Australia’s Most Successful Gold Explorer

We had the privilege of sitting down with legendary explorationist Ed Eshuys, widely credited with the Plutonic, Bronzewing and Jundee gold discoveries.

Ed takes us inside the second-last hole that lit up Bronzewing, how CSIRO’s laterite science helped crack Plutonic, why he drills diamond holes early to capture the third dimension, and the capital-strategy mindset that separates luck from repeatable success.

We also dig into St Barbara, Sons of Gwalia, the “surface vs shaft” decision, and the De Grey/Hemi sliding-doors moment (don’t stop your aircore 1–2 metres short!).

What we cover:

• The “go-for-broke” drilling philosophy—and why effective testing beats ‘busyness’

• CSIRO laterite nodules → Plutonic: from 1 g/t signs to 30 g/t and the first 30 holes

• Bronzewing’s 64th hole and stepping 200 m north to confirm discovery

• Jundee: proving scale along 8 km strike with wide-spaced diamond

• Capital is impatient: pairing funding with strategy so geology can win

• Surface vs shaft at Gwalia: $300/m looked crazy—until it was ~$30/oz added

• De Grey / Hemi: effective drilling, search lanes, and not stopping short

• Building mines, towns, and long-term value in WA vs sovereign risk abroad
