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.

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.
The estimated 30-month R440-million for the east road upgrade
includes a northbound dual carriageway, two bridges over the
railway line, cycle and pedestrian paths, as well as taxi lay-bys.
The Gauteng government has invested almost half a billion rand
to upgrade the busy K54 Tsamaya Road in Mamelodi. Other
works include resurfacing the section leading to the N4 freeway,
application of road markings, and the installation of traffic signals.
Upon completion, the road will serve as an important link
between Mamelodi and the N4 freeway and act as an alternative
to Moloto Road, in addition to improving road safety and acting
as a catalyst for socio-economic development in Mamelodi and
surrounding areas. The project will see the main contractor
subcontracti ng work to local small, medium, and micro-sized
enterprises.
