The Garneau Titanium Project Features Ilmenite-Rich Boulder with Grab-Sample Assays of 65.1% Fe₂O₃, 32.4% TiO₂, and 2,260 ppm Vanadium

SAGA Metals Corp. (TSX-V: SAGA) (OTCQB: SAGMF) (FSE: 20H), a North American exploration company focused on critical mineral discoveries, is pleased to announce that it has completed the acquisition from Rio Tinto Exploration Canada Inc of a 100% interest in the Garneau project comprised of 120 claims covering 6,450.54 hectares located near Havre-Sainte-Pierre, Quebec. RTEC is a Canadian subsidiary of the Rio Tinto Group (NYSE: RIO) (LSE: RIO) (ASX: RIO).

Garneau Project Highlights

• The Garneau Project is located approximately 120 km north of deep-sea port of Havre-Saint-Pierre and 80 km north of Rio Tinto’s Lac Tio ilmenite mining operation.
• Rio Tinto’s work at Garneau advanced the property from conceptual targeting to a defined, soon drill-ready geophysical anomaly.
• The combination of scale, geological setting, and confirmed high-grade ilmenite float grab sample returning 32.4% TiO₂ established the project as a credible analogue to known Fe–Ti deposits in the district.
• Recently completed Hydro-Québec access road, located within 4.5 km of the project, has significantly improved regional access and logistics.

Michael Garagan, CGO & Director of SAGA Metals commented:

“The acquisition of the Garneau Project from Rio Tinto marks a significant strategic advancement for SAGA Metals. We have secured a highly prospective titanium asset in Quebec’s premier ilmenite district, located in the same anorthosite complex as Rio Tinto’s world-class Lac Tio operation. The geophysical signature on the Garneau property represents a clear target for further exploration. Not only does the geophysical signature display a basin-like morphology directly comparable to Lac Tio, but a massive, ilmenite-rich boulder returning a sample of 32.4% TiO₂ is a very encouraging start to the project.

We are equally excited by the major infrastructure advantages now in place, including the recently completed Romaine hydroelectric complex and the new Hydro-Québec access road located only 4.5 km from the property. This rare combination of exceptional geology and modern regional infrastructure has all t he hallmarks of the Radar Project—significantly enhancing the project’s potential and adding the growing Ti complex benefiting SAGA’s shareholders.”

Geology

The Garneau Project is within Havre-Saint-Pierre Anorthosite Complex of Quebec, a globally significant titanium-bearing district. The region hosts Rio Tinto’s renowned Lac Tio Mine deposit, one of the highest-grade hard rock titanium operations globally [1].

The Havre-Saint-Pierre anorthosite suite, located within Québec’s Grenville Province, is a globally recognized geological setting for magmatic iron–titanium (Fe–Ti) oxide mineralization. Formed during Mesoproterozoic AMCG (anorthosite–mangerite–charnockite–granite) magmatism, the suite hosts a range of ilmenite- and hemo-ilmenite-dominated deposits, including the world-class Lac Tio operation.

Mineralization in the district occurs as massive ilmenite bodies, as well as layered or disseminated Fe–Ti–P systems containing associated vanadium and apatite. This well-established metallogenic environment underpins the strong exploration potential of the region, where large-scale geophysical anomalies and ilmenite-bearing occurrences are considered indicative of prospective Fe–Ti oxide systems.

The Garneau Target: Exceptionally Intense Magnetic Anomaly

The Garneau Project is in an area of covered by a mantle of glacial till and sediment, covering over 85% of the project area. Outcrops are sparse. Airborne geophysical surveys by Rio Tinto detected a large and coherent magnetic anomaly. Exploration has outlined a distinctive ovoid-shaped magnetic low measuring approximately 4.5 km by 7.5 km, positioned along the central axis of the anorthosite complex—an environment considered highly prospective for ilmenite-bearing systems.

Lac Tio is the clearest analogue. Québec governme nt work describes the Lac Tio hemo-ilmenite orebody as producing sharply defined negative magnetic anomalies, with magnetic intensity about 3,500 gammas below the surrounding rocks, and attributes that negative response to the orebody’s own magnetic polarization/remanence. More recent work on Allard Lake hemo-ilmenite also emphasizes the high and stable natural remanent magnetization of these ores.

Lac Tio, currently in production, produces ore that is 60-80% hemo-ilmenite [2]. Titanium is the main commodity mined, however iron and REEs like Scandium (Sc) are economic byproducts. The minable horizon at Lac Tio is a about 1 km wide by 150-300 m thick, funnel shaped mass of hemo-ilmenite within anorthosite.

Drill Testing Recommended by Rio Tinto’s Garneau Report

Drilling is required to determine the source, continuity, and economic potential of the magnetic low and to confirm whether the high-grade boulder reflects a larger mineralized body at depth. The working interpretation is that Garneau may represent the same kind of remanence-dominated Fe–Ti oxide target. Garneau’s magnetic low should not be read as a lack of magnetism; in this district, it can be exactly the sort of signature associated with major hemo-ilmenite bodies such as Lac Tio.

Confirmation of titanium potential of the intense magnetic response came during the initial follow-up mapping and sampling work that discovered a boulder of massive h emo-ilmenite, grading 65.1% Fe₂O₃, 32.4% TiO₂, and 2,260 ppm vanadium.

The Rio Tinto Garneau report notes that surface work is limited by the glacial cover. The report recommends that the next phase of work should focus on drill testing. Specifically, it states that drilling should be carried out in several areas of the large magnetic feature to obtain better geological and structural information and to seek the source of the ilmenite boulder found on the property.

Rio Tinto’s History at the Garneau Project

The Garneau Project was assembled by Rio Tinto as part of a broader exploration strategy targeting iron–titanium (Fe–Ti) mineralization within the Havre-Saint-Pierre anorthosite suite, a globally significant district that hosts deposits such as Lac Tio.

In 2022, Rio Tinto completed a first-pass exploration program consisting of airborne magnetic and Versati le Time Domain Electromagnetic (VTEM) Survey, 747 line-km with additional field work, mapping and sampling. This work defined a large, coherent circular magnetic low measuring approximately 4.5 km by 7.5 km, interpreted as a significant geological feature within the anorthosite complex.

After the geophysical work, fieldwork located a large, massive ilmenite boulder, confirming the presence of Fe–Ti mineralization within the system. The top grab sample (40483102) was a massive ilmenite-rich boulder, of solid oxide. The boulder returned assays of 65.1% Fe2O3, 32.4% TiO2, and 2260 ppm vanadium [3].

At the conclusion of Rio Tinto’s work, the Garneau Project remained at an early exploration stage, with no drilling completed and limited bedrock exposure across the property. While the source of the magnetic anomaly was not identified, the scale, geometry, and geological context of the feature led to its classification as a high-priority d rill target. Rio Tinto’s program effectively advanced the property from regional targeting to a defined, drill-ready opportunity, leaving the key test of subsurface mineralization to future exploration.

The Havre-Saint-Pierre Titanium District and Rio Tinto’s Lac Tio Mining Operation

The Havre-Saint-Pierre district on Québec’s North Shore is one of North America’s most significant titanium mining regions, anchored by Rio Tinto’s Lac Tio mine, located approximately 43 kilometres northeast of the town. Lac Tio is widely recognized as the largest hard-rock ilmenite deposit in the world and serves as the upstream cornerstone of Rio Tinto’s Québec iron and titanium operations [2].

The mine benefits from an established logistics chain in which ore is processed on site, transported by rail to Havre-Saint-Pierre, and then shipped into Rio Tinto’s broader Québec processing network, cre ating a rare combination of scale, operational continuity, and integrated industrial infrastructure.

The significance of Lac Tio is reinforced by both its scale and its longevity. Exploration in the Allard Lake–Havre-Saint-Pierre area accelerated during the 1940s, the Lac Tio orebody was identified in 1946, and production began in 1951 following construction of rail infrastructure linking the mine to the coast [5]. More than seventy years of continuous operation have established Lac Tio as one of the world’s defining hard-rock titanium mines and a clear demonstration of the district’s capacity to support long-life, large-scale extraction and transport of ilmenite ore. Today, the operation remains an important part of Rio Tinto’s global titanium feedstock supply chain and continues to underpin the district’s industrial relevance.

Beyond the producing mine, the broader Havre-Saint-Pierre area remains highly prospective because Lac Tio sits within a larger anorthosite-hosted mineralized system rather than an isolated occurrence. The district has long been recognized for iron-titanium oxide mineralization, which continues to attract exploration and claim staking by companies including Eureka, Go Metals, Blackbird Critical Metals, and North Atlantic Titanium. These projects vary in stage and focus, ranging from district-scale titanium-vanadium targeting to historically explored hard-rock ilmenite ground near Lac Tio, but collectively they reflect continued confidence in the wider geological corridor surrounding the operation [6].

Well-Developed Regional Infrastructure

The Garneau Project is located near the Romaine hydroelectric complex (Complexe hydroélectrique de la Romaine), a major $7.4 billion (CAD) project developed by Hydro-Québec on the Romaine River in the Côte-Nord region of Quebec, Canada, north of Havre-Saint-Pierre. It consists of four generati ng stations (Romaine-1, -2, -3, and -4) with a total installed capacity of 1,550 MW and average annual output of 8.0 TWh. Construction began in 2009, marking one of Quebec’s largest hydro developments since James Bay. The full complex was officially inaugurated in October 2023 [4].

A defining strength of the district is its infrastructure base, which is considerably more advanced than that of many northern exploration camps. Havre-Saint-Pierre functions as the coastal logistics hub for the region, supported by established rail access from Lac Tio and marine access along the North Shore. Together, the existing mine-rail-port network, access to reliable low-carbon electricity, and the presence of a long-standing world-class operation give the Havre-Saint-Pierre district a strong foundation for continued mining activity and future development.
