Sampling and Ore and Rock Properties Modification in Kevitsa Mine

The first sample collection for ITERAMS WP1 and WP2 was done in July 2017. After the first sample series were tested in Leoben and Oulu Universities, and first results were received during winter and spring 2017-2018, a new campaign was planned and decided.

This time, the Team planned and executed sample collection from the tailings pond and from one low grade / side rock blast bench. ITERAMS Team had explained to Kevitsa mine, which types of samples were targeted (including amphiboles and diopside). From the tailings pond samples were collected from four different location based on historical data available, and from the blast bench (four samples) based on mineralogical map which was made by Sini-Maria Kokko. Sample volumes were this time little bigger (all samples more than 25kg).
