INSIGHTS FROM THE EPISODE

PolarX has secured a landmark farm-in agreement with Northern Star Resources (ASX: NST), giving Northern Star the right to earn up to 70% of the Alaska Range Project by spending $60 million. This partnership validates the project’s scale and potential.

The Caribou Dome deposit within the Alaska Range has delivered scoping study results showing an Internal Rate of Return (IRR) of ~70% (based on metals prices two years ago), underlining its strong economics and global significance as one of the highest-grade undeveloped copper projects in the USA.

PolarX controls an under-explored 35km mineralised corridor, including soil anomalies up to 11km by 8km in size. Northern Star’s backing allows for big-company exploration programs—geophysics, helicopter surveys, and systematic drilling—that were previously unaffordable for PolarX.

With copper recently added to the US Critical Minerals List, PolarX’s Alaskan copper-gold assets are strategically aligned with America’s push for secure, domestic supply. The jurisdictional advantage of being in the USA enhances the project’s attractiveness to global investors.

Outside the Alaska JV, PolarX retains full ownership of the Humboldt Range Project in Nevada, located next to major heap-leach gold and silver operations such as Florida Canyon and Rochester. Drill-ready and surrounded by multimillion-ounce deposits, Humboldt represents a second growth pillar for the company.

This week on The Hole Truth, we sit down with Sky Metals (ASX: SKY) to dig into the latest results from the Tallebung Tin Project in NSW. With standout silver and tin intercepts, breakthrough ore sorting results, and a pathway to becoming a globally significant tin producer, Sky is pushing hard to prove up scale and economics in one of Australia’s most exciting tin plays.

Managing Director Oliver Davies joined SKY as a geologist in 2019. He was appointed to Exploration Manager in 2021, then to CEO in early 2022 and subsequently to Managing Director in September 2024. Prior to SKY, Mr Davies was in exploration and operational roles with Evolution Mining and Alkane Resources in NSW and Qld. Mr Davies has worked closely on several successful NSW discoveries including Evolution Mining’s significant expansion of the Lake Cowal gold resource and with Alkane’s regional exploration success at Tomingley and Boda.

INSIGHTS FROM THE EPISODE

• Expanding Resource at Tallebung Tin– Sky Metals continues to grow its Tallebung deposit, now stretching over 2km long and 300–400m wide, with drilling pointing to significant extensions beyond the current resource.
• High-Grade Intercepts Boost Potential– Recent drilling returned standout results, including 3m at over 600g/t silver and nearly 1% tin, highlighting the project’s rich mineralisation.
• Ore Sorting Breakthrough– Bulk sample results show a 13x upgrade in ore sorting, a step change from earlier 3–4x upgrades, confirming Tallebung’s strong suitability for this cost-saving technology.
• Towards Long Mine Life and Scale– With ~23,000 tonnes of tin already defined and drilling density increasing, Sky is targeting a potential 10-year mine life and production that could represent ~1% of global tin supply.
• Strong Economics Backed by Leadership– Shallow high-grade zones offer potential for rapid payback on CapEx, while an experienced board led by Chairman Norm Seckold brings a track record of building successful mining projects.

Leeuwin Metals (ASX: LM1) are out to join those who believe that one man's trash can be another man's treasure in the WA gold exploration game.

INSIGHTS FROM THE EPISODE

1. Leeuwin Metals accelerates Marda Gold Project exploration Since acquiring the Marda Gold Project from Ramelius Resources just four months ago, Leeuwin Metals (ASX: LM1) has completed two drilling programs totalling 5,000m, extensive mapping, and new target generation across the Southern Cross Greenstone Belt in Western Australia.
2. Strong brownfields results confirm growth potential Drilling beneath existing pits at Marda has intersected significant gold zones, including 20m+ at 1–1.5g/t Au, 8m at ~3g/t Au, and 5m at 5g/t Au, demonstrating continuity at depth and substantial scope for resource growth.
3. High-grade opportunity at Evanston Prospect Leeuwin is preparing to drill the Evanston Prospect—a shallow, high-grade gold system last drilled over 20 years ago—where rock chip samples have returned assays up to 28g/t Au in quartz veins, with visible gold observed on site.
4. Dual growth strategy across 500km² of tenure With over 500km² of granted tenure, Leeuwin is pursuing a two-pronged approach: expanding known mineralisation around historical pits and advancing underexplored greenfields targets with potential for repeat high-grade discoveries.
5. Resource estimate expected by year-end An updated Mineral Resource Estimate for Marda—incorporating historic drilling and recent Leeuwin results—is on track for release by the end of 2025, a milestone that could significantly re-rate the company’s ~$15M market capitalisation.
