Iltani Resources (ASX:ILT) confirmed the presence of sulfide-rich mineralization at the Union Jack prospect within its Herberton project in Queensland, according to a Friday filing with the Australian bourse.

The drilling will be followed up with a downhole electromagnetic survey later this year to further understand the scale of the system, the filing said.

Meanwhile, preparation for the Isabel & Isabel Extended diamond drilling program is in progress, with drilling anticipated to start within a week, per the filing.
