Humboldt Range Gold-Silver Project, Nevada

Humboldt Range Gold-Silver Project, Nevada
(100% PolarX owned)

The 100% owned Humboldt Range Project comprises 400 lode mining claims located in northwestern Nevada, USA, a recognised premier global mining jurisdiction and the source of ~75% of USA’s gold production.

Strategic Location

PolarX’s project is situated directly between two world-class, multi-million-ounce active operations:

• the 5Moz Florida Canyon gold mine and
• the 400Moz Rochester silver-gold mine.
• It also sits immediately adjacent to the 4Moz+ Spring Valley Gold Project which is currently under construction.

Access is excellent via existing roads off the I-80 Interstate Highway, located immediately to the west.

Target Footprint

The project encompasses two major claim groups tracking the economically proven Rochester Rhyolite host formation:

• Black Canyon (Gold Dominant): Located at the northern end of the range, sits within 3km of the Florida Canyon Gold Mine. It contains large coherent surface anomalies and historically mined high-grade veins.
• Fourth of July (Silver-Gold Dominant): Houses extensive outcropping quartz vein swarms, classic bonanza-style epithermal systems, and bulk-mineable potential.

Recent Exploration Highlights

• The Ridgeline Prospect: PolarX expanded this flagship system to a continuous 3.6km highly anomalous structural corridor. The anomaly is backed by intense Induced Polarisation (IP) chargeability.
• High-Grade Intercepts: Recent reverse-circulation (RC) drilling campaigns have confirmed substantial mineralised widths, returning standout assays such as 9.1m @ 6.38g/t gold (including 1.5m @ 37.29g/t Au).
• Massive Silver Halo: drilling unmasked an exceptionally wide silver geochemical footprint wrapping around the primary gold zones, validating the presence of a district-scale, deeply rooted epithermal gold-silver engine.

Development Strategy

Unlike traditional narrow-vein deposits, PolarX is targeting widespread, bulk-tonnage, open-pit heap-leach targets. This matches the highly profitable operating profiles of our immediate neighbours.

Continuous exploratory and definition drilling programs are planned across the Ridgeline, Black Canyon and Golden Staircase targets.
