VAULT STRATEGIC ENGAGES AMAZONA FOR MAIDEN NI 43-101 TECHNICAL REPORT ON HISTORICAL TUNGSTEN MINE PORTFOLIO AT WAR BOND, NEVADA

Vault Strategic Mining Corp. has engaged veteran geologist William (Bill) Feyerabend, CPG, and Amazona Enterprises for a maiden National Instrument 43-101 technical report at the company's War Bond tungsten project, which includes the historical War Bond tungsten mine, the historical Tactite tungsten mine and the Historical Thursday tungsten mine, located in Nevada, United States.

Nevada was ranked as the No. 1 mining jurisdiction in the Fraser Institute's Annual Survey of Mining Companies released on Feb. 26, 2026.

Quinn Field-Dyte, chief executive officer of Vault Strategic Mining, stated: "We are excited to have engaged Amazona Enterprises and veteran geologist William (Bill) Feyerabend to prepare the maiden NI 43-101 technical report for the War Bond tungsten project. This report represents an important step in consolidating our recent and planned exploration results, strengthening our understanding of the project and establishing recommendations for its next phase of advancement. As the United States and its allies prioritize secure domestic supplies of critical minerals, we believe tungsten's essential role in defence, aerospace and advanced manufacturing underscores the strategic importance of War Bond. We are enthusiastic about advancing this historically productive tungsten project in Nevada, one of the world's top-ranked mining jurisdictions."

Amazona will integrate the results from the recently completed phase 1 exploration program with data generated through the planned phase 2 program, including the recently announced drone-flown airborne magnetic survey. The combined geological, geochemical and geophysical data sets will support the preparation of an independent NI 43-101 technical report for the War Bond tungsten project. The report is expected to provide an updated technical evaluation of the historical tungsten mine portfolio, including recommendations for the next phase of exploration and advancement, including potential target refinement, additional fieldwork and future drilling.

Strategic importance of Nevada War Bond tungsten project amid escalating global supply chain risks

The company further highlights the growing strategic importance of its War Bond tungsten project in Nevada amid escalating geopolitical tensions, concerns surrounding global shipping routes and continued restrictions on critical mineral exports. As the United States, Canada and allied nations work to strengthen secure domestic supply chains, tungsten has emerged as an essential defence and industrial metal due to its exceptional hardness, density and heat resistance. Tungsten is classified as a critical mineral by both the United States and Canada and is used in:

• Armour-piercing ammunition and kinetic energy penetrators;
• Missile guidance and weapons systems;
• Aerospace and aviation components;
• High-performance cutting and machining tools;
• Semiconductor manufacturing equipment;
• Energy infrastructure and advanced industrial technologies.

Located within one of Nevada's prolific mineral belts, the War Bond project includes the historical War Bond, Tactite and Thursday tungsten mines, each of which produced tungsten during previous periods of heightened demand. Vault is applying modern exploration techniques to evaluate the district, expand known mineralization and identify additional opportunities within the historically productive tungsten camp. With global demand supported by rising defence spending, infrastructure investment, electrification, advanced manufacturing and artificial-intelligence-related industrial expansion, the company believes War Bond is well positioned to benefit from the long-term shift toward secure North American tungsten production.

Historical War Bond tungsten mine

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

The War Bond tungsten project includes the historical War Bond, Tactite and Thursday tungsten mine areas in western Nevada. Available on-line historical records appear to treat the 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 (Mineral Resources Data System) War Bond mine record identifies the War Bond mine as a tungsten mine in Douglas county, Nevada, and lists the Tactite & Thursday, Old Discovery and Knight claims as secondary names.

A separate MRDS-derived War Bond tungsten mine record identifies Tactite & Thursday, the Old Discovery claim, the Knight claims, the Tungsten Valley claim, the Yellow Problem claim and the 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.

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.

The MRDS-derived Tactite & Thursday record describes the occurrence as a tungsten skarn with scheelite as mineral and epidote, garnet, quartz and calcite as gangue minerals. The same record reports two principal mineralized areas, including a western zone with scheelite in narrow widths up to 0.3 per cent WO3 (tungsten trioxide) and an eastern zone where scheelite is reported in small shoots with values ranging from 0.25 per cent to 0.45 per cent WO3 over widths of four to eight feet.

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 per cent WO3, two additional 1942 samples reporting 0.8 per cent WO3 and 0.9 per cent WO3, and a 1943 University of Nevada State Analytical Mining Laboratory report describing metamorphosed rock with garnet and traces of scheelite reporting 0.35 per cent WO3.

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 per cent to 0.45 per cent WO3. The Tactite & Thursday MRDS-derived record further states that a 250-ton test lot of material averaging 0.3 per cent WO3 was mined from the Old Discovery East pit.

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
