Excalibur Engages Precision GeoSurveys for Airborne Geophysical Survey at Bellehelen

(TSXV: EXCL) (OTCQB: EXCBF) Excalibur Metals Corp. has engaged Precision GeoSurveys US Inc. to conduct a high-resolution helicopter-borne magnetic and radiometric survey at the Bellehelen Silver-Gold Project in Nye County, Nevada. The planned survey will cover approximately 876 line-kilometres over 79.6 square kilometres, with 100-metre survey-line spacing, 1,000-metre tie-line spacing, and a nominal terrain clearance of 30 metres. In areas overlapping with the 2020 survey, new lines will be offset by 50 metres, providing effective 50-metre spacing. The program consists of approximately 795 line-kilometres of survey lines and 81 line-kilometres of perpendicular tie lines. Precision will use the same reference point, technologies, and specifications as the 2020 survey to facilitate merging datasets. Magnetic measurements will be collected at 20 samples per second, providing one- to two-metre sample intervals, while radiometric measurements will be collected once per second. Mobilization is anticipated in mid-November 2026, subject to operational considerations, with final processed data and maps expected three to four weeks after field operations are completed. Precision GeoSurveys has completed more than 800 airborne geophysical surveys since 2007, including the 2020 Bellehelen survey. Precision's President, Harmen J. Keyser, P.Geo., is a geologist and helicopter pilot with over 40 years of experience and more than 12,000 hours of flight time. Bellehelen encompasses a 10-kilometre-long mineralized trend that historically produced an estimated 311,000 silver-equivalent ounces in the early 1900s. Historical surface sampling returned high-grade assays of up to 11.25 g/t gold and 3,490 g/t silver. Excalibur Metals Corp. has acquired the option to purchase 100% of the Bellehelen Project. Numerous historic workings are distributed along the corridor, and recent drilling and geophysical programs demonstrate potential for both higher-grade and disseminated mineralization. John Gilbert is CEO of Excalibur Metals Corp. Matthew Dumala, P.Eng., an independent consultant, is the Qualified Person who reviewed and approved the technical information in the release.

Excalibur Metals Plans Property-Wide Exploration Program at Bellehelen Silver-Gold Project and Announces Director Nominees

(TSXV: EXCL) (OTCQB: EXCBF) Excalibur Metals Corp. announced plans for an extensive follow-up field exploration program at its Bellehelen Silver-Gold Project in Nye County, Nevada. The planned Program will include detailed geological mapping and systematic rock-chip sampling across a broad portion of the Project. The Company's maiden drill program at Spyglass Ridge consisted of 3,122 metres of reverse-circulation drilling across ten holes. The drill program identified multiple zones of gold-silver mineralization, including 360.0 grams per tonne silver and 2.03 grams per tonne gold over 1.52 metres within a broader interval of 16.7 grams per tonne silver and 0.10 grams per tonne gold over 100.58 metres in drill hole BH26001. Bellehelen encompasses a district-scale, approximately 10-kilometre-long mineralized trend marked by numerous historic workings, extensive vein networks and widespread gold-silver mineralization. Bellehelen historically produced an estimated 311,000 silver-equivalent ounces in the early 1900s. Historical surface sampling returned high-grade assays of up to 11.25 grams per tonne gold and 3,490 grams per tonne silver.

Excalibur Metals Defines New Silver-Gold Soil Anomalies North of Spyglass Ridge

(TSXV: EXCL) (OTCQB: EXCBF) Excalibur Metals Corp. announced results from expanded soil sampling north of the Spyglass Ridge Target at its Bellehelen Silver-Gold Project in Nye County, Nevada. The results have outlined multiple silver-gold soil anomalies across an approximately one-kilometre-long corridor extending north from Spyglass Ridge, including the newly defined Zigs Target and the extended Broken Cabin Target. Soil sampling at Zigs identified gold values of up to 449 parts per billion and silver values of up to 2.0 parts per million, with multiple samples returning more than 100 ppb gold across a target area measuring approximately 300 m by 300 m. At Broken Cabin, the expanded dataset returned gold values of up to 331 ppb and silver values of up to 7.8 ppm, outlining a broad target area measuring approximately 300 m by 600 m. Bellehelen encompasses a district-scale, 10-kilometre-long mineralized trend that historically produced an estimated 311,000 silver-equivalent ounces in the early 1900s. Historical surface sampling returned high-grade assays of up to 11.25 g/t gold and 3,490 g/t silver. Excalibur Metals Corp. has acquired the option to purchase 100% of the Bellehelen Project in Nye County, Central Nevada.

Excalibur Provides Exploration Update on Rangefront Target

(TSXV: EXCL) (OTCQB: EXCBF) Excalibur Metals Corp. announced an exploration update on the Rangefront Target at the Bellehelen Silver-Gold Project in Nye County, Nevada. In March 2026, the company collected 264 soil samples in a grid covering the Rangefront Target, with results showing a strong, coherent anomaly in antimony, arsenic, mercury, and gold concentrated immediately along the rangefront. A CSAMT geophysical survey completed in April 2026 by KLM Geoscience identified a prominent west-dipping structural feature interpreted as a fault zone, which may represent an important control on hydrothermal fluid flow and mineralization. Bellehelen encompasses a district-scale, 10-kilometre-long mineralized trend that historically produced an estimated 311,000 silver-equivalent ounces in the early 1900s, with historical surface sampling returning high-grade assays of up to 11.25 g/t gold and 3,490 g/t silver. Excalibur has acquired the option to purchase 100% of the Bellehelen Project in Nye County, Central Nevada. The next drill campaign at Rangefront and Spyglass Ridge is anticipated in late 2026 or early 2027. The company projects continued exploration at Bellehelen through additional geological mapping, surface sampling, geophysical surveys, and integrated interpretation of recent drilling results over the remainder of 2026.

Excalibur Releases Remainder of Drilling Results from Spyglass

(TSXV: EXCL) (OTCQB: EXCBF) Excalibur Metals Corp. announced drill results from the final four holes of its 3,122-metre drill program at the Spyglass Ridge Target, part of the Bellehelen Silver-Gold Project in Nye County, Nevada.
