The Copper Is Hiding in the Minerals, Not the Assays — CSIRO's Tobias Schlegel on IOCG Vectoring
Coffee with Samso
Coffee with Samso — with Dr Tobias Schlegel, Senior Research Scientist, CSIRO We're back at Samso HQ at the University Club, on the UWA campus in Crawley, and this is a conversation that has been a few years in the making. I first came across Tobias Schlegel at an IOCG workshop in Adelaide. He was up the front talking about how these deposits actually form, and I remember thinking, I need to talk to that guy. It has taken two or three years, but here we are. Tobias is a Senior Research Scientist at CSIRO, where he has spent close to seven years, and he has been working on Iron Oxide Copper...

The Discovery of the Challenger Gold Mine – Gawler Craton, South Australia
Coffee with Samso
There are discoveries that change a region's prospectivity forever. The Challenger Gold Mine in the Gawler Craton is one of them. In this episode of Coffee with Samso, I sat down with David Edgecombe, the geologist who was instrumental in the discovery of the Challenger Gold Deposit in outback South Australia. David is not simply a man who happened to drill a good hole. He is a geologist's geologist — one who understood the rocks, trusted the science, and applied a methodology that was, at the time, genuinely groundbreaking in this part of the world. At 1.2 million ounces of gold,...

Coffee with Samso
Coffee with Samso - Episode 220 | Kaiser Reef Limited (ASX: KAU) | The University Club | Crawley | Western Australia There are moments in the ASX mining space where a transaction changes everything for a company. This Coffee with Samso conversation with Brad Valiukas from Kaiser Reef Limited is one of those moments. Filmed back at Samso HQ at the University of Western Australia, this discussion centres on what I described as an “overnight producer” story—driven by the acquisition of the Henty Gold Mine. And in many ways, that label fits. The “Overnight Producer” – What...

Guest: Michael Beven – CEO, Pioneer Minerals Limited (ASX: PMM)
Introduction
In this episode of Coffee with Samso, I sat down with Michael Beven, CEO of Pioneer Minerals Limited (ASX: PMM), in the heart of Adelaide, to unpack what is shaping up as one of the more technically compelling US critical minerals exploration stories currently flying under the radar.
The discussion focused on tungsten, antimony, and gold, but more importantly, on mineral systems thinking—how deposits form, why certain geological settings matter, and why Pioneer’s ground selection in Idaho, USA, was anything but random. As someone who has followed tungsten closely, this was a conversation that went well beyond commodity hype and into the fundamentals of discovery.
This Coffee with Samso episode is about process, geology, and long-term thinking, not short-term market noise.
The Business of the Company: Focus – US Critical Minerals Projects
Pioneer Minerals Limited is focused on advancing critical minerals exploration in the United States, aligned with US strategic supply-chain priorities.
-
North Pine Project, Idaho – A multi-prospect project (Springfield, Silver Cliffs, Northman) targeting tungsten and antimony, with additional gold and silver mineralisation.
-
Proven mineral systems – High-grade surface results confirm tungsten skarns and precious-metal vein and epithermal-style systems.
-
Strategic location – Located near major regional projects and a nearby tungsten–antimony processing facility, providing potential development leverage.
Pioneer’s strategy is to advance North Pine through systematic, data-driven exploration in a Tier-One jurisdiction.
About the Projects
North Pine Project, Idaho
-
Located in mining-friendly Idaho, USA, within a well-endowed tungsten–antimony district.
-
Comprises the Springfield, Silver Cliffs, and Northman prospects over ~34 km².
-
Targets US-designated critical minerals — tungsten and antimony — with additional gold and silver upside.
Springfield & Silver Cliffs Prospects
-
Springfield hosts a high-grade scheelite tungsten skarn and a separate gold–silver–antimony vein system.
-
Silver Cliffs shows epithermal-style gold–silver–antimony mineralisation and is located near an existing tungsten–antimony processing facility.
Funding, Structure, and Long-Term Intent
Pioneer Minerals is tightly held, with strong cornerstone shareholders who backed the pivot into US critical minerals from the outset. The company has already committed significant capital to ground acquisition and early exploration, signalling intent rather than opportunism.
Importantly, this is not a story built around chasing what is currently fashionable. As Michael put it, if the goal were short-term rerating, antimony alone would be the headline. Instead, the focus remains on building a long-life tungsten system, with gold providing additional upside.
Tungsten: Rare, Strategic, and Misunderstood
A major theme of the discussion was the disconnect between tungsten price and market awareness. Tungsten prices have moved sharply higher, yet investor understanding lags behind antimony and even rare earths.
Michael made several key points:
-
Tungsten deposits are genuinely rare, not just economically rare
-
Global Tier-1 tungsten deposits are small by tonnage compared to copper or gold
-
China controls ~83% of global supply and processing
-
There is no operating tungsten mine in the US
The implication is clear: tungsten sits at the intersection of rarity, defence, and industrial necessity, with a supply chain vulnerability that the market has not yet fully priced in
Why This Coffee with Samso Matters
This conversation is a reminder of why geology still matters.
In a market often driven by themes and headlines, Pioneer Minerals is taking a bottom-up approach—starting with mineral systems, historical context, and geological logic. Whether or not Springfield becomes the next Yellow Pine remains to be seen, but the thinking behind the project selection is sound.
For investors who value process over promotion, this Coffee with Samso episode offers a clear window into how real exploration decisions are made.
In the words of Samso, get your favourite beverage and sit and listen to another great insight from Coffee with Samso.
