ON PROJECT OWNERS’ DESKS Further information requested on Road K69 phase 1 upgrades Project: Client: Location: will process high-grade ore through three-stage crushing, ball milling, and a carbon-in-leach circuit. The projected initial capital cost is USD1.6-billion, including USD182-million in contingency. The Tasiast Phase One expansion had been progressing on time and on budget and was expected to reach full production in the second quarter of 2018. The Phase Two feasibility study was earlier completed in the third quarter of 2017. Wood Mackenzie is providing engineering, procurement, and construction management services to Kinross for the Phase Two expansion of the Tasiast gold mine. The award follows Wood Mackenzie’s early involvement in the project executing the feasibility study for the Phase Two expansion. The project is expected to increase mill capacity to 30 000t/d to produce an average of approximately 812 000 gold ounces a year for the first five years and is Kinross Gold’s second of a planned two-phase expansion. Wood Mackenzie’s scope of work includes engineering, procurement and construction management for the addition of a new downstream processing plant fed by milled product from the semi-autogenous grinding mill installed during the initial expansion. Commercial production for Phase Two is expected in Q3 2020. As at the beginning of November, Phase One of the expansion project was progressing well, with engineering 80% complete and the majority of procurement for long-lead packages concluded. Major earthworks have begun and substantial construction has started on the crushed and the SAG mill foundations. Major contracts for the construction of the tailings storage facility have been awarded while the TSF haul road is about 65% complete. Full commercial production at Phase One expansion is expected in the second half of 2018. Kinross had also initiated the process for the Phase Two expansion feasibility study, which is expected to have been completed in the third quarter of 2017. Road Public sector Gauteng DTA 680823 has not as yet been awarded; a site attendance register and bidders list have been requested. The project relates to the upgrading of phase 1 of Road K69 from Road R104 (Bronkhorstspruit Road) to Road K54 in Mamelodi, Gauteng. This follows a compulsory briefing session on 16 February 2018.
