Great Boulder Resources (ASX: GBR) has obtained high-grade assay results from the first phase of RC drilling at the Ironbark prospect, within the Side Well Gold Project near Meekatharra in Western Australia.
Highlights
- High-grade gold intersected in the first RC drilling for the year at Ironbark include: 20m @9.41g/t Au from 111m, including 5m @17.47g/t Au from 125m in 23IBRC007; 8m @9.89g/t Au from 115m, including 1m @72.60g/t Au from 117m in 23IBRC004; and 14m @3.61g/t Au from 82m, including 9m @5.49g/t Au from 82m in 23IBRC003.
- RC hole 23IBRC001 has extended the strike of Ironbark north by 50m.
The programme was designed to extend the Ironbark mineral resource (87koz @2.9 g/t Au within a broader Side Well Inferred MRE of 518koz @2.6 g/t Au) down dip and along strike to the north, as well as infilling previous drilling on some sections
Further RC holes will be planned for the next phase of drilling at Ironbark
RC drilling at Mulga Bill is ongoing and an AC drill programme has commenced testing high priority regional targets along the +6km Mulga Bill corridor.
“This is a great start to the year, with our first RC hole at Ironbark extending the strike north by 50m and a number of thick, high-grade intersections adding ounces at depth,” Managing Director, Andrew Paterson, said.
“The northern-most intersection has defined a wide zone of mineralization; 31m down-hole including a higher-grade portion of 6.0m averaging 8.10g/t Au. This result is a significant increase to the mineralized envelope which adds to our expectation that Ironbark has excellent potential for open pit mining.
“The other intersections in this round of drilling add high-grade ounces at depth. This small programme of RC drilling has added a lot of value.
“With these results and the recent stellar assays from Mulga Bill the GBR team is off to a fantastic start to 2023, and I’m looking forward to more assays flowing through in the next few weeks.”
The 2023 Phase 1 RC programme at Ironbark comprised nine holes for 1,254m. Holes were designed to extend mineralization down dip and along strike to the north, as well as infilling previous drilling on some sections. While assaying is complete for most of the programme a small number of results are still being processed for hole 23IBRC002.
Next Steps
RC drilling is continuing at Mulga Bill, with the current campaign expected to be completed shortly. Assuming a four-week assay turnaround, results from this drilling are expected to arrive in batches over the coming month.
A programme of AC drilling is now underway testing a range of areas within the six km Mulga Bill corridor, including the Flagpole and Loaded Dog prospects as well as interpreted structural targets northeast of Mulga Bill.
