Eureka Metals Mobilizes 2026 Exploration Program at Tyee Titanium Project to Advance High-Grade Titanium Targets and Evaluate Untested EM Anomalies

About this update from Eureka Metals Corp.

Vancouver, British Columbia--(Newsfile Corp. - June 3, 2026) - Eureka Metals Corp. (CSE: ERKA) (OTCQB: UREKF) (FSE: S58) ("Eureka" or the "Company") is pleased to announce the mobilization of its Phase 1 summer prospecting program at the Company's 100%-owned Tyee Titanium Project (the "Project") located near Havre-Saint-Pierre, Québec. Highlights "With multiple high-grade titanium targets, strong geophysical signatures, and several untested EM anomalies identified across the Project, we believe Tyee represents one of the more compelling emerging titanium exploration stories in Québec," stated Danny Matthews, CEO. "This program is designed to rapidly advance several priority target areas while continuing to unlock the broader exploration potential of the district." Phase 1 Prospecting Program The program is being managed by IOS Geosciences and represents the first phase of Eureka's planned 2026 exploration campaign at Tyee. A four-person field crew mobilized to Havre-Saint-Pierre on May 28, 2026, with helicopter-supported prospecting operations expected to continue through June 17, 2026. The Phase 1 program will focus on a combination of newly identified EM anomalies and several of the Company's highest-priority historical target areas, including Big Tio, NS Trend, and East Nugget. These targets were identified through previous prospecting, geophysical surveying, and sampling campaigns completed across the Project and are associated with strong conductive and magnetic signatures interpreted to reflect extensive titanium-vanadium-scandium mineralization. Historical Target Areas Historical surface sampling at Big Tio returned average grades of 36.07% TiO2 from 12 grab samples, while the NS Trend target returned average grades of 31.89% TiO2 across 15 grab samples and an interpreted strike length of approximately 2.3 kilometres. East Nugget returned average grades of 34.50% TiO2 across 3 grab samples. The Company believes these targets highlight the scale potential and high-grade nature of titanium mineralization across the Tyee district and warrant systematic follow-up exploration. Figure 1.
