Spartan Metals Discovers Two New Tungsten-Silver Veins at
Tungstonia
Vancouver, Canada, June 16, 2026 – 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 veins at its Tungstonia Claims
within its 100% owned Eagle Tungsten-Silver-Rubidium Project, Nevada.
Highlights:
• Two new at surface quartz-huebnerite veins discovered by backpack core drill sampling approximately
1 kilometer (km) away from Vein 1 , which was the primary production vein at the past -producing
Tungstonia Mine
• Tungsten-silver mineralization is identical to mineralization within Veins 1 through 5 at the Tungstonia
Mine (Figure 1)
• Total of 7 tungsten-silver veins now confirmed including the new Spartan A and Spartan B veins

Brett Marsh, Spartan’s President and CEO, stated: “The discovery of additional vein systems at the Tungstonia
Claims represents an encouraging development for our exploration team and continues to reinforce our belief
that Eagle Project could potentially host a larger mineralizing system. The presence of multiple vein structures
across a broad area supports our geological model , confirms our rock chip and soils data, and highlights the
potential scale and expansion of the known mineralized footprint.
Mr. Marsh continued, “ What is particularly exciting is that these newly identified tungsten-silver veins
demonstrate that the mineralization extends beyond the areas historically recognized on the property.
Additionally, based on these results and those from our previous programs, we are enthusiastic that silver, which
wasn’t report in historic production with the tungsten, continues to be consistent in our sampling because we
believe it has the potential to add significant value to the project at current prices. As we continue our systematic
exploration program, we will focus on understanding the extent, continuity, and relationship of these veins and
associated mineralization across the project area. We look forward to advancing our exploration efforts and
evaluating the broader district-scale potential of the Eagle Project.”
The d iscoveries, part of the exploration program announced on May 21, 2026 , were confirmed utilizing a
portable backpack diamond core drill with a 36.4-millimeter (mm) diameter core. The backpack drill is intended
to rapidly evaluate potential veins and proposed drill locations prior to mobilization of larger diamond core drills.

vertical holes were located near potential vein locations interpreted from Spartan’s 2025 surface exploration

programs and collared in greisen altered granite. True thicknesses/widths of mineralization are unknown as
further definition is required to define the vein orientations.
The drill results validate the presence of previously interpreted but unconfirmed veins at the Tungstonia claims
and illustrate the potential for continued district scale discovery at the Eagle Project. The assay results are
consistent with previously reported production gra des at the Tungstonia and Yellow Jacket Mines of 0.6-0.9%
WO3(1) and 1.12% WO3(2), respectively, which further illustrates the tungsten potential at the Eagle Project.

m. Quartz with huebnerite was encountered from surface and exhibited similar characteristics to the mineralization observed in
Vein 1 near the Tungstonia Mine. Huebnerite crystals were approximately 1-2 centimeters (cm) in size (circled in white).

depth of approximately 1.22 m. Quartz with huebnerite was encountered from the surface and contained 3 -5 mm huebnerite
crystals (black specs) with multiple thin veinlets of huebnerite throughout the quartz.
Next Steps
Spartan will continue to execute its 2026 exploration program as discussed in the May 21, 2026, announcement
including:
• Continued surface sampling of soils and rocks – including continued backpack drilling – over claims
acquired in November 2025 to potentially extend previously identified tungsten, silver, and rubidium
soil anomalies
• Mid-June: Ground geophysics surveys to inform depths of existing 2+ km tungsten -silver veins and
potential tungsten skarn mineralization that is coincident with tungsten-silver-rubidium soil anomalies
• Early to mid-August: Approximately 3,000 meters (m) diamond core drilling at high priority targets
identified through surface sampling and geophysics surveys.
QA/QC Procedures
Samples were submitted to American Assay Lab (AAL) of Sparks, Nevada, which is a certified and accredited
laboratory, independent of the Company. Samples are prepared using industry standard -prep methods and
analyzed using method IM-4AB52 (52 element suite: 0.5g 4 -acid plus boric acid hot block ). AAL undertakes its
own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
Spartan’s QAQC includes regular insertion of CRM standards, duplicates, and blanks w ith a stringent review of
results completed by the Company’s Qualified Person, Brett 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 (1) high -
grade Tungstonia, Yellow Jacket, and Rees/Antelope tungsten (W-Cu-Ag) mines. Operations at these mines were
from 1915 to 1942 with intermittent small -scale production occurring until 1956. Tungsten production from
these mines totaled 8,379 units at grades between 0.6%-0.9% WO3
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 consisting 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 potential to recover W-Rb-Ag from the legacy Tungstonia
Mill Tailings.
