Heliborne Magnetic Survey Reveals Internal Architecture of the Oka Carbonatite

Nio Strategic Metals Inc. (NIO) has released results from a 2023 heliborne magnetic and radiometric survey conducted over its 100%-owned Oka property in Quebec. The survey covered 921 line-kilometres and integrated 70 years of historical data to map the 3D architecture of the Oka carbonatite complex.

Technical interpretation identified three major shear zones (C1, C2, C3) and five magmatic dykes in the North Ring, specifically the Husereau, Manny North, Manny, Bond, and Central Structure. Magnetic inversion suggests these dykes may connect at depth, specifically at 800 metres and beyond.

A strong correlation was identified between rare earth element (REE) minerals—ancylite, bastnäsite, and monazite—and thorium/uranium anomalies. Historical samples from the area have shown grades ranging from 1.5% to 4% total rare earth oxides.

The technical team has recommended a nine-hole reconnaissance diamond drilling program totaling approximately 4,460 metres in the North Ring to target significant REE concentrations, with niobium as a secondary target. The company is actively working with local stakeholders to secure an Authorization for Impact-Causing Exploration Work (ATI) and has engaged GHD Environnement to guide transparency.

Nio Strategic Metals Inc. (NIO) released information that represents a logical and expected progression following its August 2026 metallurgical study, which confirmed improved niobium recovery and rare earth element (REE)/phosphate by-product potential. By mapping the internal architecture and identifying structural controls for mineralization, the company is de-risking its upcoming drill program and establishing clear targets for capital deployment.

The announcement does not contain genuinely new, unexpected, or market-moving information. Instead, it confirms management's stated exploration plan and aligns with prior-period context regarding the project's technical advancement. The impact on the stock is incremental, as the drill program is a standard next step for a pre-revenue explorer and does not immediately alter the company's financial trajectory or valuation.

Nio Strategic Metals Inc. (NIO) is a pre-revenue junior explorer focused on the Oka niobium and rare earths project in Quebec, Canada. The company’s flagship project involves a dual development strategy: constructing a state-of-the-art underground mine with a minimal environmental footprint and processing historical tailings to restore the site and recover value.

Nio Strategic Metals is targeting the growing global demand for high-strength low-alloy (HSLA) steel and ferro-niobium, positioning itself as a non-Asian source for the market. The project is currently in the advanced exploration and permitting stage, awaiting social acceptability and regulatory certificates to move toward feasibility and construction.
