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.

Great Boulder Resources has just unveiled a whopping 4,434g/t gold assay at its Side Well Gold Project in Western Australia. The company already has a 1 million ounce resource and has outlined a plan to increase this to 1.5 million ounces, located right on the edge of three processing plants.

Andrew Paterson is the Managing Director of Great Boulder Resources. He is a geologist with more than 25 years of experience in the mining industry, spanning exploration, resource development and project generation across Australia and internationally. Prior to joining Great Boulder, he held senior roles with several exploration and mining companies where he was responsible for discovery and advancement of gold projects in Western Australia. At Great Boulder, he is leading the company’s exploration and development strategy at the Side Well Gold Project near Meekatharra.

1. Exceptional High-Grade Assay Highlights Depth Potential Great Boulder recently reported an extraordinary 4,434g/t gold intercept at the Side Well Gold Project, one of the highest-grade hits recorded in the industry this year. While extremely high-grade zones are typically small, they demonstrate the presence of rich gold-bearing structures at depth and reinforce the potential for continued discovery beneath the existing resource. These “bonanza” zones occur in structural dilation points where coarse gold accumulates.

2. A 2.5km Resource Corridor With Potential to Become a Regional Super Pit The current resource extends across approximately 2.5 kilometres of strike between the Mulga Bill and Eaglehawk deposits. With only a narrow gap of limited drilling between the two areas, upcoming drilling programs aim to confirm continuity that could effectively link the deposits into a single large open pit system. At current gold prices, conceptual pit optimisations already suggest a large combined mining footprint.

3. Targeting Growth From 1Moz to 1.5Moz Resource Great Boulder currently hosts a 1 million ounce resource at Side Well, with roughly 62% in the indicated category. The company’s next strategic objective is to increase the total resource to around 1.5 million ounces, which could translate to roughly 1 million ounces of mineable inventory after studies and conversions. Achieving that scale would significantly enhance development and partnership options.

4. Strategic Location Near Multiple Processing Mills A major advantage for the project is its proximity to several operating or proposed processing facilities in the Meekatharra region. Within trucking distance are three potential mills, including Westgold’s Bluebird facility only about 25km away. This infrastructure access creates multiple potential development pathways, including toll treatment or acquisition interest from nearby operators seeking additional feedstock.

5. Accelerated Drilling and Development Pathway Underway Great Boulder is ramping up exploration with multiple drilling rigs targeting both resource expansion and new discoveries around the existing corridor. The company is simultaneously advancing mining leases, approvals and development studies to shorten the timeline from exploration success to production readiness. As resource growth and permitting progress in parallel, the project could become increasingly attractive to strategic partners or regional consolidators.
