King River Resources Uncovers New IOCG Targets in Tennant Creek Region
King River Resources advances exploration with new drill and soil sampling results at Tennant Creek, revealing promising IOCG-style mineralisation corridors and appointing a new Managing Director.
- Discovery of hydrothermal ironstones at Kuiper suggests regional IOCG target corridor
- Ionic soil sampling at Langrenus and BIF Hill East identifies subtle geochemical trends
- No significant assay results yet from Kuiper drilling but geological structures confirmed
- Appointment of Graham Gadsby as Managing Director to lead exploration growth
- Strong cash position of $2.56 million and $33.5 million investment in Tivan Limited
Exploration Progress at Kuiper and Tennant Creek
King River Resources Ltd (ASX, KRR) has reported its December 2025 quarterly activities, highlighting ongoing exploration efforts in the Northern Territory's Tennant Creek region. The company’s reverse circulation (RC) drilling at the Kuiper iron oxide copper gold (IOCG) targets, located approximately 35km east-northeast of Tennant Creek, has confirmed the presence of prospective Proterozoic geological units beneath shallow Cambrian cover. Although assay results from the six holes drilled did not return significant mineralisation, the discovery of hydrothermal ironstones within fault zones and iron alteration zones points to a broader regional IOCG-style mineralisation corridor within exploration licence EL31619.
This finding is significant as it suggests that the mineralising processes active in the well-known Tennant Creek mineral field may extend further east than previously understood. The Kuiper targets lie along a magnetic trend that may represent an eastern extension of the Warramunga corridor, a prolific IOCG province hosting deposits such as Emmersons Hermitage and Edna Beryl.
Soil Sampling Reveals Subtle Geochemical Anomalies
Complementing the drilling program, King River Resources completed ionic leach soil sampling at Langrenus, BIF Hill East, and EL31623. These geochemical surveys have identified subtle but coherent multi-element trends involving gold, copper, bismuth, silver, and molybdenum. At BIF Hill East, part of the Rover East project, the soil results align with strong gravity and magnetic anomalies, reinforcing the prospectivity of this IOCG target along strike from high-grade deposits such as Rover and Explorer.
Similarly, Langrenus, situated near historical mining operations and along the Mauretania-Hopeful Star trend, has shown encouraging geochemical signatures associated with quartz hematite breccia structures. These peripheral zones are known to be related to mineralised ironstones in the region, suggesting potential for further discoveries. However, the company notes that the ionic leach results are qualitative and require further validation due to the influence of varying regolith and cover sequences.
Strategic Leadership and Financial Position
In a move to strengthen its exploration leadership, King River Resources appointed Graham Gadsby as Managing Director in October 2025. Mr Gadsby brings extensive geological and executive experience to guide the company’s growth strategy. The board also issued 100 million unquoted performance rights to Mr Gadsby, aligning incentives with exploration success.
Financially, the company ended the quarter with a solid cash balance of $2.56 million and no debt. Additionally, King River holds a substantial investment in Tivan Limited, valued at $33.5 million as of January 2026, providing a strong asset base to support ongoing exploration activities. The company’s exploration expenditure for the quarter was $215,354, reflecting a disciplined approach to advancing its projects.
Outlook and Next Steps
King River Resources is continuing a comprehensive geological review and data consolidation of its Tennant Creek and Mt Remarkable tenements. This includes re-logging historical drill core and integrating datasets into advanced 3D models to refine targeting for future drilling campaigns. The company anticipates generating new drill targets in 2026 as it further interprets geophysical and geochemical data.
While the recent drilling at Kuiper has yet to yield significant assay results, the structural and geological insights gained, combined with encouraging soil geochemistry at multiple prospects, underscore the potential for meaningful discoveries in this underexplored region. Investors and analysts will be watching closely as King River advances its exploration programs and leverages its strengthened leadership team.
Bottom Line?
King River Resources’ methodical exploration and strategic leadership appointments set the stage for potential breakthroughs in the Tennant Creek IOCG corridor.
Questions in the middle?
- Will upcoming drilling at Kuiper and other targets confirm economically viable mineralisation?
- How will King River Resources prioritise and fund its expanding exploration pipeline in 2026?
- What impact will the new Managing Director have on accelerating project development and market confidence?
