Our portfolio of organic development projects offers the benefts of established infrastructure and reduced execution risk given familiar permitting and operating jurisdictions. 2018 was an important year at our projects, and we look forward to achieving a number of key milestones in 2019.
At Tasiast, we completed and successfully commissioned our Phase One expansion project. The impressive ramp up and smooth transfer of this large and complex project highlighted the strength of our Project and Operations teams. By the fourth quarter, throughput was averaging over 14,000 tonnes per day, approximately 20% above the nameplate capacity of the Phase One design.
The Project team is incorporating this better-than-expected performance into its evaluation of alternatives to further increase throughput, with the aim of lowering capital costs while preserving Tasiast’s overall value proposition. The Phase Two expansion remains a viable option, and considerations for next steps include: alternative throughput approaches; capital priorities across the Company’s portfolio; ongoing discussions with the Government of Mauritania; and, acceptable project financing terms. We made good progress during the year advancing project financing for Tasiast, with mandate letters signed with the International Finance Corporation, a member of the World Bank Group, and Export Development Canada, as well as expressions of interest from two commercial banks.
The Phase W project at Round Mountain is well advanced with initial low-grade ore encountered ahead of schedule. Construction of mine infrastructure, new leach pad, and vertical carbon-in-column (VCIC) plant are all on schedule, and we expect to start commissioning the process circuit in the second quarter of 2019.
The Vantage Complex project at Bald Mountain, which includes a new heap leach pad, new VCIC plant, and support infrastructure, is proceeding well. The processing circuit is on track to begin commissioning by the end of the first quarter of 2019.
At the Gilmore project at Fort Knox, construction is expected to ramp up in the spring and continue through 2020. Stripping is expected to commence in the third quarter of 2019. The project is on schedule to begin stacking ore in late 2020.
In Chile, we acquired the remaining 50% in the Phase 7 deposit for the La Coipa Restart project and expect to complete a project feasibility study in the third quarter. We also expect to complete a scoping study for the Lobo-Marte project in the first quarter.
