Great Boulder Resources (ASX: GBR) has hit multiple high-grade intersections with grades up to 194.50g/t Au from infill and extensional RC drilling at the Mulga Bill target in WA.
Mulga Bill is part of the company’s flagship Side Well Gold Project near Meekatharra which hosts a Mineral Resource Estimate (MRE) of 668,000oz @ 2.8 g/t Au.
“These are sensational new intersections at Mulga Bill. The holes were designed to add definition within areas of inferred resource and they have done so in emphatic style, with intersections that are both thicker and higher grade than previously estimated,” Managing Director, Andrew Paterson, said.
“Equally impressive is the deep result in hole 24MBRC030 which is well outside the resource, down- dip and further north than previous drilling in that area.”
“After several rounds of drilling at Mulga Bill the high-grade lode positions fit our interpretation perfectly, which means we have very high confidence in the validity of this resource model.
“The drilling has added high-grade intersections up-dip from previous holes on several sections within the resource, which should add gold ounces closer to surface than the current estimate. This will be important for potential mine economics when we start scoping studies.”
Nine RC holes were drilled at Mulga Bill for a total of 1,587m. The programme was designed to test poorly defined areas around the edges of the Mulga Bill high-grade vein positions as part of the process to upgrade less-drilled parts of the resource from inferred to indicated category.
Next Steps
The RC rig is currently drilling the final resource definition RC holes at Mulga Bill, after which reconnaissance AC drilling will commence on exciting new targets at Side Well South.
The two deep diamond holes recently drilled at Mulga Bill were logged, cut and sampled in mid- September and all samples have now been submitted to the assay lab. Results for these are expected during October.
Resource definition RC drilling will also be completed at Saltbush during October. This work will be scheduled in conjunction with the Side Well South AC programme.
