Qotho Minerals - A31

 

Qotho Minerals was established in 2013 with the specific goal to design, implement and operate Proficiency Testing Schemes (PTS), and manufacture and certify Reference Materials for the Minerals Industry, globally.

Qotho has expanded to the point where it currently operates 13 schemes, containing 35 samples in total, 6 times per annum. Participation in our schemes affords each laboratory the unique opportunity to assess the accuracy and comparability of their results with peer laboratories over a given period.
