Iltani Resources advances toward a JORC-compliant resource estimate for Orient West
Infill drilling confirms continuity of mineralised systems at Herberton Project
Modelling initiated for Orient East with drilling expected to resume by month-end
Exploration and development activity continues within the base and precious metals sector, with Iltani Resources Ltd (ASX:ILT), listed on the All Ordinaries, advancing plans for a maiden resource estimate at its Orient West deposit in North Queensland. The company recently completed an infill drilling program across the Herberton Project, specifically targeting the high-grade vein systems at Orient West.
The company confirmed that independent modelling is now underway, with a formal resource estimate scheduled for release in the coming quarter. The Herberton Project covers a large portion of the Herberton Mineral Field, a region historically known for tin mining but which also contains documented mineralisation across silver, zinc, copper, and associated metals.
Orient West Drilling Supports Open Pittable Resource Concept
Drilling at Orient West was executed as part of a broader program designed to improve geological confidence and provide support for future resource classification. The program targeted areas containing multiple intersecting high-grade veins surrounded by mineralised stockwork zones.
The company highlighted that continuity along both dip and strike was demonstrated within the tested zones. Iltani stated that several zones with moderate-grade mineralisation form envelopes around higher-grade intersections, providing geological context supportive of a potential open-pit resource scenario.
Modelling Underway at Orient East as Assays Awaited
Parallel efforts are progressing at Orient East, another key prospect within the Herberton Project. Drillholes have been completed at this site, with laboratory results pending for several recent holes. The company anticipates publishing a separate mineral resource estimate for Orient East later in the September quarter.
In the meantime, geophysical modelling has begun on the finalised versatile time-domain electromagnetic (VTEM) data. This effort is being led by specialist contractor Mitre Geophysics, with the goal of defining additional high-priority drill targets.
Drilling to Resume Following Geophysical Interpretation
Once modelling is finalised, Iltani intends to recommence drilling activities at the Orient targets. The focus will be on geophysical anomalies interpreted as possible extensions of existing mineralised systems. The company has indicated that this drilling may aim to increase resource tonnage and support additional grade continuity across broader areas of the Herberton tenement.
The Herberton Mineral Field itself has a deep mining legacy with over two thousand known occurrences, historically mined for a diverse suite of commodities including tin, tungsten, copper, bismuth, and silver-lead-zinc mineralisation. Iltani’s project area covers extensive ground in this prolific and underexplored Queensland region.
