With the rapidly expanding coal industry in Queensland, in June 2014 Mitra SK acquired Preplab Testing Services Pty Ltd – a NATA accredited coal laboratory group having physical testing and laboratory services already established in Rockhampton and Gladstone in Central Queensland.

Preplab Testing Services Pty Ltd brought to Mitra SK 25 years of experience in the Queensland coal industry, in the fields of bore core preparation and quality analysis as well as Coal Preparation Plant quality control and production quality monitoring. Preplab Testing Services Pty Ltd became a wholly owned subsidiary of the Mitra SK Group and in January 2019, Preplab Testing Services Pty Ltd became Mitra PTS Pty Ltd – a Coal testing laboratory group with plans to expand into the Australian Base Metal, Bauxite and Gold industries.
