Highlights

  • Great Boulder Resources advances exploration at Side Well.
  • Multiple deposits under focus including Ironbark, Eaglehawk, and Mulga Bill.
  • Extensive drilling programs to strengthen resource definition.

Expanding Side Well Gold Project

Great Boulder Resources (ASX:GBR) continues to strengthen its exploration footprint at the Side Well Gold Project near Meekatharra in Western Australia. With ongoing fieldwork across key deposits, the company is pursuing an ambitious strategy that reflects the momentum seen across the broader ASX 200 index.

The current program focuses on new gold targets identified within the central and eastern corridors, supported by detailed aircore drilling. These areas have shown potential with strong anomalies that extend across multiple trends.

Focus on Ironbark and Eaglehawk

The company is moving its reverse circulation drilling from Side Well South to Ironbark, concentrating on resource definition at the deposit. Following this phase, the program will extend to the Eaglehawk deposit to further examine promising zones. Previous results from these sites have indicated the continuation of mineralisation at depth, making them significant priorities in the current exploration cycle.

Diamond drilling is also planned at Mulga Bill and Eaglehawk later in the year. This phase is expected to provide additional insights into the stacked vein systems while also contributing important geotechnical and metallurgical information.

Advancing Toward Growth

Great Boulder has outlined a clear strategy that aims to expand the scale of the Side Well Gold Project. The company has already identified several deposits including Mulga Bill, Eaglehawk, Ironbark, Saltbush, and Side Well South. Together, these areas represent the foundation for future resource growth and potential development.

Over the years, Great Boulder has completed extensive aircore, reverse circulation, and diamond drilling across the project. This has resulted in significant progress in outlining mineralised corridors, including the eastern corridor which spans a large strike zone and is considered highly prospective.

Outlook for Side Well

With multiple drilling programs running in parallel, Great Boulder remains committed to accelerating exploration across Side Well. Each phase of drilling is designed to build a stronger understanding of the mineral system while contributing to resource growth across the project.

The company’s long-term vision focuses on adding scale and value through systematic drilling, targeting both new discoveries and resource definition across its established deposits.
