Orogenic gold-antimony mineralisation within the structurally-complex Murchison Greenstone Belt, South Africa: New insights into regional- to deposit-scale structural controls of orebody development derived from integrated structural mapping and 3D modelling Tect was approached in early 2020 by Stibium Mining to conduct a thorough review of the structural geology and gold-antimony mineralisation at Mopani Mine, including […]

Lubambe Extension Project

project lubambe mine fi

Underground structural mapping and 3D implicit geomodelling Lubambe Mine is situated in the Cu-Co endowed Zambian Copperbelt. Mining focusses on the Ore Shale Formation, which is a thin, but laterally-continuous package that locally hosts high-grade mineralization. The Ore Shale, which forms part of the well-documented Lower Roan Sub-Group and encompassing Katanga Supergroup, regionally outcrops along […]

3D Modelling for Kumba Iron Ore’s New Kolomela Mine Kolomela Mine, previously the Sishen South Project, has proven to contain numerous economic prospects over the last decade. Tect’s involvement at Kolemela began in 2011, when we were contracted to map, structurally analyze and 3D model the Leeuwfontein and Kapstevel North prospects. Tect’s work at Kolomela […]

Jwaneng Mine

Resolving fault networks and variable bedding dips in an extensional sedimentary setting The Geotechnical and Geology Departments on Debswana’s Jwaneng Mine contacted Tect in 2012. Ongoing mining had exposed a series of structures and intrusions, including dolerite dykes/sills and syenite sills, within the mine’s highwalls. The geometry of these intrusions interacted unfavorably with the fault […]
