Iltani Resources has uncovered 16 high-priority anomalies in a helicopter-borne VTEM survey at its Herberton project in northern Queensland, host of Australia’s largest known silver-indium deposit.
The survey, conducted by UTS Geophysics and modelled by Mitre Geophysics, revealed strong electromagnetic responses across known mineralisation and previously untested ground.
Thirteen anomalies were identified in the Orient and Deadman Creek area, with more than 50 modelled plates pointing to significant potential to expand mineralisation.
“With Mitre having completed the modelling of the Herberton project VTEM survey data, we can now plan how we will work through the targets,” Iltani Resources managing director Donald Garner said.
“The modelling has defined 16 high-priority anomalies, likely to be sulphide mineralisation, and of these, 13 anomalies consisting of at least 50 plates were modelled at Orient and Deadman Creek.
“We are very pleased with this outcome, as it confirms the size and scale of the overall Orient system, and the potential for Iltani to discover materially more mineralisation at Orient.”
Iltani and Mitre have mapped out a two-phase program to advance exploration. Phase one involves a nine-hole RC drilling program to test shallow plates, while phase two will use surface electromagnetic (EM) surveys to refine deeper targets before drilling.
“Our priority is testing the targets at Orient and Deadman Creek, and to do this, we have split the targets into shallow targets for reverse circulation drilling, and deeper targets, where we need to better define the targets prior to drilling, likely by using surface EM surveys,” Garner said.
“Whilst we are drill-testing the Orient anomalies, we are systematically working our way through the remaining anomalies within the central area of the Boonmoo Sag Caldera, visiting their locations to conduct mapping and sampling to see if there is anything visible at surface causing the anomaly, and then rank the targets based on the field visit plus modelling and then proceed to drill-test.”
Iltani’s work has been backed by $230,375 in funding from the Queensland Government’s Collaborative Exploration Initiative, part of its Resources Industry Development Plan.
