5 ECONOMY Zimbabwe is well endowed with significant quantities of MINERAL AGRICULTURAL and HUMAN resources. MINING IS A LEADER IN THE ECONOMIC DRIVERS THAT INCLUDE AGRICULTURE AND MANUFACTURING.

6 OUTLINE OF GEOLOGY INDEX of detailed geological mapping About 60-65% of the country has been mapped in detail. Each block has a 1: map & a descriptive text called Bulletin or Short Report all available at the Geological Survey Department

7 OUTLINE OF GEOLOGY

8 OUTLINE OF GEOLOGY

9 60% is Archaeanbasement Gaold Granite-gneisses enclosing volcano-sedimentary piles known as greenstone belts Greenstone belts rich in economic minerals OUTLINE OF GEOLOGY ArchaeanCraton

10 OUTLINE OF GEOLOGY Metamorphic belts surrounding craton the ArchaeanLimpopo Mobile Belt to the south the ProterozoicMagondito the northwest the ProterozoicZambezi Mobile Belt to the north and northeast All rich in economic including metamorphic minerals

11 the Proterozoic Magondi, Gaireziand Sijarira basins the Permian-Triassic- Jurassic Karoo Supergroup Cretaceous sediments Tertiary to Recent sands of the Kalahari. OUTLINE OF GEOLOGY Sedimentary Basins

12 COAL RESOURCES Large reserves in Lower Karoo of the mid Zambezi Basin the Save-Limpopo basin. Estimated resources of >12 billion tonnes (20 billion tonnes) (26.65 billion tonnes) The Hwangearea hosts large reserves of both coking and thermal coal. Despite the widespread occurrence, development and production has been around Hwangearea. (Hwange, Makomo & Galpex) There has been limited coal production from the Sengwa, Tuliand Mkwasine coalfields

13 COAL RESOURCES Known coal areas of Zimbabwe. 1 Sinamatella; 2 Western areas; 3 Hwange Colliery; 4 Entuba5 Dahlia; 6 Hankano; 7 Lubimbi; 8 Sebungu; 9 Lubu; 10 Lusulu; 11 Sessami; 12 Kaonga; 13 Bari; 14 SengwaSouth; 15 Sengwa North; 16 Nebiri; 17 Marowa; 18 Msambansovu; 19 Strange s Coal; 20 SabiValley; 21 Mkwasine; 22 Malilongwe; 23 Bendezi; 24 Chivumburu; 25 Bubye East; 26 Bubye West; 27 Singwezi; 28 Umzingwane; 29 Massabi. (now 34 locations)

14 COAL EXPLORATION 1. Geological Mapping/ Prospecting Licences/ Special Grants 2. Introduction of Exclusive Prospecting Order (EPO) on 1 st July 1947 to facilitate prospecting over large areas. 1 in by October Some discoveries through EPOs include: Lubimbicoalfield -EPO 13 Tulicoalfield -EPO 19 Bubye coalfield -EPOs 50 & 112 Sengwacoal deposit -EPO 446
