A project Risk Register has not yet been established for Collom and will be a prerequisite for completion of the Pre - Feasibility Study. The Rio Tinto Project Evaluation Guidelines provide discussion of the requirements, which includes identification of categorised business and technical risks for the project, risk reduction measures and risk owners. TS can provide additional expertise to assist in developing the Risk Register if required. As part of the process to seek approval for funding of further project development CCC will need to develop a detailed Scope of Work for the Feasibility Study phase. Rio Tinto reviews of the Collom Pre - Feasibility Study will look to see this document and comment on its adequacy. A major remaining task is the need to pull together a concise, but comprehensive overall Collom Pre - Feasibility Study report, summarising all major study components and referencing supporting documents and reports as required. Effort expended in compiling a high standard of study documentation will pay dividends in facilitating the review and approvals process as well as providing a sound reference for future work. 3 METHODOLOGY Paul Tooth (TS Brisbane) and Mike Whateley (TS Bristol) visited Colowyo during the week of 11 to 15 October 2004 to review the Collom study work in relation to Rio Tinto Technical Evaluation and Project Evaluation Guidelines, as well as generally accepted technical good practice within Rio Tinto coal operations. The focus of this review was the overall project development strategy, resource assessment and mine planning. The review entailed site inspections of Collom and current CCC mining areas as well as discussion with relevant CCC management and technical staff as well as external geological contractors /consultants. Key documents reviewed included; • Douglas Phase 2 Draft Report, KEC, July 2004 • Collom Pit Ancillary Facilities (Pre - Feasibility Study), Mine and Mill Engineering, July 2003 • Pre - Feasibility Study of In Pit Crushing and Conveying and Road Design, ThyssenKrupp Robins, July 2003 • Pre - Feasibility Study of CCC Mine Expansion, ESC (Electrical Systems Consultants), July 2003 Additionally a number of plans and electronic spreadsheet files were provided by CCC. David Bailey (TS Salt Lake City) and Zip Zavodni (TS Salt Lake City) have previously reviewed infrastructure and geotechnical aspects of the Collom project. Health, Safety, Environment and Community aspects of the Collom project have not been reviewed by TS at this time. RIO TINTO TS Ref: DRAFT Version: 1 14 Technical seiwiA-s
