The property includes the AK6 Kimberlite pipe which is demonstrably diamond bearing. Diamonds occur as xenocrysts which have been entrained by the Kimberlite magma during its ascent to surface from depths ranging between approximately 150km and 180km. Factors influencing the grade of mineralization include the quantity of diamonds originally entrained by rising magma, the rate of ascent to surface and possible resorption of some diamond into graphite, and dilution of the primary Kimberlite magma by barren country rock material. The grade of the AK6 Kimberlite has been estimated by successive sampling programmes to produce an indicated mineral resource to a depth of 400m and an inferred mineral resource to a depth of 750m.
