Great Boulder has restarted reverse circulation drilling at its Side Well gold project where previous drilling has returned multiple high-grade hits.

The drilling – part of its strategy to advance the Mulga Bill deposits towards a resource estimate as quickly as possible – will focus on the southern end of Mulga Bill, which while completely untested by RC drilling, has seen an exciting end-of-hole sample grading 23.78 grams per tonne (g/t) gold from aircore drilling in late 2021.

Great Boulder Resources (ASX:GBR) will also complete a second phase of RC drilling at the new Ironbark discovery to test the strike extent of recent high-grade intersections.

“I’m very happy to have Challenge Drilling back on site and on schedule, and also very excited to finally be drilling deeper holes into this southernmost target on the Mulga Bill – Loaded Dog trend,” managing director Andrew Paterson says.

“We’ll also complete a second round of RC drilling at Ironbark within the fortnight, where we are looking to test strike extensions and continuity of the high-grade gold mineralisation we intersected in our previous drilling.”

“We’re continuing to design more holes along the 6km extent of Mulga Bill to keep this rig on site for the remainder of the year and into 2023.

“This is an important phase of our exploration program for Side Well, and shareholders will now see a steady flow of updates through the rest of the year.”

Mulga Bill and Ironbark

While drilling at the southern end of Mulga Bill has extended the strike of the deposit to some 6km, the lack of deeper drilling presents the potential to find more mineralisation.

Achieving this objective will go a long way towards defining a substantial resource at the deposit.

Meanwhile, Ironbark is emerging as an exciting target in its own right given the bevy of strong gold intersections and mineralisation that remains open along strike.
