  • 9m @ 114.7 g/t Ag Eq. from 263m inc. 2m @ 218.4 g/t Ag Eq. from 263m & 2m @ 196.0 g/t Ag Eq. from 270m downhole
• ORR075 was drilled 45m up-dip of ORR070 (which intersected 76m @ 118.5 g/t Ag Eq. from 24m downhole), and intersected 64m @ 123.6 g/t Ag Eq. from 4m downhole including:
  • 16m @ 240.5 g/t Ag Eq. from 8m inc. 6m @ 461.5 g/t Ag Eq. from 18m inc. 2m @ 913.1 g/t Ag Eq. from 21m downhole
  • 5m @ 207.7 g/t Ag Eq. from 59m inc. 3m @ 274.6 g/t Ag Eq. from 59m downhole
• ORR076 delivered multiple intercepts of high-grade mineralisation including:
  • 4m @ 164.2 g/t Ag Eq. from 12m downhole
  • 1m @ 527.7 g/t Ag Eq. from 89m downhole
  • 15m @ 116.6 g/t Ag Eq. from 141m inc. 2m @ 347.6 g/t Ag Eq. from 150m downhole
• ORR077 delivered multiple intercepts of high-grade mineralisation including:
  • 6m @ 251.7 g/t Ag Eq. from 95m inc. 2m @ 588.6 g/t Ag Eq. from 97m downhole
  • 5m @ 99.6 g/t Ag Eq. from 167m inc. 1m @ 226.9 g/t Ag Eq. from 170m downhole
  • 5m @ 97.8 g/t Ag Eq. from 242m inc. 2m @ 156.2 g/t Ag Eq. from 242m downhole
• Iltani has completed drillholes ORR078 to ORR089 (3,287m drilled) at Orient West with further assay results pending though May and June 2025
• Iltani is completing simultaneous RC and diamond infill drilling programs at Orient, with results used to model and estimate the initial JORC Resources for Orient West & East – expected Q3 CY2025

Iltani Managing Director Donald Garner commented:

“Holes ORR073 to ORR077 have continued to deliver excellent results from our Orient West JORC Infill drilling program and we continue to be excited by what we see, with results validating our belief that Orient is Australia’s largest and highest-grade known silver-indium deposit.

ORR075 intersected 64m @ 123.6 g/t Ag Eq. from 4m downhole and was drilled 45m up-dip of the intersection of 76m @ 118.5 g/t Ag Eq. from 24m in ORR070. This recent intersection contained multiple high-grade zones including:

• 16m @ 240.5 g/t Ag Eq. from 8m inc. 6m @ 461.5 g/t Ag Eq. from 18m inc. 2m @ 913.1 g/t Ag Eq. from 21m downhole; and
• 5m @ 207.7 g/t Ag Eq. from 59m inc. 3m @ 274.6 g/t Ag Eq. from 59m downhole

ORR073 was drilled 100m down-dip of ORR072 and intersected multiple high-grade zones, which remain open down-dip, including:

• 6m @ 101.2 g/t Ag Eq. from 29m downhole;
• 7m @ 116.1 g/t Ag Eq. from 50m inc. 2m @ 242.8 g/t Ag Eq. from 54m downhole;
• 7m @ 227.6 g/t Ag Eq. from 140m inc. 2m @ 651.8 g/t Ag Eq. from 143m downhole; and
• 9m @ 114.7 g/t Ag Eq. from 263m inc. 2m @ 218.4 g/t Ag Eq. from 263m & 2m @ 196.0 g/t Ag Eq. from 270m downhole

Drilling intersected high-grade mineralisation in ORR076 including 15m @ 116.6 g/t Ag Eq. from 141m inc. 2m @ 347.6 g/t Ag Eq. from 150m downhole and in ORR077 including 6m @ 251.7 g/t Ag Eq. from 95m inc. 2m @ 588.6 g/t Ag Eq. from 97m downhole.

Drilling continues at Orient, with both RC and diamond programs underway, and we will report further results through May and June as we work towards initial JORC resources for Orient West and East.”
