Great Boulder Resources’ (ASX: GBR) RC drilling at Mulga Bill North has identified broad zones of gold mineralization up to 1.25km north of the currently defined 518koz Au Mineral Resource Estimate at the Side Well Gold Project in Western Australia.
“Our Phase 2 RC programme included holes at Ironbark, Mulga Bill North, Mulga Bill, Flagpole and the eastern target at Mulga Bill which we have named Cervelo. The name is taken from a bicycle theme, after Mulga Bill’s bicycle,” Managing Director, Andrew Paterson, said.
“We’ve always known the gold mineralization at Mulga Bill remained open to the north, but to date there has been very limited drilling in that area. These new results at Mulga Bill North highlight the potential more than one km north of the current resource.
“We are waiting on assays for the final six RC holes from this program. We now have a diamond drill rig on site drilling six holes at Ironbark and Mulga Bill for structural information. Drilling should take three to four weeks, after which we’re planning further AC and RC programmes.”
Assay results have now been received for the first 29 RC holes completed in the second phase of 2023 RC drilling at Side Well. The company has also received assays for the final 19 holes drilled during the AC programme completed in April.
The Phase 2 RC drilling program comprised a total of 35 holes for 6,134m. This programme comprised nine holes at Ironbark, seven holes at Flagpole, seven holes at Mulga Bill, 6 holes at Mulga Bill North and 6 holes at Cervelo.
The company is waiting on assays for the last eight holes drilled in this programme.
Of the six holes drilled at Mulga Bill North several holes intersected broad zones of anomalous gold mineralization associated with the Mulga Bill pathfinder elements bismuth, silver and, in some cases, copper. As the company assays approximately one sample in 25 for multi-element analysis it is remarkable that four of the six holes returned strongly anomalous bismuth results.
This drilling combined with previous RC and AC drilling has now defined a NE striking Au-Cu-Ag-Bi trend over 700m that remains open. The grade distribution and interpreted geometry of this lode strongly resembles Mulga Bill in its early phases of exploration.
Weathering within this zone is particularly deep, with some RC holes finishing within saprolite at 150m. Gold mineralization is hosted within a supergene blanket and relict quartz veins and lode structures that have partially survived weathering processes.
