DIAMONDS: Drilling at Orion kimberlite reveals 3.25-ct stone

SASKATCHEWAN – Shore Gold of Saskatoon has been drilling 12, large diameter holes in the Early Joli Fou (EJF) and Pense kimberlites at the company’s Star-Orion South diamond project 60 km east of Prince Albert in the Fort a la Corne area. The goal is to upgrade the inferred resource to the indicated category as the feasibility study is revised.

The material collected included 412.63 kg from the EJF intersection grading 12.0 cpht, 134.82 kg from the Pense intersections grading 4.1 cpht, and 114.37 kg grading 1.6 cpht from other intersections.

The largest diamond, a white stone weighing 3.25 ct, was recovered from the EJF intersection. Three other notable stones were also found – 1.15 ct pale brown, 1.09 ct white, and 1.04 pale brown. Shore says the presence of these large stones in such a small diamond parcel supports the coarse size frequency of the diamond population in the Orion South kimberlite.

The company is optimistic that a larger estimate of resources will be made. The 2011 feasibility study estimated probable reserves at 279 million tonnes containing 34.4 million ct of diamonds at a weighted average price of US$242 per carat. Mining that reserve will take 20 years. In addition to the reserve estimate, the Star and Orion South Kimberlites have inferred resources containing 15.7 million carats.
