Imperial Provides Huckleberry Exploration Update
Vancouver | November 27, 2025 | Imperial Metals Corporation (“Imperial” or the “Company”) (TSX:III) is
pleased to report that all nine drillholes of the 2025 Huckleberry mine diamond drilling program, totalling
1,743 metres, intersected copper, molybdenum, silver , and gold mineralization. Drillhole MZ-25-1
intersected an elevated gold interval of 22.6 metres of 0.23 g/t gold from 73.7 to 96.3 metres.
The Huckleberry mine (100% owned by Imperial) located in west-central British Columbia operated from
1997 to 2016, when it was placed on care and maintenance due to low copper prices. While the mine is
currently inactive, the property remains an exploration target for the Company.
The 2025 diamond drilling program at the Huckleberry mine tested an underexplored area southwest of
the Main Zone pit. Angled diamond drill holes were designed to intersect the southern contact between
the Main Zone intrusive stock and the surrounding host volcanic rock. Historically, the bulk of ore mined
from the Main Zone occurred near this contact in the volcanic rock east and northeast of the Main Zone
stock. The 2025 drilling expands upon and infills the Main Zone mineral resource to the southwest. Th e
program was successful in intersecting some higher-grade mineralization at relatively shallow depths.
The historic drilling (pre-2020) at Huckleberry was not assayed for gold or silver. However, gold and silver
were recovered and were present at payable levels in all the copper concentrate produced at Huckleberry.
Gold and silver assay results from the 2025 drilling and the resampling of 18 historic holes from the Main
Zone will be included in the block model for the Main Zone deposit and will enable gold and silver values
to be integrated into mine planning.
Significant intervals include:

Most of the mineralization from 2025 drilling is hosted in the volcanic rock surrounding the Main Zone
stock, but some mineralization, especially molybdenum, continued into the stock itself.

MZ-25-7a). Looking West.
The Whiting Creek prospect is part of Huckleberry and is a significant copper -molybdenum exploration
target located in west-central British Columbia.
At Whiting Creek, located 8.5 kilometres north of the Huckleberry mill, three step-out drill holes totalling
1,870 metres were completed during the 2025 exploration program. The prospect is a classic calc-alkalic
porphyry system related to the Bulkley plutonic suite, similar in style to Huckleberry and is centered on
the biotite-rich Whiting Creek stock.
Drillholes WC-25-1 and WC-25-2 were step out holes and targeted a historic copper soil anomaly to the
east of the Creek Zone . B oth holes intersected broad zones of low -grade copper and molybdenum
mineralization.
Drillhole CW-25-006, drilled west of the Creek Zone, was a follow up to 2023 drilling. This hole intersected
primarily andesitic volcanic rocks cut by plagioclase porphyry diorite dykes and dykes of granodioritic
composition.
Copper and molybdenum mineralization is widespread both within the Whiting Creek stock and in the
surrounding volcanics. The system remains open to the east, west, south and to depth with locally elevated
molybdenum grades such as the 12.5 metre interval of 0.16% molybdenum from 352.5 metres in hole WC-
25-002.

Jim Miller -Tait, P .Geo., Imperial’s VP Exploration, has reviewed this news release as the designated
Qualified Person as defined by National Instrument 43 -101 for the Huckleberry and Whiting Creek
exploration programs.
Samples reported were analyzed at Activation Laboratories Ltd. located in Kamloops. A full QA/QC
program using blanks, standards and duplicates was completed for all diamond drilling samples submitted
to the labs. Significant assay intervals reported represent apparent widths. Insufficient geological
information is available to confirm the geological model and true width of significant assay intervals.
