Spartan Metals Provides Assay Results and Project Updates for the
Eagle Property
Significant High-Grade Tungsten and Silver Mineraliza8on Verified at Tungstonia Project.
Vancouver, Canada, August 7, 2025 – Spartan Metals Corp. (“Spartan” or the “Company”) (TSX-
V: W) is pleased to provide assay results and project updates for its recently closed acquisiEon
of the Eagle Property (the “Property”) announced on July 31, 2025. The Eagle property
comprises 244 lode mineral claims in White Pine County, Nevada (Figure 1). The Property is
100% owned by the Company.
The Property is a tungsten-copper porphyry and skarn system which hosts one of the highest-
grade past producing tungsten districts in the United States with the Tungstonia and Rees mine
operaEons historically producing a reported 8,352 tonnes of tungsten trioxide (WO3) at average
grades of 0.6-1.0% between 1917-19561. The Property also exhibits significant concentraEons of
rubidium, copper, silver, anEmony as well as lesser lead and zinc, which is interpreted as part of
the larger metal zonaEon paaern of the porphyry system across the district.
William Pe)grew, Spartan’s, CEO commented, “We were excited to conduct field reconnaissance
and rock chip sampling for the purposes of verifying historic data and results from Ridgeline
Minerals Corp’s 2024 rock chip sampling program as well as tesHng mineralizaHon at previously
unreported locaHons at Tungstonia. The results confirm the historic and previous work and
provide new data approximately 200-400m down strike from historic producHon locaHons at
Tungstonia”.
Mr. Pe)grew conHnues, “These encouraging results validate historic and previous sampling and
highlight the potenHal for the Eagle Property to be a significant source of tungsten, rubidium,
anHmony, silver, and copper in the future. We look forward to conHnuing field acHviHes at the
Tungstonia and Rees Projects and developing the Project further.”

Tungstonia Project
Currently known tungsten mineralizaEon occurs in 5 historically mined quartz-huebnerite
(MnWO4) veins – named Veins 1 through 5 - hosted in granite. A total of 6 rock chip samples
were taken at Tungstonia. Three samples were intended to validate results obtained by
Ridgeline Minerals (RDG) in 2024 at Veins 1 and 2, which were the primary historically mined
veins. The remaining three samples were focused on historically mapped but unsampled Vein 3
and 4 locaEons. All samples were taken at surface.
Figures 2 and 3 illustrate the RDG and Spartan sample locaEons with corresponding assay
results. Ridgeline results indicated 0.54% WO3 and 13.5 g/t Ag at Vein 1 and 1.49% WO3 and
50.5 g/t Ag at Vein 2. Spartan results for Vein 1 were 1.97% WO3 and 308 g/t Ag (TS-25001) and
for Vein 2 were 1.36% WO3 and 31.9 g/t Ag (TS-25002) and 1.88% WO3 and 12.5 g/t Ag (TS-
25003). Spartan samples at both veins were taken within 10m of the RDG samples and the
resulEng assays validate the previous work.
Veins 3 and 4 were sampled extensively via trenching by the US Bureau of Mines (USBM) in
about 1942 and associated surface mapping indicated these veins extended approximately
400m to the southwest but did not have reported assays. Spartan’s acEviEes focused on tesEng
the mapped but unsampled locaEons. Assays for Vein 3 were 2.37% WO3 and 9.6 g/t Ag (TS-
25005) and 1.54% WO3 and 0.9 g/t Ag (TS-25006) with Vein 4 sample returning 0.92% WO3 and
5.1 g/t Ag (TS-25004)
These samples clearly verify the historic and Ridgeline results and further demonstrate the high-
grade tungsten mineralizaEon at the Tungstonia Project.

Figure 3 Close up view of Spartan (purple) and RDG (black)sampling at similar locations. Previous USBM trench left significant
lengths of Veins 3 and 4 unsampled. Spartan’s sampling at the southernmost extent of mapped/unsampled veins confirms high-
grade tungsten and silver mineralization up to 400m away from the previous USBM activity.
QA/QC Procedures
Rock chip samples were taken by hand with rock hammer across veins to obtain an approximate
2-kilogram sample. Samples were submiaed to American Assay Lab (AAL) of Sparks, Nevada,
which is a cerEfied 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 digesEon/ICP-OES or ICP-MS with 4AB ore grade for
overlimit W samples) and IM-NFEx for W . AAL undertakes its own internal coarse and pulp
duplicate analysis to ensure proper sample preparaEon and equipment calibraEon. Spartan’s
QAQC includes regular inserEon of CRM standards, duplicates, and blanks with a stringent
review of results completed by the Company’s Qualified Person, Brea R. Marsh, President,
Spartan ExploraEon Nevada.
