NORTH AMERICAN NIOBIUM ADDS TO QUEBEC NIOBIUM AND RARE EARTHS HOLDINGS

North America Niobium and Critical Minerals Corp. continues to increase its exposure to alkaline intrusive settings associated with niobium and rare earth element geochemical anomalies identified by government data sets from the government of Quebec. This is in keeping with North American Niobium's strategic focus on identifying alkaline systems capable of producing niobium-rare earth element mineralization

The company has staked approximately 4,222 hectares, consisting of 73 mineral claims, 45 kilometres (km) northwest of La Tuque, Que. (Miskam). Transfers of 21 of the 73 mineral claims remain pending approval. The property is approximately two km west of Sabot and shares a similar geological setting. Highly anomalous bottom lake sediments and rocks samples collected by the government on Miskam align with mapped syenitic intrusions and favourable host rocks, supporting a silicate-alkaline exploration model for niobium-rare earth element mineralization.

"We saw an opportunity to secure this land package based on intriguing signs in a favourable geological environment, with nearby prospects that support our targeting concept," said Murray Nye, chief executive officer. "Our technical team believes the acquisition made sense, so we moved to purchase the claims. The geological setting we're targeting is consistent with alkaline intrusive environments that can host niobium-rare earth elements mineralization. Importantly, we expect the permitting pathway and stakeholder engagement approach for this area to be consistent with our established Quebec process, which we believe will help streamline near-term planning."

Highlights:

• Acquired 73 mineral claims over 4,222 hectares in the La Tuque area, expanding the company's footprint within the Grenville province'
• Targeting niobium-rare-earth-element (REE) potential in an alkaline system supported by Quebec government data, including SIGEOM and PRO 2009-03 (Labbe, 2009) bottom-lake sediment geochemistry;
• Highly anomalous (approximately 99th percentile) niobium-lanthanum-yttrium geochemical responses in the area stand out within the referenced data set and are considered prospective in the context of alkaline niobium-REE systems in Quebec;
• Mapped syenitic intrusions near potentially silica-rich metasediments (quartzites and other metasedimentary units) are consistent with an alkaline silicate niobium-REE exploration model;
• Next steps include field validation and sampling to refine targets and prioritize follow-up work.

Strategic rationale and exploration model

The company is focused on identifying alkaline systems capable of producing niobium-REE mineralization. This concept draws on the exploration framework described by Beard et al. (2022) and includes:

• A typically oval alkaline intrusive complex can provide several pathways to concentrate niobium and rare earth elements such as:
  • Near-surface and contact zones where alkaline melts and late-stage fluids react with silica-rich host rocks, potentially creating mineralized breccias, xenoliths and sheeted syenite bodies;
  • Mineralization within the intrusion where the magma becomes layered and progressively more evolved;
  • Late-stage, highly evolved intrusive phases (central/apical plugs, sheets and dikes, and related pegmatite or hydrothermal zones) where rare earths and other critical elements may be concentrated as the system cools and differentiates;
• Carbonatite-associated niobium-rare earth element systems.

The company has reviewed Quebec government bottom-lake sediment geochemistry available through SIGEOM, including information reported in PRO 2009-03 (Labbe, 2009). The data set includes 11,719 sample locations within the company's area of interest.

A cluster of anomalous bottom-lake sediment in niobium, lanthanum and yttrium has been identified occurring directly over, and immediately adjacent to, a mapped alkaline intrusive oval-shaped body interpreted to be at least seven by 10 km. The anomalous response appears to be strongest near the interpreted intrusion and extends outward into adjacent metasedimentary units of the Wabash complex. Two rock samples collected by government geologists also returned elevated total rare earth element values, grading 713.9 parts per million (ppm) and 785.67 ppm.

Taken together, this spatial association between the bottom-lake sediment anomaly pattern, the interpreted alkaline intrusive body and favourable host rocks makes for a compelling, early-stage niobium-REE target on the property.

Note that the technical rationale described herein is interpretive and early stage, and is based primarily on public-domain government mapping and geochemical data sets, and the presence of regional mineral occurrences. These indications do not confirm the presence of mineralization on the property and there has been insufficient exploration on the property to define a mineral resource.
