VAULT STRATEGIC PLANS DRONE-MAG SURVEY TO ADVANCE DRILL TARGET DELINEATION AT THE WAR BOND TUNGSTEN PROJECT IN NEVADA

Vault Strategic Mining Corp. is advancing plans for a high-resolution unmanned-aerial-vehicle-based airborne magnetic survey at its War Bond tungsten project, which includes the historical War Bond tungsten mine, historical Tactite tungsten mine and 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.

The proposed drone-mag survey is expected to be completed by Pioneer Exploration Consultants Ltd., a specialist in UAV-based geophysical surveying. The survey plan contemplates approximately 70 line kilometres of airborne magnetic data collection using tightly spaced 25-metre flight lines and 250-metre perpendicular tie lines, providing high-density geophysical coverage over the target area.

Vault intends to use the survey results to refine its geological interpretation, identify structural trends and delineate magnetic features that may be associated with tungsten-bearing systems and historical mine workings. The company believes the planned geophysical program represents an important next step in moving from historical mine-scale observations and surface exploration toward 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. "This planned drone-mag survey is designed to give us a higher-resolution subsurface data set 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 proposed survey will utilize a UAV-based magnetic system consisting of a Blacksquare Hercules drone platform, a GEM Systems GSMP-35U potassium vapour magnetometer and GEM Systems GSM-19 Overhauser base stations. The survey methodology is designed to collect high-quality magnetic data while maintaining safe, efficient, terrain-following flight operations over the survey area.

Publicly available lidar data are expected to be used to generate a digital elevation model and digital surface model to support accurate terrain following and obstacle avoidance during the survey. Upon completion, anticipated deliverables include a survey logistics report, total field map, first vertical derivative map, analytical signal map and a processed, microlevelled 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. The company cautions that geophysical anomalies are not necessarily indicative of mineralization, and all targets will require follow-up exploration and geological verification.

Historical War Bond tungsten mine

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 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 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 the War Bond mine as a tungsten mine in Douglas county, Nevada, and lists Tactite and Thursday, Old Discovery, and Knight claims as secondary names.

A separate MRDS-derived War Bond tungsten mine record identifies Tactite and 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.

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, 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 western 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 per cent WO3 and an east 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 tungsten trioxide of 0.35 per cent.

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

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 and other technical information referenced herein were completed prior to the adoption of National Instrument 43-101 (Standards of Disclosure for Mineral Projects) 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.

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.
