Imperial drills 1,743 m in nine holes at Huckleberry

Executive Summary

• Imperial Metals Corp. completed its 2025 Huckleberry mine diamond drilling program, intersecting copper, molybdenum, silver, and gold mineralization in all nine drill holes (1,743 metres total).
• The program successfully infilled the main zone mineral resource to the southwest and identified higher-grade mineralization at relatively shallow depths, including a significant elevated gold interval.
• Exploration at the Whiting Creek prospect also yielded results, with stepout holes intersecting broad zones of low-grade copper and molybdenum mineralization, confirming the system remains open to the east, west, south, and depth.

Key Details

• Huckleberry Main Zone Drilling:
  • Total of nine drill holes completed, totalling 1,743 metres.
  • All holes intersected copper, molybdenum, silver, and gold mineralization.
  • Significant Gold Interval: Drill hole MZ-25-1 intersected 22.6 metres of 0.23 g/t gold from 73.7 to 96.3 metres.
  • Mineralization is primarily hosted in volcanic rock surrounding the main zone stock, with some molybdenum mineralization continuing into the stock itself.
  • The drilling targets the southern contact between the main zone intrusive stock and surrounding host volcanic rock, expanding upon and infilling the main zone mineral resource to the southwest.
  • Historic drilling (pre-2020) was not assayed for gold or silver; 2025 results and resampling of 18 historic holes will be integrated into the block model for mine planning.
• Whiting Creek Prospect Drilling:
  • Located 8.5 km north of the Huckleberry mill; three stepout drill holes completed totalling 1,870 metres.
  • Holes WC-25-1 and WC-25-2: Targeted a historical copper soil anomaly to the east of the Creek zone; intersected broad zones of low-grade copper and molybdenum mineralization.
  • Hole CW-25-006: Follow-up to 2023 drilling west of the Creek zone; intersected andesitic volcanic rocks cut by plagioclase porphyry diorite and granodioritic dikes.
  • Significant Molybdenum Interval: Hole WC-25-002 intersected 12.5 metres of 0.16% molybdenum from 352.5 metres.
  • Copper and molybdenum mineralization is widespread within the Whiting Creek stock and surrounding volcanics; the system remains open to the east, west, south, and to depth.
• Operational Updates:
  • Additional drilling is being considered for 2026.
  • Samples analyzed at Activation Laboratories Ltd. with a full QA/QC program completed.
  • Jim Miller-Tait, PGeo, Imperial's vice-president of exploration, is the designated Qualified Person.
