Expansion of the Merten Vein: A New Frontier for Blackrock Silver Corp.
Introduction
In a significant development for the mining sector, Blackrock Silver Corp. has announced the discovery of a 1,200-meter eastern extension of the high-grade Merten vein at their Tonopah West project located in Nye and Esmeralda Counties, Nevada. This discovery not only showcases promising assay results but also opens up new opportunities for resource expansion in an area rich in historical mining activity.
Scout Drilling Program Overview
The recent Scout Drilling Program yielded remarkable assay results from seven drill holes, expanding the mineralization footprint towards the historic Ohio mine. Notably, these promising new mineral zones fall outside the current DPB resource boundary and offer insights into the geological structure of the area.
Significant Findings
The highlighted discoveries include standout grades such as:
- 2,063 grams per tonne (g/t) silver equivalent (AgEq) from TW25-128, comprising 1,198 g/t silver (Ag) and 9.6 g/t gold (Au) over 1.52 meters.
- 952 g/t AgEq over 4.57 meters in TW25-133, showcasing 10.65 g/t Ag and 10.46 g/t Au.
These results demonstrate that the new zone of silver and gold mineralization aligns with the outer ring structure of the Fraction caldera, indicating potential for significant resource development.
The Expansion Program: Next Steps
In light of the successful scout drilling, Blackrock Silver is ramping up its efforts with a fully funded Expansion Program. This initiative employs innovative drilling techniques, including:
- One reverse circulation (RC) drill managed by Legacy Drilling.
- Two core drill rigs operated by Alloy Drilling.
The program aims to drill approximately 5,000 metres across 15 strategically selected holes targeting the newly identified Eastern Expansion zone. With drilling expected to conclude by October 2025, the findings are set to be incorporated into an updated Mineral Resource Estimate anticipated in Q1 2026.
Geological Insights and Implications
Blackrock’s exploration has unveiled that the Merten vein extends eastward, displaying a unique arching geometry that suggests multiple ring structures associated with the Fraction caldera. The discovery hints at a potential structural relationship with the historic Ohio vein, previously mined for its significant width of 15 meters in the early 1900s.
Detailed Assay Results
Table 1 provides a summary of the assay results for the Scout Drilling program, identifying intervals above 150 g/t AgEq. The variances in grades and intervals offer valuable insights into the mineral potential along the expanding Merten vein, adding to the overall optimism about the resource’s future viability.

Importance of Quality Control
Blackrock employs a rigorous quality assurance and quality control (QA/QC) process for sampling, ensuring that assay results are both accurate and reliable. Samples are handled securely, processed through certified labs, and monitored through a strict chain of custody from the field to the lab. Regular audits and checks are in place to maintain the integrity of the data.
Leadership and Strategic Vision
Blackrock Silver is helmed by Andrew Pollard, the President and CEO, whose insights emphasize the potential for significant mineral expansion at Tonopah West. The current drilling activities reflect the company’s proactive strategy and confidence in enhancing its mineral inventory.
