Unearthed

Show Notes

This episode was filmed on Wednesday 15th July and is part 1 of a 2 part series with Argor-Heraeus. In this episode of Unearthed, hosts John Reade and Joe Cavatoni are joined by Dr. Robin Kolvenbach, CEO of Argor-Heraeus a major precious metals refining company located in Mendrisio, Switzerland. Together they unpack the drivers behind the refining industry, often the least understood link in the gold value chain. Episode one dives into the economics of the refining industry, why a rising gold price is a cost and a risk to refiners, and how metal lease rates shape the business. In the conversation they cover sourcing patterns reshaped by downstream demand for responsible supply, the scale and significance of bar and coin demand, physically segregated production lines and the tracing processes that allows a gold bar to be identified with a phone years after it leaves the refinery.

Notable Quotes "I think what is important is you need overcapacity in a gold refinery because the inflow is not stable, but it has spikes." - Dr Robin Kolvenbach "We see an increased need for responsible sourcing on the downstream side, which changed our sourcing pattern in a way that we rather these days source from less risky jurisdictions than we might have done 20 years ago." - Dr Robin Kolvenbach "The other thing that's under appreciated by participants in the gold market is just how important bar and coin investments are." - John Reade "We need clarity around the ledger, without breaching any confidentiality around ownership or key data." - Joe Cavatoni

This episode was recorded on 15 October 2026. In this episode of Unearthed, hosts Joe Cavatoni and John Reade unpack why gold has been stuck in a holding pattern, with prices largely flat after a September pullback. With the U.S. midterm elections around the corner, they consider what the outcome could mean for gold, and why the answer may have less to do with party politics than investors might think. In the midst of conference season, they also turn to the topic dominating conversations on both sides of the Atlantic: central bank buying. After years of strong purchases and a sharply higher gold price, they ask what comes next for the sector, and what that could mean for the market in the years ahead.

Sep 8, 2026

This episode was recorded on Thursday 3rd September 2026. In this episode of Unearthed, hosts Joe Cavatoni and John Reade break down a volatile August for gold, with prices reaching highs of roughly $4,700 before correcting following hawkish comments from Kevin Warsh. They discuss the rally and how it looks narrower and more speculator-driven than the broad-based buying seen in late 2025/early 2026. They also touch on muted safe-haven demand despite ongoing Middle East tensions, as well as the Dutch National Bank's move to relocate gold from Ottawa and the US to London. Looking ahead, John and Joe flag the catalysts they're watching into September, from the FOMC meeting and incoming US data to signs of a broader physical demand recovery across China, India, and Southeast Asia.

Aug 20, 2026

This episode was recorded on 13 August 2026. In this episode of Unearthed, hosts Joe Cavatoni and John Reade unpack gold's push toward $4,400/oz, as softer US economic data clouds the outlook for further Fed rate hikes. They dig into a sharp pickup in ETF flows this month, continued central bank buying, and why the rally so far looks more tactical than broad-based — plus a surprisingly quiet seasonal demand out of China and India. Looking ahead, John and Joe flag the catalysts they're watching heading into the fall, from the Jackson Hole symposium to the U.S. November elections, and discuss what it would take to see the kind of retail enthusiasm that could take gold materially higher.

This episode was recorded on 25 February 2026. In this episode of Unearthed, hosts Joe Cavatoni and John Reade examine how scientific innovation is strengthening transparency across the global gold supply chain. They are joined by Dario Biedermann, Head of xTrace at aXedras, to discuss how origin verification technology uses geochemistry and machine learning to confirm where gold comes from. From X-ray fluorescence (XRF) analysis to deep neural networks that match elemental “fingerprints” to known sources, the episode explores how traceability can work in both refineries and upstream ASGM environments.

It’s not hypothetical anymore, we can implement it today.” – Dario Biedermann “You’ve got the hardware generating the data, but the real key is the software and the training model behind it.” – John Reade “In areas where traceability is paper-based, it’s very hard to prove where your material is actually from.” – Dario Biedermann “Traceability is becoming increasingly vital, not just for end users, but for governments and markets that need to understand these flows.” – Joe Cavatoni “We want to encourage sourcing, not systematically exclude certain areas—but be more granular and more precise.” – Dario Biedermann About World Gold Council We are a membership organisation that champions the role gold plays as a strategic asset, shaping the future of a responsible and accessible gold supply chain.
