Vancouver, British Columbia--(Newsfile Corp. - August 12, 2026) - Eureka Metals Corp. (CSE: ERKA) (OTCQB: UREKF) (FSE: S580) ("Eureka" or the "Company") is pleased to report that initial interpretation of its recently completed high-resolution airborne magnetic and VLF-EM survey has highlighted broad magnetic trends across the Tyee Titanium Project in Quebec's Côte-Nord region. The new geophysical dataset is being integrated with the Company's 2026 prospecting results and historical exploration data to refine and prioritize targets for future exploration.

The survey was flown at 50-metre line spacing with 500-metre tie lines and covered approximately 2,441 line-kilometres across the Project. Eureka has also recently expanded the Tyee Project to approximately 109 km² through the staking of additional claims. The tighter line spacing provides a higher-resolution geophysical dataset that complements the Company's June 2026 prospecting program, which identified six new massive ilmenite occurrences across multiple target areas.

Highlights

• High-resolution airborne MAG / VLF-EM survey completed over the 109 km² Tyee Titanium Project.
• Approximately 2,441 line kilometres flown on 50-metre line spacing.
• High-resolution magnetic and VLF-EM datasets now integrated with historical exploration and the Company's 2026 prospecting program.
• Principal exploration target areas occur within broader magnetic trends identified across the Project.
• Survey results will support continued geological interpretation and refinement of future exploration targets.

"Our June field program demonstrated that titanium mineralization is widespread across several areas of the Tyee Project, and this new high-resolution survey gives us a much clearer picture of the broader geophysical setting around those occurrences," commented Danny Matthews, Chief Executive Officer. "What stands out is the scale and continuity of the magnetic trends across the Project. We now have a significantly improved dataset to integrate with our field results as we refine and prioritize the next generation of exploration targets at Tyee."

The airborne survey, completed by Novatem Inc., collected approximately 2,441 line kilometres of high-resolution magnetic and VLF-EM data across the entire Project.

Initial interpretation demonstrates that the Company's principal exploration target areas are situated within a broader network of regional magnetic features extending across the Project. These datasets are now being integrated with geological mapping, historical exploration data and surface sampling to improve Eureka's understanding of the geological controls on titanium mineralization and to prioritize follow-up exploration.

The VLF-EM survey provides an additional dataset for evaluating geological trends and structural features across the property. When combined with the magnetic survey and geological observations, these data will assist the Company in refining priority exploration areas and evaluating the continuity of prospective geological trends.

Next Steps

The Company is continuing to integrate the airborne geophysical data with geological mapping, prospecting observations, historical exploration data and surface sampling. This work will support the ongoing refinement and prioritization of exploration targets and help guide future field programs across the Project.
