Great Boulder reckons shallow, high-grade gold at Ironbark has open pit potential

Great Boulder Resources (ASX:GBR) MD Andrew Paterson says the company’s Ironbark discovery at the Side Well Gold Project in WA is looking “increasingly exciting” off the back of recent RC drilling intersecting high-grade, shallow gold.
“Ironbark is looking increasingly exciting, with thick high-grade mineralisation extending close to surface and some really solid high-grade zones in the fresh rock,” he said.
Best results from the drilling included:
And re-split assays from 4m composites sampled in the Phase 1 RC program at the project have refined the high-grade intersections, including:
Assays are pending for the remaining drill holes, and RC drilling is ongoing at Mulga Bill.
“The significance of these new results is that they support our early impression Ironbark may have potential for open pit mining, with ounces close to surface,” Paterson said.
“Ironbark could be a game-changer for Side Well in the sense that near-surface ounces have potential to make a future mining scenario more attractive.
“I am very keen to see the assay results from the remaining holes in this phase of drilling.
“We don’t yet know whether Ironbark has been closed off along strike, and it is definitely open at depth.”
Metallurgical test work is underway with final results expected in around two months.
“We have already commissioned a round of metallurgical testing on Ironbark samples,” Paterson says.
“The test-work will look at gravity recoveries, grind size optimisation and total recovery using cyanide, similar to the test-work we completed recently at Mulga Bill.”
RC drilling is progressing on the Mulga Bill corridor, and a program of works (PoW) approval has now been lodged for a third round of RC drilling at Ironbark.
Once all Phase 2 assays have been received, the company will reassess priorities at Side Well, with an option to accelerate drilling at Ironbark to move towards a maiden Mineral Resource Estimate in the medium term.
