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.

Summary

Location: east central Saskatchewan; 140 km east of La Ronge, 10 km north of Deschambault Lake, 30 km west of Pelican Narrows.
Size: 33,374 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.
Closest Infrastructure: power and roads within 6 km of the property’s southern boundary (SK Hwy 911) at Deschambault Lake.


Highlights


Overview

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.

On April 4, 2016 at the conclusion of the spring 2016 drilling program, North Arrow announced nine to possibly eleven, discrete kimberlite occurrences have been identified on the property.  Five of the kimberlites have been tested and proven to be diamondiferous.  PK 150 represents the only significantly diamondiferous kimberlite discovered on the property so far. 

PK 346 is interpreted as a near vertical, NE trending body with a true width of approximately 16 m. Caustic fusion analysis of a 118 kg sample of PK 346 did not contain a significant population of diamonds as announced on July 25, 2016.  The kimberlite has also proven to not be the source of high-interest pyrope garnets found in till samples down-ice from the body which suggests another kimberlite with a more significant mantle sample must exist in the area.

Kimberlite PK150 still remains the most significant discovery to date measuring ~10-15 m wide, traceable to 199 m and open at depth.  An eastern step out hole drilled in 2016 expanded the 2015 model slightly more to the east but until the new data is integrated into the model, the strike length is estimated to be approximately 150m.

  1. 2015 drilling; previously reported September 8, 2015.
  2. Compiled caustic fusion analyses from 2013, 2015 and 2016 as reported September 8, 2015, November 5, 2013 and May 31, 2016.
  3. Partial results only; more material pending.

On January 17th, 2017 North Arrow announced the purchase of Stornoway Diamond Corporation's remaining interest in the Pikoo Project bringing the Company's interest in the Project to 100%.  Plans for the 2017 exploration are currently being determined.
