EUREKA METALS MOBILIZES 2026 EXPLORATION PROGRAM AT TYEE TITANIUM PROJECT TO ADVANCE HIGH-GRADE TITANIUM TARGETS AND EVALUATE UNTESTED EM ANOMALIES

Eureka Metals Corp. is preparing for its phase 1 summer prospecting program at the company's 100-per-cent-owned Tyee titanium project located near Havre-Saint-Pierre, Que.

Highlights

• Eureka has mobilized crews for its phase 1 2026 exploration program at the Tyee titanium project in Quebec.
• Program to evaluate high-priority targets including Big Tio, NS trend and East Nugget.
• Historical surface sampling returned average grades of up to 36.07 per cent TiO2 at Big Tio.
• Multiple untested electromagnetic (EM) anomalies generated from historical airborne SkyTEM surveys to be evaluated.
• Helicopter-supported field program scheduled through June 17, 2026.
• Results expected to assist in prioritizing additional geophysical surveying and follow-up exploration activities later in the 2026 field season.

"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 Quebec," stated Danny Matthews, chief executive officer. "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 per cent TiO2 from 12 grab samples, while the NS trend target returned average grades of 31.89 per cent TiO2 across 15 grab samples and an interpreted strike length of approximately 2.3 kilometres. East Nugget returned average grades of 34.50 per cent TiO2 across three 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.

Untested SkyTEM EM anomalies

In addition to the historically identified targets, the current program will evaluate multiple additional EM anomalies generated from extensive airborne SkyTEM geophysical surveying previously completed across the project area. Numerous conductive targets identified by the surveys remain only partially evaluated or entirely untested by previous field programs. The company believes several of these anomalies warrant additional follow-up geophysical work and detailed ground evaluation.

Prospecting activities will utilize portable beep mat systems, which have previously demonstrated effectiveness in identifying massive oxide mineralization within the district. The company believes this approach may assist in rapidly evaluating both newly identified EM anomalies and recognized mineralized corridors across the project's titanium-vanadium-scandium prospective trends.

The program will include geological mapping, prospecting and rock sampling designed to refine geological interpretations and expand known mineralized trends. Results from the phase 1 program are expected to assist the company in prioritizing additional geophysical surveying and follow-up exploration activities planned for later in the 2026 field season. All rock samples collected during the program will be prepared at IOS Geosciences' facilities in Saguenay, Que., before being submitted to accredited analytical laboratories for assay and geochemical analysis.

The Tyee titanium project is located within the Havre-Saint-Pierre anorthosite complex on Quebec's North Shore, approximately 140 kilometres north of Havre-Saint-Pierre. The district hosts Rio Tinto's nearby Lac Tio deposit, one of the world's largest hard rock titanium deposits, and remains significantly underexplored despite its favourable geological setting and extensive critical metals potential.

The company also announces that it has granted an aggregate of 100,000 incentive stock options to certain consultants of the company pursuant to its omnibus equity incentive plan. The options are exercisable at a price of 45 cents per common share for a period of three years from the date of grant.
