Investing in Spartan Metals offers a unique opportunity to gain exposure needed to high-grade tungsten and other critical metals in the Western United States.

Spartan Metals is focused on developing critical minerals projects in well-established and stable mining jurisdictions in the western United States, with an emphasis on building a portfolio of strategic defense minerals including tungsten, rubidium, antimony, bismuth and arsenic.

Spartan’s high quality project portfolio includes an option to earn 100% of the Victorio Tungsten-Molybdenum Project in New Mexico and its 100% owned Eagle Tungsten-Silver-Rubidium Project in Nevada.

Victorio is an advanced exploration project that hosts a 2012 historical mineral resource estimate of tungsten-molybdenum mineralization, with beryllium and fluorspar also present; an updated mineral resource estimate and preliminary economic assessment are in progress.

A qualified person has not done sufficient work to classify the Victorio historical estimate as current mineral resources or mineral reserves, and Spartan is not treating the historical estimate as current mineral resources or mineral reserves. See the Company’s news release of March 17, 2026 and www.spartanmetals.com for the source, date, parameters and reliability of the historical estimate.

Eagle is a district containing three past-producing high-grade tungsten mines (Tungstonia, Rees and Yellow Jacket) where Spartan’s sampling has also identified silver, rubidium, antimony, bismuth and indium mineralization. No mineral resource has been estimated at Eagle.

Backed by a seasoned exploration team, strong Department of Defense relationships, and strategic partnerships, Spartan is positioned to advance valuable mineral projects while minimizing risk and maximizing growth.
