The results indicate that a diamondiferous kimberlite pipe or dyke is likely to exist in the Riihivaara area.
The till sampling program at Riihivaara resulted in the recovery of 12 garnet indicator minerals, comprising three G10’s, five G9’s, one G4, one G3 and two G1’s.
Six of the positive results, including the G4 pyroxenitic garnet occurred within a single till sample, and the adjacent sample had two positive results, including the eclogitic G3 garnet.
These garnets and other mantle-derived minerals are used to locate kimberlites and are referred to as kimberlite indicator minerals, the company said.
