As the Western world looks for non-Chinese supplies, Sky Metals has an abundance of both tin and tungsten at the Tallebung Project in New South Wales.

Guest bio Mr 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.

Key Insights

Tallebung is evolving into a dual-commodity development story. What was previously framed primarily as a tin project is increasingly being positioned around both tin and tungsten, with management indicating tungsten could contribute roughly half of future project revenue. That shift matters because Tallebung already reports tungsten in its mineral resource, and Sky says the existing flowsheet can recover both products with only a final dressing stage.

Tin’s supply-demand setup remains central to the investment case. Oliver Davies points to structural supply constraints and growing demand from electronics, data centres, solar technologies, and emerging battery applications as the core drivers behind stronger tin pricing. Sky’s broader corporate positioning is aligned with that thesis, describing tin as essential to semiconductors, electronics, and solar PV, which reinforces the strategic logic behind advancing Tallebung in New South Wales.

Tungsten adds strategic leverage to Western critical minerals supply chains. The episode highlights tungsten’s rising importance in defence and technology markets, particularly as Western buyers seek supply chains with less reliance on China. Sky’s own published Tallebung resource includes WO3 as a likely significant by-product, which gives investors exposure to a second critical mineral without fundamentally changing the project’s development pathway.

Tallebung’s open-pit, ore-sorting-led design points to a lower-cost development model. A key operational advantage discussed in the interview is the project’s shallow, open-pit geometry and the suitability of the mineralisation for XRT ore sorting followed by gravity separation. Sky states this approach can materially upgrade feed grade before concentration, supporting the company’s argument that Tallebung could become a near-term, low-cost tin development with added tungsten and silver credits.

Near-term catalysts are concentrated around resource growth and study work. The interview points to an updated mineral resource estimate and pre-feasibility study work as the main near-term newsflow, alongside ongoing drilling and metallurgical optimisation. That matches Sky’s stated project pathway of advancing drilling, resource confidence, metallurgical testing, and mining studies in parallel, giving the market several potential re-rating milestones rather than a single binary catalyst.

Great Western Exploration is preparing to launch a six-month drilling campaign targeting multiple copper-gold prospects near the legendary DeGrussa discovery in Western Australia.

Managing Director Shane Pike joins The Hole Truth to explain why the Yerrida Basin may host more DeGrussa-style volcanic massive sulphide deposits, and how Great Western has systematically built eight high-priority drill targets across its project portfolio.

With a market capitalisation of roughly $12 million and fresh capital raised, the company is highly leveraged to exploration success. Pike outlines the geological evidence supporting targets such as Oval, Diorama, Juggernaut and Baru, and explains why Great Western believes it may be closing in on the “CBD” — the core of a potentially mineralised system.

If successful, the program could reshape perceptions of the Yerrida Basin and demonstrate that DeGrussa is not a geological orphan.

Shane Pike is the Managing Director of Great Western Exploration Limited (ASX: GTE), a Western Australian mineral exploration company focused on copper, gold and base metal discoveries in the Yerrida Basin.

He has extensive experience in exploration geology and project development across Western Australia. Under his leadership, Great Western has assembled a portfolio of highly prospective tenements adjacent to the DeGrussa Copper-Gold Mine and is advancing systematic exploration programs targeting volcanic massive sulphide (VMS) deposits.

A Systematic Search for the Next DeGrussa Great Western Exploration is targeting DeGrussa-style volcanic massive sulphide (VMS) deposits in the Yerrida Basin of Western Australia. These deposits typically occur in clusters, yet the basin has seen surprisingly limited exploration specifically targeting this style of mineralisation. The company believes this represents a major geological opportunity.

Eight Drill Targets Across a Highly Prospective Basin The company has identified eight drill targets including Oval, Diorama, Juggernaut and Baru. Each target has been developed through a checklist-driven exploration process incorporating geological modelling, geophysics and geochemistry to confirm the key ingredients associated with VMS mineral systems.

Oval Target: Drilling the ‘CBD’ of the System Previous drilling at the Oval prospect intersected copper-gold mineralisation and pathfinder elements typical of VMS deposits. New gravity geophysics has identified a higher-density zone interpreted as the core of the system — effectively the “CBD” compared with earlier holes drilled in the “suburbs”.

Multiple Untested Copper Anomalies Targets such as Diorama and Juggernaut exhibit strong surface copper anomalies and favourable volcanic host rocks. Diorama hosts gossanous outcrops that may represent weathered massive sulphides, while Juggernaut contains multiple targets with visible mineralisation and VMS-style textures.

High Leverage Exploration with Tight Capital Discipline With a market capitalisation around $12 million, Great Western offers significant leverage to discovery success. More than 80% of company funds are directed into exploration, and non-executive directors receive no cash, shares or options for board roles—aligning management closely with exploration outcomes and shareholder returns.
