Vault Strategic Commences Exploration at War Bond Historical Tungsten Mine, Nevada

(TheNewswire)

Vancouver, British Columbia - May 29th, 2026 - Vault Strategic Mining Corp. (TSXV: KNOX) (OTC: KNXFF) (FSE: M850) (WKN: A41WE4)  ("Vault" or the "Company") is pleased to announce that a team has been deployed and exploration is now underway at the War Bond Tungsten Project (“War Bond”) which includes the Historical War Bond Tungsten Mine, Historical Tactite Tungsten Mine and Historical Thursday Tungsten Mine located  in Nevada, USA.

Nevada was ranked as the number one mining jurisdiction in the Fraser Institute’s Annual Survey of Mining Companies released on February 26th, 2026.1

“Exploration work toward disciplined drill target generation is now underway at War Bond, representing an exciting opportunity for Vault to apply modern exploration methods to a historical tungsten district in Nevada,” said Quinn Field-Dyte, Chief Executive Officer of Vault Strategic Mining Corp. “We are excited to have fieldwork underway across the War Bond, Tactite and Thursday historical tungsten mine areas. Nevada is a premier mining jurisdiction with a long mining history, established infrastructure and a supportive exploration environment. Our immediate objective is to verify and consolidate the historical information, complete field validation work and advance the project toward disciplined drill target generation.”

Maiden Exploration Program

The proposed field program, which the Company is fully funded to execute on, will focus on modern geological evaluation of the historical War Bond tungsten system. The proposed scope includes:

• Detailed mapping of the intrusive-carbonate contact and skarn zoning, including garnet, epidote, and scheelite-bearing zones;  

• Underground and surface verification of historical zones, including accessible workings and mine dumps;  

• Channel sampling across tactite and adjacent structures, with appropriate QA/QC procedures;  

• Portable ultraviolet work to evaluate scheelite distribution and continuity;  

• Structural measurements to help constrain mineralized controls, plunge, and potential extensions; and  

• Development of high priority drill targets, including coordinates, sections, and conceptual collar locations.

The War Bond claim package consists of 20 unpatented lode mining claims, covering approximately 400 acres, located in Delaware Mining District of western Nevada. The land package includes the historical War Bond Tungsten Mine, the Tactite and Thursday historical tungsten workings, and the Alex Eske historical tungsten mine area.

The War Bond Tungsten Project includes the historical War Bond, Tactite and Thursday tungsten mine areas in western Nevada. Available online historical records appear to treat War Bond, Tactite, Thursday, Old Discovery and Knight Claims as related or overlapping property names within the same broader tungsten occurrence area, rather than as fully separate modern projects. Western Mining History's MRDS-derived War Bond Mine record identifies War Bond Mine as a tungsten mine in Douglas County, Nevada, and lists Tactite and Thursday, Old Discovery and Knight Claims as secondary names.2

Figure 3. Historical War Bond, Tactite and Thursday Tungsten Mines Claim Map

A separate MRDS-derived War Bond Tungsten Mine record identifies Tactite & Thursday, Old Discovery Claim, Knight Claims, Tungsten Valley Claim, Yellow Problem Claim and Margret Claim as related secondary names. That record also identifies Carson Tungsten Co. as owner, with an information year of 1952, and lists the operation category as past producer.3

Historical descriptions indicate that tungsten mineralization in the area is associated with scheelite-bearing tactite or skarn developed near granite-limestone contacts. The Nevada Bureau of Mines and Geology publication Mineral Resources of Douglas, Ormsby, and Washoe Counties describes the Tactite Thursday claim as located about 15 miles southeast of Carson City in Section 9, T. 14 N., R. 21 E., and states that scheelite occurs in a small tactite area near a granite-limestone contact.4

The MRDS-derived Tactite Thursday record describes the occurrence as a W skarn with scheelite as mineral and epidote, garnet, quartz and calcite as gangue minerals. The same record reports two principal mineralized areas, including a west zone with scheelite in narrow widths up to 0.3% WO3 and an east zone where scheelite is reported in small shoots with values ranging from 0.25% to 0.45% WO3 over widths of 4 to 8 feet.5

Historical assay and laboratory records in the Nevada Bureau of Mines and Geology Digital Library file titled Preliminary Examination of Tactite and Thursday Group include selected and dump sample results from 1942 and 1943. The file reports a selected sample from the upper location hole on Tactite Claim No. 1 at 14.40% WO3, two additional 1942 samples reporting 0.8% WO3 and 0.9% WO3, and a 1943 University of Nevada State Analytical Mining Laboratory report describing metamorphosed rock with garnet and traces of scheelite reporting tungsten trioxide of 0.35%.6

Historical production-related references are limited but relevant for exploration context. The War Bond Mine MRDS-derived record lists production for 1953, a time period of 1952 to 1953, and a reported grade description of approximately 0.3% to 0.45% WO3. The Tactite Thursday MRDS-derived record further states that a 250-ton test lot of material averaging 0.3% WO3 was mined from the Old Discovery East Pit.7

Based on these historical records, the project represents a historically explored tungsten skarn system with documented scheelite-bearing tactite mineralization, historical surface workings, historical sampling and limited historical mining or test-lot production.

Historical Information and Exploration Context

The mineral properties comprising the Company’s portfolio have been the subject of extensive historical exploration, development work, and, in several cases, past production. The historical exploration results, sampling, drilling and other technical information referenced herein were completed prior to the adoption of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and do not comply with current NI 43-101 requirements. As a result, such historical information should not be relied upon. While this historical information is non-compliant, it is considered highly relevant for exploration targeting, geological interpretation, and the design of modern exploration and evaluation programs.

Management believes that the existence of extensive historical work and past production creates a compelling foundation for modern exploration, particularly when reassessed using contemporary geological models, exploration technologies, metallurgical processes, and prevailing commodity prices. However, readers are cautioned that historical results, resources, or economic conclusions cannot be verified or confirmed at this time.

In order to define current mineral resources, assess metallurgy, and evaluate economic viability, the Company will be required to complete confirmation drilling, modern metallurgical studies, updated technical evaluations, and NI 43-101 compliant mineral resource estimates and feasibility or economic studies. There is no assurance that historical results will be confirmed or that any project will advance to economic viability.
