Don't underestimate the importance of the Permits approved for South Lahtojoki, read this: Kimberlite boulders have been found in the permit area. These boulders are semi-surface kimberlites crystallized from subvolcanic intrusive rocks. The Lahtojoki deposit, on the other hand, consists of tuffitic kimberlites, so the boulders in the Lahtojoki South license area cannot originate from the Lahtojoki deposit.
The company has taken bed moraine samples from twenty-five research mounds in the license area. About 60 kg of sample was collected from each. The purpose was to find more kimberlite boulders and to deduce the direction of the glacier. During this mounting program, the furrows of the glacier were also studied from rock outcrops in the permit area. This program showed an alternative glacier flow direction found in the area compared to the main regional glacier flow direction, which makes it easier to locate the source of the boulders.The company has also studied the kimberlites of the area in more detail by producing and studying thin sulfur. Thin-hole studies showed that the kimberlite boulders contain several violet-red peridotite garnets (G9/G10 Cr-Pyrope) and orange eclogitic garnets, as well as several larger ilmenite grains. In addition, GTK analyzed four fine sands with Electron Probe Micro Analyzer (“EMPA”) and Scanning Electron Microscope (“SEM”) methods. These analyzes showed that the kimberlites are similar to other diamondbearing kimberlites in the Kuopio-Kaavi region. The analyzes also showed that the ilmenite composition of the samples is
similar to the Lahtojoki deposit, but they may contain even more diamonds.
