Details

Background

The Detour Lake Gold Mine Project is located north of Cochrane, ON and is the flagship project of Detour Lake Gold Corporation. The mine is expected to go into gold production in 2013.

TBT Engineering’s Role

TBT Engineering has been retained by Chartrand Equipment to provide Quality Control (QC) testing of soil and aggregates intended for use during construction of earthworks associated with the Tailings Management Area.

Mobile Laboratory

A fully equipped mobile aggregates laboratory has been operating onsite for over a year in order to expedited testing and reporting. Some of the equipment located within the mobile laboratory includes:

  • 22 Kg capacity electronic balance (0.1gram accuracy)
  • Sample splitting equipment
  • 200 mm diameter brass sieve set
  • 8 inch diameter brass sieve set
  • 0.75 mm wash sieve
  • Sample heating and drying oven
  • Gilson Sieve Shaker complete with screens
  • Riprap sieves or templates
  • Nuclear density gauges

Quality Control Procedures

TBT Engineering is undertaking onsite QC testing of construction soils and aggregates in accordance with relevant project specifications and ASTM procedures at required frequencies for determining product quality and acceptance during production and placement operations.

Primary on-site testing has encompassed gradation, moisture-density testing, and field density (compaction) testing. Aggregate samples are being taken in accordance with LS 625. Compaction testing is being undertaken in accordance with ASTM D6938-10, In-Place Density and Water Content of Soil by Nuclear Methods.

In addition to on site testing, samples are being taken at appropriate frequencies and being shipped to our Thunder Bay laboratory for physical quality testing.

TBT Engineering is maintaining up-to-date diaries, databases, and reports for all material produced and samples taken throughout the duration of material production and placement.

Certifications

TBT Engineering is CSA, CCIL and CNSC certified for construction material testing.
