Magmatic PGE-Cr-V-Ni-Cu ore deposits: global distribution and petrogenesis

At 5pm at the Geology Department at the University of Zimbabwe

Talk - Martin Straßburger - "Pre-colonial Gold Mining in Zimbabwe: A mining archaeological view"
Fri, 26/09/2014

5pm at the Geology Department at University of Zimbabwe

"Ancient gold mining has been associated with Zimbabwe since the beginning of recorded history in southern Africa" (Huffman 1974). Open cuts, underground workings on the quartz reefs and especially features connected to the exploitation of secondary deposits give evidence of vigorous mining activities. In Zimbabwe's Nyanga mountains countless surface features comprising terraces for deflection and distribution of water, pits and processing areas.

The country’s large number of early gold-workings is unique and forms an unparalleled mining archaeological legacy, which deserves further research. Especially, when seen in a wider archaeological and historical context it becomes clear, that it is not only of national importance but goes far beyond.  Therefore, the mining features deserve a full and thorough mining archaeological research aiming apart from their chronology at the cultural, socio-economic, environmental and landscape history.

A Short Note

All the information presented here is found on the Asa Resource Group official website; http://www.asaukplc.com/

The gold mine is situated near the town of Bindura, approximately 90km north-east of Harare, Zimbabwe – Figure 1

 Inline image 1

Geology

FRGM lies on the central axis of the synclinal Mazowe-Bindura Greenstone belt. The geology of the area around FRGM is characterised by the Shamvaian sediments, diorite and granodiorite.

The FRGM orebodies are largely hosted by the Prince of Wales diorite and the Bindura granodiorite. The mineralisation is hosted within two major shear envelopes. Individual shears are variable in width and these two systems merge to the south west at depth flattening at around 850m elevation and extending into the metasediments. The shear system is characterised by a set of anastomosing shears separated by relatively underformed rock units.

Background

Historical exploration and production – back to 1912

The Freda oxide and the Freda and Rebecca sulphide gold deposits are part of the more recent (modern) discoveries in Zimbabwe – 1987

Cluff Resources were the first to develop 2 open pits – mining oxides at Freda and sulphides at Rebecca.

In 1996, Ashanti Goldfields Zimbabwe acquired the mine in 1996 when underground operation at Rebecca were developed.

In 1998, the Freda-Rebecca became a fully underground gold mine

In 2007, the mine was put on care and maintenance until 2009 when mining restarted.
