IMPERIAL PROVIDES HUCKLEBERRY EXPLORATION UPDATE

All nine drill holes of Imperial Metals Corp.'s 2025 Huckleberry mine diamond drilling program, totalling 1,743 metres, have intersected copper, molybdenum, silver and gold mineralization. Drill hole MZ-25-1 intersected an elevated gold interval of 22.6 metres of 0.23 gram per tonne (g/t) gold from 73.7 to 96.3 metres.

The Huckleberry mine (100 per cent 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. The 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 are detailed in the attached table.

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.

Additional drilling is being considered for 2026.

The Whiting Creek prospect is part of Huckleberry and is a significant copper-molybdenum exploration target located in west-central B.C.

At Whiting Creek, located 8.5 kilometres north of the Huckleberry mill, three stepout 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 centred on the biotite-rich Whiting Creek stock.

Drill holes WC-25-1 and WC-25-2 were stepout holes and targeted a historical copper soil anomaly to the east of the Creek zone. Both holes intersected broad zones of low-grade copper and molybdenum mineralization.

Drill hole 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 dikes and dikes 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 and south, and to depth, with locally elevated molybdenum grades such as the 12.5-metre interval of 0.16 per cent molybdenum from 352.5 metres in hole WC-25-002.

Jim Miller-Tait, PGeo, Imperial's vice-president of 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 (quality assurance/quality control) 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.
