Ridgeline Drilling Yields Up to 37g/t Gold Across Significant Widths

Initial Drilling Highlights Significant Gold Potential

PolarX Limited (ASX:PXX) has unveiled promising results from its first reverse circulation drilling campaign at the Ridgeline prospect, part of its Humboldt Range project in Nevada. The program, comprising 13 holes totalling just over 2,000 metres, intersected multiple wide zones of gold mineralisation starting from surface. Notably, assays revealed grades reaching as high as 37.29 grams per tonne (g/t) gold over 1.5 metres within broader intervals, including 16.8 metres at 0.55 g/t and 25.9 metres at 0.78 g/t gold.

A Large, Open Mineralised System

The Ridgeline anomaly extends over 3.6 kilometres, yet only 800 metres have been drilled to date, leaving substantial scope for expansion. The mineralisation is hosted within steeply dipping epithermal quartz veins embedded in rhyolite rock, a geological setting consistent with bonanza-style gold-silver deposits common in Nevada. The system remains open both along strike and at depth, with geophysical data suggesting the veins extend well beyond the current drilling depths of approximately 100 metres.

Strategic Location Amidst Established Mines

PolarX’s claims lie in a highly prospective corridor between major operating mines such as the Florida Canyon gold mine and the Rochester silver-gold mine. These nearby operations are large-scale, bulk-tonnage open-pit mines employing heap-leach processing, underscoring the commercial potential of mineralisation in the region. The Ridgeline prospect’s proximity to these mines, combined with the impressive assay results, positions PolarX well to advance its exploration ambitions.

Next Steps and Pending Assays

While the gold assay results are encouraging, silver assays from the same drill holes are still awaited and could further enhance the project’s value proposition. The company is preparing for a major follow-up drilling campaign scheduled to commence in mid-April, weather permitting, aiming to extend mineralisation both laterally and at depth. Additionally, PolarX is pursuing permits to test several historical high-grade veins nearby, which were mined in the early 20th century but remain largely unexplored by modern methods.

Operational Challenges and Quality Assurance

PolarX noted delays in assay reporting due to laboratory backlogs in Reno, Nevada, a challenge also faced by other exploration companies. The company has since ceased using the affected laboratory to avoid future delays. The drilling and sampling protocols adhere strictly to industry standards, with quality control measures including certified reference materials and duplicate samples to ensure data reliability.

Broader Implications for Humboldt Range

The results at Ridgeline complement previous drilling successes at PolarX’s Star Canyon prospect, collectively demonstrating a sizeable mineralised footprint within the Black Canyon project area. The ongoing exploration efforts at Humboldt Range could unlock a significant new gold-silver resource in a well-established mining district, attracting further investor interest and potentially reshaping the company’s growth trajectory.
