Excalibur Metals Corp. (TSX-V: EXCL) (OTCQB: EXCBF) is pleased to announce drill results from the final four holes of its 3,122-metre drill program at the Spyglass Ridge Target, located at the Company’s Bellehelen Silver-Gold Project, Nye County, Nevada. For gold and silver results from the first six holes of the program , see the Company’s news release dated June 3, 2026.

Highlights

• Encouraging results from the final four drillholes at Spyglass Ridge including an intercept in BH26008 of 3.05 meters grading 0.20 grams per tonne gold and 21.8 g/t silver and an intercept in BH26010 of 1.52 m grading 0.48 g/t Au and 29.1 g/t Ag
• Rangefront is slated as a priority target for the Company’s next drill campaign, along with follow-up drilling at Spyglass Ridge, anticipated in late 2026 or early 2027
• In the coming months, the Company will remain focused on identifying, advancing, and prioritizing targets at Bellehelen to optimize the chances of discovery during subsequent drilling

Multiple zones of anomalous gold and silver mineralization were identified in holes BH26008 and BH26010, including an intercept in BH26008 of 3.05 m grading 0.20 g/t Au and 21.8 g/t Ag and an intercept in BH26010 of 1.52 m grading 0.48 g/t Au and 29.1 g/t Ag. The occurrence of multiple coincident gold-silver intercepts across separate drill holes confirms the presence of a mineralized structure running parallel to Spyglass Ridge that continues to a depth of at least 300 metres. Particularly encouraging is the continuity of elevated gold and silver values over tens of metres in both BH26008 and BH26010, suggesting the potential for disseminated mineralization on the Project. Holes BH26007 and BH26009 primarily returned gold and silver values below detection limit.

In the Company’s next drill campaign, follow-up drilling is planned with the aim of identifying high-grade shoots along the mineralized structure at Spyglass Ridge in addition to testing other targets.

John Gilbert, CEO of Excalibur Metals, commented: “These results continue to demonstrate the scale and fertility of the Bellehelen hydrothermal system. We’re encouraged by the early-stage results at Spyglass Ridge, where the presence of multiple gold-silver intercepts in separate drill holes provides further evidence that we are vectoring toward a robust mineralized system. We’ll continue to advance the Project on multiple fronts by undertaking systematic exploration in the lead-up to our next round of drilling.”

Next Steps

Over the summer and fall of 2026, the Company plans to conduct additional mapping and sampling, collect further geophysical data, and model the results of its recent drilling to identify, define, and rank future drill targets at Bellehelen, including, but not limited to Spyglass Ridge. The objective of this work is to refine and prioritize drill targets ahead of the Company’s next planned drill campaign. The Company is encouraged by the results of its maiden drill program, which confirm the scale and potential of the Bellehelen system, and remains focused on identifying the principal mineralizing structures along the eight-kilometre trend.

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 1900s¹. 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 gold and 3,490 g/t silver1, confirming the presence of a fertile precious metal system. In addition, broad soil anomalies and extensive vein networks within the large structural corridor suggest the potential for both high-grade shoots and bulk-tonnage targets, underscoring the exceptional scale and prospectivity of the Bellehelen Property.

As it relates to adjacent properties disclosed in this news release, such as Round Mountain and Arthur, such mineralization is not necessarily indicative to the mineralization on the Project.
