Data Management
Z Star experience has shown that robust management and storage of data is
essential for accurate mineral resource estimation.
Typically mineral resource and reserve information encompasses a vast array of complex data types which all require consideration in terms of optimal data handling and, importantly, amalgamation into a combined, user-friendly database environment.
It is critical that database information is independently verified against original hardcopy documents, a service that Z Star routinely provides to clients. Z Star provide robust assurance of mineral resource estimates and conduct risk analyses on existing mines or new projects. The company will undertake due diligence audits, resource performance analysis and provide governance advice.
Mineral resource database validation
In particular, mineral resource databases house the key information required for reporting purposes, i.e. the data required for routine public disclosure of mineral resource and reserve figures. It is essential that this data is accurate and well managed. Z Star have the expertise to check and validate your mineral resource data to negate errors and provide assurance.
Exploratory Data Analysis (EDA)
Statistical and geostatistical analysis of variable data must be undertaken prior to mineral resource estimation. This is critical in terms of defining an estimation methodology and ensuring that the estimation dataset is valid. The EDA includes a correlation with the geological model and identifies potential anomalies that must be discussed in detail with the project geologists to “iron out” potential problems.
Database design
Z Star offer expert advice on optimal database design for storing raw or manipulated data. Correct design of the database allows for rapid and efficient access by users.
