1. IntroductionPhysical rock property data, systematically recorded and comparable using standard formats, isintegral to successful interpretation of subsurface geology from geophysics. This projectrepresents a foundation in building a useful database for British Columbia. This data release isthe result of a significant amount of work by Mira Geoscience and the Geological Survey ofCanada to produce a standardized, high quality dataset of nearly 900,000 data points for theprovince. A significant amount of industry data remains to be added to the database.In April 2006, CAMIRO submitted a Proposal for 'Development of a Rock Property Database forBC' to Geoscience BC. In August 2006, the Proposal was accepted after confirmation that asignificant amount of data existed to be entered into the database. Project 2006-015 started up inOctober, 2006 when Mira Geoscience was contracted by the Canadian Mining Industry ResearchOrganization (CAMIRO), for a one year project involving the assembly and organization ofphysical rock property data for the Province of British Columbia. A large amount of rockproperty data exist for BC, however this data was in various hardcopy and digital formats,archived at many locations across the country making it difficult to amalgamate. One of theobjectives of this project was to bring together all available data for BC into standard digitizedformats on a common integration platform. The Project focused on rock property data collectedby the Geological Survey of Canada related to borehole surveys from the 1990’s, mapping of BCbasins, TGI-3 program, and recent surveys in the Nechako Basin.The strategy was to compile the various rock property data for BC into “RPDS” (Rock PropertyDatabase System), a database application developed over the last 9 years by a consortium ofindustry and government agencies, and managed by Mira Geoscience. Data delivered in thisproject are in two formats: (1) summary database files on DVD to be downloadable from MapPlace and (2) files accessible from the Mira Geoscience server through the RPDS website. RPDSis an Oracle-based relational data management system, which brings together geological andgeophysical information and facilitates interpretation of rock properties and correspondinggeological description across geographic areas. This permits statistical and spatialcharacterization of the rock property environment for various ore deposit types in differentgeological settings. The significance of RPDS is that it provides a single repository for rockproperty data, as opposed to many disparate sources, thus allowing large-scale aggregation of1
