Mount Polley Mine – Exploration
The Mount Polley Phase 2 exploration program in 2024, consisting of 6,758 metres in 27 diamond drill
holes, had two objectives. First, complete near-pit drilling targeting the Springer Pit rim and the C2 Zone
located just south of the now combined Springer -Cariboo pit and close to the concentrator . The second
was to test high priority geophysical, structural, geochemical and geological targets outside of the active
pit area.
The highlight of this drilling campaign is h ole C2-24-115 which intersected 127.5 metres grading 0.72%
copper and 1.43 g/t gold, starting from 302.5 metres. The hole targeted a deeper, higher grade C2
mineralization that had been intersected by three historic drill holes. Mineralized intervals in these three
holes included hole C2-11-101 with 34.5 metres of 0.54% copper and 0.95 g/t gold from 297.5 metres,
hole C2-11-97 with 57.5 metres of 1.16% copper and 2.07 g/t gold from 340.0 metres, and hole C2 -11-
100 with 64.3 metres of 0.72% copper and 0.99 g/t gold from 382.5 metres. This mineralization is deep,
but grades may be sufficient to consider underground mining. This zone is open to depth.

The other Phase 2 holes in the C2 Zone targeted near to surface mineralization and include a notable
interval of 222 metres grading 0.45% copper and 0.62 g/t gold starting from a depth of 18 metres (sub -
crop) in diamond drill hole C2-24-110.
The table below includes significant intervals in the 2024 C2 Zone drilling.

Historically, a small pit was excavated in the C 2 Zone adjacent to the ramp into the Cariboo pit, and
mineralization in this zone has a high gold to copper ratio. The 2024 near surface drilling was conducted
to see if the small C2 pit design could be expanded to take advantage of the current high gold price. The
mineralization in this zone is centered approximately 900 metres southeast from the cent re of the now
combined Springer-Cariboo pit and close to the concentrator.
Two holes were drilled from the rim of the north end of the Springer Pit to test an undrilled part of the
Phase 5 pushback in the Springer Pit. Hole SD-24-201 intersected 93.7 metres grading 0.28% copper and
0.37 g/t gold from 188.8 metres and hole SD -24-202 intersected 82.5 metres grading 0.23% copper and

0.26 g/t gold from a depth of 100 metres. The results from these holes will be used to update the block
model in this relatively undrilled part of the Springer deposit.
The Gatehouse Zone was a blind target located 600 metres east of the mill and was targeted based on
known structural trends, geology and geophysics. Hole GH -24-01 intersected 25 metres grading 0.30%
copper and 0.25 g/t gold starting at 147.5 metres. Drilling intersected low to moderately mineralized
Mount Polley breccia in 4 out of 5 of the holes and remains open in all directions. This zone intersected
mineralization consisting of monzonite to monzodiorite with weak to strong breccia textures and strong
reddening of potassium feldspar . The mineralization and geology are similar to the Southeast Zone
(previously mined Mount Polley deposit) located 650 metres southeast of the Gatehouse Zone target
along a geophysical trend.
The drill holes in the Wishbone Zone were on blind targets located near the Wight Pit, approximately
2,500 metres north-northeast of the mill. The targets were based upon geophysics, geology, structure and
soil geochemistry. Hole WB-24-264 intersected 4.86 metres grading 2.33% copper, 5.58 g/t gold and 12.18
g/t silver from 75.94 metres. Mineralization consisted of an intense magnetite and chalcopyrite breccia
that is very similar to the Boundary Zone (previously mined Mount Polley deposit).
The results of this exploration program will be assessed and follow up drilling considered.

reported were analysed at Bureau Veritas Mineral Laboratories in Vancouver. 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 informati on is
available to confirm the geological model and true width of significant assay intervals.
