Observations on till samples, together with glacial striation measurements from outcrops, suggest a narrowing down of the search area for the source of the kimberlite boulders previously discovered to the south of the Lahtojoki diamond deposit. Results from the analysis at the Geological Survey of Finland Mintec Laboratory facility of twenty five 60kg till samples recovered south of the Lahtojoki diamond deposit, together with glacial striation measurements from outcrops in the Lahtojoki south exploration permit licence area, indicate an alternative glacial trend direction to the main regional glacial trend in the area of 335 degrees.
