Jericho Diamond Mine Site Stabilization
Jericho is an abandoned open pit diamond mine located in Nunavut, approximately 420km northeast of Yellowknife. Outcome, in joint venture with Rowe’s Construction Ltd., was awarded the contract to mobilize all requisite heavy equipment, remote camp, and materials for the breaching three existing dams to restore previously natural water flow, grading and installing a cover over the existing tailings containment area, decommissioning above-ground storage tanks and structures, constructing an on-site lined containment facility for non-hazardous wastes, and consolidating hazardous material for off-site disposal.
Outcome created certainty for the owner by submitting a tender with a comprehensive mobilization plan which was carefully integrated with the construction plan. The regulatory approvals were quickly secured and the team overcame the structure demolition and frozen-core dam decommissioning challenges such that the project was completed within the tight six-month contract time constraint and slightly under the original tendered contract price.
