A Transect Through Gold Deposits and Prospects of the Damara Belt, Namibia
Description
The central parts of the Pan-African (580-500 Ma) Damara belt in Namibia are rapidly emerging as an important gold district. Established deposits such as the Navachab and Otjikoto mines, the recently discovered Twin Hills deposit, and numerous historically mined prospects testify to the gold endowment of the area. This has sparked a flurry of exploration work in recent years with promising early exploration results.
Gold mineralization in the high-grade metamorphic, mainly metasedimentary country rocks shows a range of styles (orogenic and quartz vein-hosted to disseminated), lithological controls (in marble units, metaturbidities or crosscutting lithological sequences), and structural positions (in structural corridors/shear zones, fold limbs, fold hinges, or outside any clear structural zones). Exposure is highly variable, and exploration targets are increasingly covered by sand and/or calcrete. All this has rendered exploration difficult, and there is to date no clear conceptual model that accounts for the different styles of mineralization and that may guide exploration.
This field trip visits and examines, over six days, the established (Navachab and Otjikoto) and developing (Twin Hills) mines of the region and some of the promising prospects that are in an early stage of exploration (Ondundo and Eureka). The trip examines open-pit operations and field exposures and, in areas of less favorable outcrop, borehole core. The aim is to contextualize the differing controls of mineralization (lithological/structural) on a deposit/prospect scale and before the regional geologic setting and evolution (first- or lower-order structures, regional distribution of rock types, P-T conditions, regional strain, etc.) of the region.
Transport will be in 4WD vehicles. Accommodation (shared) is in country hotels. All meals (breakfast, packed lunches and dinner) will be provided. Included is an excursion guidebook with a synopsis of the regional and local geology and description of individual mines and prospects that will be visited. Temperatures in late September will be cool to mild in the evenings, but hot during the day (15°/32°C) and it will be dry. Expect a high UV index. Field gear is required, but we will refrain from strenuous climbs.
About the Leaders
Emmanuel Shilongo
Koryx Copper Inc.
Emmanuel is the project manager for Koryx Copper (Haib Copper Project). He is a mineral exploration geologist with an M.Sc. in applied geology and 13 years of post-graduate experience in technical and managerial functions for mineral exploration in a range of commodities, particularly orogenic gold and copper. His expertise includes regional exploration as well as advanced exploration. Emmanuel has previously worked for Osino Resources Corp, African Pioneer PLC, and Bezant Resources PLC for the past five years as a senior exploration geologist and project manager.
Josia "PJ" Shilunga
University of Stellenbosch
Josia is a Ph.D. candidate in Earth Sciences (structural geology and economic geology) in the Department of Earth Sciences at the University of Stellenbosch in South Africa. His research combines field structural analyses with geophysical data, 3D modelling and geochemical assay data to understand deposit-scale controls of mineralization. His recent work focuses on the controls of hydrothermal fluid flow and gold mineralization in the Karibib gold district in the Central Zone of the Damara Belt of Namibia.
Jeremie Lehmann
University of Johannesburg
Jeremie currently lectures structural geology and tectonics at the University of Johannesburg. His main research interests and expertise revolve around the thermal and mechanical evolution of Archaean, Proterozoic, and Phanerozoic orogenic belts. His research combines field structural analysis with remote sensing and microstructural and petrochronological data to decipher the tectonic evolution of deeply eroded mountain belts. He has worked in the Damara Belt for 10 years.
Alexander Kisters
University of Stellenbosch
Alex is a structural geologist in the Department of Earth Sciences at the University of Stellenbosch in South Africa. Much of his work focuses on the integration of regional structural work with the controls of orogenic gold deposits, in Achaean greenstones or younger orogenic belts, throughout much of Africa. He has worked in the Damara Belt of Namibia for some 20 years, including the Navachab and recently discovered Twin Hills deposits.
