MinPET is a patented new technology under development at the University of Johannesburg, providing the first ever high-throughput 3D imaging of locked diamonds within kimberlite rocks up to 15cm in diameter.
All aspects of the technology have been demonstrated in the laboratory.
MinPET is a novel combination of two reliable, widely deployed and actively researched technologies:
MinPET is financially feasible in some mines purely as a method to prevent the breakage of large stones mines during crushing.
If MinPET is configured to find all diamonds, it will eliminate the need to process 99% of incoming material, promising massive cost, environmental and land savings.
MinPET can be deployed in other roles, including auditing diamond content in ore streams, re-processing tailings and drill core analysis in prospecting.
Long term diamond price trends are promising.

MinPET repurposes established, reliable technology in an novel setting. This technology is constantly improving, making MinPET an ever more attractive option.
MinPET has significant advantages in activation efficiency and image creation over previous attempts to image diamonds.
MinPET is backed by compelling laboratory results, theoretical work and computer simulation.
CERN connections: We have leveraged our CERN partnership to create cutting edge, low cost PET detector electronics that reliably find diamond simulants.
MinPET is safe to operate, and does not measurably damage diamonds.
