Spartan Metals Identifies High-Grade Silver-Rich CRD Target on Trend
with Tungstonia Vein System at the Eagle Project
Vancouver, Canada, November 3, 2025 – Spartan Metals Corp. (“Spartan” or the “Company”) (TSX-V: W)
is pleased to announce that it has identified a silver-rich Carbonate Replacement Deposit (“CRD”) target
on trend with the past producing Tungstonia Mine vein system at its 100% owned Eagle Tungsten-Silver-
Rubidium Project (“Eagle” or “Project”) in eastern Nevada.
Brett Marsh, Spartan’s President and CEO, states “When hydrothermal fluids moving along the structural
corridors interact with th ick, carbonate-rich sedimentary packages at the contact with the Tungstonia
Granite intrusion, we have the potential to develop an enriched depositional zone along preferred
limestone and dolostone beds, at structural intersections, and where we see veining in our host rocks. The
rock chip samples from 2024 returned several high-grade results that carry several of the primary metals
commonly associated with carbonate replacement deposit mineralization including silver, lead, copper,
and zinc. This strongly suggest s the potential for a larger carbonate r eplacement deposit that could
potentially contain significant critical metal concentrations at the Tungstonia Claim Block”
Mr. Marsh continues, “We are equally enthusiastic about the discovery of a n extensive vein system with
significant silver-copper-antimony that is continuing to develop at our Rees Claim block. The initial mapping
and surface sampling of the claim block appears to connect the former Antelope Mine to a series of veins,
breccias, and CRD mineralization located approximately 1.0 kilometer to the east of the mine itself . The
potential to discover bonanza grade silver at over 1,500 grams per tonne along with other critical metals
such as antimony, arsenic, and copper over an approximate 1-kilometer strike length makes the Eagle
Project a significant U.S. critical metal asset.”
Recent surface exploration and detailed review of previous surface rock chip sampling have identified high-
grade silver and base metal replacement mineralization that extends approximately 2.5 kilometers (“km”)
along the contact between the Tungstonia Granite intrusion and the limestone and dolostone host rocks
exposed to the south and south -west of the Tungstonia vein system. This mineralization occurs in
association with previously unidentified quartz veins in the Tungstonia Claim block with similar strike and
periodicity as veins observed in and around the past-producing Tungstonia Mine area (Figure 1).
Additionally, mapping and rock chip sampling at the Rees Claim block suggests a second potential CRD
system (Figure 2) where mineralization at the silver (“Ag”)-copper (“Cu”)-antimony (“Sb”) Antelope Mine
appears to be concentrated within a limestone-dolostone hosted vein system with tetrahedrite that is
orthogonal to an interpreted northeast structural corridor that extends approximately 1.0 kms.

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. Operations at these
mines were from 1915 to 1942 with intermittent small -scale production occurring until 1956. Tungsten
production from these two mines totaled 8,379 units at grades between 0.6%-0.9% WO3 (1).
The Project is ~20 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 4,936 acres consisting of 244 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.
