Our Experience

Since its founding in 1984, GDD have achieved a number of master data management system milestones –

    • Data Management and Analysis Systems – To date, GDD have implemented over 120 Data Management Systems in around 40 organisations
    • Project Disciplines – GDD skills cover the full range of project lifecycle disciplines, from exploration, delineation, resources, production grade control, reporting and tracking systems, geotechnical and environmental to mine closure monitoring systems, and many others
    • Commodities – A broad range, including gold, coal, base metals, iron ore, phosphate and strategic metals
    • Data Management Systems Scale – From data distillation and assembly for individual consultants to multi-system data management solutions for the largest mining operations

Over the same timeframe, GDD have been involved in the development and commissioning of many large-scale technical database application systems across that spectrum.

Our qualifications, skills and experience set us apart in the technical data collection, management and analysis workspace.
