Silver and base metals explorer Iltani Resources (ASX:ILT) has received final assay results from its recent diamond drilling program at the Orient Silver-Indium Project in Herberton, North Queensland.
The program, conducted as part of the Orient Mining option study, comprised two drillholes—ORD006 at Orient West and ORD007 at Orient East—designed to generate representative samples for initial metallurgical test work.
ORD006 intersected 35m at 98.1 g/t silver equivalent from 80m, including high-grade zones such as 4.2m at 278.5 g/t Ag Eq. and 0.4m at 1,126.2 g/t Ag Eq.
ORD007 returned 27m at 225.2 g/t Ag Eq. from 77m, including 1.5m at 2,414.5 g/t Ag Eq.
Iltani has dispatched a 240 kg bulk sample—120 kg from each drill site—to Core Resources in Brisbane for metallurgical testing, expected to be completed by mid-2026.
The results closely align with previous reverse circulation drilling, reinforcing confidence in the resource definition and supporting planned RC drilling in 2026.
Managing Director Donald Garner stated, "The diamond drilling has confirmed wide zones of high-grade mineralisation at Orient West and East, providing a robust basis for our upcoming metallurgical test work and future drilling programs."
The Orient Project, part of Iltani's Herberton portfolio, remains Australia’s largest known silver-indium deposit, with a current mineral resource estimate of 34.2 million tonnes at 110.4 g/t Ag Eq.
