Loyalist updates mineral resource at Tully: 1.62 Mt indicated at 3.16 g/t Au, 0.95 Mt inferred at 2.03 g/t Au

  Updated Geological Model Defines a Larger, Higher-Confidence Underground Gold System with Significant Exploration Upside and a Strong Foundation for Future Development   Toronto, Ontario – TheNewswire - July 7, 2026 – Loyalist Exploration Limited ("Loyalist" or the "Company") (CSE: PNGC) is pleased to announce significantly updated independent Mineral Resource Estimates (" MRE ") for its 100%-owned Tully Gold Project (" Tully " or the " Project "), located in the prolific Timmins Gold Camp of northeastern Ontario. Prepared by P&E Mining Consultants Inc. ("P&E") in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") and the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014), the 2026 MRE substantially increases geological confidence while defining a larger, more continuous underground gold system that strengthens the Project's pathway toward future engineering and economic studies. The updated geological interpretation also confirms that mineralization remains open along strike and at depth, highlighting significant potential for future expansion through additional drilling.

The effective date of the Mineral Resource Estimate is June 15, 2026.     Figure 1: 73% of the contained gold ounces classified as Indicated Mineral Resources, representing approximately 15% of the known mafic tuff host unit volume. Key Highlights Indicated Mineral Resource Estimate: 1.62 million tonnes grading 3.16 g/t gold, containing 164,000 ounces of gold, representing approximately 73% of total contained gold ounces, that makes up approximately 15% of the known tuff unit volume.   Inferred Mineral Resource Estimate: 0.95 million tonnes grading 2.03 g/
