Scandium Canada's Scalium+ Advancing Its Al-Sc Alloy Under Canadian Space

Agency R&D Contribution to Reduc e Mass of Components in Space

Applications

MONTRÉAL (QUÉBEC) – Scandium Canada Ltd. (TSX-V: SCD) (the “Company”)

announces that its wholly owned subsidiary Scalium+ is advancing the adaptation of

the Scalium® aluminum-scandium alloy for space applications, notably next-

generation Canadian satellites, under an existing contribution agreement with the

Canadian Space Agency ("CSA"). The agreement provides a non-repayable

contribution of $348,750 supporting a project that extends to May 31, 2028.

Alloy to Reduce Mass of Components in Space Applications

The funded project, titled "Proof of Concept of Innovative High-Strength Aluminum

Alloy to Reduce Mass of Components in Space Applications," aims to adapt Scalium®,

an ultra-strong aluminum-scandium alloy currently produced in thin sheets, into thick

plates suitable for aerospace needs.

Following successful initial l aboratory tests, the work program focuses on scaling up

manufacturing, validating the alloy's performance, and demonstrating its use for next-

generation Canadian satellites. Scalium® could help reduce launch costs, lower

carbon emissions, and allow spacecraft to carry more valuable equipment.

The project is conducted under the CSA' s Space Technology Development Program

(STDP), Announcement of Opportunity 9.2, Space Research and Development, Small

Businesses. This project is undertaken with the financial support of the Canadian

Space Agency.

The Agreement

The contribution agreement was originally signed on August 29, 2025, between the

CSA and Ferreol Technologies, prior to its acquisition by Scandium Canada,

completed on June 29, 2026. On August 17, 2026, the CSA signed an amendment,

formally confirming Scalium+ as beneficiary of the agreement and noting that the

management team, mission, technologies and business relationships of the

beneficiary remain unchanged. The project continues under the agreement's existing

terms.

"The CSA's confirmation of Scalium+ as beneficiary reflects the continuity we

committed to when we first signed this agreement, and work continues without

interruption," said Félix Lapointe, Chief Executive Officer (CEO) of Scalium+.

"Adapting Scalium® from thin sheet to thick plate is a defined technical program with

clear milestones through 2028, carried out by our team in Québec, and it advances

Scandium Canada's mine-to-alloys strategy."

"Space is one of the main application areas we are targeting for our aluminum-

scandium alloys, alongside aeronautics, defence, transportation and sporting goods,

and it is one of the sectors where every kilogram saved carries the most value for

OEMs. Canada’s space industry has a world-class reputation, and Québec is home to

some of its most innovative players. Our ambition is for the Canadian and Québec

OEMs designing the next generation of sa tellites and space systems to have access

to a high-performance aluminum-scandium alloy sourced from a local supply chain.

We thank the Canadian Space Agency for its support and the professionalism of its

team on this project," said Simon Thibault, President & Chief Executive Officer of

Scandium Canada and President of Scalium+.

About Scalium+

Scalium+, formerly Ferreol Technologies , is Scandium Canada’s wholly owned

commercialization subsidiary for aluminum-scandium (Al-Sc) alloys. It unites the alloys

developed by the Company’s Scandium+ division with the Scalium® line of alloys and

surface treatment created by the Ferreol Technologies team. Scalium® alloys add

value on multiple fronts: significantly higher mechanical strength than conventional

alloys in rolled products, better weldability in wire form, faster print speeds in powder

form, and much higher corrosion resistance. For manufacturer s, this translates into

lighter parts, shorter build times in additive manufacturing and better lifetime value for

primary and secondary components. Scalium+ brings these specialized materials to

market today, across multiple sectors.

About Scandium Canada Ltd.

Scandium Canada (TSX-V: SCD) is a critical advanced materials company developing

North America’s only vertically integrated primary source of scandium, from its Crater

Lake project in Nunavik, Québec, to aluminum-scandium (Al-Sc) alloy products.

Through Scalium+, its wholly owned commercialization subsidiary, the Company

brings proprietary, patent-pending Al-Sc alloys and the Scalium® line of alloys and

technologies to market today, while advancing the Crater Lake mining project for the

future. This dual-engine strategy positions Scandium Canada to anchor a secure,

resilient North American scandium supply chain and to shape the future of lighter,

stronger and longer-lasting materials for advanced manufacturing end users, while

committing itself to building a more responsible economy through innovation and

agility.

information" within the meaning of applicable Canadian securities legislation. Forward-

looking statements in this press release include, without limitation, statements relating

to: the continuation and expected completion of the project funded under the

contribution agreement with the Canadian Space Agency, including its milestones

through May 31, 2028; the adaptation of the Scalium® alloy from thin sheets into thick

plates suitable for aerospace needs; the scale-up of the related manufacturing

process; the validation of the alloy's performance and the demonstration of its use for

next-generation Canadian satellites; the potential benefits of the alloy for space

applications, including reduced launch cost s, lower carbon emissions and increased

capacity for spacecraft to carry equipment; the potential application of the Company's

alloys to other sectors, including aeronautics, defence, transportation and sporting

goods; the Company's ambition to supply Canadian and Québec original equipment

manufacturers; the advancement of the Company's mine-to-alloys strategy, including
