Deasan Sand and Gravel Pit (Old Fort Landslide)

On Sept. 30, 2018, a landslide occurred above Old Fort Road near Fort St. John. There is a gravel mine located just above the slide that has been periodically operated since the 1980’s. 

The Chief Inspector of Mines conducted an investigation pursuant to Section 7 of the Mines Act. The investigation report summarizes the 2018 Old Fort Slide chronology, the history and development of the Deasan site, and the Mines Act permitting process for the gravel pit; provides an overview of findings from preliminary reports completed on the 2018 Old Fort Slide; and provides conclusions relevant to Deasan, to industry and to government that are intended to aid in mitigating risks associated with slope instability at the Deasan pit should mining resume there and to reduce the risk of a similar event occurring on other mine sites.  The scope of the investigation and reporting are focused on the permitted mine site.
