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.

In this episode of Coffee with Samso, I sat down with John Anderson, the geologist most closely associated with the discovery of the Paris Silver Deposit on South Australia’s Eyre Peninsula. John is not just another explorer who drilled a successful hole. He represents a generation of geologists who built discoveries through persistence, pattern recognition, and the willingness to challenge accepted geological thinking.

In this episode of Coffee with Samso, Noel Ong speaks with the team from PTR Minerals Limited about the discovery of the Rosewood Titanium Deposit at the Muckanippie Project in South Australia.

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.
