NiobiumX Mining Outlines the Principal Exploration Target at Its Shipshaw Niobium Property, Quebec
Planned surveys and historical-core review would define the target before drilling a centre that remains untested.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
NiobiumX Mining (NIOXF) outlined an undrilled magnetic-low centre as the principal exploration target at its wholly owned Shipshaw Property in Quebec. The company plans high-resolution airborne magnetic and radiometric surveys, 3D magnetic modelling and historical-core review to define the target before drilling its centre.
Historical drilling by DIOS Exploration in 2010–2011 comprised 23 holes totalling approximately 5,850 metres, targeting surrounding magnetic rims. Every hole intercepted carbonatite, but the historical results remain unverified by NiobiumX's qualified person. Drilling is insufficient to determine mineralization dimensions or orientation, and Shipshaw has no estimated mineral resource or reserve. Nearby Niobec mineralization is not necessarily indicative of Shipshaw's geology or mineralization. Niobium remains the exploration focus, although rare earth elements are also recorded. Matthew Schwab joined the board effective immediately.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

VANCOUVER, BC / ACCESS Newswire / October 20, 2026 / NiobiumX Mining Inc. (CSE:NIOX)(FSE:O7D0)(OTCQB:NIOXF) ("NiobiumX" or the "Company") today outlines the principal exploration target at its Shipshaw Property in the Saguenay region of Quebec, and the reasons the Company has prioritized it. The Company also announces the appointment of Matthew Schwab to its Board of Directors.
Key Highlights
1. Two Magnetic Lows, One Mine: In 2010, a reinterpretation of Geological Survey of Canada magnetic data by Camille St-Hilaire for DIOS Exploration Inc. identified two low magnetic anomalies north of the Saguenay River. The first correlates with the Niobec deposit, North America's only producing niobium mine, approximately two kilometres from the Company's nearest claim. The second is largely covered by the Shipshaw Property and has never been verified. 1, 3, 9
2. What the First One Became: Niobec was discovered in 1967 by a radiometric survey during uranium exploration and has been in production since 1976. Its 2013 technical report states measured and indicated mineral resources of 629.9 million tonnes at
3. The Rims Were Drilled. The Core Was Not: The 2010-2011 program by DIOS Exploration Inc., 23 holes totalling approximately 5,850 metres, was designed around systematic drilling of the magnetic rims surrounding the carbonatite core, to a depth of approximately 125 to 150 metres. Every hole intercepted the carbonatite complex. The Company's NI 43-101 technical report concludes that the drilling to date is insufficient to determine the dimensions or orientation of the mineralization, and that the target merits further work. 2, 3, 4, 5
4. The Niobium-Bearing Carbonatite Type: Géologie Québec reports that of the five carbonatite systems it selected for characterization along the Waswanipi-Saguenay corridor, Shipshaw is the only one with a homogeneous magnesio-carbonatite composition, and that at Shipshaw the magnesio-carbonatite is the facies most mineralized in niobium. 6
Why the Company Is Focused on This Target
Carbonatite complexes in the Saint-Honoré corridor share a geophysical signature: a magnetic low, commonly accompanied by elevated thorium. That is the signature that led to Niobec. 1 At Shipshaw the same signature is present, carbonatite has been confirmed in every historical drill hole, and the centre of the magnetic low has not been drilled.2 Géologie Québec notes that carbonatite made up only about
The next step is to image the system properly. High-resolution airborne magnetics and radiometrics, 3D magnetic inversion and a re-examination of the historical core are designed to define the size, orientation and depth of the target before the first hole goes into its centre.
"There are two magnetic lows north of the Saguenay River. One of them is Niobec. The other one is ours," said Kirby Renton, President and Chief Executive Officer.1 "The earlier drilling went around the edges and hit carbonatite in every hole. Nobody has drilled the middle. That is the hole we want to drill."
Rare Earth Elements
The Shipshaw carbonatite also carries rare earth elements, as recorded in the Company's NI 43-101 technical report and in Géologie Québec bulletin BM 2024-02. The Company's exploration focus at Shipshaw is niobium. 3, 6

Appointment of Matthew Schwab to the Board of Directors
NiobiumX announces the appointment of Mr. Matthew Schwab to its Board of Directors, effective immediately. Mr. Matthew Schwab is an acclaimed exploration geologist who, in 2014 as Senior Exploration Geologist at NexGen Energy Ltd., was instrumental in the discovery of the Arrow uranium deposit located in the southwestern Athabasca Basin. Mr. Schwab was also a member of the Hathor Exploration Ltd. development team, where he contributed to the sale of the Roughrider deposit to Rio Tinto for
"Matt has been part of teams that took a target through to discovery and on to a sale," said Kirby Renton, President and Chief Executive Officer. "Shipshaw is at the stage where that experience counts, and we are pleased to welcome him to the board."

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What is NiobiumX's principal exploration target at Shipshaw?
The principal target is the undrilled centre of a magnetic low largely covered by the Shipshaw Property. Historical drilling targeted the surrounding magnetic rims rather than the centre. Existing drilling is insufficient to establish the dimensions or orientation of mineralization.
What exploration work does NiobiumX plan before drilling Shipshaw's target centre?
NiobiumX plans high-resolution airborne magnetic and radiometric surveys, 3D magnetic modelling and historical-core review. The work is intended to define the target's size, orientation and depth before drilling its centre.
How much carbonatite did historical drilling at NiobiumX's Shipshaw Property encounter?
Carbonatite made up about 6% of the rock logged in the historical holes, although every hole intercepted the carbonatite complex. DIOS Exploration's 2010–2011 program targeted magnetic rims to a depth of approximately 125 to 150 metres. The historical drilling information has not been verified by NiobiumX's qualified person and should not be relied upon.
