A total of 25 kimberlites have been discovered on the Amaruk property and 90 per cent of the kimberlites processed for diamonds are proven to be diamondiferous. Diamonds North continues to refine how targets are defined and to date, hundreds of anomalies still require testing. A diamond stability field more than 25 kilometres thick has been estimated below Amaruk. This is based on a calculated minimum pressure and estimated temperature of pyrope garnet grains recovered from till samples across the property. This compares favourably with the diamond stability field beneath the Lac de Gras kimberlite field and reconfirms the potential for Amaruk.
Reverse-circulation drill cuttings were logged in secure facilities at the Amaruk field camp by geoscientists. Samples were securely sealed in solid containers and have been received at Saskatchewan Research Council (SRC) in Saskatoon for processing.
