Eureka Metals samples up to 36.87% TiO2 at Tyee Titanium Project, Quebec
Eureka Metals Corp. [CSE: ERKA; OTCQB: UREKF; FSE: S580] has released assay results from its 2026 surface exploration program at the 100%-owned Tyee titanium project, Quebec.
The 2026 program identified five new titanium occurrences with samples grading more than 35% TiO2, materially expanding the number of high-grade titanium occurrences identified across Tyee. Assay results reached 36.87% TiO2, with nine samples from the program returning more than 35% TiO2.
Importantly, the high-grade results were not limited to areas where high-grade titanium had previously been identified. The 2026 program added high-grade results across multiple areas of the project, expanding the geographic distribution of known high-grade titanium mineralization at Tyee.
Highlights: Five new titanium occurrences returned samples grading more than 35% TiO2. Nine samples returned more than 35% TiO2, with grades ranging from 35.13% to 36.87% TiO2.
The nine samples exceeding 35% TiO2 also returned consistent vanadium values of approximately 0.26% to 0.30% V2O5.
The five new occurrences expand the distribution of high-grade titanium mineralization beyond the principal areas identified through previous exploration at Big Tio, NS Trend and East Nugget.
Eureka is comparing the new high-grade occurrences with its recently completed approximately 2,300-line-km high-resolution airborne magnetics-electromagnetics-very-low-frequency survey to prioritize areas for follow-up exploration.
“The key result from this program is that we didn’t just reproduce the high titanium grades previously found at Tyee. We found them at five new occurrences,” said Danny Matthews, CEO of Eureka Metals. “We now have high-grade titanium results across a much broader area of the project. With our new airborne geophysics completed, the next step is to determine which of these new occurrences may be associated with larger targets and where we should focus the next phase of exploration.”
The 2026 exploration has expanded high-grade titanium mineralization. The 2026 surface exploration program was managed by IOS Geosciences and included prospecting across multiple areas of the Tyee property.
Field crews identified six new massive ilmenite occurrences during the program. Laboratory analysis has confirmed that five of these new occurrences returned samples grading more than 35% TiO2.
Previous exploration had established high-grade titanium mineralization at several principal areas, including Big Tio, NS Trend and East Nugget. The 2026 results demonstrate that high-grade titanium mineralization is not limited to these previously identified areas.
The 2026 results expand the geographic distribution of samples grading more than 35 per cent TiO2 beyond the principal high-grade areas identified through previous exploration.
Nine samples from the 2026 program returned greater than 35% TiO2. The nine samples also returned vanadium values ranging from approximately 0.26% to 0.30% V2O5.
Tyee is located within the Havre-Saint-Pierre anorthosite complex on Quebec’s North Shore, an iron-titanium oxide district that also hosts Rio Tinto’s producing Lac Tio ilmenite mine, approximately 65 km south of Tyee. Lac Tio has been in production since the early 1950s and is described by Rio Tinto as the world’s largest solid ilmenite deposit.
Historical published geological studies of Lac Tio have reported titanium grades generally ranging from approximately 32% to 38% TiO2. This regional context demonstrates the high titanium grades associated with ilmenite mineralization within the Havre-Saint-Pierre anorthosite complex and provides useful context for Eureka’s 2026 Tyee results of up to 36.87% TiO2.
Lac Tio is a producing mining operation while Tyee is an early-stage exploration project. Mineralization at Lac Tio is not necessarily indicative of mineralization at Tyee. The company has not established a mineral resource at Tyee, and there has been insufficient exploration to determine the continuity, dimensions, tonnage, mineralogy, metallurgical characteristics or economic potential of mineralization at the project.
Eureka recently completed approximately 2,300 line-km of high-resolution airborne magnetic and EM-VLF surveying across Tyee at 50-metre line spacing.
The company is comparing the locations of the new high-grade titanium occurrences with the airborne geophysical results and historical exploration data to prioritize areas for follow-up. This work will evaluate whether the newly identified surface occurrences correspond with geophysical targets and help determine where Eureka should focus its next phase of exploration. The company expects to provide a further update as this work advances.
Eureka Metals holds a 100% interest in the Tyee titanium project, Quebec, prospective for titanium-vanadium-scandium mineralization; an option to acquire an up-to-80% interest in the KM98 titanium project in Quebec; and an option to acquire a 100% interest in the Cabin Lake polymetallic project in British Columbia, prospective for silver-lead-zinc-gold mineralization.
