Turning Technical Data Into Decisions You Can Trust

Practical technical data management, data solutions, consulting and training for people working with geological and mining data. Since 1984, GDD has helped teams bring order, confidence and clarity to their technical data, so they can spend less time untangling information and more time using it well.

What We Help You Do

Your technical data is one of your most valuable project assets. GDD helps you turn fragmented files, legacy datasets, field records, images, documents and database tables into reliable master technical datasets that support analysis, reporting, compliance and decision-making across the mining life cycle.

• Collect data through practical field, import and capture workflows.
• Manage data with validation, standards, governance and provenance.
• Analyse data through accessible, auditable datasets ready for reporting, modelling and decision-making.

GDD’s Data Philosophy

At GDD, we believe good decisions start with good data. That means data should not be hidden in hard-to-follow processes or scattered across disconnected files. Our approach uses explicitly modelled data: visible, well-structured and unambiguous datasets that people can understand, validate, audit and use with confidence.

• Master Working Technical Data: the single point of truth used for analysis, modelling, reporting and decisions.
• Master Source Technical Data: the original, complete and unaltered data retained for auditability and context.
• Linked supporting evidence: images, documents, maps, certificates, reports and metadata connected directly to the records they support.
• AI-ready foundations: AI and advanced analytics increase the need for complete, validated and auditable master technical data.

In plain terms: collect it properly, keep it clearly organised, know where it came from, and make it easy for the right people to use.

Data Management Solutions

GDD’s database application suite has grown from years of solving real technical data problems. It is built for teams that need practical tools, clear workflows and connected information rather than another collection of isolated files and spreadsheets.

• gPick applications: integrated technical database systems for surface exploration, drilling, grade control, production reporting, hydrology, environmental data, resource modelling and field collection.
• gNeric platform: reusable database functions, metadata-driven forms, validation, querying, reporting, linked objects, user configuration and administration tools.
• geoUte utilities: practical tools for file cataloguing, data preview and assembly, image processing, validation, comparison, reporting and document assembly.

Experience That Keeps Projects Moving

Hands-On Training for Confident Data Stewards

GDD provides practical, site-based or off-site training designed to help your people become confident stewards of their own technical data. We keep the training grounded in real resource-sector examples, including rocks, drill holes, assays, surveys, production data and the systems your team actually uses.

Community: GSAQ Roxette Rock and Mineral Sets

GDD is proud to support the GSAQ Roxette Project, a community-service initiative that provides integrated rock and mineral teaching sets to schools and educational institutions. It is a practical, volunteer-powered project that helps students pick up, compare and understand real geological specimens.
