METTKO was formed in 2019 by Karel Osten, a process engineer with over 25 years experience in the design, operation, commissioning, optimisation and testing of pressure hydrometallurgy projects.

 

This started with work on the Lihir project, commissioned in 1997, and the latest completed project was the Copler Sulfide Expansion Project  commisioned in 2018.
