NEWS RELEASE

Excalibur Metals Commences Property-Wide Exploration Program at Bellehelen

September 15th, 2026 (TSXV:EXCL)( OTCQB: EXCBF)

VANCOUVER, BRITISH COLUMBIA, Excalibur Metals Corp. (TSXV:EXCL) (OTCQB:EXCBF) (“Excalibur” or the

“Company”) is pleased to announce that field crews have commenced the Company’s previously announced

exploration program (the “Program”) at its Bellehelen Silver- Gold Project (“Bellehelen” or the “Project”) in

Nye County, Nevada.

The Program is focused on advancing priority targets and evaluating the broader mineralized corridor across

Bellehelen. Initial work includes:

• A ground gravity survey now underway at the Rangefront Target (“Rangefront”);

• Extensive geological and structural mapping across the multi-kilometre corridor between Rangefront

and the Spyglass Ridge Target (“Spyglass Ridge”); and

• Systematic rock -chip sampling of prospective structures, alteration zones and historic workings

throughout the corridor.

At Rangefront, located approximately eight kilometres northwest of Spyglass Ridge, previous soil sampling and

CSAMT geophysics identified a large target that extends beneath shallow cover to the west. The gravity survey

is intended to help the Company better define the geology and key structures beneath the cover and further

refine targets for future drilling.

Field crews are also undertaking extensive mapping and rock-chip sampling across the largely underexplored

area between Rangefront and Spyglass Ridge. This work is intended to identify prospective structures,

alteration and mineralization that may connect or expand upon the Company’s existing targets and to develop

additional targets for follow-up exploration and potential drilling.

“This program represents an important step at Bellehelen, which remains a largely untested, district -scale

mineralized system,” commented John Gilbert, CEO of Excalibur. “We’re building on our success at Spyglass

while continuing to evaluate the broader po tential of the Project. There are very few large precious -metal

systems in Nevada that have seen such limited modern exploration , particularly those controlled by a junior

exploration company. We believe the scale and upside potential at Bellehelen are considerable.”

“The gravity survey will add another layer of information to our understanding of the concealed target at

Rangefront, while extensive mapping and sampling between Rangefront and Spyglass Ridge will allow us to

systematically evaluate a multi-kilometre area that has seen very limited previous exploration. Each phase of

fieldwork continues to generate new priority targets and reinforce our view of Bellehelen’s potential.”

Results from the Program will be integrated with the Company’s existing geological, geochemical, geophysical

and drilling datasets to refine and prioritize targets across Bellehelen ahead of future drilling.

About Bellehelen

Bellehelen encompasses a district -scale, 10-kilometre-long mineralized trend that historically produced an

estimated 311,000 silver-equivalent ounces in the early 1900s 1. Numerous historic workings are distributed

along the entire length of this extensive corridor, highlighting a continuity of mineralization across multiple

zones on the Property. Historical surface sampling returned high -grade assays of up to 11.25 g/t go ld and

3,490 g/t silver1, confirming the presence of a fertile precious metal system. Broad soil anomalies, extensive

vein networks and the results of the Company’s recent drilling and geophysical programs demonstrate the

potential for both structurally controlled higher- grade mineralization and broader zones of disseminated

mineralization.

About Excalibur Metals Corp.

Excalibur Metals Corp. is focused on exploring for precious metals within established mining areas in the

Western United States. The Company has acquired the option to purchase 100% of the Bellehelen Project in

Nye County, Central Nevada. The claims cover most of the historic Bellehelen Mining District, where gold and

silver were initially discovered and mined in the early 1900s. Excalibur has assembled an exceptional team

with considerable exploration, developing and permitting experience within North America. Excalibur is traded

on the TSX Venture Exchange (TSXV) under the symbol “EXCL” and on the OTCQB Venture Market under the
