NOBLE MINERAL EXPLORATION INC. ANNOUNCES PHASE 2 SUMMER EXPLORATION PROGRAMS ON QUEBEC CRITICAL MINERALS PROJECTS

Noble Mineral Exploration Inc. has provided details on the next phase of the 2026 summer exploration season with surface exploration programs planned on its Chapiteau rare earth property in Labrador and the Mehmet rare earth property in Quebec, Canada. This phase will require helicopter support and will take place during the last week in June and the first week of July. Canadian Helicopters out of Goose Bay, Labrador, will provide helicopter support for the project.

The Chapiteau rare earth property, Labrador (see Noble's press release dated Nov. 25, 2025)

The Chapiteau rare earth property is a recently acquired rare earth element (REE) exploration property owned by Noble in western Labrador. The property was staked in late 2025 and consists of 25 map-staked units in one group and 18 map-staked units about 15 kilometres east. They lie in one of Canada's most prospective rare earth districts, about 100 kilometres south of the Strange Lake REE deposits and 38 kilometres northeast of the Crater Lake scandium/REE resource.

The property covers part of a large REE-enriched alkaline intrusive system first explored by Midland Exploration during 2010 to 2011. Midland completed a regional airborne magnetic and radiometric survey totalling more than 3,100 line kilometres and identified numerous REE targets associated with a large magnetic alkaline granite complex approximately nine kilometres in diameter. Regional sampling produced exceptionally strong results, including grab samples containing up to 8.34 per cent total rare earth oxides (TREO), heavy rare earth enrichment ranging from 2.29 per cent to 12.85 per cent heavy rare earth oxides (HREO) within mineralized samples, high values of cerium, lanthanum, neodymium, praseodymium, yttrium, dysprosium and gadolinium oxides. Within the ground now held by Noble, Midland identified six grab samples exceeding 0.5 per cent TREO, ranging from 1.4 per cent to 3.02 per cent TREO.

Only one known drill hole, Y3-11-04, was completed on the property. The hole tested the CP North showing and intersected coarse-grained alkaline granite with disseminated iron oxides and amphiboles. Although grades were modest, the entire hole returned anomalous REE values averaging approximately 0.14 per cent TREO plus Y2O3 (yttrium oxide), demonstrating a large mineralized system rather than isolated surface occurrences. Some intervals included:

• 0.13 per cent TREO plus Y2O3 over 7.5 metres;
• 0.14 per cent TREO plus Y2O3 over 12.0 metres;
• 0.16 per cent TREO plus Y2O3 over 7.5 metres.

Chapiteau is one of the more compelling early-stage REE acquisitions because it combines high-grade surface geochemistry, favourable alkaline intrusive geology and proximity to established critical mineral projects such as Strange Lake and Crater Lake.

Mehmet rare earth property, Quebec (see Noble's press release dated Nov. 5, 2025)

The Mehmet rare earth property is an early-stage rare metals and rare earth occurrence located in northeastern Quebec. According to Quebec's Sigeom mineral occurrence database, the property is classified as a hyperalkaline rare metals showing, a type of geological environment that can host rare earth elements, niobium, zirconium, tantalum, uranium and other critical minerals commonly associated with alkaline intrusive complexes and carbonatites.

One sample was found to contain a total of 2,157.1 parts per million rare earth elements, including 550 parts per million neodymium, 623 parts per million lanthanum, 483 parts per million fluorine and 1,027.3 parts per million cerium.

These systems are attractive because they can contain large-tonnage critical mineral deposits that are essential for electric vehicles, wind turbines, permanent magnets and advanced defence technologies.

H. Vance White, president and chief executive officer, said, "We are pleased to get this program under way in order to determine the expected follow-up programs later this summer and early fall."

Wayne Holmstead, Quebec PGeo (No. 10434), a qualified person as such term is defined by National Instrument 43-101, has verified the data disclosed in this news release and has otherwise reviewed and approved the technical information in this news release on behalf of Noble.

About Noble Mineral Exploration Inc.

Noble Mineral Exploration is a Canadian-based junior exploration company, which has holdings of securities in Canada Nickel Company Inc., Homeland Nickel Inc. and East Timmins Nickel Inc. (20 per cent) and its interest in the Holdsworth gold exploration property in the area of Wawa, Ont.

Noble holds mineral and/or exploration rights in approximately 70,000 hectares in Northern Ontario and approximately 25,000 hectares elsewhere in Quebec, upon which it plans to generate option/joint venture exploration programs. Among those are included Noble's mineral rights and/or exploration rights in 18,000 hectares in the Timmins-Cochrane areas of Northern Ontario known as Project 81, approximately 2,215 hectares in Thomas township/Timmins, and an additional 20-per-cent interest in approximately 38,700 hectares in the Timmins area held by East Timmins Nickel. Project 81 hosts diversified drill-ready gold, nickel-cobalt and base metal exploration targets at various stages of exploration. Noble's holdings in Ontario also include approximately 4,600 hectares in the Nagagami carbonatite complex and approximately 3,200 hectares in the Boulder project, both near Hearst, Ont. In Quebec, it holds approximately 3,700 hectares in the Buckingham graphite property; approximately 10,152 hectares in the Havre St. Pierre nickel/copper/platinum group metal property; approximately 1,573 hectares in the Cere-Villebon nickel/copper/PGM property; the approximately 569-hectare Chateau uranium/rare earth property; the approximately 461-hectare Taser North uranium/molybdenum property; the approximately 4,465-hectare Mehmet REE property; the approximately 3,300-hectare Gull Lake REE property; and the approximately 1,232-hectare Opawica scandium and REE property. In Newfoundland and Labrador, it holds the approximately 647-hectare Chapiteau REE property.
