Highlights
- King River Resources has completed the acquisition of the Mindoolah Gold Project, adding a historically productive asset in Western Australia’s Murchison Province.
- Historical drilling at Mindoolah has identified multiple unmined high-grade intercepts across the Excelsior, Le Soleil and Bertram’s prospects.
- Rock chip, underground and stockpile sampling have confirmed widespread gold mineralisation, with some surface results exceeding 40 g/t Au.
- Advanced LiDAR and photogrammetry surveys, along a planned airborne magnetic survey, are being deployed to refine structural interpretation and drill targeting at Mindoolah.
- Ionic leach soil sampling at Tennant Creek outlined multi-element anomalies.
King River Resources Ltd (ASX:KRR) reported a dynamic quarter ended 31 March 2026, marked by a strategic expansion of its exploration portfolio and continued progress across its Northern Territory assets. The period was highlighted by the acquisition of the Mindoolah Gold Project in Western Australia, alongside advancing geochemical programs, detailed geological assessments, and preparation for advanced geophysical surveys aimed at refining drill targets.
Mindoolah Acquisition Expands Exploration Footprint
During the quarter, the company completed the acquisition of the Mindoolah Gold Project, located north-west of Cue in Western Australia’s Murchison Province. The project sits within the Youanmi Terrane of the Archaean Yilgarn Craton, a region known for significant gold endowment. Details of the transaction, here.
Historical production at Mindoolah Mining Centre, dating back to around 1901, averaged 19.02 grams per tonne gold for approximately 5,762 ounces. Mining activity was historically limited by shallow water table conditions (at depth of approximately 21m) and later economic factors (low gold prices), leaving areas of mineralisation unmined.
The project area covers roughly 100 square kilometres of prospective greenstone lithologies, including banded iron formations, mafic volcaniclastics and amphibolite.
Drill Results Highlight Near-Surface Potential
Historical drilling across Mindoolah has identified multiple unmined high-grade drill intercepts across key prospects. At the Excelsior Prospect, results include intersections such as
- 4m @ 9.30 g/t Au from 33m (RCH004)
- 4m @ 8.85 g/t Au from 32m (RCH009)
- 2m @ 9.38 g/t Au from 33m (RCH010)
- 1m @ 7.81 g/t Au from 39m (RCH012)
- 2m @ 6.24 g/t Au from 30m (RCH011)
Additional intercepts were recorded at th Le Soleil and Bertram’s prospects, confirming mineralisation across several zones.
At th Le Soleil Prospect, significant intercepts include 2m @ 2.38 g/t Au from 23m (RCH018) and 3m @ 1.83 g/t Au from 29.6m (RCH017). While at the Bertram’s prospect, significant intercept included 6m @ 0.92 g/t Au from 41m (25MDRC002).
Rock chip sampling has further demonstrated widespread gold distribution. Underground sampling across multiple levels returned average grades of 6.59 g/t gold, while surface and stockpile sampling produced results exceeding 40 g/t gold in some locations.
Advanced Mapping and Geophysics Underway
KRR will undertake a comprehensive airborne magnetic survey across the Mindoolah Gold Project, with Pegasus Airborne Systems engaged to acquire high-resolution data on 50m line spacing using a helicopter platform.
Additionally, the company has engaged Jurovich Surveying for high-resolution LiDAR and photogrammetry surveys to generate structural interpretations and for stockpile evaluation. A magnetic survey is scheduled across the project to define new structural & lithological controls and identify extensions to known mineralisation.
Additional work programs include bulk sampling program, structural mapping and preparation for maiden air-core drilling targeting the margins of the Mindoolah Monzogranite.
Tennant Creek Sampling Supports Target Generation
In the Northern Territory, ionic leach soil sampling results were received from the Langrenus, BIF Hill East and EL31623 prospects. The results identified coherent multi-element geochemical trends. Following the integration with structural and geophysical interpretations, the results provide supporting data to refine drill-ready targets. Additional work is required to enhance and validate the significance of these geochemical responses.
Corporate Position and Investment Activity
As at 31 March 2026, the company reported total cash and listed investments of AUD 32.1 million. During the quarter, partial divestment of listed securities contributed funding toward the Mindoolah acquisition.
The March 2026 quarter was defined by the addition of the Mindoolah Gold Project and continued evaluation of Tennant Creek assets. Exploration activities focused on integrating geological, geochemical and geophysical data to refine drill targets. With mapping, sampling and geophysical surveys progressing, the company is advancing toward the next phase of exploration across its key projects.
KRR shares traded 7.41% higher at AUD 0.029 per share on 28 April 2026.
