North Arrow Minerals Inc. [NAR-TSXV; NHAWF-OTC] has identified a compelling drill target at the head of a regional kimberlite indicator mineral train at its 100%-owned Loki diamond project in the Lac de Gras region of Northwest Territories. The target has been identified from initial results of a recently completed ground geophysics program that included gravity surveys of the north Loki area as well as kimberlite EG05.
The north Loki survey has outlined a new target at the up-ice termination of a prominent and unsourced regional kimberlite indicator mineral anomaly that forms part of what has historically been known as the South Coppermine train. Initial results from the gravity survey define an elongate gravity low anomaly, over 400 metres long and 100 metres wide. The anomaly has a maximum amplitude of approximately 0.35 milligal, which is similar in strength to gravity anomalies associated with some of the known kimberlites in the region, including EG05.
Ken Armstrong, president and ceo, said: “The size of this newly defined gravity anomaly, combined with its location with respect to the regional kimberlite indicator mineral train, make it a compelling drill target. Past drilling has tested other targets in the area, but not the anomaly itself. North Arrow is actively looking at potential timing and logistics of drilling the target this spring to test for a kimberlite bedrock source.”
The Loki Project is located approximately 40 km west, and 35 km southwest of the Diavik and Ekati diamond mines, respectively, and immediately west of North Arrow’s LDG joint venture diamond project with Arctic Canadian Diamond Company. Five kimberlites have been discovered to date within the project area, all of which have been confirmed as diamond-bearing. The 2020 and 2021 geophysical surveys have been supported, in part, by a grant from the Northwest Territories mining incentive program.
