Scandium Canada drills 140.15 m at 293 ppm Sc2O3 at Crater Lake

HIGHLIGHTS

Hole CLB26076 intersected 140 metres of scandium mineralization at 293 ppm Sc₂O₃, the longest intercept of the 2026 program, including a 30-metre high-grade section at 512 ppm;

Three holes have now returned more than 100 metres of continuous mineralization each: CLB26076 (140 m), CLB26072 (125 m, reported in August) and CLB26080 (102 m);

All 12 holes reported to date hit scandium mineralization, at grades in line with the current resource estimate. The deposit is delivering what the model predicted;

A total of 15 holes have been drilled to date confirming the presence of favourable scandium bearing lithologies at the North and South lateral extensions of the TG deposit potentially extending the mineralized zones by 245 metres;

A total of 5 exploration holes have confirmed mineralization to the North and South of the TG deposit;

Two exploration drill holes in Discovery Area intercepted two narrow pyroxene-rich ferrosyenites (PXFESYN) of up to 1 m thick at depth. Assay results are pending;

Drilling campaign expected to be completed by October 13 and final drill core samples to be sent to the labs by mid-October, 2026.

Quebec City, Québec--(Newsfile Corp. - September 23, 2026) - Scandium Canada Ltd. (TSXV: SCD) (the "Company") is pleased to announce additional assay results from the 2026 diamond drilling program at its Crater Lake scandium project in Nunavik, Québec.

The Company has received the assay results from an additional 9 holes collared to extract a bulk sample from the TG deposit. Every hole drilled for that purpose and reported to date intersected the targeted lithologies and mineralization, namely scandium-bearing olivine-rich or pyroxene-rich ferrosyenites, at grades consistent with those of the mineral resource estimate (MRE 2025) of the TG deposit.

As of September 22 nd , a total of 40 hole
