Sun Silver Limited (ASX – SS1) has delivered encouraging assay results from its 2025 drilling campaign at the Maverick Springs Silver-Gold Project in Nevada, USA. The latest intercepts notably exceed the grades of the existing mineral resource, underscoring the project's growing scale and quality. Among the highlights is a thick mineralised intercept of 102.1 metres grading 86.2 grams per tonne silver equivalent (AgEq), including a higher-grade section of 50.6 metres at 149g/t AgEq. This robust silver-gold mineralisation confirms the project's strong fundamentals in a market where silver prices have surged above USD 100 per ounce.
Antimony Adds Strategic Dimension
Beyond silver and gold, the drilling has revealed significant antimony mineralisation, with zones grading up to 9.3% Sb over 9.1 metres. Antimony is increasingly recognised as a critical mineral, used in flame retardants and batteries, which adds a valuable strategic layer to Maverick Springs. This aligns well with recent developments, including silver’s inclusion on the 2025 U.S. Department of Interior Critical Minerals List, which is likely to attract further governmental and investor interest in projects like Sun Silver’s.
Geological Confidence and Resource Expansion
The drilling program has not only confirmed the predicted mineralised zones but also extended them, particularly with an intercept of 63 metres at 20g/t AgEq from 286 metres depth. These results reinforce the reliability of the current geological model and improve the understanding of mineralisation distribution. The deposit remains open along strike and at depth, suggesting further resource growth potential. Sun Silver’s Managing Director, Andrew Dornan, emphasised the significance of these findings, highlighting the thick, high-grade mineralisation and the strategic value added by antimony.
Project Location and Market Context
Maverick Springs is situated in Nevada, a top-ranked mining jurisdiction known for its prolific Carlin Trend, home to world-class gold and silver mines. The project’s inferred mineral resource currently stands at 237 million tonnes grading 45.5g/t silver and 0.30g/t gold, equating to 539 million ounces of silver equivalent. The strong performance of silver in 2025, coupled with its critical minerals status, enhances the project's appeal amid a tightening supply-demand balance globally.
Looking Ahead
Sun Silver plans to continue drilling to test shallow antimony targets, infill areas of interest, and extend mineralisation along the hinge zones. Metallurgical test work is ongoing to confirm recovery rates, which preliminary data suggests are promising for both silver and gold. These developments will be closely watched by investors and analysts as they could materially impact the project’s valuation and development pathway.
Bottom Line?
With high-grade silver, gold, and critical antimony mineralisation confirmed, Maverick Springs is poised for further growth amid a buoyant market.
Questions in the middle?
- How will upcoming metallurgical results impact resource economics and recovery assumptions?
- What is the potential scale of antimony mineralisation beyond current intercepts?
- How might silver’s critical minerals status influence funding and development timelines?
