Highlights

  • New targets identified through geophysical surveys
  • Second drill rig to accelerate exploration efforts
  • Further design work underway at Ironbark pit

Great Boulder Resources (ASX:GBR) is advancing its exploration at the Side Well Gold Project in Western Australia, with plans to deploy a second drill rig later this month. This move follows the identification of multiple new targets during recent geophysical surveys, enabling the company to ramp up current drilling programs while initiating first-pass drilling on fresh prospects.

The induced polarisation survey highlighted chargeability anomalies across a substantial strike length north of the Mulga Bill deposit, including at the Eaglehawk prospect. Additionally, a new target corridor has been outlined between Mulga Bill and Ironbark, marked by coinciding chargeability and density indicators.

Strategic Drilling and Studies in Motion

Current activities include resource definition drilling at Eaglehawk and Mulga Bill, with the drill rig now operating at Side Well South for both exploration and resource definition purposes. The introduction of a second rig is expected to accelerate progress, ensuring the new targets can be tested without delaying ongoing programs.

At the Ironbark pit, geotechnical studies are planned, including diamond drilling to collect data for structural and metallurgical assessments. Recently completed waste rock characterisation drilling has provided samples for analysis, which will contribute to design and development planning.

Advancing the Side Well Project

The Side Well Gold Project, situated near Meekatharra, continues to be a key focus for the company as it works to expand its resource base. Alongside this, design work for the Ironbark pit is ongoing, aiming to optimise future development.

For investors following the broader market, keeping track of gold-focused explorers such as Great Boulder offers insight into sector trends, even when monitoring larger ASX 100 stocks for portfolio balance. While Great Boulder is not currently part of that index, its exploration results and expansion strategies contribute to the evolving Australian gold sector landscape.
