Toronto, Ontario – TheNewswire - May 11, 2026 – Noble Mineral Exploration Inc. (“Noble” or the “Company”) (TSX-V:NOB, FRANKFURT: NB7, OTCQB:NLPXF Noble Mineral Exploration Inc. (“Noble” or the “Company”) is pleased to announce the commencement of its Phase 1, 2026 summer exploration season with surface exploration programs planned on its Gull Lake Rare Earth Element (“REE”) property and the Scandium Property in Quebec, Canada.

Gull Lake Rare Earth Property (See Noble Press Release November 17, 2025)

The Gull Lake Property, located in north-central Quebec, consists of two claim blocks strategically positioned approximately three kilometers east and west of the Montviel Carbonatite-hosted Rare Earth Element deposit. The property is road accessible.

The Montviel deposit, owned by Geomega Resources Inc., represents one of North America’s largest bastnaesite-hosted rare earth element resources. The deposit is also enriched niobium, neodymium and praesidium has become an important strategic critical minerals project in Quebec.

Noble’s summer exploration program at Gull Lake will include prospecting, geological mapping, sampling, and reconnaissance-scale evaluation of prospective carbonatite and alkaline intrusive targets associated with the regional Montviel intrusive complex. The Company believes the proximity of its claims to the Montviel deposit provides excellent potential for the discovery of additional REE-bearing carbonatite systems.

The 2026 exploration campaign is designed to advance priority target areas identified through compilation of historical geological information, regional geophysical datasets, and interpretation of favorable structural and lithological trends associated with carbonatite-hosted rare earth mineralization.

Management of Noble believes the growing demand for critical minerals, including rare earth elements used in electric vehicles, renewable energy technologies, advanced electronics, and defense applications, continues to strengthen the long-term exploration potential of strategically located and road accessible Quebec REE projects.

Scandium Property, Quebec (see Noble Press Release March 16, 2026)

The Scandium Property consists of 22 claims totaling approximately 1,232 hectares located approximately 90 kilometres southwest of Chibougamau. The property is road accessible

A review of historic Quebec government geochemical data from Report MB 90-01 identified multiple anomalous scandium and rare earth element values from rock samples collected during a 1986 government survey. The property covers basalt (V3B) and tonalite (I1D) lithologies associated with elevated scandium and a suite of critical metals including niobium, thorium, beryllium, germanium, vanadium, copper, manganese, and total rare earth elements.

Scandium values up to 530 ppm (813 Sc2O3) were detected in Tonalitic/Basaltic lithologies.

Management believes the presence of multiple anomalous scandium occurrences across several lithologies within the same district may indicate a broader mineralized system with potential for critical metal enrichment.

Scandium is considered a strategic critical mineral due to its use in high-strength aluminum alloys, aerospace applications, solid oxide fuel cells, and advanced technologies. The association of scandium with rare earth elements and high-field-strength elements such as niobium and thorium may indicate the presence of a fertile intrusive or magmatic system capable of hosting significant critical mineral mineralization.

“Noble is pleased to begin its summer field programs on highly prospective critical mineral projects in Quebec and Labrador,” stated Vance White, President and CEO of Noble minerals.

The Company will provide further updates as exploration progresses and analytical results become available.

Following the Phase 1 program, Noble will commence Phase 2 exploration on the following Projects:

The Chapiteau Rare Earth Property, Labrador (See Noble Press Release November 25, 2025)

And the Mehmet Rare Earth Property, Quebec ((See Noble Press Release November 5, 2025)
