Orient West Drilling Confirms Open-Ended High-Grade Silver-Indium Potential
Iltani Resources reports continued broad high-grade silver and base metals assay results from recent drilling at its Orient West project in Queensland, reinforcing its status as Australia's premier silver-indium discovery.
- Broad high-grade silver-equivalent intercepts from drillholes ORR073 to ORR077
- Mineralisation remains open at depth and along strike
- 64m at 123.6 g/t Ag Eq. intersected in ORR075 including zones exceeding 900 g/t Ag Eq.
- Additional drilling completed with assays pending for holes ORR078 to ORR089
- Initial JORC resource estimates for Orient West and East expected by Q3 2025
Strong Continuity in High-Grade Mineralisation
Iltani Resources Limited (ASX: ILT) has delivered another tranche of encouraging assay results from its ongoing JORC infill drilling program at the Orient West Silver-Indium Project in North Queensland. The recent reverse circulation drillholes ORR073 to ORR077 have returned broad zones of high-grade silver-equivalent mineralisation, confirming the continuity of the deposit both down dip and along strike.
Notably, drillhole ORR075 intersected 64 metres at 123.6 grams per tonne silver equivalent starting just 4 metres below surface. Within this interval, multiple higher-grade zones were recorded, including an exceptional 2 metres at 913.1 g/t Ag Eq. These results closely follow earlier intersections such as 76 metres at 118.5 g/t Ag Eq. in ORR070, underscoring the robustness of the mineralised system.
Depth and Strike Potential Remain Open
Drillhole ORR073, positioned 100 metres down-dip from previous drilling, intersected multiple high-grade veins with grades up to 651.8 g/t Ag Eq. over 2 metres. Similarly, ORR076 and ORR077 delivered significant intercepts, including 15 metres at 116.6 g/t Ag Eq. and 6 metres at 251.7 g/t Ag Eq., respectively. The mineralisation remains open at depth, suggesting potential for both open pit and underground mining operations.
These results validate Iltani’s belief that the Orient project hosts Australia's largest and highest-grade known silver-indium deposit. The company is advancing towards defining an initial JORC-compliant Mineral Resource Estimate, targeting the high-grade core area measuring approximately 900 by 350 metres.
Ongoing Drilling and Resource Estimation
Iltani has completed additional drilling from ORR078 to ORR089, totaling over 3,200 metres, with assay results expected through May and June 2025. The company is conducting simultaneous reverse circulation and diamond drilling to refine the geological model and support resource estimation.
Managing Director Donald Garner emphasized the significance of the recent results, highlighting the continuity and grade consistency that underpin the upcoming resource estimate. The initial JORC resources for Orient West and East are anticipated in the third quarter of calendar year 2025, a key milestone for the project’s development trajectory.
Strategic Positioning in Critical Minerals
Beyond silver and indium, the Orient project also contains base metals such as lead and zinc, which contribute to the overall metal equivalent grades. Iltani’s metallurgical test work supports the recoverability of these metals into concentrates, enhancing the project's economic potential.
With a portfolio that includes other advanced exploration projects in Queensland and Tasmania, Iltani Resources is positioning itself as a significant player in the supply of critical minerals essential for a low-emission future.
Bottom Line?
As Iltani advances towards its inaugural JORC resource estimate, the market will be watching closely to see if these high-grade intercepts translate into a commercially viable deposit.
Questions in the middle?
- How will the pending assay results from drillholes ORR078 to ORR089 impact the resource model?
- What is the expected timeline and confidence level for upgrading the Exploration Target to a JORC Mineral Resource?
- Could the presence of additional metals like antimony and tin materially affect the project's economics if included in future metallurgical recoveries?
