Our clients and partners say
We're so happy to be working with Stark Resources. We're impressed by their competence, experience, dedication, and their ability to think outside the box and solve problems. Very important for early stage and low-cost oriented companies like ours, operating in challenging environments.
Thomas Häggkvist
CEO Africa Resources
We acquired an updated stand-alone XRT plant and within a very short space of time recovered the 91O ct D-colour Lesotho Legend diamond at Letšeng. This must surely rank as one of the best ROIs that has ever been seen!
Clifford Elphick
Chief Executive Officer
Stark has enhanced and vastly improved our XRT sensor-based sorting and tracer testing for primary diamond recovery with bench scale test work, field testing and the full scale implementation of automatic, remote RFID tracer systems. This innovative approach provides further process assurance in real time.
