Kalgoorlie-Boulder, Australia — March 2026
Topdrill has done it again — and this time, we’ve rewritten the global playbook. We’re ecstatic to announce that Topdrill has just set a new world record for the deepest Reverse Circulation (RC) drill hole, reaching an extraordinary 1,026 metres at the Benz Mining site in Western Australia.
This achievement doesn’t just break records — it redefines what’s possible in RC drilling and caps off an extraordinary milestone year as we celebrate 20 years of relentless innovation, capability and exploration excellence.
The Achievement
The new record-setting RC hole at the Benz Mining site pushes far beyond our recent Australian benchmark of 870 metres, which was itself a national standout performance in late 2025. That previous record showed the world what Topdrill is capable of — and now we’ve taken it even further.
To reach over a kilometre of continuous drilling in RC — with sample quality, operational precision, and efficiency intact — is an extraordinary engineering feat. This world record stands as a testament to the strength of our people, our equipment investments, and the precision behind every drilling plan.
Built by the Best
Reaching this depth wasn’t luck — it was engineered. Decades of experience, best-in-class downhole tooling, and elite crew execution came together to make this milestone a reality. Every hour drilled was planned, every rod run was intentional, and every sample returned counted toward better geological insight.
The 20-Year Context
This world record is more than a number — it’s a milestone in a two-decade journey that started with a small team and big ambition in Kalgoorlie. Now, with national reach and a reputation for pushing limits, Topdrill continues to drive technical performance and deliver outcomes that help clients go further, faster, and deeper.
A Shout-Out to the Team
We wouldn’t be here without:
- The rig crew and site support personnel who execute at the highest levels
- The engineering and planning teams whose precision makes milestones possible
- Our partners and clients, especially Benz Mining, who trust us on their most challenging programs
Next Up
Topdrill continues to explore depth potentials across our fleet, refine tooling strategies, and support clients pursuing frontier targets in Australia and beyond. This world record shows we’re just warming up.
Here’s to the next 20 years of pushing boundaries beneath the surface and setting new records above it!
