Spartan Metals' Past Producing Rees Tungsten Mine delivers 6.76% and 8.48% WO3 and Reinforces the Eagle Project's Expanding Tungsten Potential
Spartan’s historic grade validation at Rees reinforces district potential ahead of an August drilling catalyst.
Spartan Metals Corp. announced rock chip sampling results from inside the past-producing Rees Tungsten Mine at its 100% owned Eagle Project in Nevada. New samples returned up to 6.76% WO3, closely aligning with historic United States Bureau of Mines (USBM) data showing grades up to 8.48% WO3. Rees is now the third past-producing mine at the Eagle Project where historic grades exceeding 1% WO3 have been validated.
Historic production records indicate approximately 1,306 short ton units shipped in 1954–1955 at an average grade of 3.51% WO3. The company outlined its 2026 exploration program, which includes continued surface sampling, geophysics evaluation, and approximately 3,000 meters of diamond core drilling scheduled for early to mid-August 2026. Management emphasized that the results reinforce the district-scale potential of the Eagle Project and highlight remaining underground infrastructure that could be reusable.
Spartan Metals Corp. released an update that validates historic high-grade tungsten mineralization, though it does not constitute a new resource estimate, production update, or financial result. The market has already priced in the district-scale exploration thesis following the March 2026 acquisition of the Victorio Project and subsequent land expansions.
The stock has consolidated since its March peak, reflecting a wait-and-see approach ahead of the planned August drilling and the Q4 2026 PEA for Victorio. Without a maiden resource estimate or economic study, this exploration update lacks the quantitative rigor required to materially re-rate the business.
Spartan Metals Corp. is a critical minerals explorer focused on tungsten, silver, and rubidium. Its primary asset is the Eagle Project in Nevada, a 36.5 km² property that includes past-producing mines such as Tungstonia, Rees, Antelope, and Yellow Jacket. The company also holds the Victorio Project in New Mexico, which it acquired in March 2026. This secondary asset features a historic 2012 resource of 77.2 million tonnes at 0.09% WO3 and 0.09% Mo. The company’s deposits are characterized by porphyry, skarn, and carbonate replacement (CRD) deposit types. Its strategic focus centers on U.S. critical mineral onshoring, Department of Defense partnerships, and tailings reprocessing.
