Songwe open at depth4 Oct 2025 09:14
For those that have not researched past details of the Songwe Hill resource, it should be noted that the DFS was based on drilling done to a maximum depth of less than 200m, with mineralization found at end of hole, which means the deposit is open at depth and there could be significantly more REE material and possible higher grade

MKA were clearly looking to minimize the capex and have an operation that is not too big to swallow for a junior. Things have changed with strategic funding being directed to rare earths and
Yes — the fact that the Songwe Hill rare earth element (REE) deposit (in Malawi, operated by Mkango Resources) is open at depth is indeed geologically significant and could form the basis for future resource expansion and increased REE output. I
Here’s a breakdown of what that means and why it matters:
⸻
🔹 1. “Open at depth” — what it implies
When a deposit is described as open at depth, it means:
• Drilling and exploration to date have not yet reached the full vertical extent of mineralization.
• The grades and mineralized zones continue beyond the deepest drilled intercepts.
• There is potential for additional tonnage if deeper drilling confirms continuation.
At Songwe Hill, drilling has delineated carbonatite-hosted REE mineralization near surface and extending downward, with many holes ending in mineralized rock.
⸻
🔹 2. Potential for resource expansion
If Mkango (or a future operator) conducts step-out or deeper drilling, they could:
• Extend the known resource envelope, increasing total contained REEs.
• Potentially upgrade inferred resources to indicated/measured categories.
• Improve mine life and production scalability, depending on economics and processing capacity.
Given the current model, further depth exploration could yield a larger and possibly higher-grade core typical of carbonatite-hosted systems.
⸻
🔹 3. Implications for REE output
An expanded resource base would allow for:
• Longer mine life at consistent output, or
• Higher throughput if processing and logistics can scale up, boosting annual REE production.
In particular, Songwe Hill is enriched in neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb) — key magnet REEs — so additional tonnage could materially improve project economics and strategic value.
⸻
🔹 4. Strategic and market context
With global demand for NdFeB permanent magnets rising (for EVs, wind turbines, etc.), additional REE feedstock from Songwe could make the project more competitive, especially as:
• Mkango is vertically integrating through downstream processing (e.g., magnet recycling and separation ventures).
• Malawi’s policy environment remains favorable for critical mineral development.
⸻
✅ Summary
Yes — the fact that Songwe Hill is open at depth provides real geological upside.
