King River Resources (ASX:KRR) Advances Gold-Copper Exploration with Promising Results

Highlights

• The company completed 942m of reverse circulation drilling at the Kurundi Project.
• The program identified new gold mineralisation with a best intersection of 4m at 1.43 g/t gold, including 2m at 2.79 g/t gold.
• Ionic leach soil sampling at the Kuiper IOCG targets outlined geochemical anomalies associated with magnetic and gravity trends identified in earlier surveys.
• The bismuth anomaly at Kuiper West aligns with a main gravity target.
• RC drilling at Kuiper East and West was completed in September 2025, with assay results pending.
• The company holds AUD 3.27 million in cash, carries no debt, as of end of the quarter.

King River Resources Ltd (ASX:KRR) has provided its quarterly update for the period ended 30 September 2025, reporting steady progress across its gold-copper projects in the Tennant Creek region of the Northern Territory. The company received reverse circulation (RC) drill assays from the Kurundi Project and soil sampling results from the Kuiper iron oxide copper gold (IOCG) targets within the Tennant East Project area.

These activities form part of KRR’s AUD 2 million drilling budget, aimed at testing high-priority gold and IOCG targets generated from its 2023 geophysics program. Exploration efforts continue to focus on key areas within Rover East, Barkly, Tennant East, and Kurundi.

Encouraging RC Drill Results at Kurundi Project

The company completed 942m of RC drilling across 13 holes at the Kurundi Project in April 2025. The program targeted extensions to two high-grade gold zones at Kurundi Main and a newly discovered mineralised structure.

Gold assay results were returned from this new structure, with a best intersection of 4m at 1.43 g/t gold, including 2m at 2.79 g/t gold from 9m in hole TTRC188. The discovery is considered promising, with mineralisation remaining untested along strike and at depth.

A large zone of historical alluvial gold workings surrounds the target area, suggesting potential for additional undiscovered mineralisation. Further drilling will be required to determine the orientation of this mineralisation, as the dip, surface expression, and width of the structure remain unknown.

Promising Geochemical Anomalies from Kuiper Soil Sampling

At the Kuiper IOCG target area, ionic leach soil sampling identified encouraging geochemical anomalies coinciding with magnetic and gravity targets mapped during the 2023 surveys. Trace element anomalies including Au, As, Ag, Cu, and Bi were detected across Kuiper East and West zones.

Geochemical mapping of elements commonly associated with ironstones and magnetite reveals distinct trends that align with the geophysically interpreted ironstone target zones at Kuiper East and Kuiper West.

Notably, the bismuth anomaly at Kuiper West aligns with the main gravity target. These findings support the interpretation of potential ironstone-associated mineralisation. RC drilling at both Kuiper West and Kuiper East commenced in July 2025 and was completed in September, with assay results pending.

Ongoing and Future Exploration Programs

Data source: Company update

The company expects to generate additional targets as it continues interpreting geophysical data and drill assays. Further ionic leach soil sampling will be conducted to prioritise targets for upcoming drill programs. Ionic leach soil sampling has been concluded at Kuiper 1 and 2.

Corporate Update

As of 30 September 2025, the company held AUD 3.27 million in cash and carried no debt. The company also maintains investments in ASX-listed Tivan Limited, holding 100 million shares valued at approximately AUD 17.5 million and four million options.

In September, KRR announced the appointment of Graham Gadsby as Managing Director, effective 14 October 2025. The company’s annual general meeting is scheduled for 21 November 2025.

KRR shares were trading at AUD 0.017 per share at the time of writing on 23 October 2025.
