About GeoGhana
A national survey, made legible
GeoGhana is the digital home of Ghana's geological record — a partnership between the Ghana Geological Survey Authority and the Minerals Commission to digitise the archive, model the endowment, and open the country's subsurface story to responsible exploration.
The mandate
Four pillars of the programme
Digitise the archive
Seventy years of survey reports, drill logs, and geophysics sit on paper and film across five archives. GeoGhana is transcribing, georeferencing, and QA/QC-certifying all of it.
Model the endowment
National prospectivity models turn the unified archive into ranked, explainable exploration targets across gold, lithium, bauxite, manganese, and copper systems.
Open the front door
A single catalog, map, and data room replaces months of archive visits — cutting exploration lead time and putting Ghana ahead of peer jurisdictions for data access.
Fund the survey
Data Room subscriptions and API licensing create a sustainable revenue line for the Geological Survey, reinvested into new acquisition and digitisation.
