King River Resources (ASX:KRR) to Begin Major Survey Campaign at Mindoolah Gold Project

Highlights

• KRR has announced a comprehensive exploration program for its Mindoolah Gold Project, featuring airborne magnetic, LiDAR, photogrammetry, and bathymetric surveys.
• The program aims to generate detailed structural insights and evaluate historic stockpiles to support future exploration and drilling phases.  
• The 50m-spaced airborne magnetic survey is designed to map subsurface structures and identify new drilling targets.
• High-resolution photogrammetry and LiDAR will create a detailed “Digital Twin” of the project area, allowing geologists for centimetre-scale structural analysis.
• Surveys will assess historic surface stockpiles and measure water volumes in the Excelsior Pit.

King River Resources Ltd (ASX:KRR) has announced an exploration update for its Mindoolah Gold Project in Western Australia. The update details a comprehensive exploration program that includes airborne magnetic survey, LiDAR, photogrammetry and bathymetric survey, all aimed at advancing the next phase of exploration and drilling at the project.

The program is designed to generate detailed structural insights across the project area, while also evaluating existing stockpiles and operational readiness. Contractors have been engaged to conduct specialised surveys, and they are expected to be commissioned in mid to late April 2026.

Airborne Magnetic Survey to Improve Target Identification

As part of the exploration program, Pegasus Airborne Systems will conduct a helicopter-supported 50m-spaced airborne magnetic survey across the project area. The resulting dataset is expected to assist in mapping subsurface structures and identifying potential drilling targets for upcoming exploration programs.

LiDAR and Photogrammetry to Build Detailed Geological Model

Jurovich Surveying has been engaged to complete high-resolution LiDAR and photogrammetry surveys. LiDAR will generate a detailed Digital Terrain Model by penetrating vegetation and reveal the ‘bare earth’ surface.

The LiDAR mapping will help identify structural lineaments, faults and historical surface workings that may not be visible in conventional mapping methods. When combined with high-resolution photogrammetry, the data will form a “Digital Twin” — that allows centimetre-scale structural analysis.

Operational Planning and Stockpile Assessment

In addition to geological mapping, the exploration program includes surveys focused on operational planning. A bathymetric sonar survey will be conducted within the Excelsior Pit to calculate water volumes and map the submerged pit structure. This information will assist with drilling logistics and future planning related to dewatering activities.

LiDAR surveys will assist in estimating the volumes of historic surface stockpiles. By combining these volumetric measurements with sampling data, the company intends to evaluate whether the material may present opportunities for processing or off-take in the future.

Digitising Historical Gold Records

The company’s technical team has completed a spatial reconciliation of the Mindoolah Project. Archival government documents and historic Gold Mining Lease records were compared with satellite imagery to build a precision-mapped geological database.

This process has enabled the precise mapping of historical production locations, including the Cundy Reef where grades of up to 988 grams per tonne gold were previously recorded. By assigning GPS coordinates to historic shafts, pits and production records, the company has been able to identify where past mining activities ended.

King River Resources’ latest exploration activities at the Mindoolah Gold Project combine modern surveying technologies with historical mining data to support the next stage of exploration. With airborne geophysics, LiDAR mapping and operational assessments scheduled to begin in April 2026, the program aims to generate detailed geological insights while also evaluating historic stockpiles and drilling logistics. The integration of these datasets is expected to guide future drill program design and provide a more comprehensive understanding of the project’s mineralised systems.
