This dataset contains geochemical assay data collected by companies exploring in NSW. The data is sourced from a number of different exploration methods including; stream sediments, soil samples, rock chip samples and various types of drilling. Since 2000 the Department has required exploration companies to submit geochemical data digitally in standard reporting templates. Prior to this the data was submitted in hard copy reports. Data from both the digital templates and hard copy reports have been entered into an SQL database.

The Geochemistry (Whole Rock) dataset contains information about the chemistry of rocks sampled in New South Wales and held by the Geological Survey of NSW (GSNSW). The data has been captured from analyses conducted by the GSNSW and from other work including academic research & collaborative projects, mineral exploration reports and geoscientific publications. The database contains geochemical analyses on nearly 27,000 rock samples which have been collected from field work and drilling activities which date back to the nineteenth century. There are also a small number of assay & hydro-geochemical results. It is an important dataset as the whole rock analysis of rocks for major and trace elements allows classification of the lithology of a rock and provides insight into the conditions in which the rocks formed as well as their economic potential.

The Field Observations (FieldObs) database stores observations and measurements of rocks collected by the Geological Survey of NSW. Includes location information, stratigraphic unit, links to mineral occurrence and drill hole data, photo and sketch captions, structural measurements and observations, lithology and rock descriptions, sample collection information, and petrophysical measurements (magnetic susceptibility, radioelement and density).
