Geophysical Survey – 2023 Results & Outlook
Introduction
As part of its technical assessment of the mining potential of Drâa‑Tafilalet region, Coppernicus Mining Company conducted a high-resolution ground magnetic survey. The objective was to better understand the geological structure of the area, identify magnetic anomalies associated with copper mineralization, and guide the next exploration phases in a targeted and efficient manner.
- Precambrian volcanic formations (andesites, rhyolites, volcanic breccias),
- A Triassic–Cretaceous cover (sandstones, basalts, dolomites, conglomerates),
- The Tibhart Formation: Campanian dolomitic sandstone, host of the known mineralization.
Surface geology indicates the presence of submeridional copper sulfide structures, hosted in or at the contact of basaltic dykes.
The survey covered 45.5 hectares, with NE–SW-oriented profiles spaced 12.5 m apart, totaling 35.5 km of measurements. Equipment and processing included:
- Overhauser magnetometers (GSM-19),
- Corrections for diurnal variations and IGRF,
- 3.125 m gridded interpolation.
Data processing included:
- Reduction to the Magnetic Pole (RTP),
- Horizontal Gradient (GH),
- Vertical Derivative (VD),
- Analytic Signal (AS),
- Tilt Derivative (TDR).
These filters enabled accurate positioning of anomalies above causative bodies and a clearer delineation of potentially mineralized zones.
The processed magnetic maps revealed:
- A main magnetic anomaly trending NNW–SSE,
- Secondary, centered, unipolar anomalies, pointing to well-defined sources,
- A high-frequency linear magnetic relief, consistent with near-surface copper sulfide structures.
The TDR filter allowed for precise mapping of the geometry and estimated depth of magnetic bodies.
The results confirm the presence of a significant magnetic structure spatially correlated with surface copper occurrences. The next recommended steps include:
- Field verification through trenching and mechanical drilling,
- High-resolution electrical tomography (chargeability and resistivity),
- Extension of the magnetic survey to the northern sector, which has not yet been covered.
Institutional Framework
This study is part of Coppernicus Mining Company’s responsible exploration program, in line with:
- ESG standards in the mining sector,
- The company’s commitment to scientific rigor and respect for local territories.
Conclusion
The 2023 geophysical campaign has successfully identified a magnetic structure with strong copper potential, warranting follow-up investigations. These results provide a robust foundation for targeting future drilling operations and fully align with Coppernicus Mining Company’s disciplined and strategic exploration approach.
