IMPERIAL REPORTS DRILLING AT MOUNT POLLEY EXTENDS MINERALIZATION 885 METRES BENEATH SPRINGER PIT

Imperial Metals Corp. has released diamond drill results from the final 18 diamond drill holes from the Mount Polley 2024 exploration program, including a notable interval of 895 metres grading 0.26 per cent copper and 0.32 gram per tonne gold starting from a depth of 27.5 metres, including 342.5 metres grading 0.42 per cent copper and 0.48 g/t gold starting from 27.5 metres, in diamond drill hole SD-24-196. The 2024 drilling at Mount Polley followed up on the significant results obtained in the 2023 drill program which focused on the Springer zone at Mount Polley.

Hole SD-24-196 was an angled hole oriented at 155 degrees/75 degrees (strike/dip), collared in the floor on the south side of the Springer pit. This hole, like the other holes in this drill program targeted gaps in drilling within the current pit designs (phase 5 and 6 pits) in the Springer zone and also to test for extended mineralization at depth. The results confirm that copper-gold mineralization extends vertically beneath the floor of the Springer pit for 885 metres. The results will be used to remodel the Springer zone mineralization, optimize the pit designs for the Springer pit, increase resolution in mine scheduling and potentially to consider pit expansions and further drilling.

A total of 7,377 metres of diamond drilling were completed at Mount Polley between March and May, 2024.

All the holes highlighted in the table were drilled from the Springer pit bottom.

Hole SD-24-183 was a vertical hole located in the centre of the Springer pit targeting an area with gaps in drilling. The drill hole intersected 160 metres grading 0.42 per cent copper and 0.43 g/t gold, starting from 7.5 metres depth, including 18.65 metres of 1.67 per cent copper and 1.57 g/t gold. This interval also intercepted 27.5 metres of 0.12 per cent molybdenum from 107.5 metres; this level of molybdenum mineralization is the highest ever intersected in the Springer zone.

Hole SD-24-190 was a vertical hole collared in the center of the Springer pit, about 35 metres northwest of hole SD-24-183. The drill hole intersected 249.0 metres grading 0.33 per cent copper and 0.39 g/t gold, starting from three metres depth, including 109.5 metres of rock grading 0.51 per cent copper and 0.54 g/t gold, starting from three metres.

Hole SD-24-191 was a vertical hole collared in the Springer pit, about 100 metres northwest of SD-24-183. The drill hole intersected 304.0 metres grading 0.24 per cent copper and 0.27 g/t gold, starting from six metres depth, including 34.0 metres grading 0.35 per cent copper and 0.47 g/t gold, starting from six metres depth.

Hole SD-24-192 was a vertical hole collared approximately 70 metres southeast of SD-24-183. The drill hole intersected 244.5 metres grading 0.26 per cent copper and 0.37 g/t gold, starting from 4.5 metres depth, including 96.80 metres of rock grading 0.39 per cent copper and 0.31 g/t gold, starting from 4.5 metres depth and 79.45 metres grading 0.26 per cent copper and 0.60 g/t gold, starting from 162.5 metres depth.

Hole SD-24-197 was an angled hole oriented at 040 degrees/65 degrees collared in the northern part of the Springer pit. This hole targeted an undrilled area along the northeastern boundary of the deposit in an area with high potential to hit higher-grade mineralization. The drill hole intersected 117.5 metres grading 0.32 per cent copper and 0.62 g/t gold, starting from 82.5 metres depth.

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 Mount Polley exploration program. Samples reported were analysed at Bureau Veritas Mineral Laboratories in Vancouver. 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.

About Imperial Metals Corp.

Imperial is a Vancouver-based exploration, mine development and operating company with holdings that include the Mount Polley mine (100 per cent), the Huckleberry mine (100 per cent) and the Red Chris mine (30 per cent).
