Location: east central Saskatchewan; 140 km east of La Ronge, 10 km north of Deschambault Lake, 30 km west of Pelican Narrows. DigiGeoData Map on the Flin Flon - La Ronge Area
Size: 39,753 ha
Ownership: 100% North Arrow
Stage: drilling and target generation; ten discrete kimberlite occurrences drilled to date, five of which have proven to be diamondiferous.
See October 2022 till sampling program two minute video in support of 2023 drill program.
Closest Infrastructure: power and roads within 6 km of the property’s southern boundary (SK Hwy 911) at Deschambault Lake.
The Pikoo claims were originally staked in February and March 2011 on the basis of regional kimberlite indicator mineral ("KIM") sampling in the Sask craton of north-central Saskatchewan. The regional sample results suggested the potential for multiple kimberlites or kimberlite clusters within a 15km by 20km source area covered by the claims.
Tighter spaced follow-up till sampling in areas that showed the most indicator grains from regional work brought the focus to two distinct source areas, the North Pikoo train and the South Pikoo train. Both of these areas were drill-tested in July of 2013 by North Arrow as part of a 2000 meter program that earned the company an 80% interest from Stornoway and resulted in the discovery of a new diamondiferous kimberlite field for Canada. The remaining 20% was later acquired from Stornoway and announced in February 2017.
On April 4, 2016 at the conclusion of the spring 2016 drilling program, North Arrow announced nine to possibly eleven, discrete kimberlite occurrences had been identified on the property. Five of which proved to be diamondiferous.
Kimberlite PK150 still remains the most significant discovery to date measuring 10-15 m wide, 150 m in strike length, and traceable to 199 m (remains open past that).

The 2016 program also included the collection of 102 till samples throughout the property. An additional 42 till samples were taken in 2017 in the northern and southern parts of the property to better define the North Pikoo, South Pikoo and Bear Lake KIM trains in an effort to identify additional drill targets prior to renewed exploration drilling on the property. Additional staking was conducted in the fall of 2018 and announced November 19 2018 expanding the land position to 41,893 ha. Short till sampling programs were conducted in September of 2021 and in October 2022 (see video of program highlights and lowlights here) to continue to refine and define new kimberlite targets for a drill program proposed for 2023.
