    #132 - Graham Kerr (South32): Building a Mining Career Without a Mining Degree

    In this episode of Sweat Capital, we sit down with Graham Kerr, CEO of South32, for a rare, career-focused look at leadership, capital allocation, and what it actually takes to succeed in mining.  Graham’s path defies the stereotype. He didn’t study mining engineering — instead, he began with business, finance, and information systems before joining BHP as a graduate. By going all-in on learning, pushing beyond head-office finance roles, and taking on operational responsibility early, he progressed from analyst to CFO to CEO.  We unpack his time at BHP, including what working inside one of the world’s largest resource companies taught him about capital allocation, scale, and optionality. Graham shares how moving into site-based and operational roles reshaped his leadership style — and why leaving the “safe path” at key moments proved critical to long-term growth.  A major focus of the conversation is the BHP–South32 demerger and what it takes to build a company from day one. Graham reflects on creating culture from scratch, leading assets others didn’t want, making hard portfolio decisions, and why discipline — not size — defined South32’s strategy over the next decade.  If you’re interested in leadership, mining, or how real careers are built inside complex organisations, this episode is a masterclass in learning fast, owning responsibility, and playing the long game.  ***This episode was recorded on 14 January 2026 at the Future Minerals Forum in Riyadh, Saudi Arabia.

    #130 - Armina Rosenberg (Minotaur Capital): How Technology Is Changing Stock Picking

    In this episode of Sweat Capital, we sit down with Armina Rosenberg, Co-Founder and Portfolio Manager at Minotaur Capital, to unpack how she actually finds investment ideas across every major market in the world.  We trace Armina’s path from equity research at J.P. Morgan, through the family office world, to running global equities portfolios — and why covering the entire universe of listed companies forces you to think very differently about process, diversification, and speed.  A major focus of the conversation is Taurient, the proprietary software Minotaur built in-house to screen, analyse, and compare companies globally. Powered by Python and AI, Taurient allows the team to translate overseas annual reports and transcripts, scan thousands of companies across markets, and surface opportunities most investors will never see.  We also discuss:  The trade-offs between institutional investing, family offices, and running your own fund  How technology changes portfolio construction and risk management  Why global diversification matters more than ever  What Armina looks for when hiring analysts in a tech-enabled investment team  If you’re interested in global equities, active management, or how modern fund managers actually build an edge, this episode is a masterclass in process over prediction.  *** This episode was recorded on 3 February 2026.

    #126 - Rob Adamson (RFC Ambrian): Why Most Mining Tech Fails (The Blueprint for Turning Science Into Scale)

    This episode was recorded OnAir @ IMARC. For more information on the world's biggest mining conference and how to get involved, visit ⁠⁠⁠imarcglobal.com⁠⁠⁠. In this episode of Sweat Capital, we’re joined by Rob Adamson, Executive Chairman at RFC Ambrian, for a wide-ranging conversation across mining, deep tech, and career-building. Rob takes us back to his first job as a 16-year-old on a diamond drill rig in Central Western Australia – and how brutal summers in the mines became the motivation to study engineering, fund uni through holiday shifts, and eventually take a leap overseas to deep-level underground gold mining in South Africa at the back end of apartheid. From there, we unpack how Rob found his way into advisory, why RFC’s model is different to “spray and pray” venture capital, and how a disciplined venture-building approach helped bring game-changing technologies to market –including Chrysos (a modern alternative to fire assay), NextOre (MRI-style sensing for real-time ore grade detection), and MRead, where detection technology can identify landmines by sensing explosive compounds. We finish with Rob’s practical advice for young professionals: build your skillset, build your network, and most importantly – build your own brand. Follow Sweat Capital on Instagram & LinkedIn. We’ll see you in the next one, Keep playing the long game.
