Stelar Metals (ASX:SLB) has completed an ultra-high-definition airborne survey at its Hill of Leaders Tungsten Project in the Northern Territory, which the company says has identified multiple structures for further drill targeting.
The magnetic and radiometric survey was flown along north-south traverses spaced 25m apart at a nominal height of 30m, with tie lines spaced 250m apart.
Preliminary imagery shows subtle structures and alteration patterns that were not visible in historical airborne data.
Known tungsten-rich vein sets at historical mines and workings occupy structures, faults, and alteration zones within the Hill of Leaders Granite.
Stelar says the new magnetic data has detected structures where the granite is obscured by shallow cover, including areas that have received little historical exploration.
The company is continuing to interpret the preliminary imagery, with final magnetic and radiometric datasets expected to help define specific drill targets within the identified structures.
Executive Chair Stephen Biggins says the survey will support the company’s upcoming drilling campaign.
“This new ultra-high-definition data has delivered exactly what we needed. By applying AI-powered processing to this exceptional imagery, we are identifying subtle, tungsten-bearing structures that previous explorers simply couldn’t see,” Biggins says.
“We now have a robust, data-backed pipeline of targets ready to test in our upcoming drill campaign.”
Stelar says the targets will be incorporated into a reverse circulation drilling program expected to commence in the coming weeks.
The survey follows a review of historical airborne data and modern satellite imagery to determine the preferred exploration method for vein-hosted tungsten mineralisation.
Stelar previously reported tungsten mineralisation associated with wolframite and scheelite across multiple quartz vein and greisen systems at Hill of Leaders.
The project covers 445km² and lies about 80km from Tennant Creek.
