Spartan Metals IdenƟfies Two New Tungsten-Silver-Rubidium Targets

at its Eagle Project, Nevada

Vancouver, Canada, December 9, 2025 – Spartan Metals Corp. (“Spartan” or the “Company”) (TSX-V: W |

OTCQB: SPRMF | FSE: J03) is pleased to announce the discovery of two new tungsten-silver-rubidium

exploraƟon targets at the Tungstonia deposit part of the company’s 100% owned Eagle Tungsten-Silver-

Rubidium Project (“Eagle” or “Project”) in eastern Nevada.

Highlights:

 Soil samples taken provided near complete coverage of the original Tungstonia and Rees claim

blocks on 100-meter (“m”) x 100m grid totalling approximately 2,100 samples covering about 20

square kilometers (“km2”).

 Encouraging grades in soil at Tungstonia suggest near-surface mineralizaƟon included:

o Tungsten up to 272 parts per million (“ppm”) with 76 samples over 50 ppm

o Silver up to 5.9 grams per tonne (“g/t”) with 57 samples over 1.0 g/t

o Rubidium up to 537 ppm with 56 samples over 300 ppm

 Discovered two new exploraƟon targets:

o Significant ~2.0 km x ~1.7 km anomaly outlined by coincident tungsten-silver-rubidium

enrichment on western por Ɵon of Tungstonia claims that follows the same structural

trends and spacings observed at the legacy past-producing Tungstonia mine

approximately 1.5 km to northwest

o SubstanƟal ~0.75 km x ~2.1 km anomaly in southeast por Ɵon of Tungstonia claims

trending southeast

 AddiƟonal soil sampling planned to extend to the boundary of the newly staked Tungstonia claims

Soil sample results from the 2025 surface geology program that commenced on October 16, 2025, have

outlined an approximate 2.0 km x 1.7 km surface anomaly that is aligned with regional trends observed at

past-producing Tungstonia Mine and a second 0.75 km x 2.1 km surface anomaly in the southeast porƟon

of the Tungstonia claims that confirm mapped veins and structured iden Ɵfied earlier this year . The soil

results from the Rees block did not yield any new targets. The results of the soil sample program will help

generate drill targets for a spring 2026 drill program.

BreƩ Marsh, Spartan’s President and CEO, states, “These soil results are very exciƟng as they validate our

exploraƟon model and generate important steps toward defining drill targets at Tungstonia. We iniƟated

our surface explora Ɵon program with two key objec Ɵves; to extend the known veins at the legacy

Tungstonia mine, and to define new veins in the western por Ɵon of the Tungstonia Claim block. I believe

the results of the hard work completed by our team has successfully met those objecƟves.”

Mr. Marsh conƟnues, “The strength and extent of the anomalies — in some cases exceeding those observed

around the past-producing Tungstonia mine — highlight the poten Ɵal for a significantly larger mineral

system than historically recognized. These new targets strengthen Spartan’s posiƟon within the U.S. criƟcal

minerals onshoring landscape. Our team is eager to conƟnue working with our data to generate

meaningful drill targets for a drill program in the spring of 2026.”

is aligned with the north-northeasterly structural trend observed at the legacy Tungstonia mine. The

Southeastern Tungsten Anomaly appears to coincide with intrusive contacts with carbonaceous sediments

that could extend further to the southeast. Note that the soil results in these anomalies appears to be

stronger than those obtained from the known Tungstonia mine area suggesƟng significant new exploraƟon

potenƟal (Figure 1).

those obtained from the known Tungstonia mine area sugges Ɵng significant new explora Ɵon potenƟal

(Figure 2).

appears to be stronger than those obtained from the known Tungstonia mine area sugges Ɵng significant

new exploraƟon potenƟal (Figure 3).

Significance of Soil Results

Soil sampling is typically used at early stages of exploraƟon to quickly idenƟfy geochemical anomalies that

can indicate underlying mineraliza Ɵon, veins, favorable altera Ɵon, or to help understand geological

controls such as, structural trends. Soils form from breakdown of underlying rock and higher grades

(hundreds of parts per million or several grams per tonne) can be indica Ɵve of mineralizaƟon near the

surface and increase confidence that the idenƟfied anomalies are genuine. Tungsten, silver, and rubidium

at the Tungstonia claims show overlapping elevated values that are reasonably well aligned regional

structural trends that control mineralizaƟon at the legacy Tungstonia mine, so the newly defined targets

are potenƟally material and could be significant addiƟons to the mineralizaƟon at the Tungstonia deposit.

AddiƟonally, the soil results in these two anomalous areas appear to have a stronger signature that what

was returned over the legacy past-producing Tungstonia mine area. This is potenƟally indica Ɵve of

meaningful tungsten, silver, and rubidium mineralizaƟon in these large areas.

QA/QC Procedures

Samples were submi Ʃed to American Assay Lab (AAL) of Sparks, Nevada, which is a cer Ɵfied and

accredited laboratory, independent of the Company. Samples are prepared using industry standard-prep

methods and analyzed using method IO-4AB51 (51 element suite: 0.5g 4-acid plus boric acid hot block,

ICP-OES plus IM-4ABEx ICP-MS for Rb. AAL undertakes its own internal coarse and pulp duplicate analysis

to ensure proper sample prepara Ɵon and equipment calibra Ɵon. Spartan’s QAQC includes regular

inserƟon of CRM standards, duplicates, and blanks with a stringent review of results completed by the

Company’s Qualified Person, BreƩ R. Marsh, President and CEO of Spartan Metals.

About The Eagle Project

The Eagle Project presents a unique opportunity to delineate one of the largest and highest-grade

Tungsten (“W”) and Rubidium (“Rb”) districts in the United States. The Project consists of the past-

producing high-grade Tungstonia and Rees/Antelope tungsten (W-Cu-Ag) mines. Opera Ɵons at these

mines were from 1915 to 1942 with intermi Ʃent small-scale produc Ɵon occurring un Ɵl 1956. Tungsten

producƟon from these two mines totaled 8,379 units at grades between 0.6%-0.9% WO3 (1).

The Project is ~36.5 km² in size and located approximately 120 kilometers northeast of the town of Ely, in

the Kern Mountains of White Pine County, Nevada. The Project covers 9,033 acres consisƟng of 445 Bureau

of Land Management (BLM) unpatented lode mining claims.

Three deposit types are present at Eagle; Porphyry, Skarn, and Carbonate Replacement (CRD) that contain

significant or anomalous grades of Tungsten (W), Silver (Ag), and Rubidium (Rb) plus Cu-Sb±Au-Pb-Zn-Bi-

As across three project focus areas that also includes the potenƟal to recover W-Rb-Ag from the legacy

Tungstonia Mill Tailings.
