[en] Geofirma Engineering Ltd. (Geofirma) was retained by the Nuclear Waste Management Organization (NWMO) to complete a drilling and testing program for two deep bedrock boreholes (SB_BH01 & SB_BH02) as part of the NWMO’s Phase 2 Geoscientific Preliminary Field Investigations. The full scope of the drilling and testing program for SB_BH01 is described in the Initial Borehole Characterization Plan. Borehole SB_BH01 is located approximately 3.5 km northwest of the community of Teeswater, Ontario (see Figure 1) and was drilled to 880.84 m below ground surface (m BGS). SB_BH01 was drilled through the entire sedimentary bedrock sequence to approximately 20 m into the Precambrian basement. The purpose of this study is to provide geoscientific data that can be used to do a preliminary assessment of: 1) the quantity of organic matter present in core samples obtained from selected formations encountered by borehole SB_BH01; and 2) a preliminary assessment of the thermal maturity of the kerogen and clay mineralogy of several formations at the South Bruce Site.
