VANCOUVER, British Columbia, July 22, 2024 (GLOBE NEWSWIRE) -- Imperial Metals Corporation (“Imperial” or the “Company”) (TSX:III) reports 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% copper and 0.32 g/t gold starting from a depth of 27.5 metres, including 342.5 metres grading 0.42% copper and 0.48g/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°/75° (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 above were drilled from the Springer pit bottom.

Hole SD-24-183 was a vertical hole located in the center of the Springer Pit targeting an area with gaps in drilling. The drill hole intersected 160 metres grading 0.42% copper and 0.43 g/t gold, starting from 7.5 metres depth, including 18.65 metres of 1.67% copper and 1.57 g/t gold. This interval also intercepted 27.5 metres of 0.12% 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% copper and 0.39 g/t gold, starting from three metres depth, including 109.5 metres of rock grading 0.51% copper and 0.54 g/t gold, starting from three metres.
