Scandium Canada Launches 4,000-Metre Diamond Drilling Program at Crater Lake

Scandium Canada Ltd. (TSX-V: SCD) announced the launch of its 2026 diamond drilling program at the Crater Lake scandium project in Nunavik, Quebec, comprising approximately 4,000 metres of drilling. The program primarily focuses on collecting a representative metallurgical bulk sample throughout the defined resource, complemented by resource extension drilling at the TG Zone and exploration drilling on the Discovery Zone. Camp mobilization has been underway since late April under the management of Laurentia Exploration, with drilling expected to begin in the coming weeks and continue through August 2026. In parallel, WSP will continue previous environmental assessment work from June to September in support of the prefeasibility study.

Of the planned drilling, 75% to 80% (approximately 3,000 to 3,500 metres) is dedicated to collecting a metallurgical test bulk sample of 8 to 10 tonnes throughout the defined resource and to testing its variability. Another 15% to 20% of the drill budget (500 to 1,000 metres) is allocated to exploratory resource augmentation drilling to test the lateral limits of the 2025 mineral resource estimate, which remains open. The remaining meterage will be used for limited shallow exploration drilling on the Discovery Zone, approximately 750 metres SSW along strike from the TG Zone resource. The environmental assessment work by WSP will continue from June to September.

CEO Guy Bourassa stated, 'With mobilization underway at Crater Lake, this program advances several priorities at once. The bulk of the drilling is dedicated to collecting a representative metallurgical bulk sample throughout the defined resource, the key input for the metallurgical work required for a feasibility study. We will also test the lateral extensions of the TG Zone, where the deposit remains open, and drill initial exploration targets on the Discovery Zone. We expect a steady flow of news from Crater Lake as results become available this fall.'

The 2026 campaign is built around three technical objectives. The core of the program is the metallurgical bulk sample, which will be assembled from half-diameter HQ drill core, assuming approximately 80% recovery over mineralized intercepts. The objective is to confirm grades and test the variability of the deposit from a metallurgical standpoint, providing material required for the metallurgical testwork supporting the future feasibility study. Resource extension drilling of 500 to 1,000 metres will test the lateral limits of the 2025 mineral resource estimate, which remains open, with the objective of demonstrating potential to expand the existing resource. A limited number of shallow exploration holes will test targets on the Discovery Zone, beyond the TG Zone which hosts the current prefeasibility work.

The Crater Lake project hosts a mineral resource estimate within the TG Zone, which remains open, as set out in the technical report entitled 'NI 43-101 Technical Report and Updated Mineral Resource Estimate for the Crater Lake Project, Quebec, Canada', available under the Company's profile on SEDAR+ at www.sedarplus.ca.

From June to September, WSP will continue the environmental assessment work initiated in 2024 at Crater Lake, including fauna and flora inventories, fish habitat surveys, and hydrogeological and geochemical studies, all in support of the environmental assessment underpinning the prefeasibility study. Field activities are conducted from the Company's existing exploration camp, with a maximum of 20 people on site and no new permanent installations. Laurentia Exploration manages camp logistics and the drilling campaign, with helicopter support for the movement of equipment and personnel.

Core samples will be shipped from site on outgoing flights to Laurentia's core facility, where QAQC standards will be inserted before samples are sent to Activation Laboratories (Ancaster, Ontario) for multi-element geochemical analysis. Mineralized intervals from the bulk sample will subsequently be selected on the basis of assay results and sent for LIBS scanning and metallurgical analysis. Assay results are expected in the fall of 2026. The Company will provide progress updates as the program advances.
