Zimbabwe Eastern Cape
A Russian company, Great Dyke Investments, is planning to
invest USD400-million to construct a precious metals mine
and smelter as part of the Darwendale platinum deposit
project in Zimbabwe. It is expected that the combined
processing capacity of the plant and the smelter will be
up to 10Mtpa. More than USD60-million has been used
to carry out an extensive geological exploration campaign
and process-related test work to evaluate ore concentration
amenability covering a significant portion of the mining
lease area. The programme determined that the lease
area has current ore resources of around 17.6Moz of
platinum group metals (PGMs) and gold. Based on a banking
feasibility study conducted last year, available reserves
for production at the first project phase stand at 7.8Moz
of PGM and gold. The company has so far completed the
establishment of the core facilities of the industrial yard
and infrastructure to support initial mine development. Construction is proposed of a new bulk petrochemical
fuel store with ship-to-shore offloading, transfer piping,
custody metering, and numerous tanks and road
tanker loading at a new facility in the Coega Industrial
Development Zone 7 in Port Elizabeth, Eastern Cape. The
berth is in the Port of Coega and the bulk tank facility
site planned for use is within 5km of the berth. The
materials are liquids and flammable hazardous chemicals.
The Great Dyke Investments project is expected to
produce 855 000oz of PGMs on completion in the next
few years. The project deepens Russia’s interest in the
Southern African region after the signing of the platinum
memorandum of understanding with South Africa last year. The conveyance of ULP, JET, paraffin, HFO, diesel, and
LPG from the berth jetty to dedicated storage tanks
will be carried out via above-ground pipelines covering
a distance of approximately 4.8km, starting from the
berth header and ending at the inlet header at the tank
farm. The pipelines will traverse up a grade of nearly
50m. The pipelines will be designed for a maximum
pressure of 16 bar and have a maximum flowrate of
1 600m 3 /h. (HFO flowrate will be around 600m 3 /h). Provision
will be made for pipeline pigging in the common lines
following a product change. The site will have the following
infrastructure components: 2.4m-high security fence
complete with truck entry/exit gates and emergency exits;
associated lighting; and closed-circuit television (CCTV).

A proposed coal mining and power generation project
in central Botswana will develop an opencast coal mine
of 6Mtpa with a capacity to produce approximately
3Mtpa after coal washing and a mine power head power-
generating plant rated at 600MW. The proposed lease
area, incorporating the mine, stockpiles, processing
areas, power plant, maintenance area, and offices, is
expected to cover 6 000ha. It will be located between
Mabgesekwa and Tonota villages in the central district of
Botswana. Kibo Mining will acquire an 85% interest in the
Mabesekwa Coal Independent Power Project in Botswana
in an all share transaction. Kibo envisages the project as
a coal-based integrated mine-mouth power plant, with
potential for incorporation of a solar component as part
of the further studies to be conducted on the project. The Gauteng Growth and Development Agency is inviting
bids from contractors for the construction of BioPark
Phase 3 at The Innovation Hub, in Pretoria. Bids will
be evaluated in terms of the 90:10 preferential points
system in accordance with the Preferential Procurement
Policy Framework Act (PPPFA), as well as the PPPFA
Regulations that were effective from 1 April 2017.
A prefeasibility study on the coal mine has been
completed, as has a scoping study, which highlight the
power plant having a maximum capacity of 600MW (4 ×
150MW), based on a coal delivery rate of 3.2Mtpa and a
life of mine of over 30 years. Water and land-use permits
and environmental certification are in place at the project
and previous studies include a pre-feasibility study on
the coal mine and a scoping study on the power plant.
