GBM Resources (ASX:GBM) started the first stage of the drilling program at the Yandan project in Queensland, according to a Tuesday filing with the Australian bourse.
The program includes 4,000 meters of reverse circulation and 4,000 meters of diamond drilling across four high-priority resource growth targets, the filing said.
Drill holes at the East Hill area will be prioritized to enable an updated mineral resource estimate to be delivered in the first half of 2027, per the filing.
