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.

When we talk about modern mineral discoveries in Australia, two names inevitably surface in the same breath: Prominent Hill and Carrapateena. Both sit in South Australia’s Gawler Craton, both are world-class Iron Oxide Copper-Gold (IOCG) systems, and both ended up becoming cornerstone assets for OZ Minerals, now part of BHP. But lumping them together as “IOCG discoveries” misses the deeper story.

Rumble Resources Limited (ASX: RTR) continues to advance the Western Queen Gold Project, located approximately 90 km northwest of Mt Magnet in Western Australia. The Company has released a Scoping Study for the Western Queen South deposit, outlining a technically simple, low-capital underground development that sits adjacent to multiple toll-treatment options within a 200 km radius. The Project is supported by a strong historical production record.
