Ground Conditions

As per the Geotechnical Data Report (GDR): “Based on the Physiography of Southern Ontario (1984), the surficial geology of the project site is relatively consistent, typically consisting of Late Wisconsinan Age Halton Glacial Till of silty clay to silty sand texture. Within the creek valleys, surficial alluvial deposits of gravel, sand, silt and clay are present overlying the till or bedrock, often with high moisture content and some organic content.  Ordovician shale interbedded with limestone and calcareous siltstone of the Georgian Bay Formation lies at 4 to 11m below existing ground surface.” The tunnel was designed to be within Georgian bay formation shale. An area of mixed ground conditions was encountered during the first 200m of mining. The shaft were constructed within the overburden and shale ground conditions.
