In a significant development for the mining industry, Spartan Metals Corp. has announced the discovery of two new tungsten-silver veins at its Tungstonia Claims within the Eagle Tungsten-Silver-Rubidium Project in Nevada. This discovery, made on June 16, 2026, represents a promising advancement for the company’s exploration efforts and underscores the potential of the Eagle Project.
The newly identified veins, named Spartan A and Spartan B were discovered approximately 1 kilometer away from Vein 1 the primary production vein at the past-producing Tungstonia Mine. The mineralization found in these veins is identical to that observed in Veins 1 through 5 at the Tungstonia Mine, confirming the presence of seven tungsten-silver veins in total within the project area.
Significant Findings and Assay Results
The discovery was made using a portable backpack diamond core drill with a 36.4-millimeter diameter core, which allowed for rapid evaluation of potential veins. The assay results for the new veins are promising, with notable grades of tungsten and silver. For instance, Spartan A exhibited a 9.51% WO3 and 1.3 g/t Ag over a 0.26-meter interval while Spartan B showed a 9.16% WO3 over a 0.57-meter interval.
Brett Marsh, President and CEO of Spartan Metals, expressed enthusiasm about the findings: “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 the Eagle Project could potentially host a larger mineralizing system.” He further emphasized the significance of the silver content, which was not reported in historic production, stating that it “continues to be consistent in our sampling and has the potential to add significant value to the project at current prices.”
Geological Context and Exploration Potential
The Eagle Project is situated in the Kern Mountains of White Pine County Nevada, covering an area of approximately 36.5 square kilometers. The project includes the past-producing TungstoniaYellow Jacket and Rees/Antelope mines, which operated from 1915 to 1942 with intermittent small-scale production until 1956. Historically, these mines produced 8,379 units of tungsten at grades ranging from 0.6% to 0.9% WO3.
The project area is characterized by three deposit types: porphyryskarn and carbonate replacement (CRD) which contain significant grades of tungsten, silver, and rubidium, along with other metals such as copper, antimony, bismuth, indium, lead, zinc, bismuth, and arsenic. The discovery of the new veins supports the geological model and confirms the rock chip and soils data, highlighting the potential scale and expansion of the known mineralized footprint.
Spartan Metals plans to continue its 2026 exploration program which includes continued surface sampling of soils and rocks, as well as backpack drilling over claims acquired in. Mid-June will see the commencement of ground geophysics surveys to inform the depths of existing veins and potential tungsten skarn mineralization. Additionally, early to mid-August will witness approximately 3,000 meters of diamond core drilling at high-priority targets identified through surface sampling and geophysics surveys.
The company has also engaged Global One Media Group Pte. Ltd. to support its digital investor communications strategy, aiming to increase market visibility and strengthen investor engagement. This engagement, commencing on July 1, 2026, involves the production and distribution of digital investor content, including video interviews and corporate communications.
As Spartan Metals continues to advance its exploration efforts, the discovery of the new tungsten-silver veins at the Eagle Project underscores the company’s commitment to developing critical minerals in well-established mining jurisdictions. The findings not only validate the presence of previously interpreted veins but also illustrate the potential for continued district-scale discovery at the Eagle Project.
