North Arrow’s diamond exploration programs are conducted under the direction of President and CEO, Ken Armstrong, P.Geo., a Qualified Person under NI 43-101. Mr. Armstrong has reviewed and approved all information posted on this page that is of a scientific or technical nature.


Location: Lac de Gras, Northwest Territories
Size: 8,607 hectares
Ownership: 100%
Stage: Ground geophysics and drilling.
Closest Infrastructure:  30 km southwest, and 24 km west of the Ekati and Diavik diamond mines



The property consists of two claim blocks, Loki South and Loki East, located in the Lac de Gras region to the southwest of the Diavik and Ekati diamond mines. The Loki East claims are contiguous to the south and east of the diamondiferous Monument kimberlite cluster and to the west of North Arrow’s LDG property. Loki East hosts a number of prospective exploration targets as well as five known kimberlites: EG01N, EG01S, EG02, EG05 and EG130.  

At the beginning of March 2018, North Arrow commenced an approximately 1,000 m drill program testing EG-05 as well as other priority targets. On April 5th intersections of the EG-05 kimberlite were announced along with the discovery of a new kimberlite at target 465.  Kimberlite 465 is located in close proximity to the Monument Cluster of kimberlite pipes. It was initially tested with a south oriented drill hole (18-465-01) but did not intersect anything that explained the magnetic anomaly.  A second drill hole (18-465-02), positioned approximately 30m to the west, was drilled from south to north and encountered a 20.85m interval of black to olive green kimberlite with up to and locally exceeding 10% country rock (granite) dilution. The kimberlite is generally altered and kimberlite indicator minerals including altered olivine and rare garnet have been observed. Orientation of the two drill holes suggests 465 may dip steeply to the south.  

Detailed logging of the kimberlite intervals from 465 and EG05 will be conducted including sampling for kimberlite indicator minerals and microdiamonds. Additional drilling is required to evaluate the size, orientation, and internal geology of the 465 and EG05 kimberlites, and the Loki Project also hosts a number of untested drill targets having good kimberlite indicator mineral support. Planning is underway for a summer drilling campaign to continue evaluating this prospective area of the Lac de Gras region.

North Arrow has competed a 302 line km helicopter-borne VTEM Plus time domain electromagnetic and magnetic survey over the known kimberlites and several additional targets.
