Raiden Resources Unveils Encouraging Gold Signals from Arrow Aircore Drilling
Raiden Resources has completed an extensive aircore drilling program at its Arrow Gold Project, revealing promising gold and arsenic anomalies that hint at significant mineral potential. The joint venture partner Mallina Co Pty Ltd is set to advance follow-up studies to refine targets.
- 79 aircore holes drilled totaling 3,007 meters at Arrow Gold Project
- Highest gold assay of 26.5 ppb and arsenic of 196.7 ppm recorded in hole 24MALAC079
- Gold in soil trends correlate with elevated gold in bedrock from drilling
- Drilling targeted magnetic intrusives, shear zones, and hydrothermal alteration
- Mallina Co Pty Ltd finances exploration, with Raiden retaining lithium rights
Exploration Program Overview
Raiden Resources Limited (ASX: RDN) announced the completion of its aircore drilling campaign at the Arrow Gold Project in Western Australia's Pilbara region. The program, conducted in November 2024, comprised 79 holes totaling 3,007 meters, designed to test geochemical anomalies and define gold-bearing structures within the tenement E47/3476.
The drilling focused on six prospective zones identified through prior soil sampling and magnetic surveys, targeting geological features such as magnetic intrusive bodies, shear zones, and hydrothermal alteration, hallmarks of orogenic gold systems akin to the nearby Hemi deposit.
Key Findings and Geological Context
Assay results revealed elevated gold and arsenic values predominantly in the southern sector of the drilling area. Notably, hole 24MALAC079 returned the highest gold concentration at 26.5 parts per billion (ppb) alongside 196.7 parts per million (ppm) arsenic, associated with felsic intrusive and ultramafic lithologies. These findings align with soil geochemical trends, reinforcing the presence of gold mineralisation pathways.
The Arrow Project lies within the Mallina Basin, a geological setting characterized by folded Mesoarchean turbidites intruded by mafic-ultramafic sills and granitic bodies. The area is structurally influenced by the Wohler Shear, a significant regional fault system linked to gold emplacement in the region. The proximity, approximately 32 kilometers, to De Grey Mining's Hemi gold deposit adds strategic significance to the exploration results.
Joint Venture and Strategic Implications
Exploration activities at Arrow are fully funded by Mallina Co Pty Ltd, Raiden’s joint venture partner, allowing Raiden to maintain a free-carried interest while retaining 100% rights to lithium-caesium-tantalum (LCT) minerals. This arrangement exemplifies Raiden’s strategy to leverage partnerships for advancing its portfolio while focusing on value creation in key commodities.
Raiden’s Managing Director, Dusko Ljubojevic, highlighted the encouraging nature of the initial results, emphasizing that the wide drill spacing necessitates further work to refine targets. Mallina is currently undertaking detailed litho-geochemical and petrographic analyses to guide subsequent exploration phases.
Next Steps and Market Outlook
The follow-up program will focus on narrowing down drill targets based on the current dataset, potentially leading to more focused drilling campaigns. Given the geological similarities to the prolific Hemi deposit and the structural controls identified, the Arrow Project holds promise for significant orogenic gold mineralisation.
Investors and analysts will be watching closely as Mallina’s further studies and planned activities unfold, which could materially influence Raiden’s exploration trajectory and market positioning in the Pilbara gold sector.
Bottom Line?
Arrow’s initial aircore results lay a solid foundation, but the path to a meaningful discovery hinges on targeted follow-up work by Mallina.
Questions in the middle?
- Will follow-up drilling confirm higher-grade gold zones within the Arrow Project?
- How will Mallina’s litho-geochemical studies influence the next phase of exploration?
- What is the potential scale of gold mineralisation compared to nearby Hemi deposits?
