King River Resources (ASX:KRR) said a reverse circulation drill rig is scheduled to mobilize to its Mindoolah gold project in Western Australia this week, according to a Monday Australian bourse filing.

The drilling program is designed to test selected waste dumps and stockpiles across the Mindoolah Mining Centre to assess gold distribution, material variability, and the potential for a near-surface mineralized stockpile inventory.

The company also started a bulk density characterization program across the primary target areas, including the Cundy, Excelsior, and Mindoolah Main Reef waste dumps, per the filing.
