Assessment report surface sediment geochemistry

The surface sediment geochemical database makes information locked in PDF or paper copy assessment reports, such as from the Interior Plateau, more accessible.

ARIS (Assessment Report Index System) is collection of about 36,700 reports that detail results from mineral exploration and development programs. Submitted by the exploration and mining industry to comply with Mineral Tenure Act Regulations and maintain titles in good standing, the reports become an open resource after a one-year confidentiality period. Although containing a wealth of information, the assessment reports are typically submitted in a form (e.g., paper or PDF file) that make working with the data cumbersome. To address this problem, we are developing databases that contain information extracted and digitized from assessment reports, and releasing data in formats that are amenable to evaluation using geospatial and analytical software.

Assessment report-sourced surface sediment geochemical database: Development and initial data release from the Interior Plateau

J. Norris and G. Fortin

This database contains surface sediment geochemical data (e.g. soil, silt, stream sediment, and till) from the Interior Plateau, and includes location coordinates, sampling parameters and notes, laboratory information, sample preparation methods, and analytical methods. We use a streamlined process for data compilation, verification, product generation, and distribution. Containing information from about 120 assessment reports, the database includes results from more than 34,000 samples, with 1,446,000 determinations from 13 laboratories. The data released herein (BCGS_GF2019-04.zip) are provided as a GeoPackage, which can be imported directly into most GIS, and as a set of CSV files. Updates to the current surface sediment geochemical database will contain additional geochemical data. Future assessment report-sourced databases will include information from drill holes and geophysical surveys.
