Mining
TECT, an abbreviation of “Tectonic”, has its roots in the opencast mining industry
Over two decades ago, TECT undertook detailed structural mapping and 3D Geomodelling at Rössing Uranium Mine in Namibia and De Beers’ Venetia Mine in South Africa. Since then, TECT’s philosophy of careful, high-resolution mapping, structural interpretation, data custodianship and advanced, best-practice 3D Geomodelling, has resulted in over 100 fully-constrained 3D models of major structures, country rock and orebody geometries, alteration zones, fracture domains and bedding or foliation domains. Our business was initially focussed on Africa and the Middle East, but we now operate in South America, North America, Australasia, Central Asia and Europe, from our offices in South Africa and LATAM.
Each TECT Geoscientist takes full custodianship of a project, from field mapping to 3D modelling and presentation of the model and its associated report
TECT incorporates validated data from every department at each operation, so that our fully-constrained 3D models may be used for pit design, mineral resource modelling, hydrogeological studies and mining simulations across a variety of platforms
Advanced 3D modelling in structurally-complex settings is our speciality
In particular, shear zone-hosted gold mineralization, orogenic and Birimian-type mineralization, polygenetic base metal mineralization, copper and gold in IOCG-type deposits, high- and low-sulfidation porphyry and epithermal deposits, and rare earth element mineralization have been an important part of our most recent work.
3D stress-strain analysis
We have pioneered the development of tertiary products, including apparent dip analysis, to resolve the angular relationships between planes of anisotropy and pit design surfaces. Furthermore, we have also developed scripts for extracting 3D representative form surfaces of planes of anisotropy, interpolated from a combination of mapping, oriented core logging and O/ATV data. These products form important components of simulated 3D stress-strain analysis and the determination of potential failure modes
