1. Executive Summary

Strataprobe has completed a comprehensive ML-driven mineral exploration analysis of the Lubudi Mining Permit 13628 — a 1,353.86 ha (13.54 km²) concession in Lualaba Province, Democratic Republic of the Congo. The permit lies within the Central African Copperbelt — the world's largest sediment-hosted Cu-Co province, hosting roughly 10% of global Cu reserves and over 50% of global Co reserves — in the Katanga Supergroup of the Lufilian Arc fold-thrust belt.

Using cloud-free Sentinel-2 satellite scenes from the 2024 dry season, we extracted 12 spectral indices at 10–20 m spatial resolution and processed them through a six-method ML pipeline comprising PCA/Crosta mineral mapping, Spectral Angle Mapper lithology classification, Isolation Forest anomaly detection, XGBoost refinement, fuzzy logic prospectivity modelling, and structural lineament analysis.

The ensemble consensus identified prospective drill targets confined strictly to the permit boundary. The dominant prospective commodity across the area is Copper, with strongly co-located Cobalt signatures consistent with the Mines Series stratigraphy of the Roan Group. Distinct gossan, clay-alteration, and Fe-Mn oxide responses suggest an oxidised cap over a sulfide-bearing root — the classic exploration target in this district.

3. Geological Setting

The permit lies within the Central African Copperbelt of southern DRC — the world's premier sediment-hosted stratiform Cu-Co province. Mineralisation is hosted in the Neoproterozoic Katanga Supergroup, deformed by the Pan-African Lufilian Arc orogeny. The Copperbelt accounts for the majority of global Cobalt production and a significant share of global Copper output, with deposits typically grading 2–5% Cu and 0.1–0.5% Co.

The stratigraphic succession in this district comprises the Roan Group (R1–R4 — hosting the productive Mines Series including R.A.T., dolomitic shales, siliceous dolomites, and the ore-bearing Black Mineralised Series), the Mwashya Group, the Nguba Group (including the "Grand Conglomérat" diamictite), and the Kundelungu Group. Cu-Co mineralisation occurs predominantly as stratabound disseminations and replacements of carbonaceous, dolomitic siltstones and shales. Primary sulfides are typically weathered in the upper 30–100 m to oxide ore (malachite, chrysocolla, heterogenite), forming the high-grade supergene blankets that dominate current open-pit mining.

At the Lubudi PE 13628 location (centred near 25.97°E, 10.49°S), the area sits along the southern flank of the Lufilian Arc. Surficial expression of mineralisation often includes vivid green malachite staining, black heterogenite crusts in karstic dolomite cavities, and Fe-Mn oxide gossans over sulfide roots. Lateritic weathering profiles can extend 30–120 m below surface, hosting significant Co-bearing oxide ore.

4. Methodology — 10-Step ML Pipeline

Click each step to expand:

1. Sentinel-2 L2A Composite

Cloud-free dry-season median composite from Google Earth Engine using SCL band cloud/shadow masking. Produces analysis-ready surface reflectance.

2. 12 Spectral Indices

Ferric, Ferrous, Gossan, Laterite, Iron Oxide, Clay/Hydroxyl, Silica, Mafic, Carbonate, NDVI, Moisture, Slope — each tuned to detect specific mineralogical signatures.

3. PCA / Crosta Method

Principal Component Analysis with Crosta technique to isolate iron-oxide and hydroxyl-mineral feature loadings. The loadings identify which PCs concentrate the alteration signal.

4. Spectral Angle Mapper (SAM)

Cosine distance between each pixel's spectrum and 9 reference Copperbelt endmember spectra (malachite/chrysocolla, heterogenite, Cu-Co gossan, dolomitic shale, Mines Series siltstone, Kundelungu sandstone, lateritic cap, background, vegetation).

5. Isolation Forest

300-tree ensemble, 5% contamination, unsupervised — identifies multivariate spectral outliers without labels.

6. XGBoost Refinement

Gradient-boosted classifier trained on Isolation Forest labels, producing sharper anomaly probabilities and feature-importance rankings.

7. Fuzzy Logic Prospectivity

Three commodity-tuned weighted index stacks (Cu, Co, Polymetallic) — geological knowledge encoded as soft logical combinations.

8. Structural Lineament Analysis

Canny edge detection + probabilistic Hough line transform on SRTM slope derivative. Identifies fractures, faults, and lithological contacts that control fluid flow.

9. Ensemble Consensus

Weighted stack: Isolation Forest (20%) + XGBoost (20%) + Fuzzy (20%) + PCA iron (15%) + SAM mineral max (15%) + Lineament density (10%).

10. In-Polygon Target Extraction

Local maxima detection on the ensemble surface within the permit polygon, with strict point-in-polygon verification. Targets ranked by score and assigned Critical/High/Medium/Low priority.

5. Spectral Index Analysis — All 12 Indices

Twelve domain-specific spectral indices were computed at native Sentinel-2 resolution (10–20 m, resampled to a common grid). Each index targets a specific mineralogical or environmental signature relevant to Central African Copperbelt exploration. Tap any index for a full-size view; toggle the matching overlay on the interactive map (Section 2) to see its spatial distribution geo-referenced over the satellite basemap.

Index Explorer

Each card explains the formula, the mineralogical sensitivity, and the Copperbelt-specific exploration relevance.

Ferric Iron

B4 / B2 — sensitive to Fe³⁺-bearing oxides (hematite, goethite). High values = oxidised Cu/Fe minerals (a Copperbelt supergene marker).

Ferrous Iron

B11 / B8A — proxy for reduced Fe²⁺ in unweathered sulfides and primary mafic minerals.

Gossan

B4 × B11 / B2 — pinpoints surface oxidation of sulfide bodies. The single highest-value index for Copperbelt sulfide-cap targeting.

Laterite

B11 / B12 — detects Fe-Mn-Al residual lateritic profiles that host supergene Co (heterogenite, asbolane).

Iron Oxide

B4 / B2 normalised — broader Fe³⁺-oxide proxy; complements Ferric Iron.

Clay / Hydroxyl

B11 / B12 — Al-OH / Mg-OH bearing minerals (kaolinite, sericite, chlorite). Marks hydrothermal alteration around Cu sulfides.

Silica

B11 ratio — silicification associated with replacement-style mineralisation and felsic intrusives.

Mafic

B12 / B8 — Mg-Fe rich rocks; useful for delineating ultramafic/mafic units.

Carbonate

B11 / B12 — Mg-CO₃ host rocks. The dolomitic Mines Series is the prime Copperbelt host.

NDVI

(B8 − B4)/(B8 + B4) — vegetation cover. Areas of low NDVI are stressed/sparse vegetation typical of metalliferous soils.

Moisture

(B8A − B11)/(B8A + B11) — surface moisture / shallow water table; useful for masking false anomalies.

Slope

SRTM-derived slope (degrees) — controls erosion of weathered cap and exposure of fresh rock.

7. Commodity-Specific Prospectivity

Three fuzzy-logic prospectivity models calibrated for Central African Copperbelt mineralisation styles:

Copper (Cu): Weighted toward gossan index (sulfide weathering caps — 25%), ferric iron (oxidised Cu-bearing minerals — 20%), clay/hydroxyl (malachite, chrysocolla, sericitic alteration — 20%), iron oxide (15%), inverse NDVI (10%), and slope (10%). Targets the supergene oxide blanket overlying primary sulfide mineralisation in the Mines Series.

Cobalt (Co): Emphasises iron oxide (Fe-Mn rich heterogenite zones — 25%), ferrous iron (20%), laterite index (Co-bearing oxide laterites — 20%), gossan index (15%), mafic index (10%), and inverse NDVI (10%). Heterogenite (CoOOH) and asbolane develop dark Mn-Fe-oxide crusts in karstic cavities and lateritic profiles.

Polymetallic (Cu-Co-U-Zn-Ag): Focuses on gossan (25%), clay alteration (20%), carbonate (dolomitic host indicator — 15%), silica (15%), ferric iron (10%), inverse NDVI (10%), and slope (10%). Captures the full spectrum of stratiform Cu-Co with associated U, Zn, Pb and Ag commonly enriched in the Copperbelt sediment-hosted system.

10. Recommended Drill Programme

Phase 1 — Ground-Truthing (1–2 weeks)

Geological mapping and surface sampling at all Critical and High priority targets
Portable XRF analysis for Cu, Co, Fe, Mn, U, Zn, S
Detailed structural mapping along Lufilian-aligned thrust contacts and transfer structures
Soil geochemistry on 50 m grid spacing; supplement with termite-mound sampling (Copperbelt-proven)

Phase 2 — Diamond Core Drilling (4–6 weeks)

Each drill collar is positioned within the Lubudi PE 13628 boundary, oriented at azimuth 20° with a dip of -60° to intersect the SSW-dipping Mines Series stratigraphy at near-orthogonal angles. NQ-size core (47.6 mm) recommended for full geological logging and Cu-Co assay sampling.

Phase 3 — Follow-Up & Step-Out (6–8 weeks)

Contingent on Phase 2 results, expand drilling to Medium priority targets and step-out holes to delineate ore body extent. Holes planned using Strataprobe TargetMax to maximise ore intersection while minimising total metres drilled.

11. Conclusions & Next Steps

The Strataprobe ML analysis of the Lubudi PE 13628 has identified 72 prospective drill targets within the 1,353.86-hectare permit boundary in the Central African Copperbelt of Lualaba Province, DRC. The analysis leveraged Sentinel-2 satellite scenes, 12 spectral indices, and 6 independent ML methods to produce a robust, multi-method ensemble prospectivity assessment. All targets are confined strictly within the permit boundary.

Key Findings

25 high-confidence targets warrant immediate follow-up
Copper (Cu) signatures dominate, with widespread oxide-zone responses
Cobalt (Co) signatures are co-located with Cu anomalies, consistent with stratiform Mines Series host
Structural lineaments suggest Lufilian-aligned fluid corridors at several target locations
Spectral Angle Mapping confirms lithological matches to malachite/chrysocolla, heterogenite, and Cu-Co gossan reference spectra
The SSW dip of the Katanga succession supports angled drilling oriented at azimuth 20°

Recommended Immediate Actions

Commission ground-truthing field visit to Critical and High priority targets
Collect surface XRF samples for Cu-Co pathfinder elements (Cu, Co, Fe, Mn, U, Zn, S)
Begin DRC environmental impact assessment (Étude d'Impact Environnemental) and drill permit applications
Engage Strataprobe for TargetMax drill planning optimisation
Plan Phase 2 core drilling programme (est. 8–12 holes, 100–250 m depth each)

12. Appendix — Data Sources & Methodology Notes

Data Sources

Satellite imagery: Copernicus Sentinel-2 Level-2A (surface reflectance), via Google Earth Engine
Terrain data: NASA SRTM 30 m DEM
Compute: Google Earth Engine + local Python (sklearn, XGBoost, OpenCV, ReportLab)
Cloud filtering: SCL Scene Classification Layer (cloud + cirrus + shadow exclusion)
Composite: Per-band median over 2024 dry season (April–October)

Methodology Notes

PCA / Crosta Method

Principal Component Analysis transforms the multi-dimensional spectral data into uncorrelated components. The Crosta technique identifies which components are most loaded on iron-oxide and hydroxyl mineral features.

Spectral Angle Mapper (SAM)

Cosine angle between each pixel's spectral signature and Copperbelt endmember spectra. Lower angles = higher similarity to mineralised rocks.

Isolation Forest

Ensemble of 300 isolation trees, contamination = 5%. Unsupervised — no labels required.

XGBoost Refinement

Gradient-boosted decision trees trained on Isolation Forest labels. Outputs anomaly probability + feature importance.

Fuzzy Logic Prospectivity

Expert-defined weighted index stacks per commodity. Knowledge-driven complement to data-driven ML.

Structural Lineament Analysis

Canny edge detection on slope-derivative + Hough line transform + Gaussian smoothing → lineament density surface.
