Canterra Minerals intersects 144m of 0.75% CuEq at Lundberg

Buchans Summer Drill Program Highlights:

Lundberg Deposit - Broad Near-Surface Stockwork Intercept: Hole H-26-3568 returned 144.0m of 0.75% CuEq from 64.0m (0.26% Cu, 1.32% Zn, 0.73% Pb, 2.6 g/t Ag and 0.04 g/t Au), including 76.0m of 1.00% CuEq and 18.0m of 1.56% CuEq (0.38% Cu, 3.21% Zn, 1.85% Pb, 5.84 g/t Ag and 0.073 g/t Au) at the top of the interval.¹² The vertical infill hole was drilled between historical holes H-0175, H-0022 and H-0072 (incomplete historical assays) and demonstrates continuity of mineralization through a broad interval of the Lundberg stockwork system.

Lundberg Deposit - Infill and Grade Definition: Hole H-26-3564 returned 5.0m of 0.39% CuEq from 77.0m, and 12.25m of 0.28% CuEq from 126.0m, including 9.0m of 0.32% CuEq. The hole filled a near-surface gap in the deposit and tested continuity of copper mineralization intersected in historical drilling.

Regional Exploration - Horseshoe Target Drill Tested: Two holes totalling 575 metres tested a previously undrilled, approximately 900-metre strike-length SkyTEM conductor at Horseshoe, 10.6 km southwest of the Lundberg Deposit, and returned no significant values. The geophysical response is attributed to pervasive chlorite alteration, a common and important alteration feature in VMS footwall alteration zones.

Lundberg Mineral Resource Estimate Remains on Track: The Company continues to target delivery of a Mineral Resource Estimate (“MRE”) for the Lundberg Deposit in Q4 2026. This will be the first Lundberg MRE prepared under Canterra’s direction and the first to incorporate the Company’s 2024-2026 drilling.

Lemarchant Deposit - Resource Expansion, Greenfields and Geophysical Targeting: Phase 2 drilling is underway at Lemarchant, the largest of Canterra’s satellite deposits in the Buchans District. Drilling is focused on extensions and infill in and around the existing mineral
