North Arrow Minerals Inc. has confirmed that the PK150 kimberlite at its Pikoo Diamond Project in central eastern Saskatchewan is a “significantly diamondiferous” kimberlite. The company has also confirmed that the PK312 is “diamond bearing” and that it has discovered a new kimberlite, PK311.

The analyses off PK150 and PK312 have come from drill core samples recovered during the spring 2015 exploration drilling programme, it said.

A company statement said that caustic fusion analyses of 323.02 kg of kimberlite from PK150 have resulted in the recovery of 487 diamonds larger than 0.106 mm sieve class, including 9 diamonds greater than the 0.85 mm sieve class. It added that the weakly magnetic transitional kimberlite discovered at the eastern end of PK150 has returned diamond counts consistent with the remainder of the kimberlite.

North Arrow also announced that a 14.5 kg sample from hypabyssal kimberlite PK312 has returned five diamonds, confirming the PK312 kimberlite dyke as diamond bearing.

It also said that significant numbers of kimberlite indicator minerals (KIMs), including pyrope and eclogitic garnet and ilmenite, have been recovered from drilling at PK311, which has been confirmed as a new kimberlite.

This takes the number of discrete kimberlite occurrences within the Pikoo Project to seven.

Ken Armstrong, President and CEO of North Arrow, commented "These new diamond results from PK150 are consistent with those reported from the 2013 discovery drill holes and confirm PK150 as a significantly diamondiferous kimberlite with increasing size potential located less than 20km from road and power infrastructure in Saskatchewan. Planning is underway for a detailed follow up geophysical program in advance of a winter drilling program to further delineate PK150 and the other kimberlites on the property, as well as to test new targets."
