Target Generation Map — Ghana

To create a target generation map for Ghana, import your GH claims or data as GeoJSON, assign the appropriate layer role for automatic styling, set the Satellite basemap, and export as PNG or PDF. The entire process takes 15–30 minutes with no GIS experience required.

About Mining in Ghana

Ghana is Africa's largest gold producer and consistently ranks among the world's top ten gold-producing countries. The Birimian Greenstone Belt hosts several multi-million-ounce gold deposits with geological similarities to the Abitibi Belt in Canada, and the country's established regulatory framework attracts significant international junior exploration investment.

Key minerals: gold, bauxite, manganese, diamonds, iron ore, lithium. Notable deposits: Obuasi, Ahafo, Akyem, Asanko. Mining districts: Ashanti Gold Belt, Birimian Greenstone Belt, Western Region, Brong-Ahafo.

The Minerals Commission of Ghana administers mineral rights in Ghana. Claim data is accessible through Minerals Commission Mining Cadastre.

What is a Target Generation Map?

A target generation map integrates multiple datasets — geophysical anomalies, geochemical results, structural features, and historical workings — to visually communicate which areas have the highest exploration priority. These maps are central to project generation pitches and technical program planning.

How to Create a Target Generation Map for Ghana

  1. Import target polygon outlines as GeoJSON
  2. Import anomaly extents as a separate GeoJSON layer
  3. Assign Target Areas and Anomalies roles
  4. Import fault and structure lines
  5. Use Outside Shade on key target polygons to focus attention
  6. Add labels for each named target
  7. Overlay on Satellite basemap to show terrain context
  8. Export at high resolution (3×) for technical presentations

Frequently Asked Questions

What file format do I need for Ghana mineral claims data?
Ghana mineral claims boundaries are available from Minerals Commission Mining Cadastre and can typically be downloaded as Shapefiles or KML. Convert these to GeoJSON at mapshaper.org before importing into Exploration Maps.
Who regulates mineral claims in Ghana?
Mineral claims in Ghana are regulated by the Minerals Commission of Ghana. All tenure and claims data can be queried through Minerals Commission Mining Cadastre.
What minerals are typically mapped in Ghana?
Ghana is known for its gold, bauxite, manganese, diamonds deposits. Key producing and exploration-stage properties include Obuasi, Ahafo, Akyem. The main mining districts are Ashanti Gold Belt, Birimian Greenstone Belt, Western Region.
Can I export a Ghana target generation map for a JORC Code / NI 43-101 report?
Yes. Exploration Maps exports PNG and PDF at 2–3× pixel ratio, suitable for inclusion in JORC Code / NI 43-101 technical reports as required figures. The export includes north arrow, scale bar, legend, and title block — all standard map elements required for JORC Code / NI 43-101 compliance.
