The Office National des Hydrocarbures et des Mines (ONHYM) is a central institution for investors studying mineral exploration opportunities in Morocco. Its mining portal presents the country’s mineral potential, exploration projects, licensing information and partnership opportunities.
What ONHYM does in mining exploration
ONHYM develops and evaluates mining projects, compiles and interprets geological information, conducts exploration and promotes selected opportunities to partners. Its work can include geological mapping, geochemistry, geophysics, drilling and project-scale interpretation.
Annual reports show a model that combines ONHYM-led projects with partnership projects. For investors, the practical implication is that some opportunities may be promoted through structured collaboration, while others may arise through private permit transactions or independent applications under the mining framework.
How to evaluate an ONHYM opportunity
Understand the exploration stage
A regional anomaly, a mapped occurrence, a drill target and a defined resource are fundamentally different stages. Investors should identify exactly what work has been completed and what evidence remains to be generated.
Review the underlying datasets
Ask for the map scale, sampling protocols, analytical methods, QA/QC, geophysical specifications, drilling logs, density assumptions and interpretation history. A concise project presentation is useful, but an investment decision requires the underlying evidence.
Define the partnership decision
Clarify the proposed work program, funding expectations, project governance, data access, reporting, decision gates and exit conditions. Commercial and legal terms should be reviewed by qualified advisers.
Where a local exploration partner adds value
A Morocco-based geological team can help an international investor review the project context, organise a field visit, inspect outcrop and historical workings, assess data quality, translate technical materials and define an independent validation program.
Evaluating an ONHYM or private exploration opportunity?
Geo Ore Deposits can support technical review, GIS compilation, field verification and a decision-focused exploration scope.
