The Great Dyke of Zimbabwe: Sitting on Gold!!!
![Page 5: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/5.jpg)
THE GREAT DYKEThe Great Dyke is a
mineral rich natural occurrence running from SSW to NNE in the central part of Zimbabwe for 550km,
Its width varies from 3km to 12km.
It is hosts the second largest deposit of PGMs in the world after RSA
The Dyke also hosts the largest known high grade chromite deposit in the world

GREAT DYKE
![Page 6: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/6.jpg)
GEOLOGY OF THE DYKEThe Dyke consists of 5 sub-
chambers each with a shallow synclinal structure.
Within these sub-chambers is a layer known as the Main Sulphide Zone (MSZ)
The MSZ is a 1 – 2.5m thick layer enriched in sulphide minerals. It contains economic concentrations of all six platinum metals (PGM)
![Page 7: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/7.jpg)
World Ranking
The platinum resources in the Great Dyke are second in the world only to those of the Bushveld Igneous Complex of South Africa.
The Great Dyke of Zimbabwe is unique in that the MSZ outcrops on some parts and near surface making platinum mining on the dyke a low cost production, compared to other leading platinum operations

Underground Mining Method is employed for extraction of ore.
ZIMPLATS, Mimosa and Unki employ the bord and pillar mining method is employed to extract the ore.
All have invested heavily in mining equipment that include drilling jumbos, Load Haul Dump trucks, underground dump trucks and conveyor belt systems.

BENEFICIATIONCurrently Unki and MIMOSA produce concentrates
which are transported by road to RSA for Smelting and further beneficiation
ZIMPLATS smelts its concentrates to produce converter matte, is sent to South Africa for base metal refining to recover Nickel, Copper and Cobalt and precious metal refining to recover the 6 PGMs as well as Gold and Silver.
There is need to have a Base Metal Refinery and Precious Metal Refinery in Zimbabwe…..an accepted Policy position

ZIMBABWE’S COSTS COMPETITIVENESS2013 Typical Production costs comparison: Impala platinum Mine
Mine Cost/tonne Milled ($)
Cost per PGM Oz in Matte ($)
Cost per Platinum Oz in
Matte ($)
ZIMPLATS (Zimbabwe)
55 622 1307
Marula (South Africa)
98 849 2230
The Zimbabwean PGM mines are relatively shallow (200metres VS 2km deep), low-cost operations run by a small, skilled and less militant workforce.
The industrial relations climate in Zimbabwe makes it more conducive to operate a mine in the country than in South Africa.

HOW DO WE GET WHERE WE WANT TO GO???
![Page 25: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/25.jpg)
Potential for Further Beneficiation and Value Addition in ZimbabweThe case for Base Metal and Precious Metal
refining in Zimbabwe is overwhelming, especially given the vast PGM resources in the country.
As production capacity continues to increase, the capacity of the refineries in South Africa will be saturated.
The potential employment and downstream economic benefits also favour development of beneficiation facilities in Zimbabwe.
![Page 26: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/26.jpg)
Potential for Further Beneficiation and Value Addition in Zimbabwe
For Base Metal Refining, available facilities are;Empress Nickel Refinery (RIOZIM)Makwiro (ZIMPLATS), using the mothballed BMR plant, Bindura Nickel (Mwana Africa) Alaska (ZMDC)
or construction of a new BMR.
For Precious Metals, it is necessary to construct a Precious Metal Refinery for the recovery of PGMs, Gold and Silver.
Expansion should be synchronized with power supply expansion (100MW)

CONCLUSIONSThe Great Dyke hosts the world's second
largest known PGM resources after the Bushveld complex of South Africa
The Main Sulphide Zone which hosts the PGMs and Base Metals is shallow, hence mining can be done at relatively low cost in comparison with other leading Platinum operations on the production cost curve.
The operating Mines carry out limited beneficiation stages in the country – and Government has pushed for more beneficiation and value addition
![Page 34: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/34.jpg)
CONCLUSIONSIn line with the Government's ZIMASSET
economic blueprint, it is required that beneficiation and value addition of PGMs and other minerals be carried out in the country.
Smelting, Base Metal Refining and Precious Metal Refining and further Value Addition should be undertaken within the country.
About $1-$2 billion investment is required to put up the necessary processing plants, support infrastructure and increase power generation.
![Page 35: ZIMASSET AWARENESS SEMINAR FOR MEMBERS OF THE PARLIAMENT OF ZIMBABWE 12 - 13 MARCH 2014.](https://reader034.fdocuments.in/reader034/viewer/2022052414/56649db25503460f94aa1e52/html5/thumbnails/35.jpg)
CONCLUSIONSThis could be facilitated by Government Policy
and legislation which : creates a stable and predictable investment climate provides investment incentives Promotes development of skills encourages skilled Zimbabweans living in the diaspora
to return attracts specialist skills that are in short supply in the
country promotes research and technology development
The socio-economic benefits of such investment and development include increased revenue inflows, industrialisation and employment levels.
