Online Workshop November 16-18, 2021
Critical minerals: From discovery to supply chain

This online workshop will address the critical minerals needed to grow low-carbon economies, emphasizing those used in battery, magnet, and photovoltaic technologies.  Presentations will consider the life cycle of critical minerals from exploration, resource availability, and mineral systems to market trends and supply chains.

Organized by the British Columbia Geological Survey, Geological Survey of Canada, Geoscience Australia, and Geological Association of Canada-Pacific Section.

Database updates

Digital Geoscience Data
The Digital Geoscience Data page is available for current versions of our regularly updated datasets. 

Assessment report-sourced surface sediment geochemical database
Development and initial data release from the Interior Plateau. British Columbia Ministry of Energy, Mines and Petroleum Resources, British Columbia Geological Survey GeoFile 2019-04, 9p., version 2020-05-15. Also available on MapPlace in the Assessment Report (ARIS) layer.

Property File
Property File has grown to more than 82,800 items, with recent additions from private collections and public release of the George Cross Newsletter. The MINFILE bibliography now links more than 9500 MINFILE records directly to Property File (EMPR PFD entries in Bibliography).

A Bedrock Map Index layer is available on MapPlace in the Geology folder. The layer displays footprints for most BCGS and GBC bedrock maps; the maptip provides a link to publication details and downloads. MapPlace now also has 1:50,000-scale NTS and 1:20,000-scale TRIM hydrographic features, road networks, and contours in the Base Maps folder.

Assessment report-sourced surface sediment geochemical (ARSSG) data are available on MapPlace as two layers. One layer shows all samples, the other shows the reports that have been digitized. Both have maptips that link to the ARSSG website where all result details can be viewed and report-specific kml downloads are available. The layers are in the ARIS – Digitized Data group under the Mineral Inventory Folder.

A new layer on MapPlace presents data from a Geoscience BC Project: Georeferencing and Data Capture of National Instrument 43-101 Reports in British Columbia: The project examined publicly available information about British Columbian minerals projects submitted to the Canadian Securities Administrators (CSA) between August 2004 and October 2019 in National Instrument 43-101 (NI 43-101) technical reports to identify and provide spatial information. Information contained in the 43-101 reports was used to update MINFILE occurrences. The spatial layer on MapPlace provides the location of the reports.

Assessment Report digital data submission

Please submit any digital data files (spreadsheets, databases, maps, grids, etc.) used or created in relation to the work described in the technical assessment report. Data can be uploaded through the ARIS Data Submission page, submitted by CD/DVD/USB when a report is filed, or e-mailed to Reports themselves must be submitted to Archives of previous assessment report data are accepted and encouraged for submission. Types of data to be submitted include:

  • Geochemical data: sample location information, sample descriptions/notes, analytical certificates (e.g. .csv, .xlsx, .accdb)
  • Geological data: station location information, station descriptions/notes, structural measurements, mapping polygons and features (e.g. .csv, .xlsx, .shp)
  • Drilling data: collar location information, azimuth/dip, depth, downhole orientation surveys, core logs, sample intervals, geotechnical measurements, analytical certificates (e.g. .csv, .xlsx, .accdb)
  • Geophysical data (ground and airborne): raw data, processed data (e.g. .gdb, .xyz, .csv, .grd)
  • Imagery data: LiDAR, orthophotos, DEMs, ASTER (e.g. .tif, .dem, other raw data files)
  • GIS Products
  • Any other raw or processed digital files used in the creation of the report

The British Columbia Geological Survey (BCGS) makes these data available for download alongside PDF files through ARIS once the confidentiality period ends. Availability of digital data enables future users to more efficiently build upon work completed in previous exploration and development programs.
