Sun Silver Limited’s latest re-assay update from its Nevada project confirms broad antimony zones over 100m wide, with readings up to 1.7% Sb. These promising multi-commodity prospects enhance the silver-gold asset’s appeal for traders eyeing critical minerals.
Sun Silver Limited has released a comprehensive update regarding its Maverick Springs Silver-Gold Project in Nevada, USA. The company’s re-assay program, now testing historical drill core originally sampled for silver and gold, confirms the continued presence of antimony over wide zones. For instance, drill hole MR065 recorded a 66‐meter interval averaging 0.12% antimony, with a highlighted 1.5‐meter interval showing a grade of approximately 1.74% antimony. These results notably surpass the average antimony grades observed at comparable deposits, positioning the project as a potential significant U.S. source of this critical mineral.
The announcement details multi-element re-assays from historical holes including MR065, MR069, and MR098. The technical data shows extensive antimony intercepts, with some intervals from MR069 and MR098 providing additional layers of evidence for the mineralisation. The company has re-assayed about 30 historical holes with another 25 expected in the upcoming quarter, all conducted through modern methods such as four acid digestion with ICP-MS and gravimetric fire assay for high-grade silver results. This work adds to the project’s already robust JORC Inferred Mineral Resource estimate, which comprises 218 million tonnes grading 42.2g/t silver and 0.31g/t gold, highlighting the multi-commodity potential of the deposit.
The project is located in a premier mining jurisdiction in northeastern Nevada, situated near world-class operations and a well-established mining town. Sun Silver’s strategy to re-examine legacy data and apply contemporary analytical techniques is intended to further delineate the scale and grade distribution of antimony within the broader silver-gold system.
In terms of sentiment, the news offers a bullish outlook for the project. The discovery of extensive, high-grade antimony intervals reinforces the strategic significance of the Maverick Springs asset, particularly given antimony’s growing importance as a U.S. critical mineral. This technical progress and planned further assays may enhance investor confidence and open up additional value drivers for the company. On the bearish side, the complexity of reconciling historical data with modern assay techniques and dealing with missing sample intervals introduces an element of uncertainty that could delay the full realization of the deposit’s potential. Overall, the announcement signals both exciting opportunities and some ongoing technical challenges that investors will be watching closely.
