MINERAL PROSPECTS FOR PROMOTING GREENFIELD AREAS
Mineral Resources: Gold - Copper - Iron - Base Metals - Rare Earth Elements Minerals
IDENTIFYING THE AREA
The area being promoted has mining potential for Copper prospecting, an essential raw material for use in various sectors of the manufacturing industry. It is a greenfield area, the basic work on which took place during the implementation of the National Geology Plan (PLANAGEO).

REGIONAL GEOLOGY
The area lies on Sheet SUL-D-33T, where the Central-West Intra-Eburnean Gneissic-Migmatitic Complex outcrops, containing foliated muscovite leucogranites, heterogeneous biotite granites, banded, sometimes migmatized and orthogneiss, and the Lubango-Munhino Gneissic-Migmatitic Complex, containing variably migmatized paragneisses and orthoderived migmatites of the Terreiro Group.
In the Basic to Intermediate Plutonic Suite of the Namibe-Lubango Region, there are occasionally foliated biotitic ± amphibole tonalites, granodiorites and granites, equigranular pink granites and leucogranites, biotitic ± amphibole granites and granodiorites, porphyroids, medium to coarse grained biotitic granites and granodiorites and fine to medium grained biotitic granites.
In and around the area, there are potential occurrences of rocks containing copper, quartz and other minerals paragenetically associated with copper.
RECENT WORK AND RESULTS
The area under promotion has aero-geophysical information on magnetometry and radiometry acquired by means of flight lines with a spacing of 1,000 m and an altitude between 80 to 120 m. This data, available from the Geological Institute of Angola, can be used as support during the development of geological-mining activities.
The following results were obtained:
- Airborne geophysics (magnetometry and radiometry);
- Systematic geological mapping at a scale of 1:250,000;
- Regional geochemistry at a scale of 1:250,000;
- Various specific studies relating to areas of special geological interest.
The following maps were produced from the airborne magnetometry and gamma spectro- metry campaign:
- Map of total magnetic field strength corrected for IGRF and reduced to the pole;
- Map of derivatives (1st and 2nd vertical derivatives of magnetic field strength);
- Horizontal gradient in Y of the magnetic field intensity reduced to the pole. The same was done for remote sensing. Terrain elevation model (DEM);
- Ternary radiometric map (K, U, Th);
- Total count radiometric map.
INFRASTRUCTURE AND SERVICES
The region is endowed with essential infrastructure and services for the development of mining projects, such as:
- The area can be accessed via National Road 280, which links the municipalities of Camu cuio and Bibala to the city of Moçâmedes;
- The Port of Namibe, Moçamedes Railway and Bibala Logistics Base can be used during all stages of geological and mining activities;
- Existence of financial services and solid telecommunications structures;
- Existence of laboratory services to support geological-mining activities, belonging to the Geological Institute of Angola, in Huíla Province;
- Electricity can be supplied from the connec tion to the National Electricity Transmission Network.
