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.

For a full step-by-step guide to drill results maps, see How to Make a Drill Results Map.

Import your drill collar CSV (columns: hole ID, latitude, longitude, depth, assay)
Assign the Drillholes layer role
Import the property claims boundary as GeoJSON
Add callout labels to key holes showing hole ID and best intercept
Use Badge Label type to highlight the highest-grade holes
Configure the title with program name and date
Set the Landscape 16:9 ratio for news release figures
Export as PNG at 2× for email and PDF for the news release attachment
