Millennial Potash Intersects 220m of Potash Mineralization in Drillhole BA-001-EXT at Its Banio Potash Project in Gabon
Executive Summary
- Drillhole BA‑001‑EXT intersected ~112.5 m of carnallitite seams at an average grade of 15.9 % KCl using a 13 % cut‑off, markedly thicker than the ~70 m cumulative thickness reported from prior holes (BA‑002‑EXT and BA‑003).
- The total potash‑bearing interval (no cut‑off) is 220.25 m averaging 10.4 % KCl; with the 13 % cut‑off the cumulative seam thickness is 112.46 m at 15.9 % KCl.
- Results suggest strong continuity of potash horizons, extending the known strike length to ~4 km (potentially ~8 km after BA‑004) and could materially increase the Banio Project’s resource tonnage and upgrade portions of the existing Mineral Resource Estimate.
Key Details
- Hole Information – BA‑001‑EXT is an extension of 2017 hole BA‑001, drilled to 678 m (original depth 364 m). Six evaporite cycles (II–VII) were intersected from ~362 m to 657 m.
- Cumulative Potash Thickness (13 % KCl cut‑off) – 112.46 m total seam thickness; average grade 15.9 % KCl.
- Cumulative Potash Thickness (no cut‑off) – 220.25 m total interval; average grade 10.4 % KCl.

Total (13 % cut‑off): 112.46 m at 15.92 % KCl
No Cut‑Off Summary
-
Total interval: 220.25 m, average grade 10.4 % KCl across cycles II–VII.
-
Comparison to Prior Holes:
- BA‑001‑EXT cumulative seam thickness (112.5 m) vs. ~70 m in BA‑002‑EXT & BA‑003.
-
Average grade consistent with 2024 MRE (≈15.9 % KCl).
-
Resource Implications:
- Extends known potash strike length to ~4 km; pending BA‑004 results could double to ~8 km.
- Potential to add significant tonnage to existing Indicated (657 Mt @ 15.9 % KCl) and Inferred (1,159 Mt @ 16 % KCl) resources.
-
May enable upgrade of portions from Indicated → Measured and shift Inferred → Indicated in a future updated Mineral Resource Estimate.
-
Next Steps:
- Await analytical results for BA‑004 core samples.
- Selected samples to undergo dissolution and geotechnical testing for inclusion in upcoming Feasibility Study.
Notable Quotes
“Millennial is excited to announce the assay results for hole BA‑001‑EXT, which showed over 50 % thicker cumulative potash seams than what we drilled last year… The extensive potash mineralization … has the potential to significantly boost the project's potash resources.” – Farhad Abasov, Chair of the Board
