PMC started out as a company providing bulk diamond sampling services and diamond process consulting services in 2016. Before PMC, similar services were provided by the same core team as part of Gemcore Sampling and before that De Beers Exploration Services since 2000.
PMC has more than 25 years of experience and has been involved in more than fifty projects in South Africa, Botswana, Lesotho, Angola, Sierra Leone and Canada to companies such as Rio Tinto, BHP Billiton, Petra Diamonds, De Beers, Firestone Diamonds, Mothae Diamonds, Ekapa Mining, Kareevlei Mining and other smaller companies.
Due to the nature of bulk diamond sampling, i.e. multidisciplinary services in remote areas, PMC is also competent in the operations and maintenance of small and medium scale treatment plants, the design and fabrication of small and medium size treatment plants, quality management systems and process/efficiency parameter recording, capturing, processing and reporting.
In 2023 PMC obtained a caustic fusion laboratory (bought the previous partner out) and a MiDA (Micro Diamond Analysis) laboratory from an established Geological Services Company. This acquisition enabled PMC to provide the complete microdiamond analysis service. PMC is now able to reduce samples through caustic fusion to recover micro diamonds down to 75um with 60X Microscopes, weighing the micro diamonds with an ultra-micro balance and characterising the micro diamonds. PMC completed more than 20 MiDA projects, achieving the quality standard of 90% recovery of all tracers.
In 2023 PMC obtained ISO9001-2015 Quality Management Certification for “Diamond Resource Evaluation Services to the Mining Industry”.
