North Arrow Discovers Three New Kimberlites at the Pikoo Diamond Project, Saskatchewan - Seite 3

A fourth target, drilled in the Pikoo East target area, intersected a black, magnetic mud rich unit with local green to white carbonate fracture fillings and veinlets crosscutting an adjacent country rock breccia unit. This unit is presently not considered to be kimberlitic but remains inconclusive subject to more detailed logging.

PK150 Kimberlite drilling

A total of seven drill holes further evaluated the PK150 kimberlite and related structures. The kimberlite has been extended to a strike length of approximately 150 m and to a depth of 199 m below surface. The two most significant kimberlite intercepts from the current drilling are 106.0 m (DDH 15PK16) and 127.5 m (DDH 15PK18). These two holes were drilled at steep angles (-80 degrees) from north to south and intended to maximize kimberlite recovery for analysis of diamond content and provide deep contact information. Drill hole 15PK34 (-44/350) stepped out approximately 50 m to the east of the 2013 drilling and cut a 30 m interval of kimberlite (21.5 m estimated true width) that displays textures typical of Kimberley-type pyroclastic kimberlite. The 15PK34 kimberlite intercept also has comparatively low magnetic susceptibilities and is well removed to the east of the high intensity magnetic response that defined the original PK150 geophysical target. Drill hole 15PK19 (-50/225) appears to cut off PK150 to the west, however DDH 15PK12 (-50/180) tested a structural target approximately 250 m west of DDH 15PK19 and encountered a narrow, 5 cm kimberlite dyke, suggesting potential for additional kimberlite discoveries to the west of PK150.

Two drill holes retested target PK151 located approximately 500 m to the east of PK150. One of the holes (15PK14; -50/195) encountered an approximately 80 cm wide coherent kimberlite dyke approximately 40 m east of a similar dyke discovered in 2013 (DDH 13PK10). The magnetic feature that defines the primary PK151 target has been explained by a zone of elevated magnetic susceptibilities within granodiorite country rock.

Kimberlite was not encountered in drill holes testing three additional discrete magnetic targets. However, the areas local to all of the kimberlites so far discovered within the Pikoo Project are associated with well-defined KIM trains and remain prospective for additional, larger kimberlite bodies.
