Iltani Resources Limited announces its first JORC Resource for the Orient West Silver-Indium deposit, highlighting 21.6 Mt @ 100.5 g/t Ag Eq. With strong silver yields and solid resource numbers, the company’s Australia-based project shows promising growth and reinforces its position in the dynamic minerals sector.
Iltani Resources Limited has announced its maiden JORC Mineral Resource Estimate for the Orient West Silver-Indium deposit, part of its larger Orient Silver-Indium Project near Herberton in Northern Queensland. The independent estimate, prepared by Mining One, reports a resource of 21.6 million tonnes grading 100.5 g/t silver equivalent (using a 60 g/t Ag Eq cut-off), which contains approximately 18.7 million ounces of silver. The higher‐grade resources are embedded within a broader mineralisation envelope estimated at 42.7 million tonnes grading 73.8 g/t silver equivalent (at a 30 g/t Ag Eq cut-off), equating to roughly 27.0 million ounces of contained silver. In this estimate, 56% of the tonnage falls in the Indicated category, with the remainder classified as Inferred.
The announcement details robust drilling programs, including 116 reverse circulation holes and several diamond holes that have mapped significant vein continuity along a strike length of over 1,000 meters and to depths averaging 200 meters. The process involved systematic sampling, rigorous assay methods, and advanced 3D block modelling using techniques such as ordinary kriging and inverse distance squared estimation. The technical report explains that the resource is defined within a pit shell optimised for eventual open pit mining, with metallurgical test work already indicating the potential to produce saleable lead-silver and zinc-indium-silver concentrates.
Iltani has also outlined progress at its Orient East project, where initial infill drilling results have been completed. The company plans to release a maiden JORC resource estimate for Orient East by September 2025. Further drilling programs at both locations aim to test extensions in strike and depth, with the goal of advancing a global resource model for Australia’s largest known silver-indium project.
Beyond the resource figures, the detailed technical information covers drilling techniques, sampling protocols, geological interpretations, and detailed density and metallurgical studies. These comprehensive measures underpin the company’s strategy to validate and eventually economically extract the mineralisation by utilising standard open pit mining methods.
Bullish sentiment arises from the strong technical milestones achieved within a relatively short exploration timeframe – just two years since listing. The clear continuity of high-grade mineralisation, robust independent resource estimates, and promising metallurgical test results pave the way for future resource expansions and potential economic feasibility studies, bolstering confidence among investors and beginner traders.
Bearish sentiment may stem from the inherent uncertainties that accompany early-stage resource estimates, such as the reliance on further infill drilling to convert additional Exploration Targets into Mineral Resources. Additionally, the technical complexities, including robust sampling and modelling processes, underscore the risks involved in progressing from exploration to an economic mining operation. Any delay in proving economic viability or changes in commodity prices could impact the overall project outlook.
Investors keeping a close watch on Iltani Resources Limited’s progress will find these developments key steps in establishing a solid portfolio position within Australia’s critical minerals sector.
