VAULT ENGAGES AMAZONA FOR MAIDEN EXPLORATION
PROGRAM AT MT. WHEELER TUNGSTEN PROJECT, NEVADA
Vancouver, British Columbia - April 2, 202 6 – Vault Strategic Mining Corp . (TSXV:KNOX)
(OTC:KNXFF) (FSE:M850) ("VAULT" or the "Company") is pleased to announce that it has engaged
veteran geologist William “Bill” Feyerabend, CPG and Amazona Enterprises (“Amazona”) for a planned
field exploration and reconnaissance program at the Company’s Mt. Wheeler Historical Tungsten Mine
(“Wheeler”), a historical Tungsten project in Nevada, USA.

Quinn Field-Dyte, Chief executive officer, commented: “We are pleased to have the opportunity to
collaborate with Mr. Feyerabend and the team at Amazona. Following the recent acquisition, we are
excited to commence our initial exploration activities at the Mt. Wheeler Tungsten Historical Mine without
delay. This program represents an important first step toward the preparation of an NI 43 -101 technical

report, aimed at evaluating and advancing the potential of Mt. Wheeler in Nevada —a state consistently
ranked among the world’s premier mining jurisdictions by the Fraser Institute.”
The reconnaissance program is anticipated to involve a short -duration field assessment carried out by a
small, specialized team using appropriate equipment. The planned work will focus on addressing key
geological questions, including host rock characteris tics, structural controls, and mineralizing processes
relevant to tungsten systems. The results are expected to support the Company in refining its exploration
strategy for this critical minerals–focused asset.
The Company also intends to continue its engagement with Amazona in the preparation of an NI 43 -101
Technical Report and comprehensive technical overview of the Mt. Wheeler Tungsten Historical Mine.
This effort is expected to incorporate a review of available historical data, regional and property -scale
geological context, and findings from the planned field program, with a focus on assessing the project’s
potential role with in the North American critical minerals supply chain, particularly with respect to
tungsten.

In addition, the Company is evaluating potential future submissions to relevant U.S. federal and state
agencies in connection with programs supporting critical minerals development. These initiatives may
include studies related to historical mine infrastructure, current site conditions, and the potential
rehabilitation of the Mt. Wheeler Tungsten Hist orical Mine, subject to further technical evaluation,
regulatory approvals, and funding considerations.
About Mount Wheeler Historical Tungsten Mine – Nevada, USA
The main period of activity began with the discovery of tungsten in 1950. Between 1952 and 1955, Mt.
Wheeler Mines, Inc., under a Defence Minerals Exploration Administration (“DMEA”) contract. Between
1952 and 1954, 1,800 tons of rock averaging 1.3% WO3 was extracted and milled at Minerva, Nevada,
3
with 75% DMEA sponsorship2. The average grade of all rock mined from the Pole Adit zone is about 0.5%
WO3 as shown by the production figures.3
A feasibility study titled “Feasibility Study Mt. Wheeler Mine Beryllium project” was commissioned in
1972 by W.S. Moore Co. which states that “Milling was successfully piloted by the C olorado School of
Mines”4 “From 1959 to 1962, largely through the efforts of the Anaconda Company, an additional 4,475
feet of laterals and sub drifts were driven. Approximately 1,000 samples were taken.” 5 An indicated
Tungsten-Beryllium resource was prepared.
The access roads to the mine are all blacktopped except for the last five-mile stretch which is gravel.
Historical Information and Exploration Context
The Wheeler Tungsten Historical Mine Project been the subject of extensive historical exploration,
development work, and, in several cases, past commercial production or advanced -stage evaluations with
the intent to commence mining. The historical exploration results, sampling, drilling, resource es timates,
feasibility studies, 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 and any historical
resource estimates should not be relied upon as current mineral resources or reserves.
In particular, the Mount Wheeler Tungsten -Beryllium Project is supported by historical feasibility -level
study and substantial historical underground exploration; however, these studies were completed under
historical standards and assumptions and are considered non -compliant under NI 43 -101. All projects
within the portfolio have a documented history of either mining, advanced development, or demonstrated
intent to advance toward production, which provides valuable geological context and technical insight.
The Company has been provided with a compilation of historical technical data, including non-NI 43-101
compliant resource estimates, drilling records, sampling results, mine plans, metallurgical representations,
and feasibility-level evaluations. 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, past production, and prior feasibility-
level evaluations creates a compelling foundation for modern exploration, particularly when reassessed
using contemporary geological models, explora tion 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 est imates and feasibility or economic
studies. There is no assurance that historical results will be confirmed or that any project will advance to
economic viability.
