Lagerstätte Michalova
Bei Brezno, Mittelslowakei — Flache Geometrie, vollständige bestehende Infrastruktur und Abraumhalden-Gehalte von über 30 % MnO.
Flache Geometrie, starke Infrastruktur
Die Manganlagerstätte Michalova liegt in der Nähe der Stadt Brezno in der Mittelslowakei. Die Lagerstätte besitzt ein flaches Oxiderzflöz, das in der historischen Schätzung enthalten ist, sowie eine tiefere Karbonaterzlage von 5–30 m Mächtigkeit, die in den historischen Berechnungen weitgehend ausgeschlossen wurde — was ein erhebliches Erweiterungspotenzial bedeutet.
Beprobung von Abraumhalden hat Gehalte von über 30 % MnO ergeben, was darauf hindeutet, dass selbst verworfenes Material aus historischen Bergbauoperationen erheblichen Mangangehalt aufweist. Die sanft einfallende, flache Lagerungsgeometrie innerhalb des Breznianska-Beckens ermöglicht den Einsatz konventioneller, kostengünstiger Abbaumethoden.
Die historische Ressource beläuft sich auf insgesamt 10.406.260 Tonnen bei einem durchschnittlichen Gehalt von 9,49 % Mn, klassifiziert unter dem GKZ-System über drei Ressourcenblöcke (M-1, M-2 und M-3).
- Location
- Bei Brezno, Region Banská Bystrica, Mittelslowakei
- Ore Types
- Flaches Oxiderzflöz (in Schätzung enthalten) + tiefere Karbonaterzlage 5–30 m Mächtigkeit (weitgehend ausgeschlossen)
- Geological Setting
- Breznianska-Becken — sanft einfallend, paläogene Sedimente bis ~500 m Tiefe
- Key Advantage
- Geringe Tiefe, vollständige Infrastruktur (Bahn, Straße, Strom), unterstützende Gemeinde, Abraumhalden >30 % MnO
Ressourcenblöcke
Three resource blocks classified under the GKZ system (1993).
| Block | Tonnen | Grade (%Mn) |
|---|---|---|
| Block M-1 | 813,082 | 9.49% avg |
| Block M-2 | 9,586,655 | 9.49% avg |
| Block M-3 | 6,523 | 9.49% avg |
| GESAMT | 10,406,260 | 9.49% Mn |
*GKZ classification (1993). NOT NI 43-101 compliant. Deeper carbonate layer (5–30 m thick) largely excluded — significant expansion potential.

Geological Setting & Growth Potential
Ore Types & Geometry
- Shallow Oxide Ore
- Included in the historic 10.4 Mt estimate. Oxide seam at shallow depth, accessible by conventional mining methods within the Breznianska Basin.
- Deep Carbonate Layer
- A 5–30 m thick carbonate ore seam sits beneath the oxide. Largely excluded from the historic estimate — this represents the primary expansion opportunity.
- Basin Structure
- Gently dipping flatbed — Breznianska Basin, Paleogene sediments extending to ~500 m depth. Favorable geometry for systematic extraction.
Expansion Potential
- Block M-2 Upside
- Block M-2, which accounts for 92% of the total resource (9.59 Mt), has only limited historical drill testing. Significant room for resource upgrade with modern drilling.
- Deep Carbonate Excluded
- The entire deep carbonate seam (5–30 m thick) was excluded from the 1993 GKZ estimate. Including this layer could materially increase the resource base.
- Regional Prospectivity
- NW and SE areas within the licence are prospective per Hutianske Formation outcrops. Additional exploration targets identified but untested.
Michalova Licence & Infrastructure
Historic drill hole distribution, regional infrastructure context, and 3D geological interpretation of the Michalova deposit.
Planned Drilling Program
A confirmatory drilling program is planned for Q2 2026 at Michalova to twin historical drill holes and collect metallurgical samples.
Target Start
Confirmatory drilling program designed to twin historical holes and validate GKZ-era data with modern core samples.
Drilling Method
Diamond core drilling to provide high-quality subsurface samples for geological and metallurgical analysis.
Metallurgical Samples
Samples to be collected for laboratory testing to evaluate processing characteristics and support future NI 43-101 reporting.
