MR25-230 Drill Hole Yields 71g/t Silver Equivalent Over 140m in Nevada
Sun Silver Limited’s latest drilling at Maverick Springs in Nevada reveals a substantial 140m mineralised interval above the current resource, highlighting the project’s expanding potential for silver, gold, and antimony.
- Drill hole MR25-230 intercepts 140m at 71g/t silver equivalent above existing resource
- Includes 39m at 151g/t silver equivalent with significant gold grades
- Extensive antimony mineralisation over 79m within the same zone
- Supports Maverick Springs as a district-scale precious metals deposit
- Project hosts a JORC Inferred Resource of 218Mt grading 42.2g/t Ag and 0.31g/t Au
Drilling Breakthrough at Maverick Springs
Sun Silver Limited (ASX – SS1) has announced compelling assay results from drill hole MR25-230 at its flagship Maverick Springs Silver-Gold Project in Nevada, USA. The hole intersected a remarkable 140.21 metres of mineralisation starting 26 metres above the previously defined Mineral Resource, underscoring the continuity and scale of the deposit.
The mineralised interval returned an impressive average grade of 71 grams per tonne silver equivalent (AgEq), which includes a higher-grade section of 39.08 metres at 151g/t AgEq. Notably, this intercept also contains a significant gold zone of 5.3 metres grading 3.65g/t Au, adding valuable diversity to the precious metals profile.
Antimony Adds Strategic Value
Beyond silver and gold, the drilling revealed extensive antimony mineralisation, with cumulative zones spanning over 79 metres. Antimony grades reached up to 871 parts per million (ppm) in broad intervals, with narrower zones exceeding 3,000 ppm. This element, often overlooked, can enhance the economic potential of the project given its industrial applications.
Sun Silver’s Managing Director Andrew Dornan highlighted the significance of these results, stating that intercepting mineralisation above the current resource boundary confirms Maverick Springs’ status as a world-class, district-scale precious metals deposit. The results also validate the company’s ongoing exploration strategy focused on resource expansion and infill drilling.
Project Context and Future Prospects
The Maverick Springs Project is strategically located near the prolific Carlin Trend, a globally renowned gold and silver mining district. The project currently holds a JORC Inferred Mineral Resource of 218 million tonnes grading 42.2g/t silver and 0.31g/t gold, equating to approximately 296.5 million ounces of silver and 2.2 million ounces of gold.
Importantly, the deposit remains open along strike and at depth, with multiple mineralised intercepts outside the current resource model. The recent drilling results, combined with ongoing metallurgical test work, suggest potential for both resource growth and improved recovery rates.
Sun Silver continues to advance its 2025 exploration program, with plans for further drilling targeting shallow antimony, silver, and gold zones, as well as extensions to the northwest and south of existing drill areas. Metallurgical sampling is also underway to refine processing parameters.
Technical and Regulatory Assurance
The company’s exploration and assay protocols adhere to industry best practices, including rigorous quality control measures and compliance with the JORC Code. Independent geologists have verified the results, and the company maintains transparency in reporting, with detailed assay data and geological interpretations made publicly available.
Bottom Line?
Sun Silver’s latest drilling success at Maverick Springs sets the stage for a potential resource upgrade and further exploration breakthroughs.
Questions in the middle?
- How will these new mineralised zones impact the upcoming resource estimate revision?
- What are the implications of the significant antimony mineralisation for project economics?
- How might ongoing metallurgical test results influence future processing strategies?
