A recent mapping and sampling program at the Antimony Reward project in Queensland has confirmed the presence of significant antimony mineralisation across two key vein systems.
A total of 19 samples were taken from two mapped vein systems, with vein system 1 producing an assay result of 16.2 per cent antimony, with a maximum result of 46.5 per cent and vein system 2 returned an average of 10.9 per cent antimony, peaking at 17.7 per cent.
The high-grade mineralisation extends beyond the previously drilled zone in vein system 1, which has a strike extent of over 500m. Vein system 2, which has not been drilled before, has a strike extent of 300m.
Iltani is now preparing to commence drilling at the Antimony Reward project, with operations expected to start in late September or early October following consultation with the landowner and First Nations group.
“It will be great to see the drill rig in action as we are extremely excited about the potential of the Antimony Reward system to deliver a high-grade antimony resource and with antimony currently trading at $US25,100 per tonne, there is not a better time to be doing this work,” Iltani managing director Donald Garner said.
“The antimony mineralisation sampled at Antimony Reward to date contains exceptionally low arsenic. Arsenic is a key penalty element with regards to antimony concentrates, so this is another good sign.”
The timing is significant, as China, the world’s largest producer of antimony, recently imposed export controls on some antimony products, causing prices to jump.
The Antimony Reward project is part of Iltani’s Herberton project, located within the Featherbed volcanic complex, known for structurally controlled stibnite mineralisation in epithermal quartz veins.
Itani has designed a preliminary 15-to-20 hole (1500m) reverse circulation drilling program to test the mineralisation.
