65m Antimony Zone with 7.8% Sb Confirmed in Historic Drillhole MR127 at Maverick Springs
Sun Silver Limited reports significant antimony mineralisation in historic drillhole MR127 at its Maverick Springs Project, reinforcing plans for a maiden antimony resource alongside its established silver-gold system.
- 65m total antimony zone with grades up to 7.8% Sb in drillhole MR127
- Ongoing multi-element re-assay program on historic samples
- Potential maiden antimony Mineral Resource estimate underway
- Maverick Springs hosts a large inferred silver-gold resource
- Project located near Nevada’s prolific Carlin Trend mining district
Historic Drilling Reveals New Antimony Potential
Sun Silver Limited has announced compelling new assay results from its Maverick Springs Silver-Gold Project in Nevada, USA. The highlight comes from historic diamond drillhole MR127, which returned a substantial 65-metre zone of antimony mineralisation, with grades reaching as high as 7.8% Sb. This discovery emerges from an ongoing multi-element re-assay program targeting legacy drill samples originally assayed only for silver and gold.
Expanding the Project’s Multi-Commodity Profile
The re-assay program, conducted by American Assay Laboratories, is part of Sun Silver’s broader strategy to unlock additional value from the Maverick Springs Project by defining antimony mineralisation alongside its well-established silver and gold resources. The company is advancing towards a maiden antimony Mineral Resource estimate, which would complement the existing inferred resource of 218 million tonnes grading 42.2 grams per tonne silver and 0.31 grams per tonne gold.
Strategic Location and Geological Context
Located approximately 85 kilometres from Elko, Nevada, and adjacent to world-class operations such as Barrick’s Carlin Mine, Maverick Springs benefits from being in the top-ranked mining jurisdiction globally. The deposit’s geological setting is complex, with mineralisation hosted in Permian sedimentary rocks and showing characteristics of both Carlin-type and epithermal styles. The discovery of significant antimony zones adds a new dimension to the project’s potential.
Next Steps and Market Implications
Sun Silver is continuing to assay over 35 historic drill holes and plans validation drilling to better understand the controls on antimony mineralisation. Further assay results are expected throughout the third quarter of 2025. If the maiden antimony resource is confirmed, it could enhance the project’s economic profile by adding a critical mineral component increasingly sought after in global markets.
Bottom Line?
Sun Silver’s expanding antimony footprint at Maverick Springs could redefine the project’s value proposition in a critical minerals era.
Questions in the middle?
- How will the maiden antimony resource integrate with the existing silver-gold resource in terms of mining and processing?
- What are the potential economic impacts of antimony inclusion on project development timelines and capital requirements?
- How might evolving market demand for antimony influence Sun Silver’s strategic priorities at Maverick Springs?
