North Arrow Discovers Three New Kimberlites at the Pikoo Diamond Project, Saskatchewan - Seite 2

New Kimberlite Discoveries

The most significant kimberlite discovery of the winter program is PK314, located in the North Pikoo area, approximately 90 m southeast of a narrow kimberlite dyke drilled in 2013. PK314 was tested by four drill holes with kimberlite intercepts of 38.5 m (DDH 15PK30; -45/328); 43.0 m (DDH 15PK31; -45/323); 87.0 m (DDH 15PK32; -70/335; hole terminated in kimberlite at 147 m), and 97.0 m and 57.0 m (DDH 15PK33; -85/270; kimberlite intervals are separated by 44 m of country rock). Dimensions of the body remain poorly understood due to steep local topography and a very complex magnetic background, however, the kimberlite is interpreted as an east-west trending near vertical body with an estimated true width of 25 m and a minimum strike length of 40 m. The kimberlite is described as a dark to light gray, coherent to transitional kimberlite with locally common carbonate segregations. Olivine macrocrysts up to 3 cm, are common with less common ilmenite, garnet and chrome diopside. Country rock dilution is estimated at less than 5% and mantle nodules up to 12 cm are present.

Mr. Armstrong added, "The discovery of PK314 is important for a number of reasons, not least of which is its location immediately up ice from a kimberlite indicator mineral (KIM) anomaly that includes high-Cr pyrope garnet compositions consistent with derivation from the deep upper mantle, well within the diamond stability field. We look forward to testing PK314 for its diamond potential once detailed geologic logging of the drill core is complete."

Two additional new kimberlite discoveries were also made in the South Pikoo and East Pikoo target areas. In the South Pikoo area, less than 80 cm of kimberlite and country rock breccia was encountered in two angled holes drilled 300 m apart along an unnamed target. In the East Pikoo area, 1.5 m of coherent kimberlite was discovered in two angled drill holes testing target PK312 from the same set up, indicating an apparent dip of -70 degrees to the southwest. The PK312 kimberlite contains abundant olivine with common garnet, ilmenite and chrome diopside macrocrysts.
