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.

Field Trip to the Freda Rebecca Gold Mine - Saturday 16th July

Sat, 16/07/2016

Field Trip to the Freda Rebecca Gold Mine - Saturday 16th July
Meet at 8am at the Entrance Gate ( we expect to finish around 1pm )
Bring your own underground PPE.

PLEASE NOTE: The number of people who can attend this field trip is restricted and only the first 20 who register will be able to proceed.
Book your place by sending an email back to the GSZ on this email address.

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

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.

27th Colloquium of African Geology

Sun, 22/07/2018

On behalf of the 27th Colloquium of African Geology (27 CAG) and 17th Conference of the Geological Society of Africa (GSAf17), we would like to extend a warm welcome and invite you to join us at the University of Aveiro, Aveiro, Portugal, for the CAG27. The Colloquium of African Geology (CAG) is a major biennial meeting organized under the auspices of the Geological Society of Africa (GSAf).

Senior and early-career earth scientists from organizations, associations, mining companies, civil societies, politics, and media will be welcome from all over the world especially but not limited to career scientists from African Countries and also to other colleagues that . These representatives will be from different countries and will also be active at the national level. The participation of these individuals from different sectors and countries will enhance international collaborations and increase the involvement of the international community.

Known as the “Venice of Portugal”, Aveiro is surrounded by salt-flats, beaches and lagoons, and dominated by the Central Canal running through town. Once a big sea port, Aveiro lies in a region of mountains cut by valleys and fertile lagoon plains.

The conference venue is the campus of Aveiro University, near the Aveiro city center. The conference is organized together by the Aveiro University and Geological Society of Africa (GSAf).

We believe that your presence and active participation will guarantee the success of the conference as it is a unique opportunity to share knowledge with colleagues from all over the world.

We look forward to welcome you to Aveiro in 2018!

At 5pm on the 19th of October in the Kramers Room, Dr Maideyi Meck will talk on 'African Mineral And Energy Resources Classification And Management System (AMREC) And Panafrican Reporting Code (PARC)'

The African Union Commission has recommended that a system for management of Africa’s mineral and energy resources i.e. African Mineral and Energy Resources Classification and Management System be put in place. A working group was put in place to come up with a classification system and a reporting code. Starting with the existing classifications and reporting codes the working group has come up with (UNFC-AMREC) and PARC. The two will be presented to the AU ministrial committee before year end. Dr Meck in her capacity as Secretary General of Geological society of Africa was invited by the working group as an observer in July to attend the session which was discussing the classification and reporting code at the 27th Colloquim on African Geology. In this presentation she will give an update of the classification and reporting code to date. Participants are free to put in their contributions. Dr Meck will be able to forward them to the working group as she will also attend the session that will be finalizing the classification and reporting code in November before it is presented to the African ministers
