Vault Strategic Mining Corp. Advancing War Bond Tungsten Project with High-Resolution UAV Magnetic Survey

VANCOUVER, British Columbia — July 10, 2026 — Leads & Copy — Vault Strategic Mining Corp. (TSXV: KNOX) (OTC: KNXFF) (FSE: M850) (WKN: A41WE4) is advancing plans for a high-resolution UAV-based airborne magnetic survey at its War Bond Tungsten Project in Nevada, USA. The project encompasses the Historical War Bond Tungsten Mine, Historical Tactite Tungsten Mine, and Historical Thursday Tungsten Mine.

Nevada was recognized as the top mining jurisdiction globally in the Fraser Institute’s Annual Survey of Mining Companies released on February 26, 2026.

The proposed Drone-Mag survey, expected to be executed by Pioneer Exploration Consultants Ltd., a specialist in UAV-based geophysical surveying, will involve approximately 70 line-kilometres of airborne magnetic data collection. The survey will utilize tightly spaced 25-metre flight lines and 250-metre perpendicular tie lines to ensure high-density geophysical coverage over the target area.

Vault intends to leverage the survey results to refine its geological interpretation, identify structural trends, and delineate magnetic features potentially associated with tungsten-bearing systems and historical mine workings. This geophysical program is considered a significant next step in transitioning from historical mine-scale observations and surface exploration towards a more systematic drill targeting model.

"War Bond represents a compelling historical tungsten project in one of the world’s top mining jurisdictions, and our objective is to move aggressively but methodically toward drill-ready targets," stated Quinn Field-Dyte, Chief Executive Officer of Vault Strategic Mining Corp. "This planned Drone-Mag survey is designed to give us a higher-resolution subsurface dataset that can be integrated with mapping, sampling, historical workings and structural interpretation. The goal is clear: delineate priority targets and build a disciplined drill program."

The survey will employ a UAV-based magnetic system featuring a Blacksquare Hercules drone platform, a GEM Systems GSMP-35U potassium vapour magnetometer, and GEM Systems GSM-19 Overhauser base stations. The methodology is designed for high-quality magnetic data collection while maintaining safe, efficient, terrain-following flight operations.

Publicly available LiDAR data will be used to generate a digital elevation model and digital surface model, supporting accurate terrain following and obstacle avoidance. Anticipated deliverables include a survey logistics report, total field map, first vertical derivative map, analytical signal map, and a processed, micro-levelled magnetic database.

The Company expects the Drone-Mag data to be evaluated alongside current and historical exploration information to define targets for follow-up work, which may include ground truthing, mapping, sampling, and drill planning. Vault cautions that geophysical anomalies are not necessarily indicative of mineralization, and all targets will require follow-up exploration and geological verification.

The War Bond claim package comprises 20 unpatented lode mining claims, covering approximately 400 acres 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.

Historical records suggest that War Bond, Tactite, Thursday, Old Discovery, and Knight Claims are related or overlapping property names within the same broader tungsten occurrence area. The War Bond Mine MRDS-derived record identifies War Bond Mine as a tungsten mine in Douglas County, Nevada, listing Tactite and Thursday, Old Discovery, and Knight Claims as secondary names.

Another MRDS-derived record for the War Bond Tungsten Mine lists Tactite & Thursday, Old Discovery Claim, Knight Claims, Tungsten Valley Claim, Yellow Problem Claim, and Margret Claim as related secondary names. Carson Tungsten Co. was listed as the owner, with information dating back to 1952, and the operation category was noted 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, stating that scheelite occurs in a small tactite area near a granite-limestone contact.

The MRDS-derived Tactite Thursday record describes the occurrence as a W skarn with scheelite as the mineral and epidote, garnet, quartz, and calcite as gangue minerals. This record also reports two principal mineralized areas: 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.

Historical assay and laboratory records from 1942 and 1943 include selected and dump sample results. One report details a selected sample from the upper location hole on Tactite Claim No. 1 at 14.40% WO3, with two additional 1942 samples reporting 0.8% WO3 and 0.9% WO3. A 1943 University of Nevada State Analytical Mining Laboratory report described metamorphosed rock with garnet and traces of scheelite, reporting tungsten trioxide of 0.35%.

Historical production references, though limited, are relevant for exploration context. The War Bond Mine MRDS-derived record lists production for 1953, with a period of 1952 to 1953 and a reported grade description of approximately 0.3% to 0.45% WO3. The Tactite Thursday MRDS-derived record states that a 250-ton test lot of material averaging 0.3% 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.

The mineral properties have been subject to extensive historical exploration, development work, and, in several cases, past production. However, these historical exploration results, sampling, and technical information were completed prior to National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and do not comply with current NI 43-101 requirements. Therefore, this historical information should not be relied upon, though it is considered relevant for exploration targeting, geological interpretation, and the design of modern exploration and evaluation programs.

Management believes that the extensive historical work and past production provide a 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. To define current mineral resources, assess metallurgy, and evaluate economic viability, the Company will need 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.

Vault Strategic Mining Corp. is a North American resource company focused on acquiring and advancing strategic and critical mineral projects in top-tier mining jurisdictions. The Company prioritizes historical and underexplored assets with potential for value creation through modern exploration and disciplined development.
