Assessment Reports
Last updated on March 18, 2024
The BC Geological Survey reviews and maintains collections of mineral and coal technical assessment reports submitted under the terms of the Mineral Tenure Act, the Coal Act, and the Regulations under these Acts.
ARIS (Assessment Report Indexing System) is the collection of technical assessment reports and data from mineral exploration and development properties across British Columbia.
Filed by the exploration and mining industry since 1947, assessment reports document geological, geophysical, geochemical, drilling, and other exploration related activities. Once approved, assessment reports are kept confidential for one-year from the date that the exploration and development work was registered. Newly public assessment reports are made available on a monthly basis.
COALFILE is the collection of assessment reports and data from coal exploration and development properties across British Columbia.
Coal assessment reports have a confidential status for three years from the date of submission. Specific types of information are kept confidential indefinitely; described in detail in Section 2 of the Regulation.
The information contained in COALFILE is stored as a relational database (Microsoft Access) and includes spatial information for boreholes, bulk samples, and trenches. All of the off-confidential coal assessment reports are downloadable in .pdf with additional digital data as .zip files where available.
View and download mineral and coal assessment reports through MapPlace 2.
