Associate: Resource Modelling Geologist

Samson Malenga


A seasoned senior geologist and mineral resource management professional with more than 22 years of consistent involvement in brown fields and Greenfields exploration, operational geology, project management and mineral resource management within different geological settings (Bushveld, Great Dyke, Greenstone Belts and Zambian Copper belt, Namibian Zn-Pb-Cu VMS deposits). Before becoming an Independent Geological Consultant in 2018, Samson worked for various business units at Anglo American Plc, Vedanta Zinc International and MSA Group within Southern Africa. He has extensive experience within different geological settings and mineral commodities (PGE, Chrome, Nickel, Copper, Gold, and Zn-Pb-Cu VMS ). Samson’s experience includes green fields and brownfields exploration of gold, base metals, and PGM, including regional generative programs for the Northern Limb of the Bushveld Complex and the Achaean Greenstone Belts in Zimbabwe. He started his career working as a mine geologist within the Achaean greenstone belt Ni-Cu deposits. In 2001, Samson was seconded to Konkola Copper Mine by Anglo American where he was involved in a structural geology and geotechnical mapping project for both Konkola’s 1 and 3 Shafts as part of the inputs into the mine design of the Konkola Deeps project.

During his 21 year career, Samson had the opportunity of leading and providing key geological inputs (geological and resource models, and technical evaluation) into major world class mining projects including the development of the Unki Platinum Mine on the Zimbabwe Great Dyke and a number of projects on the Bushveld Igneous Complex (Bokoni, Twickenham, Mogalakwena Northern Limb, Der Brochen and Amandelbult Platinum Mines). In addition, Samson has strong operational geology and mineral resource management experience in tabular and massive orebodies and he has been involved in the designing and implementation of grade control and mine value chain ore reconciliation systems for underground and open pit mines. In addition, Samson played a leading role in the success of the electronic plans systems entrenchment projects at Anglo American which ensured that the use of the digital plan systems are were embedded within the mine technical services disciplines. The project succeeded in the development of a 3D spatial environment with the integration of disparate datasets (paper plans and different application systems such as Arc GIS, CAD, Sable, Datamine, etc.

Samson held various positions within geosciences and exploration at Anglo American subsidiaries culminating in his appointment as Anglo Platinum’s Group Senior Manager: Geosciences and Exploration in 2015 responsible for the Group’s operational geology, brown and green fields’ exploration, and mineral resource management functions. As Anglo Platinum’s lead in geosciences and exploration, Samson oversaw the Group’s overall geosciences discipline health and he managed major near-mine and green fields exploration programmes including a 30km extension of the PGM-Ni-Cu bearing Platreef orebody at its world class Mogalakwena open pit mine and other major exploration programmes at Amandelbult mines, the Great Dyke and a number of green fields exploration projects. The success of all these exploration programmes was achieved through the integration of a large amount disparate geological datasets ranging from regional remote sensing, regional geophysical surveys, regional soil geochemistry, exploration drilling and mine geology resulting in effective target generation and the design of appropriate exploration follow-up work.

Samson was a Chief Geologist for 8 years at some of Anglo Platinum’s large scale mining operations including Amandelbult mine where he was responsible for mining geology and target generation and near-mine exploration for a mine lease area in excess 100km2. He worked extensively with a large amount of different geological datasets ranging from regional remote sensing, regional geophysical surveys, regional soil geochemistry, exploration drilling and mine geology. Using GIS, common database platforms and geological modelling software, Samson has extensive experience in the construction regional and lease wide 2D and 3D geological structure and resource models within multi-layered geological successions.
