VAULT STRATEGIC ANNOUNCES MAGNETIC SURVEY RESULTS TO SUPPORT MAIDEN NI 43-101 TECHNICAL REPORT, FOLLOW-UP EXPLORATION AND DRILL PERMITTING AT WAR BOND TUNGSTEN PROJECT, NEVADA

Vault Strategic Mining Corp. has released the results from its high-resolution unmanned aerial vehicle (UAV) magnetic survey and received the associated logistics report and maps for its War Bond tungsten project in Nevada, United States. The War Bond project encompasses the historical War Bond, Tactite and Thursday tungsten mines

The survey provides an additional technical data set intended to support the preparation and filing of the company's previously announced maiden National Instrument 43-101 technical report, guide follow-up surface exploration and inform the planning of future drill permit applications.

Completed by Pioneer Exploration Consultants Ltd. on Aug. 3, 2026, the survey comprised approximately 73.6 line kilometres, with closely spaced 25-metre survey lines and 250-metre tie lines. The survey package includes processed total magnetic intensity, first vertical derivative and analytic signal maps, providing complementary tools for evaluating variations in magnetic response across the surveyed area.

Quinn Field-Dyte, chief executive officer of Vault, commented: "We are thrilled to have the results of the high-resolution magnetic survey, an important step in advancing War Bond. We now have an additional data set to integrate with our surface exploration results and historical geological information as we work toward filing the project's maiden NI [National Instrument] 43-101 technical report. We are excited to use this information to guide follow-up surface exploration, refine potential drill targets and support the preparation of drill permit applications. Each phase of work builds our understanding of War Bond and helps us plan the next stage of exploration with greater confidence."

Supporting the maiden technical report and exploration planning

The company intends to integrate the magnetic survey data with available geological mapping, historical information and results from its completed surface exploration program. Subject to review and interpretation by the project's qualified person, this combined information is expected to strengthen the technical foundation for the maiden NI 43-101 technical report and assist in developing recommendations for subsequent exploration.

Magnetic surveys can help evaluate geological contacts and structural features where differences in magnetic properties exist. At War Bond, interpretation of the new data set alongside geological and geochemical information is intended to help prioritize areas for follow-up mapping and sampling, assess potential exploration targets, and inform the selection of possible drill sites.

This work is also intended to support the preparation of future drill permit applications by helping refine proposed exploration locations and the scope of planned activities. Any drilling will remain subject to technical evaluation, receipt of applicable permits, financing and access requirements.

The completion of the survey represents a further step in Vault's systematic evaluation of War Bond, providing a detailed geophysical framework to guide the next phase of fieldwork and technical assessment.

Technical context

Pioneer's report documents survey acquisition, processing, quality control and map products; it does not include geological interpretation of the data set. Magnetic responses alone do not establish the presence, grade or continuity of tungsten mineralization. Further interpretation and field verification are required before their exploration significance can be assessed.

War Bond tungsten project: historical context

The War Bond claim package comprises 20 unpatented lode mining claims covering approximately 400 acres in the Delaware mining district of western Nevada. The property encompasses the historical War Bond mine and the Tactite and Thursday tungsten workings.

Available on-line historical records appear to use War Bond, Tactite, Thursday, Old Discovery and Knight Claims as related or overlapping names within a broader tungsten occurrence rather than as distinct modern locations. Western Mining History's MRDS-derived War Bond mine record identifies War Bond 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 lists Tactite and Thursday, Old Discovery Claim, Knight Claims, Tungsten Valley Claim, Yellow Problem Claim, and Margret Claim as related secondary names. The record also identifies Carson Tungsten Co. as the owner, provides an information year of 1952 and classifies the operation as a past producer. Historical descriptions associate tungsten mineralization in the area 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 being located approximately 15 miles southeast of Carson City in Section 9, T. 14 N., R. 21 E., and reports scheelite in a small tactite area near a granite-limestone contact.

The MRDS-derived Tactite and Thursday record describes the occurrence as a tungsten skarn with scheelite mineralization and epidote, garnet, quartz and calcite gangue. The record identifies two principal mineralized areas: a west zone with narrow scheelite-bearing widths reporting up to 0.3 per cent WO3 (tungsten trioxide) and an east zone with small scheelite shoots reporting values of 0.25 per cent to 0.45 per cent WO3 over widths of four to eight feet.

Historical assay and laboratory records contained 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. Reported results include a selected sample from the upper location hole on Tactite claim No. 1 grading 14.40 per cent WO3, two additional 1942 samples grading 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 grading 0.35 per cent WO3.

Historical production references are limited but provide relevant exploration context. The MRDS-derived War Bond mine record lists production in 1953, a production period from 1952 to 1953 and a reported grade range of approximately 0.3 per cent to 0.45 per cent WO3. The Tactite Thursday record also states that a 250-ton test lot averaging 0.3 per cent WO3 was mined from the Old Discovery East pit.

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

Historical information and exploration context
