29 Codelco Chuquicamata Project: Chuquicamata Mine, Chile. Scope: Investigated the possibility of increasing pit slope angles as the pit approached its planned closure. The slope steepening was understood to raise the net present value of the mine, but also an increase in the likelihood of slope failures. Outcome: Completed quantitative evaluation to define the risks in terms of safety and economics, quantifying risk levels for different slope configurations and comparing results against industry norms. The study provided management with the appropriate basis for decisions about slope steepening. S TX Corporation Project: Surat Basin coal asset due diligence, Queensland, Australia. Scope: SRK, in conjunction with PricewaterhouseCoopers performed technical and commercial due diligence on a defined set of Surat Basin coal assets for a proposed purchase. Outcome: A risk investigation was performed on each technical and commercial element of the due diligence study for which SRK had responsibility . The results were collated into an aggregated risk register and included in the report. Indian Nor thern Af fair s Canada Project: Development of enterprise risk system for closed mines. Scope: Indian Northern Affairs Canada manages dozens of closed mines in the Canadian north. W e helped the Contaminated Sites Program develop an enterprise risk assessment process, including risk matrices, consequence-severity tables and action requirements. Outcome: The risk assessment system is now an integral part of INAC’ s project management process, with annually updated risk registers being used to prioritise cost control as well as environmental, social, and health and safety improvements. Ri ver sdale Mining Project: Benga Mine, T ete, Mozambique. Scope: Risk management of a bankable feasibility study (BFS) technical and commercial investigation into the greenfield establishment of a 5Mtpa open-pit mine and associated infrastructure. Outcome: A draft aggregate risk register was collated using the results from a risk investigation which was completed for each BFS element. The resultant risk register is to be included in the BFS report by the client, and the risk knowledge applied in the project approval process. Identified risk controls are to be included in the next phase of project development. Freshwater supply dam decommissioned to mitigate failure risks, Faro Mine, Y ukon. The project included engineered features (i.e. meanders, pools, riffes) specifcally designed to create fsh habitat within and upstream of the dam breach
