NioBay Confirms Extension of Mineralization on Its Crevier Project and Intersects Rare Earth Elements in Its Northernmost Holes
Executive Summary
- NioBay Metals released initial intercepts from its 15‑hole, 3,324 m 2025 summer drill campaign on the Crevier project, confirming mineralization continuity over >6 km.
- Significant Nb₂O₅ grades (up to 0.354 % over 1 m) and Ta₂O₅ grades (up to 0.042 % over 1 m) were intersected, alongside high‑grade rare earth element (REE) zones (up to 8 500 ppm total REE) and notable strontium concentrations (>1 200 ppm).
- Results will be incorporated into an upcoming resource estimate and support a larger bulk sample for the next pilot test, aimed at scaling production of niobium oxide for battery manufacturers.
Key Details
- Campaign Overview
- Completed August 2025; 15 holes, total 3,324 m drilled.
-
Objective: verify continuity of Nb‑Ta mineralization in NW and SE sectors; collect material for a second pilot test (≈10× volume of first pilot).
-
Nb₂O₅ Intercepts (selected highlights)
- Hole 1532-25-01: 0.227 % over 9.90 m (116.10‑126.00 m) and 0.299 % over 4.00 m (128.50‑132.50 m).
-
Hole 1532-25-04: 0.354 % over 1.00 m (176.20‑177.20 m); 0.247 % over 11.30 m (189.50‑200.80 m).
-
Ta₂O₅ Intercepts (selected highlights)
- Hole 1532-25-01: 0.031 % over 4.00 m (128.50‑132.50 m); 0.022 % over 10.90 m (116.10‑127.00 m).
-
Hole 1532-25-04: 0.042 % over 1.00 m (176.20‑177.20 m); 0.025 % over 15.70 m (186.30‑202.00 m).
-
Total Rare Earth Elements (TREE) Intercepts
- Hole 1532-25-08: 8 500 ppm REE over 1.36 m (76.30‑77.66 m).
-
Hole 1532-25-09: multiple high‑grade zones, e.g., 7 830 ppm over 3.00 m (41.40‑44.40 m) and 5 770 ppm over 4.15 m (367.45‑371.60 m).
-
Strontium (Sr) Intercepts
- Hole 1532-25-01: several intervals >1 200 ppm, e.g., 1 540 ppm over 1.00 m (74.00‑75.00 m).
-
Hole 1532-25-02: 1 620 ppm over 1.50 m (153.05‑154.55 m); 2 320 ppm over 1.00 m (237.20‑238.20 m).
-
Resource Implication
- Intercepts will be added to historical data for an updated NI 43‑101 resource estimate.
-
Mineralized zone now extends >6 km strike length, indicating potential for a larger economic deposit.
-
Next Steps
- Bulk sample collection planned for early fall 2025 to provide representative material for the second pilot test.
- Updated resource estimate forthcoming; project slated for exclusive niobium oxide production targeting battery manufacturers.
Notable Quotes
“We are pleased to announce the initial drill results received, and to note that the mineralized zone is still open to the northwest as well as to the southeast of the known zone… The mineralized zone now extends over a strike length of more than 6 km.” – Jean‑Sébastien David, President & CEO
