Original source description
Nguvu Mining is hiring a senior specialist to look after the geological data behind the Nzema Gold Mine in Ghana's Western Region, which its subsidiary Adamus Resources operates. Every drillhole, sample, assay result and survey pick that the geology team produces ends up in a database, and the mine's grade control, resource estimates and mine plans all draw on it. This person keeps that data correct, secure and easy to use, and runs the mine's mapping (GIS) systems alongside it.
The post sits in the Geology department and reports to the Adamus Resources Geology Manager. It is a full-time, site-based job covering the Nzema operation and its exploration projects. At first the work rotates between three group sites: Nzema, the Konongo mine in Ghana and the Poura gold mine in Burkina Faso. After that, the base is Nzema under the site's normal roster, with occasional trips to other operations when needed.
The work
The core platform is acQuire running on Microsoft SQL Server. You would administer it end to end: user access and security, backups and upgrades with IT, data dictionaries and coding rules, and the SQL queries and views that the geologists use for reports. Data coming in from drilling, logging, sampling, the laboratory, QAQC, surveys and geotechnical work has to be checked and reconciled before it is released for modelling or resource estimation, and every change needs an audit trail. JORC reporting requirements apply to that assurance work.
On the GIS side you would keep the spatial records in order: geological maps, drillhole positions, exploration targets, pit and lease boundaries, licences and infrastructure. That means one coordinate system and naming standard throughout, version control, links into the modelling and mine planning software, and standard map templates for reports and management reviews.
A large part of the job is teaching. The mine wants its own geology staff able to handle routine database and GIS tasks without depending on one expert, so you would write procedures and manuals, train and assess site personnel, and set up succession arrangements. You would also look for improvements such as automated validation and reporting, move old data into the current system, keep a log of issues and fixes, and work with laboratories, consultants and software vendors.
Who should apply
A degree or diploma in a relevant subject: geology or geological engineering, GIS or geoinformatics, computer science or information technology, or a closely related field.
Seven to ten years of geological database management or administration in mining or mineral exploration.
Hands-on acQuire administration, solid SQL Server and SQL skills, and a good grasp of relational database design and data validation.
Experience handling exploration, grade control, logging, assay and QAQC data, and with GIS software such as ArcGIS Pro or QGIS.
A record of setting up, migrating and troubleshooting geological databases, writing data procedures and training other staff.
An understanding of the data that Mineral Resource estimation depends on.
Holding a certification in acQuire, in SQL Server or in a GIS platform counts strongly in your favour. Other pluses: managing databases across several mines or projects, implementing or upgrading acQuire, Python, Power BI or advanced SQL scripting, enterprise GIS databases, historical data migration, JORC familiarity and experience at West African operations. Careful attention to detail, independent working and the ability to coach others all matter in this role.
