Sierra Nevada Gold Inc. reports promising tailings sampling at its New Pass Project in Nevada, with results reaching up to 4.09g/t gold. The encouraging data is driving plans to explore processing options and restart underground mining, offering exciting prospects for efficient gold recovery.
Sierra Nevada Gold Inc has reported encouraging results from its recent auger sampling program at the New Pass Project in Nevada, USA. In May 2025, the company drilled 66 six‐inch diameter auger holes to a maximum depth of 2 meters in four historic tailings dams. Across 113 one‐meter interval samples, an average grade of 1.55 grams per tonne (g/t) of gold was recorded. Notably, Tailings Dam 1 produced an average grade of 1.87g/t over 49 samples, while Tailings Dam 3 averaged 1.51g/t over 37 samples—with individual assays reaching up to 4.09g/t gold—indicating that coarse gold particles further support a case for reprocessing the material.
The detailed auger drilling involved taking more than 10 kilograms per interval using industry-standard sample splitting and fire assay analysis. Historical mining at New Pass, with reported average grades of 17g/t in the past, reinforces the confidence that residual tailings may still harbor economically viable gold mineralisation. Additionally, exploration on the Superior Vein, where previous drilling returned 1.22 meters at 26.7g/t gold, underpins the company’s plans for conducting bulk ore sampling and advancing underground mining operations. Sierra Nevada Gold Inc is presently progressing on permits to reopen the Superior Mine and is actively designing drill positions and planning further drilling once regulatory approvals are in place.
Positive interpretation of the results highlights several technical strengths: consistent sample recoveries, promising gold grades from multiple tailings dams, and indications of coarse gold that suggest historic grinding methods may have underestimated the resource. On the bullish side, these factors support the potential for reprocessing the tailings to generate new revenue streams and may boost investor confidence in reinstating gold production at New Pass. Additionally, the company’s historical production record and ongoing efforts to secure mining permits add to an optimistic outlook.
Conversely, a more cautious perspective notes that these findings are preliminary exploratory results and the project is still in its early stages. Challenges remain in scaling up reprocessing operations, and future bulk sampling and additional drilling will be necessary to fully define the continuity of the high-grade mineralisation. Permitting and regulatory approvals also introduce an element of uncertainty, potentially tempering near-term enthusiasm among investors.
Overall, the announcement from Sierra Nevada Gold Inc provides technical evidence of promising gold grades in historic tailings and reinforces strategic plans for further exploration and underground mining. Investors considering exposure to early-stage mining prospects may view these developments as a forward-looking signal, while mindful of the inherent risks associated with mining project development.
