Noble Minerals Acquires a Rare Earth Property in Labrador

(TheNewswire)

Toronto, Ontario November 25, 2025 TheNewswire - Noble Mineral Exploration Inc. ( "Noble" or the "Company" ) (TSX-V:NOB, FRANKFURT: NB7, OTCQB:NLPXF) is pleased to announce the acquisition through map staking of a rare earth element ("REE") enriched system on its Chapiteau Property located 100 kilometers south of the Strange Lake and B-Zone deposits and 38 kilometers northeast of the Crater Lake Scandium-Rare Earth resource.  The Labrador property consists of 25 map staked units for a total of approximately 647 hectares (Figure 1 and 2).

The property covers ground explored by Midland Exploration Inc (Midland) in 2010/2011.  During this time, Midland, completed a 3,143-line-kilometer airborne magnetic and radiometric survey that identified several new exploration targets for REEs.  With the results of the airborne survey, the Midland team prospected and sampled the exposed portions of these magnetic and radiometric anomalies. Regionally, the results from selected samples from 81 rock outcrops and locally derived and mineralized boulders returned very high values of up to 8.34% rare earth element oxides (TREOs), including yttrium. The proportion of heavy rare earth element oxides (HREOs) ranged from 2.29% to 12.85% HREO for samples containing more than 0.5% TREO. Analysis of individual REEs yielded significant results up to 8.22% cerium oxide (Ce2O3), 3.38% lanthanum oxide (La2O3), 3.39% neodymium oxide (Nd2O3), 0.66% yttrium oxide (Y2O3), 0.96% praseodymium oxide (Pr2O3), 0.19% dysprosium oxide (Dy2O3), and 0.35% gadolinium oxide (Gd2O3).

Regionally, the best concentrations of mineralization are associated with iron oxides nested in pegmatite-aplite dikes and plurimetric iron oxide clusters disseminated in an intrusion interpreted as an alkaline granite. Grab samples from twenty-six new mineralized areas returned values ranging from 1.02% to 8.34% TREO. The alkaline granite hosting this mineralization manifests itself as an airborne magnetic anomaly 9 kilometers in diameter.

On the property recently staked by Noble, six grab samples greater than 0.5% TREO were located by Midland.  They ranged from 1.40 to 3.02% TREO with:

• 0.29 to 0.79% lanthanum oxide (La2O3),

• 0.60 to 1.48% cerium oxide (Ce2O3

• 0.06 to 0.14% praseodymium oxide (Pr2O3)

• 0.23 to 0.45% neodymium oxide (Nd2O3),

• 0.02 to 0.10% yttrium oxide (Y2O3)

• 0.006 to 0.02% dysprosium oxide (Dy2O3)

• 0.02 to 0.03% gadolinium oxide (Gd2O3)

A series of channel samples and one diamond drill hole (Y3-11-04) were completed on the Chapiteau property in 2011. (see Fig 3, 4 and 5).

Drill hole Y3-11-04 was aimed at the CP North Showing. The hole intersected a grey-pink coarse grained alkaline granite with 2-3% disseminated iron oxides and amphiboles. A total of 29 samples varying in length from 1 to 1.5 meter were collected. All collected samples returned anomalous TREO + Y2O352 values averaging 0.14% TREO + Y2O3 ranging from 0.11 to 0.19% TREO + Y2O3. The best assay results returned 0.13% TREO + Y2O3 over 7.5m from 25.0 to 32.5 meters, 0.14% TREO + Y2O3 over 12.0 m from 38.0 to 50.0 meters and 0.16% TREO + Y2O3 over 7.5 m from 64.0 to 71.5m.

The Chapiteau Property is located about 38 km northeast of the Crater Lake Property where Scandium Canada has defined a rare earth and scandium resource. (See Chart 1)
